Solar panels in Harrisonburg, VA

Check your specific roof in Harrisonburg → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Harrisonburg solar system costs
A 21-panel system (8.4 kW) is about right for an average Harrisonburg home using 10,800 kWh a year. It would produce roughly 10,810 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 4,118 | $6,384 | $585 | 10.9 yrs |
| 12 panels | 4.8 kW | 6,177 | $9,576 | $877 | 10.9 yrs |
| 16 panels | 6.4 kW | 8,236 | $12,768 | $1,170 | 10.9 yrs |
| 20 panels | 8 kW | 10,295 | $15,960 | $1,462 | 10.9 yrs |
| 26 panels | 10.4 kW | 13,384 | $20,748 | $1,625 | 12.8 yrs |
Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.
Why Harrisonburg gets 1,514 sun hours
That figure comes from Google's analysis of real rooftops across Harrisonburg — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Harrisonburg reaches about 1,596 hours, roughly 5% better than typical.

When Harrisonburg actually produces

Harrisonburg produces about 2.8× as much in Jun as in Dec — a normal mid-latitude swing. Expect real winter shortfall and summer surplus rather than steady year-round output.
The annual total is measured from Google's rooftop imagery. Its split across months is calculated from solar geometry at Harrisonburg's latitude, not separately measured, so treat the monthly figures as the shape of a typical year rather than a forecast.
