I deal with warranty claims all the time. Damaged ≠ defective.

Have you seen the test where they drop bowling balls on various roof materials?

For me, it comes down to the fastening to the substrate roof and the overall shape of the structure. The latter isn't a warranty issue, the former should be.

Sounds like an interesting opportunity to test the strenght of this system under such an extreme environmental condition, and to figure out how some eventual developments could be applied to increase its safety in a hurricane-prone area.

Skip to 17:19 to see the part about solar roofs.

Looks like they haven't done squat with the solar roof tiles in 5 years, they planned more installs but the cost has exploded by an additional $70,000 per install.
This looks like a dead end. Any one waiting for solar roof tiles, just get regular solar panels.

I find the non-solar tiles interesting for their durability.

Cost-wise, were it my money, the winner is vertical panels sized to fit a standing seam metal roof.

www.remodelista.com: Remodeling 101: 15 Luxuries Worth Considering in Your Remodel

'Luxuries' one and two are a standing seam roof and solar panels (ten is acoustic insulation for bathrooms).

Solar panels on top of a modern industrial type building like a hospital may have survived, but if the island was covered with panels on the wonky built standard housing, it wouldn't have survived. So maybe if they rebuild the entire community with modern Florida like codes maybe. But who's paying for that?

To me it make more sense to not put the resources for electric generation in the path of natural disaster. Building nuclear plants on the Japan coastline was a mistake. Building large scale solar panels in the common path of hurricanes is a mistake. So put the nuclear plants and the solar plants out in the desert. Wind plants on the northern plains. We need to power in the grid somewhere, it doesn't have to be local. Putting that generating equipment in the line of fire just seems like asking for it.

Get the power lines underground in PR and then they will be less susceptible to damage. Would have made recovery much quicker. Also they politicized the whole thing. The first contractor was hired and then fired before they even gave them a chance over politics starting the whole process over.

It's rocket science.


hwww.stem.org.uk: The Mathematics of Satellite Design - Origami

Simplest design would be a WWII Quonset hut frame oriented East-West, with a standing seam solar roof from the ground to over the summit, with the North side up on a thermal mass wall with North view windows.

Until a few years ago I didn't know about Quonset huts, yet I noticed a lot of commercial buildings shared some of their features. Nowadays if I would have a house built from scratch, I would be quite inclined to have it built as a Quonset hut with some energy-efficiency and water-saving features added. Its structural strenght is what has led me to enjoy their design.

That isn't rocket science. I should know, but go ask some other rocket scientist. Just because it is on a structure named satellite don't make it one.

Works better that way.

I just use the aphorism because it came from a website on satellite design. In any case, the thought was that the added expense of a furling mechanism might be cost saving in the long run.
