Why Design Matters for Solar O&M

When evaluating SATs, I want to consider whether the failure of any individual hardware component could threaten the system’s overall production. In the case of a decentralized SAT, for example, each row’s independent motor is powered by its own dedicated solar panel (wi

3 Ways to Prevent a Solavalanche

Because the face of solar panels are fabricated from glass, there’s no surface area/friction for snow to grip onto, and nothing to stop it from building up, eventually releasing in an avalanche manner, in the form of what we Alpine-ites like to refer to as a solavalanche.
