Why New Hampshire's climate shapes your solar panel choice
New Hampshire's 3.9h daily peak sun is lower than the US average, but New Hampshire panels operate in cold ambient temperatures (-20 to +20 C typical), which actually increases panel output 5-10% above STC rating. The bigger challenge is snow load.
Look for panels rated 5400 Pa front load (snow). New Hampshire-specific picks: REC Alpha Pure-RX (5400 Pa), Canadian Solar HiKu7. Bifacial panels can also catch albedo reflection from snow, adding 5-10% winter yield — consider Trina Solar Vertex S+ or LONGi Hi-MO 7 Bifacial. For New Hampshire roofs, 30-40 degree tilt sheds snow naturally and avoids needing manual clearing.
