I have a number of 100Ah batteries connected in parallel, and I have a number of 100W solar panels operating outside. If I estimate the efficiency of the solar panels as 25% (based on daylight hours and angle of incidence), and I aim for twice the battery capacity I’ll be consuming in a day, then I can use this program to calculate based on my daily power consumption (in KWh) how many batteries and panels to get:
