How much does it cost to install photovoltaic modules

Current photovoltaic module prices range from approximately €0.25 per watt to €150 per kWp, depending on technology and module type.

Current Price Overview

As of 2026, monocrystalline PV modules, particularly glass-glass or bifacial types, are the most common and cost-effective options. Prices for these modules are generally around €150 per kilowatt-peak (kWp) for glass-glass modules, while high-performance modules with over 400 Wp can cost €100 to €200 per piece . For a typical 10 kWp residential system, the module costs alone would be roughly €2,000 to €2,500 . Lower-cost modules, such as standard monocrystalline glass-film types, may be available at €0.25 per watt, translating to about €90–110 for a 420 W module . Prices for polycrystalline or thin-film modules are generally higher or less common in 2026.

Factors Affecting Module Prices

1. Technology Type: Monocrystalline modules are cheaper and more efficient than polycrystalline or thin-film modules. Bifacial and glass-glass modules offer higher durability and energy yield but can be slightly more expensive .
2. Manufacturer and Origin: Non-Chinese manufacturers often charge more but may provide specialized formats, higher efficiency under low light, or longer warranties .
3. Market Trends: Prices have been influenced by technological advancements, mass production, and global overcapacity, though geopolitical factors and raw material costs (e.g., silver) may increase prices in 2026–2027 .
4. Purchase Volume: Wholesale or bulk purchases can reduce per-module costs, but end-customer prices for rooftop installations are higher than spot market prices .

Residential Installation Example

For a 4 kWp DIY residential system using 10 modules of 400 Wp each:

• Module cost: €1,000–€2,000
• Inverter cost: €800–€2,000 depending on type and features
• Total system cost: Modules typically account for 30–40% of total investment .

Summary

• Average module price: €0.25 per watt to €150 per kWp
• High-performance modules: €100–200 per module (400+ Wp)
• Residential 10 kWp system: €2,000–2,500 for modules alone
• Factors influencing price: technology, manufacturer, market trends, and purchase volume Investing in modern PV modules is generally recommended now due to immediate energy savings and available subsidies, even if future price reductions are possible .
