Make Solar Panels

Lisa Said:

If We All Had Solar Panels Would It Make The Planet Hotter?

We Answered:

Solar panels are not Mirrors. Photovoltaic (PV) cells convert solar energy to electricity. They do have somewhat reflective surfaces so a certain percentage of light might be reflected but this would generally be reflected up towards space (making the planet cooler). The electrical power generation means that some percentage (about 13% for most commercial units) is turned into electricity instead of straight heat on the roof. There is a slight increased risk of house fire due to the electrical equipment on the roof but no more so than any other electrical device.
