Solar Installation Saves School District $12 Million

It’s a big undertaking for an area whose population is just over 25,000, but Lacey Township, part of the New Jersey Shore region, is ready to install 7,000 solar photovoltaic panels on 120,000 square feet of roof on top of Mill Pond Elementary School.

Racks and rails are already in place, as is the wiring, slated to allow the production of 1,483 kilowatts of power (the local press said 383, but mistakes happen), or an approximate 1.5-megawatt system.

The installation is a result of a December 2008 referendum approving $19,9 million for the solar installation, as well as upgrades like window replacement, boiler upgrades and a new roof, all but the latter aimed at energy conservation.

The referendum met considerable opposition, in a newly emerging recession, but Lacey Township School District estimates – that the solar installation would save $12 million over the 25-year lifespan of the system – obviously instilled some voter confidence.

Since then, slumping solar prices and a contraction in the construction industry have provided even greater savings than formerly anticipated – the system is cheaper to install than expected, and solar prices have come down.

The market for renewable energy credits, or RECS, has also increased, at least in terms of solar. The District estimates RECs sold to utility companies (whose payments have increased from about $450 to about $650 per watt), will provide the District a tidy little cushion.

It’s a win-win for the District and for the local utility, Jersey Central Power & Light (JCPL), which operates under New Jersey’s clean energy mandate of 1,500 megawatts of solar power by 2020.

The solar project will also form part of a new clean energy curriculum at the school, allowing students to learn how solar energy works and to monitor the system via an interactive display.

With new roof installation preceding the solar installation, the panels are not affixed to the roof (which would void the warranty) but instead weighted in place. In spite of that, the solar system is expected to be able to withstand winds in excess of 110 miles per hour, according to Ray Angelini, Inc., the firm that installed solar panels on the Atlantic City Convention Center.

How to Install the Solar Panel Safely?

Solar panel come in various sizes to satisfy a full range of applications. Each Solar panel is made of crystalline-silicon cells. To protect the cells from the most severe-environmental conditions, Solar panel are made of high transmission rate and low iron tempered glass, anti-aging encapsulation material, and high climate resistant and insulation back sheet by hot lamination, with anodized aluminum alloy frame and junction box.Solar panel are reliable, virtually maintenance free power supply, designed to operate efficiently in sunlight. By Solar panel, the solar radiant energy is transformed into electrical energy for using. Solar panel, usually be used as one fittings of PV solar system. A set of basic PV solar system is consisted of PV Solar panel, Solar regulator, solar inverter, and storage battery.

Solar panel can be used in roof PV solar systems, PV stations, building, and other electric generation application etc widely.

The mechanical and electrical installation of solar systems should be performed in accordance with all applicable coded; including electrical codes, building coded, and electric utility interconnect requirements.

Requirements may also vary with system voltage, and for DC or AC application.

How to Choose the installation angle of Solar Panel?

How-to-Install-the-Solar-Panel-Safely.jp

Solar Panel installation Mounting site
Solar Panel can be used on land except for corrosive salt area and sulfurous area.

Excluded applications include, but are not limited to, installations where Solar Panel are likely to come in contact with any salt water or where likely to become partially or wholly submerged in fresh or salt water, examples of which include use on boats, docks and buoys. Don’t install modules in a location where it would be immersed in water or continually exposed to water from a sprinkler or fountain etc.

Modules are designed for a maximum allowable design pressure of 50 pounds per square foot, about 2400Pa, which may correspond to a nominal wind speed of approximately 130 km/h in certain circumstances.

Actual maximum allowable wind speed may be influenced by module type, mounting configuration, location, and other factors. In no case should modules be exposed to pressures greater than 50 pounds per square foot of uniformly distributed wind, snow, or other loading.

Not install Solar Panel near naked flame or flammable materials.

When choosing a site, avoid trees, buildings or obstructions. Modules should be mounted to maximize direct exposure to sunlight and to eliminate or minimize shadowing. Even partial shadowing can substantially reduce module and system output. Furthermore, partial shadowing can elevate the shaded portion internal temperature, which may lower output and shorten module life.
Solar Panel Orientation of installations
Modules may be mounted at any angle from a vertical orientation to a horizontal one. The appropriate fixed tilt angle and azimuth orientation should be used in order to maximize the exposure to sunlight.

