About 95% of solar cells are made from the factor silicon, a nonmetal semiconductor which can absorb and convert sunlight into electricity from the photovoltaic effect. Here is the way it works:
power vegetation which have at the very least one megawatt of electric-generation capacity. Technological developments, decrease costs for PV systems, and a variety of money incentives and federal government procedures, especially tax credits and Web metering, have served to significantly extend PV use For the reason that mid-nineties.
