This study looked at how solar panels on buildings affect their heat and energy use in Mauritius. They tested different types of solar panels on the roof and walls of a typical office building to see how they made the building warmer and used energy. The solar panels on the roof helped reduce the extra heat in the building by 8% or 15%, while the panels on the walls didn't make much difference. In terms of energy use, the wall panels actually made the building use more energy by 1.66%, but the roof panels saved around 5% of energy. Overall, the roof solar panels did a better job of keeping the building cool and saving energy compared to the ones on the walls.
