Repowering

Repowering upgrades your existing PV system with modern components to increase performance, efficiency, and lifespan.

Repowering is worthwhile when your system is over 10–15 years old, showing reduced output, or when modern technology can significantly boost performance on the same area.

Typically solar modules, inverters, and cabling are replaced. The mounting structure can often be retained if it is still in good condition.

In most cases, yes. Older inverters are often incompatible with modern, higher-output modules and lack current efficiency standards.

Often yes, provided it is structurally sound and compatible with the new modules. Our experts will assess this during the on-site inspection.

Repowering can be combined with heat pump integration and EV charging solutions to maximize your self-consumption and overall energy efficiency.

We start with an on-site assessment, design the optimal upgrade, handle all permits and installation, and ensure everything is commissioned and monitored.

Costs depend on system size and components replaced. Thanks to higher yields and current subsidies, payback periods are typically 8–12 years.

Yes, building permits and grid connection regulations may apply. We handle all regulatory requirements as part of our service.

Yes, repowering projects can qualify for federal and cantonal subsidies. We help you identify and apply for all available funding.

Existing KEV contracts remain valid. However, repowering may affect the terms, so careful planning is essential to preserve your feed-in tariff.

After KEV expiry, you can switch to self-consumption optimization or negotiate a new feed-in tariff with your energy provider.

Repowering may change your feed-in tariff conditions. We advise on the best strategy to maximize your returns.

The best time is when your system's output has noticeably declined, components are reaching end-of-life, or when subsidies make the investment attractive.

Absolutely. Modern modules produce more power, and combined with battery storage, you can significantly increase your self-consumption rate.

Yes, we offer repowering for all existing solar systems regardless of the original installer.

Old panels are professionally recycled in accordance with Swiss regulations. We handle the complete disposal process.

Yes, repowering investments are generally tax-deductible in Switzerland as energy-saving renovation measures.

Yes, in many cases we can integrate your existing system into a SolarFree model, combining repowering with our all-inclusive service.
