Solar potential of Virginia Beach explained
Virginia Beach receives an average of 4.29 kilowatt-hours of solar energy per square metre per day, measured over four decades of satellite observation. In practical terms, every kilowatt-peak of installed PV capacity yields about 1253 kWh of electricity per year here, assuming a well-oriented system with a typical 80% performance ratio. This is a solid mid-range solar resource: production is meaningful year-round, though winter output drops noticeably.
Frequently asked questions
Is solar worth it in Virginia Beach?
With 4.29 kWh/m²/day of average irradiation, a 1 kWp system in Virginia Beach produces roughly 1253 kWh per year. That is a good solar resource; with current panel prices most systems pay back well within their lifetime.
How much electricity would a 5 kW system produce in Virginia Beach?
Approximately 6,000 kWh per year — enough to cover a large share of a typical household's consumption.
What data is this based on?
Long-term satellite observations from NASA POWER (1981–present) and the PVGIS SARAH3 database, assuming a performance ratio of 80%.
