First things first
How do I find an electrician?
Recommendations are best. Be sure to compare several offers. Use our form further down in the article to do so.
How much does an electrician cost?
The cost of an electrician can be up to 20% of the total cost of a photovoltaic system - around €200 to €350 per kWp installed.
Do I need an electrician?
You can install a PV system yourself. However, you will need an electrician to connect it to the grid.
Regional or National
It is better to choose a local specialist company. Be sure to insist on a free on-site appointment before installation.
How do I find a good electrician for photovoltaics?
As a first point of contact, you can look around in your neighbourhood. Ask what experiences people have had with the photovoltaic specialist company. Ask the following Questions:

Do I absolutely need an electrician for photovoltaics?
You are not legally obliged to hire an electrician to install photovoltaics. You can carry out all tasks yourself, except for the grid connection and commissioning. Nevertheless, it is advisable to integrate a qualified photovoltaic electrician into the project as early as possible. This will ensure that the PV system generates the highest possible yield.
What tasks does the photovoltaic electrician take on?
A photovoltaic electrician is usually responsible for the planning, installation and maintenance of the PV system.
planning
The basis for planning is a free on-site appointment to take stock. The specialist then lays out and selects the individual components and creates circuit diagrams. He also creates a yield and economic forecast. These documents are used to create a quote. As soon as you commission the electrician, the components are ordered and the installation is planned.
registration with the network operator
Please note that you must register the PV system with the grid operator eight weeks before installation begins. The grid operator will carry out a grid compatibility check within this period. You may only proceed with the installation once approval has been given. The electrician can also register the system for you.
installation
During the installation process, various electrical work is carried out. This includes laying cables, connecting the PV modules and the inverter, and possibly installing a power storage unit. In addition, the connection to the house's electrical circuit is made and the connection to the public power grid is prepared.
power connection
A licensed and certified electrician is required for the connection to the power grid and for all other connections on the AC side. This is required by law and stipulated in Section 81 Paragraph 1 of the Renewable Energy Sources Act (EEG 2021). Registered electricians are registered with the local grid operator.
commissioning
The grid connection is already part of the commissioning of a PV system. Once the connection is completed, the PV system is started up and produces solar power for the first time. A checklist is then processed and a commissioning report is prepared by the electrician. Without these documents, you are not entitled to the feed-in tariff. Commissioning is legally required by a certified electrician.
Can any electrician register a PV system?
You can authorize any third party to register your PV system. It does not matter whether the registration is done by an electrician, another consultant or another family member. All you have to do is sign an authorization.
maintenance
Maintaining a PV system prevents performance losses or failures of the PV system. It is a good idea to ask the electrician who installed it to carry out maintenance as well. Depending on the location, annual or biennial maintenance is recommended.
This Tasks The electrician carries out the following when maintaining PV systems:
- Control of error messages from remote monitoring of PV systems
- Correcting the cause of the error
- Visual inspections and measurements on PV systems
- Testing the functionality of inverters, modules and remote monitoring
- AC-side connection of PV systems (meter cabinet, commissioning of the systems, reporting of the systems to the grid operator, grid testing)
- replacement of defective devices

How much does the electrician cost for a photovoltaic system?
An electrician costs up to 20% of the total cost of a photovoltaic system. This corresponds to around €200 to €350 per installed kWp. The size of the PV system has a direct impact on the installation costs per square meter. Larger PV systems have lower installation costs.
What characterizes a good electrician for PV systems?
A good electrician has good references. In addition, the following points make a good electrician for PV systems:
- regional company
- Free on-site appointment
- Clear and open communication
- accessibility in emergencies
- Use of high-quality components and modules from well-known manufacturers
- The warranty of the solar modules should be at least between 15 and 25 years
- The inverter warranty should be at least 10 years
Can I connect photovoltaics myself?
You can also connect a PV system yourself. However, an electrician is required to connect the AC voltage side and the grid connection. The law requires that a PV system be commissioned by a certified electrician. The problem with self-installation is that specialist companies often refuse to commission it for liability reasons. In addition, self-installation entails some risks.
- loss of performance, yield and profitability
- Expiration of the guarantee and warranties
- danger potential
Therefore, it is better to play it safe and work with a professional.
