Hi all, I'm designing a battery-less solar blower setup...
1 panel 265W SolarWorld Mono Panel - Voc = 38.1V, Vmpp = 31.9V, Lsc = 8.82 amps, Lmpp = 8.33 amps
1 DC blower - 450 CFM max. 200W, 24V to 53V so 4amps at 50V and 8amps at 25V
I'd like to just hook the blower directly to the panel, and let it blow whenever the sun is out. However I'm worried about the situation when the sun is blazing and I'm getting the full 265W (yes I have seen the panels perform at their rating), This will be too much watts for the blower. How can I provide full power to the blower, but dump excess amps to a diversion load?
Is there a way to setup a priority circuit where the blower gets the priority of amps, and then excess amps go to a second load? Almost like a relief valve in a hydraulic circuit.
All of this questioning is based on the assumption that if I have a panel in full sun but theres no load, or not enough load on it, then i'm damaging the panel. Am I correct?
