My PV panels are rated for 1" hailstones.
But not micro-meteorites, which our atmosphere conveniently turns into a light show.
At least, I'll probably need "alpha goop" or some other compliant glob to catch them before they break the tempered glass.
Hey wait a minute, no need for environmental seal! Ditch the glass entirely? But still need to protect the wafers.
What about coronal discharge? No northern lights on the moon. Do you trust that EMP hardened inverter you bought?
