What would my options be for purchasing solar setup for 1 purpose a well pump that's a little less than 1hp
Approx cost?
How many panels and what size panels would I need.
The well pump is most likely 3/4hp but there is a chance it is 1hp. I think it is 240v 30amp circuit
I've been thinking the same thing for last few weeks
how much water flow do you need? ie gallons that will be driving energy storage requirement directly for battery.
local? and how much sun?
i will use one hour run in calcs so you can scale.
i was assuming 2hp for margin in my case it will be deep like 500 plus ft well
simple pressure switch takes no power.
it will need to be 240V ac
need inverter for 240V ac, and its efficiency and loss
battery bank voltage, lets assume 48Vdc
lets say for conversion purposes/power flow 2000w invertor for the 2 HP.
this is 42 amps. and of course energy storage would be needed is 2000kw/h for each hour of run without sun.
need a battery that can supply 42amps constant, close to 50ah, this would be (4) 12v50ah batteries in series.
lets assume standard deep cycle battery is 100amp hour, so 4 of these batteries would run you for 1hr and drain from 100% to 50%
that would get you many thousands of cycles to 50%. never go to zero
PV size. winter or summer??
lets assume winter clear day with 2 hours of real sun equivalent. so you would need to charge 2000w in 2 hrs so 1000w of PV panel for a worse case dead battery recharge. or 500w panel system just for the 1hr pump run winter to recharge for 50%
for winter use panels will need to be mounted almost vertical for max sun.
summer
