Question for people who have installed solar in a property that's used by other people: Is it easy to manage and perform basic troubleshooting? A cousin proudly showed me her solar setup at a vacation home including the app showing her electricity savings and the various hardware components and all I could think of was the things that can go wrong at our own property when I am not around and my parents, kids, or siblings are using it. After serving as my extended family's "IT support" for decades and dealing with a neverending stream of headaches relating to wifi, printers, Nest, unresponsive PCs, TV settings, car apps, and so on, I'm wary of installing a major system that requires someone to be basically on call to deal with minor problems or major outages as described in TFA.
