PhotovoltaicThe big attraction for migrating into a photovoltaic (the technical term for solar cells) power system has been the huge decrease in the cost of solar panels, with the system's prices falling 20 percent since last year. Producing solar cells generating only 60 megawatts in 2005, by 2009, it was producing 1,000 MW gigawatt. Beware though, because so many Chinese firms have been pushing it here, there have been so many well-meaning Filipino entrepreneurs offering such solar systems, who however lack the engineering skills or worse, provide you with below-standard but cheap solar panels, usually unbranded ones. Like electric cars, the big advantage of a solar system is that since it has practically no moving system, its usable lifetime is quite long, 25 years believe it or not for the solar panels, eight to 10 years for the lithium batteries, and 10 years for the inverter which converts the solar cells' direct current to the alternate current you use in the house. They should even have a lobby group for the government to provide tax incentives to companies and residences moving to solar power.
