Solar Comparison by Country
Europe 2026

Analyze European solar markets: installed capacity, costs, productivity, support mechanisms and investment potential by country. Complete guide for investors, developers and prosumers.

Why compare solar markets?

The capacity and profitability of solar installations vary significantly across European countries. Differences in production costs (LCOE), residential electricity prices, annual productivity and support mechanisms create distinct opportunities and risks for each market.

This interactive comparison allows investors, project developers and prosumers to quickly identify the most attractive markets based on their criteria: profitability, growth potential, regulatory stability and return on investment.

LCOE Comparison (Levelized Cost)

Lower = more competitive. Average values in €/MWh

LCOE (Levelized Cost of Energy) represents the average cost of electricity production over the lifetime of an installation. Countries with the lowest LCOE (Spain, Portugal) offer the best economic competitiveness for utility-scale projects.

Detailed Country Profiles

🇫🇷 France

▼

Market Context

France has the 3rd largest installed capacity in Europe (31 GW in 2025). The French market is in steady growth with 5.9 GW added in 2025. The national target for 2030 is ambitious (54–59 GW), supported by the post-nuclear energy context and emission reduction expectations.

Key Regulations

  • Calls for Tenders (CfT): Main mechanism for utility-scale, regularly launched by CRE
  • Self-Consumption: Regulated by decrees since 2017, simplified grant
  • Access Criteria: Preferences for building-mounted and existing rooftop projects
  • Residential Feed-in Tariff: Revised quarterly, currently ~0.25 €/kWh

Support Mechanism Details

Calls for Tenders: Competitive selection for large projects (> 500 kWp). Recent tariffs: 45–55 €/MWh (2025).
Self-Consumption Grant: Investment aid degressive (0.30–0.60 €/Wp by technology).
MaPrimeRénov': Residential subsidy (eligibility by income).

Opportunities

  • Favorable energy context (energy independence)
  • Dynamic residential and self-consumption market
  • Regulatory stability and predictability
