Small solar system for swamp cooler
Hi All, a complete Solar neophyte. We live out in the boonies and grid power is expensive at around $0.30/kWh. Winter bills are fine but Summer with the swamp cooler going 12-hours a day it almost doubles our monthly bill. It has a 1/3hp pump and 1/15hp circulation pump, all 110vac. Both pumps cycle on and off together, about 20-minutes on and 15 minutes off for about 12-hours. Nights are cool enough to not need it and plenty of sun all day.
I have it all controlled by Arduino's on our home Iot-network I designed, programmed and and built. I am wondering if I could get a car battery (or two) and one of the low cost 12v 100W solar systems for the swamp and maybe add another panel if needed. I could also run a battery charger off the grid overnight if it made sense to do so. I might even make a dual-axis tracker for the panels as I have some old Satellite dish positioners.
We are using rain collected water for the swamp instead of the 600-ft well pump water, and solar power would be a nice addition for free cooling.What's the minimum equipment it would take to do this. I do not want to buy one of the solar-kits as they seem to include stuff I don't need like clips and cables, relays, terminal blocks etc, all well within my skill set to manage. I already have an 800/1200 Watt (run/peak) inverter, I rediscovered it in a shed yesterday and it got me thinking.
Thanks for reading this far.
