What if it rains and I've got a photovoltaic (PV) (solar electric) system?
A question I get all the time!!!
Well it's raining now and my 1 KW PV system is generating 190 Watts. It's a thin film system so it will be interesting to see how crystalline systems are performing.
We are currently using less than 190 Watts in the house, therefore we have excess energy being used to recharge the batteries. If we have a power failure now or Load Shedding, we won't use our batteries.
