ᐅ Photovoltaics and Building Biology

Hello,

How are these two topics related? What should be considered if you want to install a photovoltaic system but also want to ensure it is done in a building-biological way? Thanks for the input.

Since photovoltaic systems are installed outside living areas, any material-related effects are negligible from a building biology perspective.

What matters from a building biology standpoint are the effects of the electrical current. Electromagnetic pollution caused by a photovoltaic system is low if installed correctly, especially compared to the magnetic alternating field generated by a transformer-powered halogen lamp or a small radio placed next to the bed.

The most significant factor is the correct low-electromagnetic-emission routing of the connecting cables and the location of the inverter. Inverters should be installed at a greater distance from bedrooms and resting areas used during the day. For those sensitive to electromagnetic pollution, the inverter should not be placed in a storage room adjacent to the bedroom.

Excellent, thank you very much for the detailed response.

This is quite an interesting situation, and I wonder about it too. The link provided is good. I believe that high-quality materials must be used in a solar power system, such as in the inverters but also in other components.

However, I am convinced that the exposure to electromagnetic pollution from a solar power system is relatively low.

I can fully agree with that. However, I see the issue with transformerless inverters. They create an alternating electric field on the solar modules, which generates electromagnetic pollution. Still, in general, the exposure to electromagnetic pollution is much lower. Perhaps some aspects are also overestimated.

I agree, and especially when it comes to the topic of electromagnetic pollution, discussions can become quite heated. I also believe that solar panels are relatively safe in terms of electromagnetic pollution, provided that high-quality materials are used.
