Solar panels are gaining interest amongst people of this energy crunched world. What are solar panels? They are an array of photovoltaic cells which capture the energy of the solar rays. In simple terms, the solar panels capture the energy from the sun during the day for later use. Solar energy is renewable source of energy and does not get depleted like coal or natural gas. It can be tapped as much as required and used to power all our energy needs. With the invention of solar panels, which has helped mankind tap the solar energy, solar power has become an increasingly powerful source of energy in the last decade or so.

Solar panels are made of crystalline silicon and gallium arsenide. The same silicon is used in the microprocessor chips. The gallium arsenide is very expensive which also makes the initial investment cost of solar panels high. These panels harvest the solar energy and convert it to electricity. The electricity produced depends on how much of energy is harvested. Roughly, a solar sell of 0.2 m in diameter can create electricity of 2 amps of 2 volts when exposed to direct sunlight at the surface of the equator. However, the electricity production is decided not only by the size of the panel but also by the quality of materials used in making the solar cells. With time as well as with wear and tear, the electricity production capacity of the solar cells comes down.

The solar panels are environment friendly and cause no pollution while producing the electricity. It also causes no imbalance to the eco system. The electricity generated by the solar panels can be used to power a whole lot of appliances. Solar power is very commonly used for lighting needs. Solar panels are also extensively used on satellites. Solar energy is a clean source of power for all needs, having no impact on the environment.

Solar power and solar panels are the energy solution for the future. The conventional sources of energy like fossil fuels and natural gas are fast depleting. To meet the energy demands of the future, we will have to make use of cleaner and renewable sources of energy like solar power. The solar panels relieve you of the dependence on the power grid altogether and can meet all household energy needs.

The smaller solar panels are portable and can accompany you in all your travels. These are very handy when you do not have access to other sources of electricity to power smaller appliances. Hand held devices, laptops, calculators and small motorized vehicles run well with the portable solar panels. There are endless applications for the solar panels if you decide to use them.

Solar panels can be purchased from various solar panel producers and distributors. The price varies and is mainly depending on the power production capacity of the panel. These panels are generally installed in open areas like the roof top or open ground to tap maximum direct sunlight. The location of the panel should be such that it is exposed to maximum sunlight all through the year. Proper selection and installation of a good solar panel will ensure that all your energy needs are met.

The high investment cost of solar panels has dissuaded many people to go in for them. However, the cost alone should not be the deciding factor while selecting a means of electricity. The solar panels produce no toxic gases or products in the generation of electricity and helps keep the environment clean and unpolluted. Using solar panels is the least we can do to protect our environment and make our earth a better place for future generations.

Many people are becoming interested in converting to renewable energy with the intention of saving both the environment and their pockets. Converting to solar energy is certainly one of the best routes to take, as the benefits are many. Join in, and you will see why it is worth the investment.

Users of home solar panel systems have significantly reduced or eliminated electricity bills, which in itself satisfies most people after they have installed it. But apart from that, people are happy to know that over produced energy from a solar power system can be sold to the utility company, thereby negating their utility bills. From the environmental angle, solar panels contribute significantly to reduced fossil fuel emission, thereby protecting the environment from further damage. As previously indicated, the benefits are many and worth your while. Now, let us take a look at the costs behind such a worthwhile investment.

The first point to note is that the cost of your solar panel system will depend on what it will be supporting. Most households are fully equipped with televisions, washers, dryers, refrigerators, microwaves, computer, light bulbs and water heaters. Sure you could run through the painful task of calculating the cumulative wattage for all of them over a 24 hour period. That exercise would certainly tell you which appliances consume the most electricity. However, a much simpler method would be to consult your utility bill. You bill should highlight how many kilowatts (kW) you used for the number of days in the billing period. Just divide the total kilowatt hours (kWh) by the number of days to arrive at your average daily consumption.

Your next mission is to determine just how many hours of sunlight your roof receives on a daily basis. As a rule of thumb, most places receive about 5 hours of sunlight a day. Using that as a guide, let us look at an example. If you monthly kWh is 200 for a 30 day billing cycle, then your average daily consumption would be 6.6 kWh. As a starting point, a 1 kW rooftop system can generate about 5 kWh per day, i.e. 1 kW * 5 hours of sunlight. Therefore, a 1 kW system would not be enough to satisfy your 6.6 kWh daily needs. A 2 kW system, however, can generate about 10 kWh per day, making it an ideal size for your daily needs.

