How do I connect a balcony power plant?

A balcony power plant can be installed easily and quickly. It's enough to mount the solar modules, connect the inverter, and plug in the Schuko plug – this can be done in about 30 minutes, completely without an electrician. Tenants can immediately save on electricity costs and simultaneously contribute to sustainability. Since 2024, the permits for installation have been simplified.

What are the requirements?

Balcony power plants up to 800 watts (from 2025 net 600 watts) can be connected directly to a household socket without special technical knowledge. Safety standards, such as VDE-AR-N 4105, ensure compatibility and safety. These systems are particularly suitable for tenants and homeowners in Germany, as long as the balcony or terrace receives at least 4 hours of daily sunlight. Important components include solar modules, micro-inverters, and mounting brackets. DRBO Greenenergy offers high-quality plug-and-play systems that maximize self-consumption. The products are equipped with important certifications to guarantee a long lifespan and high performance.

Which permits are necessary?

For balcony power plants up to 800 watts (net), no building permit or electrician is required, only registration with the grid operator within 4 weeks. Tenants also need written consent from their landlord. Since May 2024, the rules have been simplified: systems up to 2 kWp (gross) are permit-free if installed correctly. Registration is easily done via the Market Master Data Register of the Federal Network Agency. DRBO Greenenergy provides all necessary documents, including sample letters for landlords, to simplify the process.

How do I choose the right components?

For an optimal balcony power plant, we recommend an 800-watt set with bifacial solar modules, a bidirectional inverter, and a storage unit to reduce electricity costs by 30–50 € per month. The choice of components should depend on the orientation of the balcony: a south orientation is ideal, but an east-west setup also provides a longer yield. Bifacial modules use reflections and increase performance by up to 20%. Micro-inverters with MPPT ensure maximum power output. DRBO Greenenergy offers complete sets equipped with SunLit storage units to maximize self-consumption.

How do I install the balcony power plant correctly?

Installing a balcony power plant is simple and can be done in four steps: attach the bracket, clip in the modules, connect the cables, and optimally align the modules (with a tilt of approximately 30° and facing south). Ensure that all connections are secure and weatherproof. DRBO Greenenergy sets include all mounting accessories, so you can easily install the system yourself. It is important to route the cables correctly and ensure that the angle of the solar modules is set for efficient electricity production.

How do I connect the balcony power plant to the grid?

Connecting the balcony power plant is done by plugging the Schuko plug into a dedicated household socket. The inverter is connected to the solar modules, and the circuit is switched off before plugging in the plug. An island protection ensures that the system automatically switches off in the event of a power outage. App pairing allows for system monitoring and ensures that no RCD is tripped. With DRBO Greenenergy's SunLit storage units, you can achieve zero feed-in, further optimizing self-consumption.

What mistakes should I avoid?

A common mistake is incorrect polarity or a north orientation, which significantly reduces the yield. To avoid this, measure the voltage before connecting and adhere to all applicable standards. In addition, you should ensure regular cleaning, as dirt and dust can reduce the yield. Ignoring app alarms can also lead to problems, so all warnings should be heeded.

How do I maximize the yield?

To maximize the yield, combine the balcony power plant with a storage unit and other consumers, such as a washing machine, which can be automatically activated via an app control. An east-west setup ensures more consistent energy generation throughout the day. DRBO Greenenergy offers SunLit storage solutions that allow you to store excess energy and use it for evening consumption. An annual yield of 600–900 kWh at 800 Wp is possible.
