As an individual, sure. That's something relatively manageable. With solar and batteries, it's easy to keep your essentials powered. But that's not what the commenter asked. They asked why commercial spaces don't adopt solar so readily. They're not in the market to go off grid. It's not a real selling point. If the power goes out, the warehouses often still run tasks and office workers can generally be sent home. Shoppers will have to wait it out. It's such a rarity, just about no business, at least not here, loses any significant money in power failures because they're so rare as it is.