So what are the costs? Well, a 2 kW system would cost in the region of $18,000 to $20,000. As the wattage increases, so does the price. A k kW system would cost between $35,000 and $45,000, while an 8 kW system would cost upward of $50,000. However, the good news is that once installed, solar panel systems are virtually cost and maintenance free. Even more good news is that the installed cost of solar panels is expected to continue to drop as thin film panels from companies like First Solar, Nanosolar and AVA Solar become available to the residential market.

Further savings can be derived if you purchase a do it yourself home solar panel system, but whatever route you take, you are bound to reap worthwhile rewards. Make the choice today.

What is a Solar Panel?

It can be defined as a contrivance/device that has capabilities to convert photons of light (a photon is an indivisible unit of electromagnetic radiation) emitted by the Sun and convert it into usable electric energy. It is also known as a “Photovoltaic” panel or module, (a module, in scientific terms, is referred to as “a set of parts or units that can be utilized to develop a more complex structure”). The basis of this energy is the Sun. Sun is an immense globe of gas that is seamlessly emitting out energy in the form of Heat and Light. Solar energy collectors utilize the sun’s energy, which is made up of particles of energy known as photons, and convert it into electrical energy inside a photovoltaic cell or solar cell, which can be used to energize electrical loads.

How does a Solar Panel work?

A semi-conductor, (substances that conduct electricity only under certain conditions) mainly Silicon is used to absorb the photon from the sun’s rays and convert it into electricity. How? At the basic level, two thin sheets of silicon are used, one is “doped” (it is an addition of other elements (impurities) to a semi conductor so as to conduct electricity smoothly) with ‘phosphorous’ and arsenic (5 electrons per atom), which introduces a free electron, to the semi conductor. This is known as an N-type (Negative-Type) semi conductor. Another silicon sheet doped with small amounts of boron (three electrons per atom) leaves a missing electron in the semi conductor. This missing electron leaves a hole making the semi conductor positive and acts as a conductor. This is P-type (Positive-Type) semi conductor.

The principle is simple. When these “doped” thin sheets of silicon are sandwiched together, an electric field is created. If we establish a conduction pathway on the electric field so created by placing a contact grid on the top and bottom of N-Type and P-Type silicon sheets, the electric activity is stepped-up between the “doped” silicon sheets causing a flow of electricity through the pathway.

This is a most rudimentary type of Photovoltaic cell capable of generating 0.75 to 1.5 watts of electricity. To light a small home, one needs a bank or array of cells depending upon the expected usage.

Benefits of Solar Panels:

(1)   You are not dependent on Electric Utility Grid.

(2)   This spells huge financial savings.

(3)   You can live in remote, eco-friendly neighborhoods with Solar Panels providing electricity very cheaply.

(4)   Solar power is renewable energy and is very clean and eco-friendly. Functionally they are superior.

(5)   Maintenance costs are extremely low.

(6)   Solar Panels are very compact, more especially those meant for homes. Every integral part and every accessory of the unit is so designed as to make assembling the whole a very interesting and at the same time extremely easy for the D.I.Y segment. Market prices of a whole unit would be prohibitive. Besides, the price of the unit, the installation expenses by technicians would be a very costly affair. If you purchase the parts and assemble it yourselves, the cost becomes negligible. FOR SOLAR PANELS, D.I.Y. is the way! The easy way!

(7)   Since, solar power is working, NOT ON AC (alternating current) but on DC (direct current), principle, your computers, home appliances which work on DC need not use adapters, avoiding conversion leakage which is common.

(8)   No hassles in paying Electricity Bills. In fact there is no bill.

(9)   The critical factor is the duration and effectiveness of sun in your area.

Other uses of Solar Panel:

Solar energy can be transformed into Heat energy.

a)      Heating of Homes in winter at a very reasonable rate.

b)      Heating water in bathrooms and swimming pools. Compared to AC system, the Solar Panels will provide heating to such appliances very cheaply.

c)      Washing machines and Dishwashers also can be connected to the Solar Panels.

