Most frequently asked questions

What is solar energy?

The word solar comes from the Latin "solaris". It means "related to the sun". Solar energy is therefore the energy of the sun, which is converted into electricity with the help of solar cells and an inverter. Solar cells are usually made of silicon, which occurs very frequently on our planet, for example in sand. In this silicon there are tiny particles called electrons. When they are hit by the sun's rays, they move. Since energy is always created by movement, this is how electricity is generated from sunlight. The conversion of light into electricity is also called the "photovoaltaic effect". For this reason, solar systems are also called photovoltaic systems.

Do my solar panels produce electricity when the sun is not shining?

Even when the sun is not shining, your solar system produces electricity. Not only the direct sunlight is used, but also the indirect light. You will not be generating as much when the sun is not there but you will see some production.

How long do the modules last?

Our solar modules have high quality and durability. With careful installation and use, the service life is around 25 years.

What requirements must my balcony meet in order to use the solar set?

Your balcony only needs to meet two conditions for the use of our solar modules. A suitable balcony railing and a power socket, that's all you need.

Can I use the modules on a smaller balcony?

This is usually not a problem. The solar modules do not need to be fixed in a row. They consist of 4, 8 or more panels of 90cm x 54cm each. These can be oriented in different ways, for example, two on the front and others around the balcony shape. The more panels you can fit on your railing the more energy you will generate.

How do I install my solar panels?

Installation is super easy: you can attach each panel to the balcony railing in no time with the included mounting straps. Please make sure that all straps are firmly connected to the solar panel. This ensures adequate protection against wind and other weather conditions. The mounting straps are specially made for outdoor use and are of high quality. After the solar panels are mounted on the balcony railing, they can be connected to the micro-inverter. The wiring is very simple. You need to connect the micro-inverter in the middle of the solar set. The next step is to connect the plug to the micro-inverter, and then simply plug it into the power socket on your balcony. Once everything is plugged in, you will immediately start generating electricity during the day. All data can be viewed in our mobile WeDoSolar app.

Is a building permit required for the solar installation?

No, a building permit is not required for private use on your own property. However, as a tenant, the consent of the landlord is generally required, however take into account that our solar modules also serve as a sight protection which no one can forbid to use. However, it is within your responsibility to check the local laws and requirements for your building.

Can the landlord prohibit the installation of my balcony solar system?

In our opinion, the landlord cannot in principle prohibit the installation and operation of the solar system. In a recent case in Stuttgart, the District Court with file number 37 C 2283/20 with article 20a (state objective of environmental protection pursuant) that the tenant's interest in operating a balcony solar system generally outweighs the landlord's interest in using the rented property in accordance with the contract. The use of solar systems was objectively beneficial in terms of environmental protection. In this case, the landlord could not prohibit the use. WeDoSolar is not currently aware of any other law cases that arrised. In addition, WeDoSolar balcony solar panels are characterised by a particularly attractive and high-quality appearance that surpasses the look of conventional balcony privacy screens. This is yet another reason why landlords might not object to the use of WeDoSolar balcony solar set.

How does the registration with the energy supplier work?

After installation, you should register your solar system with the energy provider. Please bare in ming that laws and regulations vary depending on the country and location. We highly advise to check your local regulations.
