FAQ

1. Do I need permission to install a balcony solar kit?
In most cases, you don’t. If you’re renting, it’s good practice to inform your landlord — but legally, installations that don’t alter the building permanently are allowed. We also provide a standard form you can use.

2. Do I need an electrician to set it up?
No, our kits are designed for plug-and-play installation. You just mount the panels, connect the inverter, and plug it into a standard outdoor Schuko socket.

3. How do I apply for the government subsidy?
Each federal state has different rules. We provide a step-by-step guide and links to current SolarPlus or balcony solar programs. In Berlin, for example, you can apply online and get up to €250 back.

4. Will this reduce my electricity bill?
Yes. Depending on your sunlight and usage, the 400W or 800W system can save between €200–€350 per year on average.

5. Is the system certified for use in Germany?
Yes. All our components meet German standards, including VDE, TÜV, and safety regulations for grid feed-in.

6. What happens on cloudy days or in winter?
Solar panels still generate energy in lower light, just less than on sunny days. The inverter ensures whatever energy is generated is used immediately in your home.

7. Can I track how much energy I’m producing?
Yes, the micro inverter has built-in monitoring. You can see daily and cumulative energy data through a mobile app or web dashboard.

8. What’s the difference between 400W and 800W kits?
The 400W kit is ideal for small balconies or limited sun exposure. The 800W version provides more output for larger spaces and is the current legal feed-in limit in Germany

9. Is it legal to feed energy back into the grid with a balcony system?
Yes. In Germany, feeding small amounts of solar energy back into the grid using plug-in systems up to 800W is legal, as long as the equipment is certified and your system is registered with your local grid operator and the Marktstammdatenregister (MaStR). We provide simple guidance for both steps.

10. Do I need a smart meter?
Not necessarily. In most regions, your existing Ferraris or digital meter can be used with small-scale balcony solar setups. However, some utility providers may recommend or require a bidirectional meter. If needed, your energy provider must replace it free of charge.

11. What kind of socket do I need?
Our kits are compatible with standard Schuko sockets, which are common across Germany. For long-term use, a dedicated outdoor socket with its own fuse is ideal, but not required by law.

12. What’s the lifespan of the panels and inverter?
The flexible solar panels typically last 15–20 years with minimal efficiency drop-off. The micro inverter has a lifespan of around 10–15 years and includes warranty coverage.

13. How much space do I need on my balcony?
The 400W kit (2x200W panels) requires approximately 1.5–2.5 square meters of flat or railing-mounted space. The panels are flexible and lightweight, which helps with different mounting positions.

14. Can I take the system with me if I move?
Yes, the kit is fully portable. Simply unplug it, dismount the panels, and reinstall it at your new home.

15. What happens during a power outage?
The system automatically shuts off for safety. This is a standard requirement in Germany to protect grid workers. Once power is restored, the system resumes operation.

16. Do I need to insure the system?
While it's not required, some home insurance policies already cover small solar installations. If you’d like, we can provide tips for asking your provider or suggest affordable coverage options.
