Solar panels come in a range of sizes.

How many solar panels to run a window ac unit.

I decided to stress test my solar panel system by turning the portable ac unit on high and setting the thermostat to 60 degrees. Ballpark 800 to 1000 amp hours of battery and 1500 watts of solar would be a starting point. For example a portable ac like the honeywell 10000 btu only requires 880 watts. With 325 wp solar module no.

The higher number of watts per panel the less of them you ll need to generate your full electricity needs. Hence 1 625 kwp system would be required with 5 nos. There are solar generators that will run some ac units. Of 325 wp to run 5 stars 1 ton ac.

This number will be the number of solar panels necessary to cover your air conditioning needs. So smaller portable air conditioners or window units would be able to run on the yeti power station we looked at above. Stress testing my portable ac unit and solar panel power system. The first 500 watts produced go to the air conditioner directly.

In seattle you d need a 4 75 kw installation about 18 panels. To provide about 14 5 kwh of electricity each day in arizona you d need a 3kw solar installation or a system with about 12 solar panels. Assuming that the air conditioning unit requires 1500 waats of power a collection of 6 solar panels at 250 waats capacity could in theory power the air conditioning unit but a lot of individual factors can throw this number in either direction. Most on the market today are between 250 365 w.

A single solar panel is going to charge your batteries much too slowly you ll use up the stored electricity faster than the solar panel can charge them again. For the above ac requirement a 1 4 kw on grid system is required as per thumb rule 4 units are generated from 1 kwp in a day. Where you are and what tempetature and humidity you want can require double or half that. Of modules will be 1 4 0 325 4 307 5 nos round up.
