"With the kWh guarantee we warrant the performance of your entire PV system after install, not just the performance of the solar panels under laboratory conditions."

Roel van den Berg - CEO


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 solar panels and extremely reliable 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.

The kWh guarantee covers you against underperformance due to product defects, installation defects and low solar insolation.

A kWh guarantee covers performance of an Autarco PV system for a five (5) year term and is embodied by a kWh guarantee certificate. You can get up to 3 consecutive kWh guarantees so your solar PV investment is protected for up to 15 years.

At the end of each five year term we check the guaranteed value on the certificate with the actual performance of the PV system as measured by the inverter or MID approved meter. In case of underperformance the beneficiary of the kWh guarantee receives the compensation rate per missed kWh.

In cash. So your business case and bottom line are protected!

Yes. The compensation rate is flexible to meet your economic reality and can be set at 5, 10, 15 or 20 eurocents/kWh.

The terms are very simple. The most important obligations on the beneficiary of the kWh guarantee are:

  1. Ensure that the monitoring devices are connected to the internet so that they can communicate their status and performance to the servers.
  2. Act upon instructions to clean or otherwise perform maintenance on  the solar PV system.
  3. Grant acces to the PV system for inspection, maintenance or modification should this be requested.

After installation your installer registers your system with Autarco. A very thorough technical due dilligence is then undertaken to check whether the installation is done correctly and the system is performing as expected. If the registration passes this verification step, the requested kWh guarantees are issued.

The kWh guarantees are issued by an independent foundation. Using this foundation, with an independent board comprised of industry experts, ensures that every guarantee can be honoured no matter the trading status of Autarco.

The foundation engages in consecutive insurance policies each with prepaid risk limit. When kWh guarantees are issued, the guaranteed value is deducted from the risk limit. When the entire risk limit of a policy is used up, a new insurance policy is engaged in and Lloyd’s of London will issue a confirmation stating which kWh guarantees are endorsed on the filled policy.

Autarco transfers funds to the foundation for each system that passes the technical due dilligence and verification phase. The foundation uses those funds to pay for insurance premiums as the policy holder and beneficiary of the Lloyd’s of London insurance. All premiums are prepaid such that there is never a kWh guarantee issued without available risk limit on a policy.

Each kWh guarantee is issued from the independent foundation, covered by a Lloyd’s of London policy for the full term and all insurance premiums are prepaid. Coverage is therefore not contingent on annual premium payments nor is the trading status of Autarco relevant to the ability to claim on the insurance.
