How do solar panels fare in a SHTF scenario? From global monetary collapse to EMP? That would be the only reason I would get one.
Then you need just a couple panels plus batteries in the basement or crawl space. If you use solar for anything more than Fridge/freezer and incidentals you are wasting lots of money. for example, solar electric heating will not work at all. Solar A/C is at least feasible but still too pricey. The only reason solar works at all is massive subsidies by rate payers (net metering) not mentioned in the article.
