Our modular energy system lets you harness the power of the sun to produce your own electricity. You’ll be conserving natural resources and making an important contribution to a better environment.
Since 1 January 2023, in addition to physical feed-in, we offer the option of selling the environmental added value of your solar power to ewz as a guarantee of origin.

In many cantons, you can deduct the cost of installing solar panels on existing buildings. The investment cost can also be carried forward to the next two tax periods if it hasn’t been possible to take these expenses fully into account for tax purposes in the year in which they were incurred. We recommend that you clarify the details with your tax office.
If you move away, you can invoke your take-back guarantee. We’ll then buy back your share of electricity. Alternatively, you can transfer your solar power supply to another customer. Let us know about your move, then we’ll discuss with you what you need to do.
Use our solar panel calculator (in German) to find out whether the roof of your building is suitable for a solar power/photovoltaic system.
