If YOU had 9 of these solar panels with no controllers what would you do with them?
I bought 9 solar panels at a discount price because they were returned because the controllers were bad. Panels are rated 12 VDC 15 watts each. The no load voltage is about 17 volts.
So far I have no good ideas that would be worth the effort. All 9 in series will light up a light bulb. All 9 in parallel connected to a 150 watt DC to AC inverter will light up a light bulb. That is about all it will do with no storage battery.
I am picking every ones brain. Need some ideas?
Notice the picture shows 3 panels and I have 9 panels.
