Large solar panels

I'm going to do a residential as soon as my solar & battery bank is done. I'm not liking my dometic. I'm looking at doing 3 320w panels.

See signature. Would not change a thing. Prices are even lower today.

I run a 250 W 24 volt panel and love it. It was 5x3 ft but it fit well on the roof. I run an MPPT charge controller and it works well. I have seen 12 amps out of it but it's capable of 17. I don't tilt so I don't expect more than 12 amps. It's simply a case of space. If you can fit the bit one, do it. If not, go with smaller ones to fit to your roof.

This was my first stab at solar and I did considered large panels at first but after mocking it up with cardboard I decided on 12 volt 58" x 26" panels end to end on the curb side. Bigger panels were cheaper per watt but in the end I dont think I could have gotten as many amps up there as I can now. Or I may have gotten more but not had as easy access. I'm considering a residential frig but haven't researched it enough yet so I may add another string on the street side with pretty clear access down the center. There is enough room to step between the panels and ac or vents. No stepping over anything and I'm not walking near the edge.



While out west last winter with only 520 watts I had to tilt so small or large panel they would need to be tilted. When the wind was blowing dirt so thick that we couldn't see a half mile away and the rig was rocking I would have been worried about a big panel. I dont want to tilt or even go up there so I left them up for 2 1/2 months.
