How Much Do Solar Panels Cost?

Manufacture of small electronic devices powered through the sun began in the early ’70s. Today’s solar panels are able to supply the entire Usa. In order to “recruit” the sun to produce about 4000 towards the billions of kWh needed, it might be necessary to install solar panels with an area of 32 000 sq km, that is equal to the area of military training ground in Nevada.

Sunrays falling on top of the silicon solar panels, are generating voltage. It all depends on the amount of light falling around the panel. The more light, the greater energy can be generated. Energy as electricity (Direct Current, DC) can be used in thousands of ways, from lighting with the bulb to powering laptops computer. This is obviously a really simplified system, but completely functional. To be able to use it used, we need more auxiliary devices, including voltage regulator, batteries accumulating energy, inverters, etc.

Benefits of solar system are:
- No moving parts,
- Suprisingly low operating costs,
- Easy installation,
- Safe, reduced voltage installation,
- Easy control.

The only drawback is the relatively high expense of solar panel. A 150-watt panel with costs between 600-800 dollars, with respect to the amount that we buy. How will you quickly calculate, entirely sun so the panel may be assigned to only two 75-watt bulbs. Must be added to the cost of installing control devices and batteries.

Fortunately, the government helps to deal with the price of the investment. In most states you will find programs for co-funding the construction of domestic solar, wind or water sources of energy. In the state of recent York grants reach 4.5 dollar per watt of installed solar panels. In New Jersey, with respect to the size of the installation, as much as 5.5 dollar per watt. It comes with an opportunity of getting interest-free loan and 25% return from your tax. Thanks to all over the costs incurred may be reduced by 60%

An illustration:

3-kilowatt system installed by a specialist (around Eight dollars per watt): 24 000 dollars.
State refund $ 4 per watt: 12 000 dollars.
Installation cost: 10 500 dollars.
Tax refund of 25%: 2625 dollars.
The final cost:9375 dollars.
