Hi All; Thought I would share this for anyone thinking of purchasing solar panels this year. 180 watt panels assembled in America with as many US components as are available. $175 each ! They take offers. I paid $170 each . I bought 6 all together. 2 are in use & 4 are currently leaning against the wall waiting for a new project . When I can afford it I plan on purchasing a super insulated full size 12 vt chest deep freezer! Those 4 panels will be for it! Imagine... a stand alone deep freeze that lives at our house … not the neighbor's.I have been waiting many years to get a chest freezer at home !

Less than a dollar a watt, that is a deal! I already have 4 - 100 watt panels I got on sale from Amazon for $111 each. When I bought them it was the best deal I had found in months of watching. If I hadn't just ordered a bunch of stuff to build my own Powerwall from reclaimed and recycled parts I'd be trying to snag a few...
You got it! In the mean time, check out Jehu Garcia on YouTube. A lot of information on it there about reclaiming and using lithium batteries. I ran across him in my research on if it could be done. Yes, yes it can.
That ebay ad lists 17.0 % efficiency. Is that good? I honestly haven't done my homework, and have no brain RAM to do it now. If I buy one of these it will be just to stock it so later when I have time/space/etc I have a panel that was a good choice, already here. I am assuming Thomas makes good choices :) Just curious about that number.
That eBay ad lists 17.0 % efficiency. Is that good?
Yes, I believe that is a good efficiency rating if it's achieved. My panels are rated at 15.4% From what I've researched it seems like anything over 15% is good, 20% is close to the upper limit. I've seen claims of 22%, but I have to believe that is ideal lab conditions.

With the right type charge controller you can use them in a 48 volt system. My main system is 48 volts. It's being fed by two different sets of panels, one set is 12 volt panels connected together into 2 series of 5 and the other set is 24 volt panels connected together in 5 series of 2. Each set has it's own MPPT charge controller due to the different voltages. They work in tandem to charge the 48 volt battery bank.
Yes my current 48 volt panels are hooked up in series as well as they don't actually put out 48 volts as they say but at that point if I need five of them I might as well just buy full size 48v solar panel is they would not only match the current ones but it's easier to mount one and cheaper then to mount five
