Used and resold solar module pricing aligns with general market


EnergyBin, a website for selling solar hardware, has released their second annual PV Module Price Index for the Secondary Solar Market. The index tracks the price of new and used solar modules listed for sale.

EnergyBin does not take commissions on module sales or track actual final sales, so their data tracks listed prices only, not actual sales. The group lists solar components from over 500 companies that have registered on their website. From January 2020 to December 2022, the website listed 3.6 million modules with a total capacity of 1.35 GW.

Since January 2020, solar module prices on EnergyBin have increased across all classes. Prices increased until January 2022, held near that peak for around six months, and then steadily decreased throughout the rest of the year.

Solar module pricing has not returned to the lows seen in 2020 and early 2021. And due to growing demand, U.S. import challenges, and polysilicon shortages, module prices mirrored those seen in the general marketplace in 2021 and 2022.

Starting with the middle 2021 polysilicon shortages due to factory fires, then buoyed by major growth, polysilicon prices increased by over 200%. This broke the decade-long price decrease streak of solar modules. Amongst the many advances in that period, the effective price per watt of polysilicon fell by 96%. Later in 2022, aligned with the EnergyBin price decrease, we started to see the price of polysilicon also begin to fall – before bottoming out in January. It is projected we will see further solar panel price relief, due to massive industry scaling going forward.

EnergyBin has found that the volume of available modules tends to peak during the first and fourth quarters of the year, and decreases in the second and third quarters.

BayWa r.e., GoodFaith Energy and Inovateus Solar are a few EnergyBin users listed on its website.

Price per watt ($/W) of solar panels

In 2022, used solar panels represented approximately 9% of all modules listed on EnergyBin’s website, and prices fluctuated from $0.095/W to $0.197/W. EnergyBin observed that at one point during the year, a single project contributed a 27.5 MW volume of used modules, which increased the percentage of used solar modules on the website from 4% to 9%.

EnergyBin says that used modules cost 50% to 80% of what new products cost. Some of the larger solar distributors and re-distributors can be found on the website, along with local shops stocking smaller quantities.
