Just as if you were selling a used appliance or hot water heater, you will likely sell the panels at a reduced cost. Some companies specialize in purchasing used PV panels, or you can advertise your panels and accept the best honor. Their worth will depend on how much power they continue to generate and their general condition.

I’ve put them in order of least to most costly, although the final option may not be expensive for those with a convenient place to shove them: Sell them. Give them away. Live where the local Council will take them. Find a scrap dealer who will take them for free. Pay for them to be disposed of as electronic waste. Pay for them to be recycled.

Wholesale solar companies have two main options for selling excess, surplus, clearance, and used PV equipment in the secondary market. They can utilize auction sites, and they can join EnergyBin, the wholesale solar B2B exchange for the world’s PV professionals.
