The maximum energy production is thus roughly 400 Wh per day.

The solar panels are connected in parallel and coupled to a solar charge controller and 550 Wh of lead-acid batteries. Assuming a 33% Depth-Of-Discharge (DoD) and a round-trip battery efficiency of 80%, this gives me a maximum energy storage of roughly 150 Wh

Total electricity use in my office is (on average) 500 Wh per day
