How many solar panels

[RidgeTopWVA]

How many solar panels would it take to run a window air conditioner ?

Will Prowse and CheapRV Living have a couple of youtube videos on this. Depends on the size of the window unit and how much start up power is required. The solar panels are relatively cheap. The storage batteries aren't.

Maybe only one of you have a big enough battery and you don’t want to run it often. If you mean how many will it take to run the AC directly from the panels, that’s almost impossible. Each panel only produces about .5 volts with varying watts depending on the size of panel. Really hard to get the power you need without a battery (bank) as ACs have pretty significant starting draws and are fairly power hungry in general.

0.5V??

Panels on my shop at 44VDC open circuit, 37VDC loaded.

Each string coming into inverter is ~ 530VDC open, 450VDC loaded

Key word, panels. What is the cell voltage in your panels? It’s going to be between .5v and .6v. 37vdc is a sum of the output from the number of cells and number of panels. You obviously invested a lot in the system, so you probably understand this.

It doesnt sound feasible.

You wrote 'panel' in your initial reply, instead of cells. Thats where the confusion came in.

its actually been done for years... rv people do it all the time

it doesn't matter, he's wasting people's time with his antics. no one gives a crap about cell voltage, as its completely irrelevant.

Grrrr, that's why you can't trust anything on the internet. Sometimes I iz we Todd did.
