Solar Panels

Used solar panels

Used solar panels are usually a great bargain. Unless there is obvious major damage, you are most likely making a very safe and thrifty purchase–and if you can test the panels with a multimeter in full sunlight before purchase, you are almost guaranteed a functional panel.

Nobody really knows what the lifespan of a solar panel is, since many of the very first panels are still in operation.  Newer panels pack more wattage into less space. If you don’t have to worry about space, older used panels will almost always be your best deal for “dollars per watt.”

Avoid panels with obvious damage, unless you are willing to dig in there and fix them. Cracked glass, condensation under the glass, and broken connections are common problems, but can sometimes be fixed. Used solar panels can be a great bargain for property owners who are interested in adding a low cost means of generating green electricity for their home.
