List,

Once again I am working on my small solar backup project. It will be a 12v system with 220Ah of capacity.

Recently I came across a fellow selling used ASE Americas 300w panels with these specs:

Pp= 300
Voc= 20.0 dc
Vp= 17.2 dc
Isc= 19.1 dc
Ip = 17.4 dc

I am thinking one panel would work to provide the power I need using a MS SunSaver 20A PWM charge controller.

Question: These specs are of a 12v panel that would meet my needs, right?

Just want to make sure before taking the plunge.

Thanks for the advice.

    That panel would certainly keep the batteries charged in case they were needed for backup. Everything else depends on what you're backing up and for how long. Yes, they are 12v panels.

    what type of battery do you have, it looks like you will get about a 10% CHARGE RATE, so you want to check what the battery will take..
    what is the $ / WATT FOR THE PANELS?
