| 10 kW | $29,500 | $8,850 | $20,650 | 12,556 kWh | $1,632 | 12.7 years | $20,983 | $34,997 |
Solar Energy in Virginia: What You Need to Know
Virginia passed the Clean Economy Act mandating 100% clean energy by 2045. Solar adoption is accelerating with expanding net metering and utility solar programs through Dominion Energy.
Electricity Rates in Virginia
The average residential electricity rate in Virginia is 13 cents per kWh, which is below the national average of approximately 16 cents per kWh. Lower electricity rates mean the payback period is longer, but the 25-year savings are still substantial. As electricity rates continue to rise (averaging 3% per year nationally), the value of solar ownership increases over time.
Peak Sun Hours and Solar Production
Virginia averages 4.3 peak sun hours per day, which is moderate but still viable for residential solar. Many successful solar installations operate across the Northeast and Midwest with similar sun hours. Modern panels are increasingly efficient even in diffuse light conditions. A 6 kW system in Virginia produces approximately 7,534 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Virginia Solar Incentives and Programs
No state tax credit. Net metering at retail rate for systems up to 25 kW. SRECs created but not a formal market yet. Property tax exemption for solar (at local option). Sales tax exemption for solar equipment.
Incentive Summary for Virginia
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Available
- SRECs: Not available
- Avg. Installation Cost: $2.95/watt (before incentives)

Environmental Impact of Solar in Virginia
Installing a 6 kW solar system in Virginia offsets approximately 6,442 pounds of CO2 per year, which is equivalent to planting 53.1 trees annually. Over the 25-year lifespan of your solar system, that adds up to roughly 161,050 pounds of avoided carbon emissions. Choosing solar energy is one of the most impactful steps a homeowner can take to reduce their carbon footprint and contribute to cleaner air in Virginia communities.