Incorrect orientation of modules installation will result in loss of power output. Modules connected in series should be installed at same orientation and angle. Different orientation or angle may cause loss of power output due to difference of amount of sunlight exposed to the modules.

In the Northern Hemisphere, Solar Panel should face south, and in the Southern Hemisphere, Solar Panel should face north.
Solar Panel tilt angle
Solar Panel produce the most power when they are pointed directly at the sun. For installations where Solar Panel are mounted to a permanent structure, Solar Panel should be titled for optimum winter performance. As a rule, if the PV system power production is adequate in the winter. It will be satisfactory during the rest of the year. The Solar Panel tilt angle is measured between the Solar Panel and the ground.
Use fasteners to fasten the Solar Panel to the mounting support structure. Solar Panel should be bolted to support structures through mounting holes located in the frame’s back flanges only. Stainless-steel bolts, with nuts, washers, and locks washers, are recommended for module mounting. Creation of additional holes for mounting is not recommended and will invalidate the warranty. Solar Panel should not be mounted by supports at the ends.

Mounting support structure should withstand forces from wind and snowfall pressure etc. Mounting support structure should use proper materials and corrosive treatment.

Installation the Solar Panel should has proper ventilation. A clearance of 4.5 inches (about 115mm) or more behind the Solar Panel is recommended to permit air circulation and cooler solar panel operation. Elevated temperatures lower operating voltage and power, and shorten solar panel lifetime. Clearance of 1/4 inch (6.35mm) or more between solar panel is required to allow for thermal expansion of the frames.

How to wire solar panel on installation ?

How-to-wire-solar-panel-on-installation.

1)Blocking diodes

Blocking diodes can prevent nighttime battery discharging caused and prevent solar panel from loss of array output and being damaged or destroyed by reverse current flow.

Blocking diodes should be installed in series with each solar panel or series string to prevent possible back flow of energy through the solar panel when solar panel or strings are connected in parallel or used in conjunction with a battery.
2)Overcurrent protection
Whenever necessary to comply with local codes, use a fuse or circuit breaker, rated for the maximum series fuse rating of the module and the system voltage.

Always fuse the connections at the battery for safety. Refer to the solar panel rating label (on solar panel) for recommended fuse size. Also, refer to the charge controller owners manual.

All electrical components should have ratings equal or greater to the system rating. Do not exceed the maximum allowable system voltage as listed on the solar panel label.

3)Grounding
All solar panel frames should be grounded for safety. The support structure must also be grounded unless they are mechanically connected by nut and bolts to the grounded solar panel.

Attach a separate ground wire to grounding holes on solar panel frame with a self tapping screw. solar panel frame is provided with grounding holes. Stainless-steel bolts, with nuts, washers, and locks washers, are recommended for module grounding. The ground wire should be at least the same size as the electrical conductors, ground wires greater than 10AWG is recommended.4)solar panel Wiring
solar panel are equipped with factory installed wires and quick connectors. Modules have been designed to be easily interconnected in series.
One solar panel has a pair of male and female waterproof cables and connectors for electrical connection, that are pre-wired inside the junction box. The cables have obvious marks of the positive and the negative.

The connectors at the opposite end of these wires allow easy series connection of adjacent solar panel by firmly inserting the male connector of a solar panel into the female connector of an adjacent solar panel until the connector is fully seated.

For a series electrical connection, should connect positive (+) connector of the first solar panel to the negative (-) connector of the following solar panel. For a parallel electrical connection, should connect positive (+) connector of the first solar panel to the positive (+) connector of the following solar panel.

The cable typically used to interconnect the solar panel should be stranded or solid copper single-conductor type, rated sunlight resistant, for solar panel and solar panel wiring that is exposed to weather, from 12AWG (4.0mm2) up to 14AWG(2.5mm2) gauge copper wire.

The maximum and minimum diameters of the cable that may be used with the cable connector are 8mm and 6mm respectively. A separate return wire or wires may be required to run the positive and negative terminations of the series string of modules to the load. Male and/or female connectors pre-attached to wires may be used at the string terminations for return wire connections and/or for source circuit box terminations. solar panel have bypass diode(s) installed.

How to Maintenance the Solar Panel?

It is not uncommon for a remote site to be checked but once per year. Under most conditions, normal rainfall is sufficient to keep the Solar Panel glass clean.

Clean the glass with a soft cloth using mild detergent and water. Solar Panel that are mounted, fiat ( 0°tilt andle) should be cleaned more often, as they will not self-clean as effectively as Solar Panel mounted at a 15°tilt or greater.

