Frequently asked questions

Can you deduct the investment cost of your solar panel installation from your taxable income?

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.

You’ve invested in an ewz.solarzüri solar power plant. What should you do if you’re moving away from Zurich?

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.

How can you check whether your property is suitable for a solar panel installation? And what will it cost?

Use our solar panel calculator (in German) to find out whether the roof of your building is suitable for a solar power/photovoltaic system.
