Solar panel insurance in Germany: rooftop systems, batteries and balcony solar

Named perils versus all risks

A German buildings policy only pays when one of its listed perils strikes. Many common solar losses fall outside that list: a surge that is not caused by a direct lightning strike, a short circuit in the inverter, martens gnawing cables under the panels, snow load, stolen modules, damage during cleaning.

Dedicated solar policies are usually written on an all-risks basis. Anything sudden and unforeseen is covered unless it is expressly excluded. That shifts the burden of argument in your favour, which is the real value of the product.

Balcony solar in a rented flat

Since Germany's Solarpaket I, plug-in solar devices with up to 800 W inverter output and 2,000 W of panels benefit from simplified rules. They must be registered with the Federal Network Agency's market master data register (Marktstammdatenregister). Since late 2023 the model contents conditions of the German insurers' association treat them as household contents if they are not permanently fixed to the building.

Since October 2024, tenants have a statutory claim under § 554 of the Civil Code (BGB) to their landlord's permission for such a device, which the landlord can only refuse if it is unreasonable. If a panel falls and damages a car below, your personal liability policy is the one that pays.

Lost income, batteries and the rest of the system

If the inverter fails in May and a replacement takes six weeks, you lose production in the best weeks of the year and buy more expensive grid electricity. Good solar policies pay a daily amount for downtime, either a flat rate per kilowatt peak or based on proven yield.

Home batteries are often a large part of the investment and sit in the basement or garage. Make sure the policy names the battery and its value. Some policies also include the wallbox and heat pump, which avoids disputes about where the solar system ends and the building begins.
