Test different sun hours and panel wattage without changing your main result.
Calculate your baseline first
It divides your daily energy use by peak sun hours and adjusts for your selected system losses. The result is the approximate PV array wattage needed to produce that daily energy.
Use the average daily peak sun hours for your location and season. A lower winter value gives a more conservative design, while a yearly average may be suitable for grid-tied estimates.
No. Battery Ah depends on battery voltage, usable depth of discharge, chemistry, inverter efficiency and reserve needs. Treat the result as a planning estimate before selecting real equipment.
