How these numbers were calculated
NASA POWER long-term monthly means on a 1° grid around the city, the monthly method of Duffie & Beckman (isotropic sky, each month's average day), panel temperature from NOCT, 10 % other losses and a 96 % inverter. No shading, snow or product-specific data; expect ±10 % against a detailed tool such as PVGIS. To change the number of panels, their rating, tilt, direction or your roof size, use Blorp's free solar roof tool — every result shows its equation and the numbers used.
