While solar technology is generally considered safe, the public has raised certain health concerns, which typically fall into three categories: electromagnetic fields (EMFs) and radiation, chemical exposure from the materials used in solar panels, and the potential thermal impact on homes and neighborhoods.
A study from the University of California, San Diego, found that solar panels can reduce the roof temperature by an average of 5 degrees Fahrenheit during the day. This cooling occurs because solar panels absorb sunlight that would otherwise hit the roof and convert it into energy, reducing the heat transferred to the building.
One of the most common concerns is the potential for solar panels to emit harmful electromagnetic fields (EMFs) or radiation. Since solar systems generate electricity from the sunlight, panels and their associated equipment, such as inverters and wiring, produce EMFs.
Recycling programs for solar panels help manage end-of-life materials, preventing environmental harm and protecting public health. The long-term health benefits of solar panels, including reduced pollution and lower carbon emissions, far outweigh the minimal risks associated with their use.
Common property hazards to be assessed when considering the installation of roof mounted PV systems include: PV systems introduce new electrical components such as wiring, invertors, control equipment as well as the PV panels themselves. These components can be subject to failure, damage, or heating, increasing the risk of fire.
Although some solar panels contain metals considered toxic in large quantities, it is very rare for humans to become exposed to these elements at any point in the equipment life cycle. In the best interest of our customers and the planet, PPM does not install solar panels manufactured with toxic materials.
