How much does a photovoltaic panel cost?
Mainstream Photovoltaic Panels: Average price of €0.10/Wp, down 9.1% month-on-month. Low-Cost Photovoltaic Modules: Average price of €0.060/Wp, a decrease of 7.7% compared to the previous month. These figures underscore the significant pressures in the photovoltaic market, as price reductions strain margins to unprecedented levels.
How much does a photovoltaic module cost?
Mainstream Modules: Average price of €0.11/Wp, stable compared to September but 21.4% lower than January 2024. Low-Cost Modules: Average price of €0.065/Wp, a 7.1% decrease from September and 27.8% from January 2024. These trends are exerting mounting pressure on the photovoltaic sector.
Are low-cost photovoltaic modules escaping the price war?
The company recorded price reductions of around 4%, with only low-cost photovoltaic modules escaping the trend. Specifically, in August 2025, the Price Index showed: about €0.055/Wp for low-cost photovoltaic modules, unchanged from July prices. “Manufacturers are moving quickly to end the devastating price war.
Where did photovoltaic cost data come from?
Photovoltaic cost data between 1975 and 2003 has been taken from Nemet (2009), between 2004 and 2009 from Farmer & Lafond (2016), and since 2010 from IRENA. Prices from Nemet (2009) and Farmer & Lafond (2016) have been converted to 2024 US$ using the US GDP deflator, to account for the effects of inflation.
