How much do photovoltaic power generation modules cost

The cost of photovoltaic modules in 2026 ranges from approximately €0.06/Wp for low-cost modules to €0.145/Wp for high-efficiency or full-black modules, with typical residential modules costing €65–€81 per square meter depending on wattage.

Cost by Module Type

• High-efficiency modules: Around €0.130 per watt-peak (Wp), reflecting a 13% increase from early 2026 prices .
• Full black modules: Approximately €0.145/Wp, up 11.5% month-on-month .
• Mainstream modules: About €0.115/Wp, showing a 9.5% increase compared with the previous month .
• Low-cost modules: Around €0.060/Wp, slightly down compared with 2025 but up 9.1% from January 2026 .

Cost per Square Meter

Residential PV modules are often priced per square meter, with costs varying by wattage:

• 300 W modules: ~€81/m²
• 400 W modules: ~€74/m²
• 500 W modules: ~€65/m² Higher wattage modules require less area per kWp, which reduces the cost per square meter but may increase the price per module . For example, a 50 m² roof would require modules costing roughly €3,700, while a 100 m² installation could cost around €7,400, depending on module type and efficiency . PV modules typically account for 30–50% of the total system cost, making them the largest single cost factor in a solar installation .

Regional and Market Considerations

• European markets: Module prices generally range from €0.095–€0.110/W, influenced by trade policies and supply agreements .
• US markets: Higher prices, around $0.25–$0.28/W, due to tariffs and domestic content requirements .
• Chinese FOB prices: Among the lowest globally, approximately $0.087/W .

Summary

The cost of photovoltaic modules depends on efficiency, wattage, technology, and regional market conditions. For residential installations, expect €65–€81 per square meter, while wholesale prices per watt range from €0.06 to €0.145/Wp. These prices are a key determinant of the overall cost of a PV system, which also includes inverters, mounting, and installation.
