There are two problems with power use in disaster situations. One is that vital services require power, and the other is that all of the people connected to the grid want power regardless of their need. These new panels are not intended to supply power to the whole grid– they are intended to supply power to only specific essential services. Those essential services might be medical facilities, and governmental buildings, and maybe utility buildings. Another essential service might be food warehouses located in-country, probably not for freezers but for communications. The necessity of securing power for essential services will lead people to locate or prepare the space to accommodate these panels.
This concept is hardly new. The governor residence in Michigan has a solar roof made with flexible solar shingles. We installed that years and years ago. 20 years ago roll up solar panels were on the market. You could even get some that could be rolled up and carried under your arm. It highlights a problem in sustainability which is redo something that has been done years even generations before then claiming it as Their own innovation. This is more of an “yeah us, we finally did it” story.
