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.

Extensions with storage may qualify for state grants, and a bonus for storage systems is announced for 2027. We check what applies to your system.

Existing feed-in contracts with OeMAG or an electricity trader generally remain valid. An extension or module replacement can affect the terms, so we clarify this in advance with your buyer and the grid operator.

When a subsidised tariff ends you can switch to self-consumption with storage and sell the surplus at the OeMAG market price or to an electricity trader.

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 modules are recycled properly under Austrian rules for waste electrical equipment. We handle the process.

Businesses can claim an investment allowance for solar and storage. Please check the details with your tax adviser.

Yes, in many cases storage can be retrofitted. We check the inverter and meter cabinet and propose the right solution.
