When considering self-consumption through solar panels, it is natural to be concerned about the potential risks associated with this technology. Do they pose health hazards? Can they cause fires? How do they behave in extreme weather conditions? Let us examine these questions and provide useful information to help ease your concerns.
Solar panels and electromagnetic waves: what science says
One of the most common concerns relates to the potential impact of solar panels on human health due to electromagnetic waves. However, the exposure level emitted by solar panels is far below the safety limits in force in Belgium.
The International Commission on Non-Ionizing Radiation Protection (ICNIRP) recommends a limit of 85 microteslas (µT) for the general public. At one meter from photovoltaic modules, the electromagnetic field reaches approximately 45 µT, which is well below this limit.
Near an inverter, the field can reach 50 µT, which also remains under the ICNIRP limit. Therefore, there is no reason to worry about installing solar panels on your roof from an electromagnetic radiation perspective.
Solar panels and fire risk: can they cause a fire?
Although solar panels are safe for health, they can, very rarely, be the cause of a fire. They are connected to the home’s electrical system as well as the grid, and any electrical system carries a certain level of risk.
However, this risk is extremely low if the installation is properly carried out by a qualified and certified professional. A fire may occur in cases of manufacturing defects, improper installation, or outdated internal electrical systems.
To prevent any incident, it is essential to entrust your photovoltaic installation to a professional certified by a government-recognized body. These certifications ensure compliance with safety standards, particularly electrical ones.
Electrical safety: the role of certification bodies
The connection of solar panels to the grid is strictly regulated in Belgium. For safety reasons, you must obtain an electrical compliance certificate (ECC) before your installation can be commissioned.
An independent body (such as AIB Vincotte) verifies the safety of photovoltaic installations. If your system does not meet the standards, AIB-Vincotte will require corrective measures.
Solar panels and weather risks: what to expect
Heatwaves and overheating risk
Heatwaves are becoming more frequent and intense in Belgium. Although solar panels require sunlight to operate, they do not perform well under excessively high temperatures.
Above 25°C, their performance decreases by approximately 0.5% per additional degree.
However, from a safety perspective, heatwaves do not cause dangerous overheating or fires. Solar panels are designed to withstand high temperatures.
Conclusion
In conclusion, the risks associated with solar panels are minimal, provided they are correctly installed by a certified professional and comply with Belgian standards. When choosing panels, always prioritize reputable brands and certified installers.
Solar energy is a safe, clean, and sustainable solution for powering your home in the BENELUX region. With proper maintenance, your panels will provide many years of reliable performance and peace of mind.
