Co-financing of solar power plants in 2026

This year brings exceptional opportunities for co-financing solar power plants for family homes.

On one hand, starting from January 1, a new electricity billing model comes into effect, the so-called net billing, which makes feeding surplus energy into the grid less profitable than before. On the other hand, right now numerous public calls are open that enable co-financing of up to 50%, or even more if you combine local and EU incentives. In this article, we will thoroughly review all active tenders, explain the technical conditions, and show how you can make the most of this year to achieve energy independence for your family.

Why is 2026 a favorable year for solar power plants?

Instead of the previous net metering, where you "loaned" surplus energy to the grid for free, you will now pay full network charges and fees on the energy fed in. This means that the payback period for the investment will be extended for those who do not optimize self-consumption. However, precisely because of this, the Environmental Protection and Energy Efficiency Fund (FZOEU) is planning a new large call in the second quarter of 2026 with an emphasis on battery systems.

If you prepare the documentation in the spring period through local calls, you can be ready as soon as the national tender opens and achieve a combination of incentives that is rarely seen.

How to make the most of this co-financing for solar power plants?

Some public calls allow retroactive co-financing, i.e., reimbursement of funds for solar power plants installed and commissioned in 2024 and 2025. If you installed your power plant during that period and have not yet used the incentive, check the current or upcoming calls. Retroactive applications are often possible up to a certain period after commissioning. This means that even those who invested before the electricity billing changes can receive a significant return and shorten the investment payback period.

If you are considering solar power plants, the first step is to prepare the main electrical project – this is the key document that opens the door to all calls. At Duplico, we offer complete "turnkey" solutions, from design to commissioning, with a guarantee that everything will be fully compliant with HEP's conditions and technical specifications.

With active local tenders and the upcoming national call, you have the opportunity to reduce your electricity bills by 70-90% and contribute to the green transition. Don't miss out on the funds – contact us today and together we will prepare your project.
