Top Solar Companies in Italy 2026
Italy installed 6.8 GW of solar in 2024 — its highest ever annual figure — and aims to reach 80 GW by 2030. Strong southern irradiance, Superbonus tax deductions, and competitive electricity prices have made solar one of Italy's most economically attractive energy investments.
The Italian Solar Market in 2026
Italy's solar landscape is shaped by several key dynamics:
- Superbonus 70% (2026): The reformed Superbonus provides a 70% tax deduction on solar and energy renovation works, down from 110% but still one of Europe's most generous incentives.
- Comunità energetiche rinnovabili (CER): Italy's renewable energy community (REC) legislation enables collective self-consumption for homes and businesses within 1 km. Hundreds of RECs have formed since 2023.
- PNRR funding: Italy's National Recovery Plan allocated €59.5 billion in EU funds, with energy transition a key priority. Several billion euros are specifically targeted at solar and renewables.
- Mercato libero electricity: Italy's liberalised electricity market exposes consumers to high spot prices, making self-consumption economically very attractive.
Key Subsidies for Solar in Italy 2026
- Superbonus 70%: Available for energy renovation packages on primary residences and condominiums. Solar panels combined with heat pumps or insulation qualify.
- Detrazione IRPEF 50%: 50% income tax deduction for standalone solar panel installation on residential properties (spread over 10 years).
- Conto Energia replacement (Incentivi FER): New Incentivi FER 2 program provides operating incentives for renewable energy above a certain threshold — replaces the expired Conto Energia system.

How to Choose a Solar Company in Italy
When evaluating Italian solar installers, check:
- SOA certification (OG11 or OS4): Required for public contracts and larger private projects. For residential work, check for abilitazione professionale as an electrician or installer.
- Partita IVA & CCIAA registration: Every Italian company must be registered with the Chamber of Commerce (CCIAA). Verify at registroimprese.it.
- Gestore dei Servizi Energetici (GSE): Installers experienced with GSE registration procedures (for Scambio sul Posto and incentive applications) save time and ensure subsidy compliance.
- Assicurazione responsabilità civile: Ensure the installer has civil liability insurance covering the installation period and beyond.
