A milestone for the energy transitionโand new rules for solar system operators. We provide you with important information about the Solar Peak Act!
The new Solar Peak Act has been in force since February 25, 2025, bringing with it a number of changes for households with PV systems.ย
The official name of the Solar Peak Act is "Act Amending Energy Industry Law to Avoid Temporary Generation Surpluses." It sounds cumbersome, but it is a crucial step toward making our power grid fit for the future.ย

More informationWhy is the Solar Energy Act necessary at all?
Germany has surpassed the milestone of over 100 gigawatts of installed photovoltaic capacity โ a tremendous achievement! However, this boom also presents a challenge: on sunny days, more electricity is often generated than consumed. The result? Negative electricity prices and grid overload.ย
The Solar Peak Act is intended to address precisely this issue: it creates new rules to avoid generation peaks and stabilize the grid.ย

The most important changes at a glance
1. No compensation for negative electricity prices
New PV systems commissioned on or after February 25, 2025, will no longer receive EEG remuneration if the exchange electricity price is negative. Although this only affects a few hours per year, it sends a clear signal: electricity should be used or stored when it is generated.
๐กโฏGood to know:โฏThe lost subsidy will be made up for at the end of the 20-year termโprovided that a smart metering system is installed.
2. Feed-in limitation without control technology
Anyone operating a new system without a smart meter or control box may only feed 60% of the installed capacity into the grid. This is intended to prevent grid overloads in the short term.ย
๐กโฏTip: With an energy management system (EMS) such as our Leaflet HEMS, you can cleverly circumvent this limitation by using or storing the electricity yourself.
3. Controllability becomes mandatory
New systems above 7 kWp must be remotely controllable in the future. This means that smart meters and control boxes are mandatory. This controllability is checked regularly.

What does this mean for you as a plant operator?ย
With a modern energy management system, you can not only meet the new requirements, but also benefit economically:ย
- Optimize your own consumption: Use your solar power directly โ e.g.โฏFor example, for your wallbox, heat pump, or heating element.ย
- Cleverly circumventing the 60% rule: The EMS ensures that the limitation only applies at the grid connection point โ not at the inverter.ย
In concrete terms, this means: Your HEMS intelligently distributes the solar power generated to your consumers in the house โ e.g.โฏe.g., heat pump or wallbox โ so that no more than 60% is generated at the grid connection point.% of your PV output reaches the grid connection point.โฏ% of your PV output reaching the grid connection point.ย
- Store electricity instead of wasting it: When electricity prices are negative, your battery storage is charged intelligentlyโinstead of sending the electricity back to the grid.
Conclusion: The future belongs to intelligent energy management
The Solar Peak Act is an important step toward grid stability and a sustainable energy future. For you as a PV system operator, this means more responsibilityโbut also more opportunities.ย
With a system like Leaflet HEMS, you are well prepared: you use your electricity efficiently, remain flexible, and actively support the energy transition.ย
