More than one million homes now have solar panels, helped by government subsidies and clean energy policies. Falling equipment prices and competition among installers have driven the average price of a home solar system down 10.6% over the past year to $3.21 per watt, or $16,050 for a five-kilowatt solar array. A federal renewable-energy tax credit can shave another 30% off the total cost.
