Top five risks of solar energy

Micro-cracking, or micro-fractures, can occur in solar panels when panels are subject to strong wind forces. The silicon used is very thin and when it expands and contracts, or when it''s damaged by wind or falling debris, it can crack, making the panel less efficient at absorbing light and storing energy.