Tax Benefits:

v      On 4th February 2008, The Energy Policy Act of 2005 was allowed to cover almost all homes in the US. This means you can claim tax credits if you have constructed a new house using Solar Panels. The Emergency Economic Stabilization Act of 2008 bestows tax credits for people planning improvements in 2009. The Energy Policy Act of 2005 placed a $2000 credit cap on certain types of Solar Panels. The Emergency Economic Stabilization Act of 2008 eased this cap on Solar Panels. This means if you buy a Solar Grid Panel for $20,000 your tax credit will be much more than the $2000 credit allowed previously.

v      The states of New York, Washington, Florida, Minnesota and Vermont do not charge any Sales Tax on Solar Panels and their parts.

v      The State of California permits you to deduct any interest you may have been paying on energy loans in your tax returns.

v      The states of Virginia and Texas won’t add the value of Solar Panels in your property value. This means that there is no Property Tax on your new Solar Panels.

v      The States of South Carolina, Arizona and New York allow an extra deduction of 25% tax credit on the value of the solar system operating in your home.

v      The State of New Mexico, the most friendly renewable energy loving state allows its residents a $9000 tax credit, if the resident installs a Solar Panel system.

Renewable energy is the future of the globe. It is inexhaustible as long as the sun lives, which is estimated to be many more billion years! No eco-debilitating gases, no global warming, no hole in the ozone layer, no increase in El Nino effect. The existence of water vapor and carbon-di-oxide, which keeps the heat coming from sun in equilibrium, is altered by excessive release of carbon-di-oxide. This is known as Greenhouse Effect. By using renewable energy whole-heartedly, and on a global scale, our eco-system will regain its balance obviating the perils and upheavals waiting to happen.

D.I.Y. System:

It is very simple. What you need is the right mind-set. Henry Ford said: “If you think you can, or if you think you can’t, you are right….” If you think you can, D.I.Y. system makes it even simpler for you to achieve.

Great things are achieved not by knowing everything; in fact great things are achieved only by putting your heart into it.

Cool, arent they?

Installing a solar power for a new home requires plenty of planning. If you don’t have a solid plan in place, then it won’t work. The purpose of having solar power in a home is to help homeowners save on their energy bills.

When everything gets configured with the new home, the homeowner will determine how may solar panels they will need. There are two ways that solar powered panels can be selected: there are those that provide power to all of the needs of the home; the other one connects to the existing power grid.

The homeowner may or may not have to size up the power with a separate system. If they plant to connect to the power grid in their area, then sizing won’t be needed. Use what you have in your budget and do the installation accordingly.

The grid power is the supplement and starts where the solar power system stops. The homeowner should check to make sure that additional components can be installed later on if they want it. Also, they should also see about getting the grid tied into their area.

With the solar power system, there are several places where it can be installed:

– Roof

– Ground area

– Posts

If it is to be installed on the roof, the homeowner needs to make sure that the roof is strong enough to hold a solar panel.

These panels can be heavy. Also, the roof should face the sun for most of the day, if not all day. The more sun exposure the roof gets, the more energy your home will receive. Make sure that the roof is clear of any obstacles, including trees or buildings.

There are different providers that make solar panels. Homeowners can search online to see the different distributors that specialize in the sale of these panels. Or, a store such as home depot could be an option. Before a homeowner has settled on an installer, they need to get at least three quotes before they make a decision.

They should also make sure to check their references. Look out for someone that says to be something they are not. If they’re not sure about who to contact, one thing they can do is to see if any of their neighbors have solar panels. Check to see who the installers were that they used. Ask questions regarding the quality of the installation and the service.

In addition to adding solar power to a home, solar power can also be used for outside lighting and ponds or fountains. The homeowner won’t have to concern themselves with having wires strung all over the place.

The homeowner can qualify for rebates from the government if they have energy efficient appliances. This is another incentive. They can check online to get more information on this program and similar ones.

In the long run, homeowners may end up paying a lot of money for their appliances, but in the long run, will benefit from doing so for many years to come.
