RE: Solar Power When Off-Grid from Hurricane
You are viewing a single comment's thread:
Its certainly a great asset in times when the main power grid is down. Always assuming that the panels are not being damaged by the storm as well. And that the sun comes back soon.
But the battery backup can prevent the worst, I guess, if you are not wasting too much power for unneccessary things. I have been wondering, for example, what happened to the food in deep freezers and fridges of the people, if the power is down for several days. I guess that can lead to a significant financial loss. And a nasty smell.

Yes, exactly right on the damage part. They are pretty resilient though, and the solar install folks claim they actually strengthen the roof. I'm not sure about that, but they definitely provided shade for that afternoon sun facing roof over our garage and dramatically lowered the temperature in the attic/garage by shading that side of the roof that was previously hit by full sun. The potential for damage is another reason I am a fan of the individual micro-inverter type setup, so that if one or more panels damaged, the others keep producing.. Yes, many of our neighbors had significant cost for food loss in fridge and freezers. We have a quarter cow plus other stuff in ours that thankfully was saved and not at risk. Plus it was nice to have the cold drinks handy!
I only have a small freezer for a single household, but even that would mean a loss of a few hundred Euros, I guess. I would not be happy if all the stuff spoils.
