Solar System

Clean and cheap electricity directly from the sun

Your climate-neutral journey starts with a solar system.

Installing solar panels in your home enables you to reduce your power bills and secure inflation-free energy costs for over 30 years.

We have solar systems that suit any home, no matter what your energy needs or goals are. Our 1KOMMA5° solar panel is developed and produced sustainably using raw materials from Germany, ensuring you get high-quality, reliability and value for money.

Battery Storage

Store energy by day, use at night

Solar panels generate electricity when the sun is up. Your home uses some of this energy and can sell the excess power back to the grid at the prevailing feed-in tariff.

However, at night, power companies may charge you up to ten times the amount they paid for your excess energy. By installing a battery storage system, like the Enphase IQ Battery, Tesla Powerwall or SolarEdge Home Battery, you can store the free energy collected from the sun during the day and use it at night, reducing your reliance on expensive grid power.