It is advisable to perform periodic inspection of the Solar Panel for damage to glass, backskin, frame and support structure. Check electrical connections for loose connections and corrosion. Check if mounting support structure and modules are loose. Check connections of cables, connectors, and grounding. Change Solar Panel must be the same kind and type, if need. Solar Panel can operate effectively without ever being washed, although removal of dirt from the front glass can increase output. The glass can be washed with a wet sponge or cloth, wear rubber gloves for electrical insulation.
 

Solar Panel Safety precautions

Solar Panel installation and operation should be performed by qualified personnel only. Children should not be allowed near the solar electric installation.

Avoid electrical hazards when installing, wiring, operating and maintaining the module. Solar Panel produce DC electricity when exposed to light and therefore can produce an electrical shock or burn. Solar Panel produce voltage even when not connected to an electrical circuit or load. Solar Panel produce nearly full voltage when exposed to as little as 5% of full sunlight and both current and power increase with light intensity. Do not touch live parts of cables and connectors. As an added precaution, use insulated tools and rubber gloves when working with Solar Panel in sunlight.

Fall of Solar Panel from high place will cause death, injury or damage. Do not drop Solar Panel or allow objects to fall on Solar Panel, never leave a Solar Panel unsupported or unsecured. If a module should fail, the glass can break a Solar Panel with broken glass cannot be repaired and must not be used.

When installing or working with Solar Panel or wiring, cover module face completely with opaque material to halt production of electricity. Solar Panel have no on/off switch. Solar Panel when exposed to sunlight generate high voltage and are dangerous, Solar Panel can be rendered inoperative only by removing them from sunlight, or by fully covering the front surface with opaque cloth, cardboard, or other completely opaque material, or by working with Solar Panel face down on a smooth, flat surface when installing or maintaining.

Do not artificially concentrate sunlight on the Solar Panel.

Solar Panel can produce higher output than the rated specifications. Industry standard ratings are made at conditions of 1000W/㎡ and 25℃ cell temperature. Reflection from snow or water can increase sunlight and therefore boost current and power. In addition, colder temperatures can substantially increase voltage and power.

Solar Panel are intended for use in terrestrial applications only, thus excluding aerospace or maritime conditions or use with sunlight concentration.

It is recommended that the Solar Panel remains packed in the box until time of installation.

Work only under dry conditions, with a dry Solar Panel and tools, since sparks may be produced, do not install Solar Panel where flammable gases or vapors are present.

Do not drill holes into Solar Panel frame as it will void warranty. Solar Panel ate constructed frame as it will void warranty.
Handled with care, if the front glass is broken or if the polymer backskin is tom, contact with any module surface or the frame can produce electrical shock. Particularly when the Solar Panel is wet, broken or damaged modules must be disposed of properly. Do not disassemble, bend, impact by sharp objects, walk on, and throw or drop etc. keep back surface free from foreign objects. Avoid sharp edges.

Use Solar Panel for its intended function only follows all Solar Panel manufacturers’ instructions. Do not disassemble the module, or remove any part or label installed by the manufacturer. Do not treat the back of the Solar Panel with paint or adhesives.

If not otherwise specified, it is recommended that requirements of the latest local, national or regional electrical codes be followed.

Retain this installation manual for future reference.

Notes
The electrical characteristics are within ±5 percent of the indicated values of Isc, Voc, and Pmax under standard test conditions (irradiance of 100mW/㎝2, AM 1.5 spectrum, and a cell temperature of 25℃(77°F).

Under normal conditions, a photovoltaic Solar Panel is likely to experience conditions that produce more current and/or voltage than reported at standard test conditions. Accordingly, the values of Isc and Voc marked on this module should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse sizes, and size of controls connected to the PV output.

The Cost And Benefits Of Solar Power Explained As Renewable Energy Becomes A Viable Alternative

As fuel costs continue to rise, alternative sources of energy become more attractive to individuals and businesses. For those who are concerned about pollution or about the depletion of natural resources, renewable energy sources such as wind and solar power have presented themselves as possible alternatives to oil and coal.

Yet as increasing demand for clean, renewable energy drives a growing market for solar energy products, many people are left wondering what such systems cost and where those costs come from. Sunlight itself is free to everyone, yet the types of technology used to harness the power of sunlight can be costly. If you are interested in purchasing solar power products for your home or business, knowing what you will be paying for can help you make the best investment.

