Overview of Solar System Subsidies in Switzerland
Switzerland has a three-tier subsidy model that includes federal, cantonal, and municipal levels. The combination of these levels significantly reduces investment costs and accelerates the amortization of solar systems. In 2026, stable subsidy rates and new legal regulations, such as minimum compensation for supply, offer great advantages for investors.
Pronovo AG manages federal subsidies, while cantonal authorities run specific programs for technologies like battery storage. Local providers often offer additional bonuses.
- Pronovo AG is responsible for federal subsidies.
- Cantonal subsidies vary by zone.
- Additional bonuses from local energy providers possible.
National Subsidy: The One-Time Remuneration (EIV) via Pronovo
To receive the grant, the complete documents must be submitted after commissioning. The clear process requires precision and experience.
- Technical documentation by the specialist company.
- Certification takes place after grid connection.
- Submit application via Pronovo customer portal.
The EIV provides a solid base for financing solar systems.
Cantonal Differences: Where Extra Funds Are Available
Cantonal subsidies often complement federal benefits and offer additional incentives for energy storage and energy efficiency measures. Strategies vary greatly among the cantons.
Special programs for battery storage aim at self-sufficiency and grid stability. Local subsidies from municipalities and energy providers often add the “icing on the cake” to financing strategies.
Tax Deduction and Indirect Subsidy in Switzerland
Investments in photovoltaics, considered maintenance costs, can be tax-deductible. Recipients must, however, consider federal and cantonal subsidies.
A targeted tax deduction can extend over several years, which is optimal for tax purposes.
- Tax deductions effectively break progression.
- Self-consumption increases the financial impact of the system in the long term.
Proper tax deduction reduces operating costs in the long run.
