Solar Electric, also known as Solar Photovoltaic (PV) can provide electricity to your home for general use. PV modules turn sunlight into electricity, and are typically interconnected with the grid so that excess power can be sold back to your utility company. For more, see net metering.
IMPROVED TECHNOLOGY LOWERS PRICES
Improvements in solar technology and manufacturing efficiency have led to a dramatic decrease in the cost to install solar. Taking into consideration these advances, coupled with the fact current government and utility incentives that may not be available in the future, now is the most affordable time to install solar.
As the graph below shows, solar module prices have declined so much in recent years that very little savings can be achieved by waiting for further technological improvements:
