Would you like to power your home with solar energy? It may be easier and cheaper than you think to install solar panels!
Over the last 10 decade, homes with rooftop solar panels have become a trend, an example is Home Depot's decision to start stocking solar panels in 2001. The technology has been available for decades -- NASA has been using solar-powered satellites since the 1960s, and as far back as World War II, passive solar heating systems which turn solar energy into heat instead of electricity)have been used in U.S. homes.
The benefits of residential solar power are obvious because energy from the sun is endless at least for the next 5 billion years. It provides clean energy with no greenhouse-gas emissions and it can save people money on their electric bills.
Solar panels are part of a completely stationary system. So once they're installed, the only thing a homeowner needs to do is to keep the panels clean. Excessive dust and bird droppings on the panels can reduce the amount of sunlight striking them. Dust buildup can reduce the amount of electricity produced by the system by as much as 7%.To build a solar-powered home, it's necessary to make sure there are no shadows on the roof's panel area during the sunniest hours. The more hours the panels spend exposed to full sun, the more efficient the power generation will be.
With solar PV systems, each panel houses a cell made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field. Choose between standard roof-mounted panels or built-in panels which sit flush within the roof, or solar tiles, which completely replace traditional tiling.
While deciding to install a PV solar system it is important to remember that such a system is a long-term investment. In many locations, solar power is a good choice from a financial perspective. Even if the cost of solar power is found to be marginally more expensive than electricity purchased from a utility, homeowners may wish to install solar power to avoid future potential fluctuations in energy costs, or may simply wish to look beyond their personal financial motivations and use solar for green living.
