The European Commission introduces a novel project aimed at enhancing the effectiveness of the EU's electricity distribution network.
In the heart of Germany, the rise of balcony solar power plants, or Balkonkraftwerke, has been a growing trend. These compact solar systems, designed for urban dwellings, have made it easier for homeowners to harness solar energy. However, as systems grow in size, so do the regulations.
For small-scale balcony solar plants, up to 800 watts, installation is relatively straightforward. These units can be set up as plug-and-play systems, requiring no special permits or approval, and can be installed by the user without the need for an electrician or landlord permission.
However, systems exceeding the 800-watt threshold, such as a 4000-watt setup, fall into a more regulated category. These systems require formal grid registration, possible permits, professional installation, compliance with safety and building regulations, and likely landlord permission.
Key points for a 4000-watt balcony solar plant in Germany are:
- Permits and Approvals: Systems over 800 watts require notification and approval by the grid operator (utility company). The system must comply with grid connection rules and safety standards to prevent risks to the grid.
- Grid Registration: You must register your installation with your local distribution system operator. This process involves submitting technical documentation including system specifications and proof of compliance with technical standards.
- Installation by Professionals: For larger systems like 4000 watts, installation by a certified electrician and possibly certification by an authorized expert might be legally required to ensure safe, compliant connection to the household grid.
- Insurance and Liability: Notify your homeowner's or renter’s insurance to cover the installation and any potential liabilities.
- Building and Safety Codes: The system must comply with applicable building codes, fire safety regulations, and structural load requirements.
- Lease and Landlord Permissions: Unlike smaller plug-in units often exempt from landlord permission, a 4000-watt setup may constitute a significant alteration, so landlord approval or lease agreement review is advisable.
- Feed-in Tariffs and Net Metering: Larger systems can often participate formally in feed-in tariffs or net metering schemes allowing excess energy sales to the grid, but must be registered and meet technical standards.
Two popular options for 4000-watt balcony solar plants in Germany are the Okta-Set from Kleines Kraftwerk and the Okta-Set from solago. Both include high-quality solar modules and inverters, but each offers unique features.
The Okta-Set from Kleines Kraftwerk includes eight bifacial XL solar modules, each 500 watts, totaling 4000 watts. It also comes with the Anker Solarbank 3 Pro inverter and a smart meter, along with various accessories like MC4 solar cable sets and Y-adapters. The price for the Okta Set from Kleines Kraftwerk is 1,739 euros.
On the other hand, the Okta Set from solago includes 8x 500 Watt, bifacial, glass-glass, full black modules and the Anker SOLIX Solarbank 3 Pro inverter. It also features an adjustable system for flat roofs or the floor. The Okta Set from solago is priced from 1.799 Euro with a discount code ("our website30").
It's important to note that as systems grow in size, they may no longer be considered balcony power plants. Exceeding the 800-watt limit results in the system being considered a regular PV solar system, requiring registration, connection through an electrical specialist company, and compliance with stricter regulations.
In conclusion, while small balcony solar plants (up to 800 watts) can be installed simply and independently in Germany, a 4000-watt balcony system falls into a more regulated category. It is recommended to consult local utility providers and an authorized electrician to ensure full compliance before installing such a system.
- Systems over 800 watts, like a 4000-watt setup, necessitate formal grid registration and may require permits, professional installation, and landlord permission in Germany.
- Both the Okta-Set from Kleines Kraftwerk and the Okta-Set from solago are popular options for 4000-watt balcony solar plants in Germany, offering high-quality components and unique features, but they are no longer considered balcony power plants once they exceed the 800-watt limit.
- When installing a 4000-watt balcony solar plant in Germany, it's essential to comply with building codes, ensure fire and safety regulations, register with the grid operator, and possibly work with an electrician and landlord to avoid potential risks and liabilities.
