1. Rentability and annual electricity production of a grid connected PV system
2. Knowing the PV power (Wp) which battery capacity (Ah) ? 3. Knowing the battery capacity (Ah) which PV power (Wp) ? 4. Knowing the electricity demand (Wh) which PV power and battery capacity (Wp, Ah) ?
Calculations serve as a guide and may vary depending on system quality, PV technology or ventilation (mounting system).
Rough calculation for reference data: inclination 30° and southern exposure of the system. Should there be any departure from the reference data, one should correct the results in accordance with the table below, decreasing the efficiency in per cents.
