Solar if anything is something that doesn't "silently break", you literally stop getting electricity. Everyone I know with solar has it front and center how much their batteries currently have charged, if the batteries are suddenly 0% and never increases, how wouldn't people notice?
This seems to be for something like you have a bunch of solar panels on a property/land where you don't visit at all, and you use it for solar panels and you only sell the electricity. But the website seems to be marketed towards individuals, not to companies.
Maybe I just misunderstand who this is for?
