I have two hot water solar panels, they are made by Radco products Inc, Model 408P-HP and have a 32.28 Sq. Ft. of surface area each (46 x 101.5 inches). They are about 15 years old. The sealing caulk for the glass is dried up, but it appears I could remove the the tops of them easily enough clean and reseal them with new caulk. Any thoughts. I was hoping they be worth about $400 each, sicne new panels are well over $1,000.

A couple of these on Craigslist for $300 http://southjersey.craigslist.org/mat/775999790.html I've been buying panels and watching prices. Basically, they seem to go from about $150 to about $400. This doesn't seem to depend as much on the quality as on the availability (which these had been available when I bought mine). You might try pressure testing them, since used panels are always a risky purchase if you don't know if they leak. You might also explain what you've run through them since I hear that glycol will degrade the panels. Removing and re-caulking the glazing is not difficult, but it is long and tedious.

Yes that was my ad. :) I had some interest, but no buyers, A typical panel contains 26 pounds of copper and about 80 pounds of aluminum, I got $75 each from them at the scrap yard after I seperated the components. I have the Glass and insulated panels left, I plan to use the insulation in the basement, leaving only the glass to dispose of. 4 sheets of Free glass, anyone interested? :)

What's wrong with the folks in New Jersey that the don't want solar panels? The glass should sell on CraigsList - it's probably tempered, someone must have a solar project in mind. Or maybe you could build one of these Solar Air Heater with it.