Two of the main types of products that take advantage of solar energy are passive and active solar products. These two types of systems differ in how they are constructed and can also differ greatly in cost. Passive solar technology can be used to heat air or water using the sun’s energy. Unlike an active solar application, passive solar set-ups accomplish their task without the use of additional electrical components, such as fans that need an external electricity supply.

Some solar space heating or water heating systems are active solar heating systems that have various components that require external power sources. Because of their simplicity compared with active systems, passive solar heating systems generally have the lower cost of the two.

In addition to these solar heating systems, there are also solar power systems available. Rather than using the sun’s energy for heating applications, these systems convert solar energy into electricity. These products are often constructed from hundreds of a type of solar energy collection cell called a photovoltaic cell. The name of this type of cell makes reference to the fact that the cell generates electricity from light. As sunlight falls on a photovoltaic cell, the light’s energy is converted into electricity that can then be used to power many kinds of electronic devices.

Because of the complicated technology involved, these kinds of solar power systems can be very expensive. However, the cost savings may eventually more than pay off your initial investment in the solar cells.

When considering what kind of solar heating or power system to install in your home or business, be sure that you are purchasing your equipment from a reputable manufacturer or distributor who will be able to help you with any necessary repairs, periodic upgrades or additional conversion from traditional systems to a solar-powered system.

The best service will often be the most expensive, but you may be able to find grant funding to help offset the costs of equipment or installation. Many states offer grants for conversion to solar power, and doing some research into the grant programs for solar power systems in your area will help you get a sense of the how much financial assistance is available.

Major Benefits of Using Commercial Solar Power

Commercial solar power when used in the business world greatly benefits businesses of all types. The technology that produces solar power allows a business to thrive in an easy way. There are several advantages of choosing to install commercial solar power system. Let’s see which benefits one can obtain after installing a solar system into their businesses.

Deduction of operating charges: Producing your own electricity, your business not only protects itself from the rising of power bills. After the initial cost of implementing the solar system technology, it is absolutely free to use solar power. There is no annually or monthly “solar bill” like you pay for using traditional electricity. Your business’s power consumption will be cost-free. You won’t require to think like how, but, or if about unexpected electricity bills.

Government advantages and bonuses: The government offers bonuses and monetary benefits to all who use green energy for the production of electricity. There is a fact that if an individual is generating excess power and stay connected to the power grid, then the local power supplier must buy back this excess power back into the power grid.

Use of commercial solar power does not need any maintenance: Solar panels are designed for producing solar power from sunlight. The system does not need any type of maintenance for several years once it is installed.

Great return on investment: If you are looking at the initial cost of installing a commercial solar power system, take few minutes more and see what you can imagine. If you know the benefits of solar power, then you can easily understand how much it can be beneficial for you in the future. You can also generate excess energy which you can then sell for public consumption to your local electricity suppliers. The local power suppliers are responsible to repay you for that extra energy.

Depending on where your commercial building is situated, commercial solar power setups can help reduce your dependence on traditional power. Collect the maximum amount of electricity from the sunlight to operate your electric appliances. Once the system is installed, your power usage will not produce high utility charges because solar system generates enough power to meet with your needs.

The effects of using traditional energy sources are in front of your eyes. You can see how oceans are heating up, weather patterns are changing, the ice on mountains is melting, and global warming is increasing and much more. Thus, go green by installing solar system and save the environment from being harm.

If you are planning of harvesting the benefits of solar energy, the primary thing to do is to look for solar installers. While there are several installers available, it is vital to choose a solar company that offers quality installation work at competitive prices. You can get different solar quotes from registered solar panel installers by linking up with a right portal. You won’t require making multiple phone calls because the right portal will help you in getting quotes for solar power installation.

Why Home Photovoltaic (PV) Systems Are So Expensive?

Many people like the idea of using a solar power system for their homes. Solar system has the potential to reduce their monthly energy consumption because the home power requirement is supplemented by free energy from the sun.

However, many home owners are not using solar energy due to its high initial investment. A complete solar system capable of supporting a small house can cost upwards of $35,000 if you were to engage the service of a professional contractor. But why are the solar components so expensive? One main reason is the high manufacturing cost.

