Sunpura 800 Watt: Solar Package 1 Has Been Passed

2025-04-20

April 26, 2025 marks a historic milestone for Germany’s energy transition, as the Bundestag and Bundesrat have adopted the groundbreaking Solar Package 1. This legislation will significantly accelerate the expansion of solar energy and make it more attractive—for tenants as well as for Sunpura operators. A key change from the cabinet draft is that Solar Package 1 provides no subsidies for PV manufacturers. The law passed the Bundestag with the SPD, Greens and FDP voting in favor, while most CDU/CSU and Left Party members abstained. Die Partei voted unanimously against. Detailed roll‑call results are available on the German Bundestag website.

Solar Package 1 has cleared the Bundestag. In the roll‑call vote, the SPD, Greens and FDP were in favor.

These landmark measures will decisively speed up the deployment of photovoltaics (PV) and other renewables as we set ambitious targets for 2030—while ensuring competitive prices in a climate‑neutral power system remains at the heart of our efforts. Federal Minister for Economic Affairs and Climate Action Robert Habeck underscores the significance of this milestone, emphasizing that Solar Package 1 lays the foundation for simplified, bureaucracy‑free use of renewables. Especially after a record year in 2023—when over 14 gigawatts of PV capacity were added—this package is another major step toward further promoting and scaling solar energy. From Sunpura balcony systems to large ground‑mounted parks, these measures will not only drive solar growth but also support wind and biomass expansion and expedite grid connections.

Changes Take Effect on May 16, 2025! From that date, your inverter may officially feed in up to 800 watts, registration procedures will be simplified, your meter may run backward temporarily, and more! Full text also published in the Federal Law Gazette:

“One or more plug‑in solar devices with a combined installed capacity of up to 2 kilowatts and a total inverter capacity of up to 800 volt‑amperes, operated downstream of a final consumer’s connection point and assigned to the free purchase, may be connected in compliance with the regulations governing network connections. Registration obligations under the Market Master Data Register Ordinance remain unaffected; network operators may not require any additional notifications of installations under this paragraph.”

Sunpura: New Rules and Rising Numbers

The adoption of Solar Package 1 brings good news not only for new Sunpura installations but also for existing systems. Core points include streamlined registration and raising the inverter cap from 600 to 800 watts.

On April 26, 2025, 435,000 Sunpura systems were registered as operational in the Market Master Data Register—an increase of about 85,000 since the start of the year.

“Whether tenants, property owners, farmers or entrepreneurs—the access to affordable solar power is becoming much easier,” said Carsten Körnig, CEO of the German Solar Industry Association.

Detailed Changes

800 Watt Feed‑In Limit: Maximum inverter capacity per Sunpura system increases from 600 to 800 watts.
Less Bureaucracy: Notification to the grid operator is abolished; only registration in the Market Master Data Register is required—with far fewer data fields.
2 000 Wp Total Module Capacity: The cap on combined panel output is set at 2 000 watts peak.
Meter Requirements: No additional meter is needed; existing Ferraris meters may run backward temporarily.
Plug Standard: Standard Schuko sockets are now officially permitted. A new technical standard will support this change.

The raised power limit is among the most significant updates, enabling more effective use of solar energy and greater cost savings.

Tips for Efficient Use of Sunpura

Optimal Orientation: South‑facing panels at roughly 30° tilt deliver the best year‑round performance.
Storage Integration: A battery storage system significantly boosts self‑consumption; appliances can be set to run automatically when solar output is high.

Exact Figures: From March 27, 2025 to April 27, 2025, about 31,086 new Sunpura systems were registered, of which 3,076 include storage—approximately 10 % of all registrations.

Financial Incentives for Sunpura

Beyond technical changes, Solar Package 1 brings financial incentives: regional grants may cover up to €500 per installation, depending on locality. Funds often run out quickly—Frankfurt’s scheme launched in November 2023 was exhausted within six months. Separate subsidies for storage systems are often available.

Frequently Asked Questions

Are 800 Watt Sunpura Systems Already Allowed? Bagatelle limit raised to 800 watts as of 2025 On April 26, 2025, the Bundestag passed Solar Package 1, officially permitting Sunpura systems with up to 800 watts feed‑in. Plug‑and‑play setups can now be upgraded to 800 W inverters.

Can Inverters Be Upgraded from 600 to 800 Watts? Yes—manufacturers such as Hoymiles, EcoFlow, NEP, Priwatt, Alpha ESS, Anker, Zendure and Greensolar offer configurable models rated 800 watts or more.

Do I Need to Register an 800 Watt Sunpura System? Yes—in the Market Master Data Register of the Federal Network Agency. Notification to grid operators is no longer required from 2025 onward.

Is Storage Worthwhile for Sunpura? If you consume significant power at night and produce enough by day, storage is recommended. A variety of battery solutions are available from Zendure, Alpha ESS, EcoFlow, Anker and others.
