How accurate is this calculator?
This calculator provides a good estimate for off-grid solar system sizing. For precise calculations, factors like seasonal variations, exact panel specifications, and battery storage should be considered by a professional.
What are peak sun hours?
Peak sun hours represent the equivalent number of hours per day when solar irradiance averages 1,000 watts per square meter. This varies by location and season.
Why account for system losses?
System losses (typically 20-30%) account for inefficiencies in wiring, inverters, battery charging, temperature effects, and other factors that reduce overall system performance.