During the manufacturing process, silicone material must be used to make the solar panels which consist of multiple photovoltaic cells. Silicone material is used because it has a high resistance to withstand Ultra Violet (UV) rays and moisture.

Silicones can operate over wide range of temperature and has so many beneficial characters such as high dielectric constant, optically transparent and many more. Hence, silicones are very costly and yet they are very reliable in terms of performance and durability.

A typical solar panel from a hardware store will have 10 – 20 units of Photovoltaic (PV) cells. All these cells are linked together in series so the combined power output is sufficient to charge a deep cycle battery.

Other components that make up the solar energy system are the charge controller, power inverter, voltage meter, amperage meter etc. Connecting all these components together and making sure they work properly can be quite a challenge. You must understand the science of electricity and be able to do some electrical engineering calculation.

Some of the cost of a home solar system will also goes to the contractor’s skill and knowledge in setting and configuring the system for you. Alternatively, you can spend 3 years studying to get a degree in electronic and electrical engineering so you can setup the system on your own.

How Much Does Solar Energy Cost?

“How much does solar energy cost” is a difficult question to answer but this article will hopefully give you some good pointers.

The cost of using solar energy is next to nothing after the initial investment of setting up your solar power system for your home. The amount of money that you will pay for the equipment is determined by a number of variables.

Factors that determine the cost of solar energy include your electricity requirements, the amount of sunshine that is available to charge the solar panels, size of the place where the panels will be used and incentives given by the government to people using ‘green’ technology.

And governments and states are recognizing the benefit to society at large to encourage the use of renewable energy sources. Clearly this would also have the effect of reducing the obligation on government to provide power which is an increasingly onerous task because of the depletion in fossil fuel supplies.
Taking into account the above mentioned variables, here is a rough estimate of the cost of solar energy.

Water Heating System: The cost of a solar water heating system is $2,000-$4,000.

Photovoltaic System: The price of a solar panel depends on its wattage. A 1 kW system costs between US $8,000 and $10,000. For an average sized family, 1.5 – 3 kW solar panels are required, which cost between US $13,000 and US $27,000, without rebates.

You can save a lot of money on solar panels with the help of government rebates and tax credits. For example, say you live in California and have purchased a 2.5 kW system for $22,500.

The government rebate on this system will be $7000 (2500 watt x $2.80 per watt rebate = $7,000). Also subtract the tax credit amount of $ 1,163 from the sale price (7.5% of system cost after rebate. $22,500 – $7,000 x 7.5% = $1,163).

It should be kept in mind that the example given above is an estimate and other factors will play a part in determining the final cost price of a solar energy system.

You can reduce these costs enormously though by building your own solar panels which can be built at a fraction of the cost of buying ready made units.

Solar Panel Installation Procedure


The process of solar panel installation is easy if you know what to do. A thorough understanding of the installation process helps home owners to choose the right devices and equipments to produce the most desired results. In this article, we’ll discuss solar panels and its installation process.

Define: Solar Panels

Solar panels are special devices capable of capturing the light emitted by the sun and convert the absorbed light into the electricity. Solar panels are the most important equipments of the solar power system. Therefore, one should always choose the highest quality of solar panels regardless of the selection of the installation process.

Solar Panels Installation: The Process

Once you have decided to install solar panels at your home or office, gathering relevant information is must. Educate yourself a bit to develop an understanding to choose the best to complete the entire installation process. Gathering information is important as different solar panel brands need to be installed differently. Also, the installation process of solar panels varies with their sizes. Hence, a good understanding is important while installing solar panels.

You can hire a professional installer if you are not able to install the system of your own. Usually, installing the panel without prior experience is not safe as it could be a risky job to do. For example, if you are planning to install the solar panels onto the roof, you should be careful about handling the wires and other equipments used in the process. You may have to climb ladders and do such works, so prepare yourself or take the help of professional installers who holds some experience in the solar panel installation process.

In general, solar panels are installed on a low pitched shingle or metal roof. However, many people prefer installing their panels on a flat roof..

Popularity of solar panels

Solar energy is clean and renewable source of energy and has always showed much promise in terms of its adoption in our daily lives. However, the progress has been rather slow over several decades of this technology being available. The slow pickup in popularity of solar panels over last few decades has been due to the cost of solar panels and the area required for installing them. There are two broad categories of solar panels that are available in the market – one which are used for heating and the other which are used for generating electricity, made of photovoltaic cells. Adoption of solar panels for heating has become reasonably popular, but the penetration of solar panels for electricity has been on the lower side. Cost and required installation area has contributed to the lack of interest from potential customers.

