Photovoltaics are a clean, free way to harvest electrical power from the sun’s rays through the use of solar cells. Solar power is a never-ending supply of electricity that can greatly reduce your dependancy on utility company power and your electric bill. This free power source isn’t really free though. In order to harvest this power source, you’ll need an initial investment to capture the sun’s rays.
Solar cells are pollution-free and can be mounted in areas easily accessible or areas that keep them free from anyone coming into contact with them. They can be mounted in yards or atop the roof of your house. These solar cell panels are connected together to form a layout of panels that produce all or part of your power that your home requires.
Solar cells produce direct current (DC) and is stored in batteries and/or is coverted to useable alternating current (AC) that your home runs on every day. To accomplish this feat, the solar system implements a power inverter that converts DC to AC power.
Since it is only sunny half of the day, it is likely you’ll still require the utility company feed to power your home at night, which should translate into a 50% savings on your electric bill. But with this savings, there is the initial cost of the unit. For instance, a typical five-kilowatt system will cost between $30,000 and $40,000.
On the up side of the equation, the government offers one-time grant programs that pay up to $25,000 on a five-kilowatt system. You may also qualify for deductions on your tax returns. As an added bonus, your system may produce more power than you can use. This gives you the opportunity to sell the utitlity company power back. Now you are generating an income from your investment.
