Why Virginia's climate shapes your solar panel choice
Virginia's 4.6h daily peak sun is among the highest in the US, but heat is also the enemy of panel efficiency. Every panel loses ~0.3-0.4% efficiency per degree C above 25 C ambient — meaning a typical panel rated at 22% drops to 19-20% real-world output during Virginia summers.
For Virginia, prioritize panels with temp coefficient at or below -0.30%/C. Top picks in this range: REC Alpha Pure-RX, Q.CELLS Q.TRON, Maxeon 7. The 2-3% efficiency edge over commodity panels pays back roughly $84 over 25 years on a typical 8 kW system at Virginia's $0.14/kWh utility rate.
