How Much Do Solar Panels Cost?
Wednesday, August 31st, 2011Manufacture of small electronic devices powered from the sun began during the early ’70s. Today’s solar panels are able to supply the entire United states of america. In order to “recruit” the sun to make about 4000 towards the billions of kWh needed, it will be necessary to install solar panel systems with an area of 32 000 sq km, which is equal to the area of military training ground in Nevada.
Sunrays falling on top of the silicon solar panel systems, are generating voltage. This will depend on the amount of light falling around the panel. The more light, the harder energy can be generated. Energy by means of electricity (Direct Current, DC) may be used in thousands of ways, from lighting with the bulb to powering the laptop computer. This is obviously an extremely simplified system, but completely functional. To be able to use it used, we need more auxiliary devices, such as voltage regulator, batteries accumulating energy, inverters, etc.
Benefits of solar system are:
- No moving parts,
- Very 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 can you quickly calculate, completely sun so the panel can be assigned to only two 75-watt bulbs. Should be added to the cost of installing of control devices and batteries.
Fortunately, the us government helps to deal with the price of the investment. In most states you can find programs for co-funding the building of domestic solar, wind or water powers. In the state of latest York grants reach 4.5 dollar per watt of installed solar panel systems. In New Jersey, with respect to the size of the installation, as much as 5.5 dollar per watt. It has an opportunity of getting interest-free loan and 25% return from the tax. Thanks to all over the costs incurred can be reduced by 60%
An example:
3-kilowatt system installed by a specialist (around $ 8 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 last cost:9375 dollars.
