These suntechs from santan are awesome. I don't know if it's the best watt per dollar but it has to be close.
They're specced for 285W but managed 275W. From what I've seen on maps the solar irradiance for north Ga isn't that great, but it is a cool day, so I'd say it's a wash. Either way I think they did great for cheap 9 year old panels.
Bad thing is that they're heavy. 60lbs each. Unloading them by myself wasn't fun. But I threw together a quick test and ended up surprising myself. I'm also surprised that horrible connection on the battery was flowing 19amps without getting warm
So they're $80 on the site, but $63 on ebay. I called them up and they rang them up for $60. I also added 100ft of wire and some connectors and shipping for everything was $230 to the local terminal. A few days later I had a box from UPS and 10 days later the panels were here for pickup.
Voc on all of them was around 43.8 and operating temp was 128f. Unconnected panel was at 138f
