How it is calculated:
Solar array capacity = panel wattage × number of panels.
Daily energy before losses = array capacity × peak sun hours.
Estimated usable daily energy = daily energy before losses × (1 − system losses).
Monthly output uses 30 average days and annual output uses 365 days.
Actual solar generation varies with location, season, weather, panel orientation, temperature, shading, inverter performance and other site conditions.
