Slate roofs are renowned for their elegance and longevity, often lasting over a century with proper maintenance. However, their installation and upkeep can be costlier than traditional roofing materials. One of the primary concerns when installing solar panels on slate roofs is the potential risk of damage during installation. Slate tiles are fragile and can crack or break if not handled correctly. Therefore, hiring experienced professionals who understand slate roofing is crucial.
In practice, most commercial solar panels achieve efficiencies between 15% and 22%. This discrepancy between theoretical and practical efficiency arises from various losses. One major factor is thermalization loss, which occurs when photogenerated charge carriers (electrons and holes) lose energy in the form of heat before being collected as electrical current. Additionally, there are recombination losses, where charge carriers recombine before contributing to the electric current, and reflective losses, where sunlight bounces off the surface of the cell instead of being absorbed.
