I am trying to come up with a circuit to control a swimming pool filtration pump and heat pump, using a small solar panel (say 0.5W) to power a 12V/240V relay.
To give some background, I have an array of residential solar PV panels powering the house and swimming pool and I want the pool pumps to switch on automatically when there is a reasonable amount of sun. I don't particularly want to have to connect the main house PV panels to the pumps but I thought if I have a mini panel powering the circuit that it will act as a power source and light sensor. The capacitor is included to even out the input current from the mini panel.
I would be grateful if someone could advise whether this circuit would work and what improvements could be made?
I am a complete amateur/novice so please be gentle!
