Planning estimate: compressor duty cycle, shade, panel angle, heat, wiring, inverter losses and battery management can change the result. Use measured energy data where available.
Formula for the nerds
daily load = Σ watts × hours
usable battery = Ah × volts × usable %
solar yield = panel watts × sun hours × (1 − losses)
runtime = usable battery ÷ net daily draw
usable battery = Ah × volts × usable %
solar yield = panel watts × sun hours × (1 − losses)
runtime = usable battery ÷ net daily draw
