With a solar system on the roof of your home, you not only contribute to the energy transition in Germany, but also manage to reduce your own energy costs in the medium term. More and more homeowners are now opting for a solar power system on the roof, thereby promoting the production of green electricity.
One photovoltaic system is not only good for the environment and ensures more sustainability in modern and increasingly green everyday life, but also means a lot of responsibility. So is a regular maintenance and testing of photovoltaic systems in Germany is mandatory. The so-called DGUV V3 test put here the Basis in terms of accident prevention In order to ensure safe and proper operation of a photovoltaic system, a specialist must be commissioned to carry out an inspection every year. Newly built plants must also first after the DGUV regulation 3 be accepted so that the solar system and all associated components can be checked.
Here you can find out how the inspection of solar systems works and what homeowners should consider during an inspection. In the following you will get an overview of the process of testing the solar systems.
1. Recurring examination based on legal principles
A solar system is a highly complex technical system and may only be put into operation after professional installation. After the first operational acceptance, a recurring test is carried out based on the submission of the DGUV A3previously BGV A3to ensure safe and proper operation. A solar system also includes all other technical connections, so that a Testing of portable electrical equipment takes place.
Not only is the performance of solar systems regularly tested, but also completely checked every four years. Even without the legal regulations, regular maintenance and testing of the photovoltaic system makes a lot of sense, as it is also of great insurance relevance. If a solar module is damaged, careful documentation is required. This also includes all proof of required safety work and tests. Only if there is complete documentation is it possible to receive compensation from the insurance company in the event of damage. A review of the system configuration and technical components thus also protects against high financial damage.
1.1. Testing by a specialist electrical company or a testing organization
Every four years, the solar systems of private individuals are checked. Either a specialist from a specialist electrical company or a testing organization is responsible for the maintenance and testing of the photovoltaic system. The most important criterion for the recurring test is very precise documentation in order to be able to prove any problems at an early stage. These test points are taken into account for a solar system:
- Visual inspection for defects in wiring harnesses or damage to insulation
- Functional test by a inverter
- Comparison of data: System configurations are compared with the measured data. Changes to the system are immediately noticeable.
- Metrological check of the system: insulation resistance, total power, short-circuit current
The duration of the test depends on the size of the solar system and the associated building services components. Accordingly, solar heating should also be checked in order to be able to use the heating energy ideally. The test points also include an effectiveness test, in which all protective measures of the solar systems are examined.
After the test, however, the operator of a solar system should not just rest on the laurels of the seal of approval. It is therefore recommended that the inverter be checked daily in order to identify defects at an early stage.
