Is solar still worth it in 2026? Yes, but different from what many claim. We calculate your Pronovo one-off remuneration and the often forgotten tax leverage – honestly and neutrally for all 26 cantons.
No estimates. We use real geodata and current 2026 Pronovo rates for your roof.
We weed out the 'fortune seekers'. Only certified companies based in Switzerland receive your request.
You receive no aggressive sales calls, but solid quotes from verified pros in your region.
Many calculators only tell half the truth. The Pronovo one-off remuneration (approx. 20% of costs) is secure. But: The real financial leverage often lies in the tax deduction. As property maintenance, you can deduct the investment from taxable income – often more lucrative than any subsidy.
We only refer to certified Swiss solar professionals. No call centers, no sub-sub-contractors.
Yes and no. In the Midlands, winter yields are low (fog). Pro Tip: In the Alps or foothills (above the fog), solar power delivers peak values in winter. Those living in the lowlands need storage or a good summer strategy.
Beware of blanket statements. A battery massively increases self-consumption but often costs more than it saves in electricity. Rule of thumb: Batteries usually only pay off if installation costs are below CHF 800/kWh storage capacity.
Warning: Many payback calculations 'forget' the inverter replacement. Expect it to need replacing after 12-15 years (cost approx. CHF 2,000-3,000). Serious planning takes this into account.
The law accelerates large alpine systems. More important for homeowners: Feed-in tariffs for return delivery are tending to fall. Self-consumption will be more important than ever in 2026.