However, things are changing in UK over last few years and the demand for solar power has seen an uptick. While some really caring souls are moving to green energy source for the environment, many others seek financial benefit in doing so. And why not, there has been continuous decline in prices of solar panels over last few years and these are now more affordable than ever before. The running cost is almost negligible. Also, the government has given enough financial incentive in UK to boost the demand for solar panels.

The launch of Feed-in-Tariff (FiT) program in UK in 2010, the popularity of solar panels saw a significant jump. Under the FiT program, government said it would pay 43.5p to every household for every kilowatt hour of solar power they generate. In addition to this, households could sell the excess power back to National Grid for 3.1p per kilowatt hour. As per estimates, a typical domestic solar system could generate a benefit of around £1200 for a household. Considering the cost of installation of a typical domestic solar energy system to be around £10,000, this program offered great return on investment. This led to significant increase in popularity of solar panels. In the financial year 2010-2011, UK saw solar power capacity addition of 77MW through 28,602 solar panel installations. But this is very small as compared to a country like Germany, which added 7500MW to its solar power capacity. Nonetheless, there is a significant shift in terms of popularity of solar energy and that is encouraging. However, in 2012, there is a risk of the potential deceleration in demand of solar panels due to changes in Feed-in-Tariff program of the government. The government wants to reduce the tariff to 21p per kilowatt hour as the program is putting more strain on the government than what was expected initially, which was result of great response to the government scheme. While, the 21p tariff still offers a great return on investment considering the cost of solar panels are declining sharply, the demand for solar panels in the coming years should continue to remain strong.

In UK, the popularity of solar panels bolton, South Yorkshire, Devon, Hampshire, West-Yorkshire, Derbyshire, Cornwall and richer parts of counties around London, as suggested by the number of installation last year has grown.

The recent trend in demand for solar power is encouraging. British government has an ambitious target of 22GW of solar power capacity by 2020. The target looks quite ambitious indeed, but proper implementation could lead the demand in the right direction. For future demand, a lot depends on the cost of solar panels as economies of scale across the world should bring the cost significantly down. Expect the popularity to improve as the initial cost of setting up solar power comes down. By the looks of it, the future for solar power looks bright and sunny.

Solar Shingles

With the rapid advancement of solar power, new products are entering the market containing “integrated solar panels”.

For example, solar shingles. Essentially, these are ordinary roof shingles which are made out of photovoltaic materials. They perform the same function as ordinary roof shingles, with the added capability of producing electricity.

The advantage of these thin “solar panels” is that they can now be integrated right into one’s building materials – so instead of having solar panels on your roof, you would now have a solar roof.

Aside from being more desirable from an aesthetic standpoint, this also eliminates the need for bulky and heavy “traditional solar panels” to be installed.

How are Solar Shingles Made?

Advancements in solar power technology, such as the inventions of solar ink and other combinations of semi-conductors, have made it possible to combine or include photovoltaic materials in with a wide range of other products and materials. Solar cells no longer need to be made out of bulky heavy-weight silicon panels. They can in fact be printed on just about any type of material – such as metal, plastic, and others. Researchers have even found methods of producing organic photovoltaics, although that is, at the moment, still in an entirely experimental phase.

Benefits of Solar Shingles

– Attractive style

– Fully integrated shingle roof

– Lower electric bill

– Free electricity

– Pollution-free power

– Increased home value

– Protects the environment

– Exceptionally durable

– Great investment

– Significant state cash rebates available

– Federal tax incentives available

Costs and Financing

To be honest, right at this moment solar shingles might still seem expensive to some, but as any new technology develops its products become cheaper with time. However it does look as though the cost will be considerably lower than installing a comparable set of conventional solar panels. In one recent example, the entire cost of a home solar shingle installation was approximately $16,000, with a $12,000 tax rebate. This brought the entire cost to only $4000. That’s considerably lower than the usual cost involved in installing a home solar power system – but one has to keep in mind as well that the cost of tiling or shingling a roof is covered at the same time. These are, after all, shingles as well as solar panels.

Clean energy cash incentives and tax rebates are available at a federal level, and most states also have a clean energy or sustainable energy source rebate program. This, combined with energy savings, does make them affordable, and will in most cases pay for itself over time.
