Technologies to use solar energy include using the sun's heat to produce electricity, passive solar heating and daylighting, producing electricity directly from sunlight and heating water with solar energy.
Frequently asked questions:
Will it work in West Virginia?
Available solar energy is comparable in West Virginia to neighboring states. Below are available kilowatt hours/square meter/day for comparable cities.

How much does a photovoltaic system cost?
A PV system for an efficient home using 5-15 kWh/day ranges from $10,000 to $30,000, according to the New Mexico Coalition for Clean Affordable Energy.
What can the sun's energy be used for?
Solar energy, thermal and photovoltaic, can be used on industrial, commercial and residential buildings that have available south-facing areas.
- Domestic hot water can be directly competitive with gas-fired or electric hot water heating. Systems that utilize the sun with fossil fuel or electric power as a backup can pay for themselves in relatively short periods of time.
- Passive solar can be used to complement heating systems.
- Concentrating solar power (CSP) plants use the concentrated rays of the sun to heat a fluid to steam-generating temperatures, driving a steam turbine electric generator.
- A dramatic growth globally is occurring in the manufacture, sale and installation of photovoltaic systems. Now that West Virginia has adopted net metering, homeowners and building owners alike can partner with the electric utilities and bring energy diversity to West Virginia.
- For technical and general information on net metering in West Virginia, contact the West Virginia Public Service Commission: James Ellars at (304) 340-0331 or firstname.lastname@example.org.
- Contact your electric utility for specific information on net metering in your area.
Where can I get more information?
Below are some good sites to visit:
American Solar Energy Society
Find Solar: Connecting You to Renewable Energy Professionals
Solar Energy Industries Association
The U.S. Department of Energy and National Renewable Energy Laboratory's Open PV Mapping Project, which will provide a Web-based resource for users to easily understand the current status and past progress of the PV industry from the data that show current and recent trends of the PV market. Additionally, users may add their own PV installation data, browse PV data entered by others, and view statistics.
Are there currently any incentives or grants to assist homeowners with solar or photovoltaic installation costs?
The state of West Virginia enacted a $2,000 tax credit for residential solar water heating, solar space heating and photovoltaics. For more information visit Database of State Incentives for Renewables and Efficiency.
No grants are available at this time although the federal government also offers a tax credit, available at 30 percent of the cost, with no upper limit through 2016 (for existing homes & new construction) for:
- Geothermal heat pumps
- Solar panels
- Solar water heaters
- Small wind energy systems
- Fuel cells
