2025 PV Module Price Index

Secondary Solar Market

The PV Module Price Index is presented by EnergyBin, LLC. and Buckstop, Inc. to provide the solar industry with historical crystalline-silicon (c-Si) module valuation within the secondary market.

All prices are represented as wholesale values and are taken from trade activity on the EnergyBin wholesale exchange. Modules assessed in this index were listed for resale and available for immediate delivery from a U.S. location in 2025.

When reading the price index, consider that findings are based on modules traded within the secondary market, and therefore, the following applies:

• The price per watt (PPW) is based on spot prices of c-Si modules listed for resale on the EnergyBin wholesale exchange.
• The PPW is represented as the weighted average per module class for a given timeframe.
• Prices are quoted by resellers for the U.S. market.
• Because these goods are already located within the U.S. market, no additional import duty would be assessed, as they are treated as domestic trade goods within the secondary market.

Modules assessed for the price index were taken from resale listings posted to EnergyBin from 2020 through 2025. This index represents a sample of 2,800 listings comprising 8.7 million modules and classified into categories of All Black, Bifacial, Monofacial, Legacy POLY, and Used. Resale listings ranged in quantity from 1 to 300,000 modules with an average quantity of 3,000.
