Every kWh guarantee is covered by an insurance policy from a Lloyd’s of London syndicate and issued by an independent foundation. This structure is designed to give you security independent of Autarco.


Your solar system's objective is to produce power that you can use in your home or business. If an Autarco solution produces less useable power than guaranteed you receive the difference in cash.


Unlike solar panel component based performance guarantees, Autarco’s kWh guarantee does not require any laboratory testing. The output displayed in MyAutarco is what determines any claim.

Solar energy with peace of mind

Your Autarco system comes with a kWh guarantee: an energy performance guarantee measured in kilowatthours. If your Autarco solar PV systems generates less than what was guaranteed, you get your money back at a fixed rate per missed kWh. It really is that simple.

Your installer uses Autarco software to accurately analyse your roof and model the expected performance based on the system design, your location, roof details and precise shade profile.

After installation Autarco will complete a technical due diligence and issue one or more kWh guarantee certificates, each covering a period of 5 years. Every kWh guarantee is underwritten by Lloyd’s of London.

With Autarco you and your installer enjoy the peace of mind of knowing that your investment in solar is protected and you have chosen a brand that respects the contribution to the energy transition you have both made with your time and money.

How is it possible?

Autarco is a technology company. In order to provide the industry’s first and revolutionairy insured kWh guarantee we have had to develop new technologies and develop a long track record of reliable system performance.

Besides developing state-of-the-art solar PV technology such as our high efficiency modules and extremely reliable solar inverters we had to bring together leading scientists and their latest research results in the fields of meteorology, machine learning, climate modelling, building physics, etcetera.

Fundamentally Autarco removes all uncertainty and streamlines what goes onto your roof. Because we know exactly what is installed how and where, we can integrate  our products’ component warranties into the kWh guarantee.

After issuing the kWh guarantee, we remain a stakeholder by actively monitor the performance of your system and bring utility grade asset management practices to the rooftop segment. Should a system underperform we know it before you do and take appropriate action.

The Autarco kWh guarantee is insured by Lloyd’s of London, the leading insurance company. Your investment is secure at all times and every kWh guarantee is totally prepaid and covered by the insurance for the whole term.
