Good setup. Twice as good, supplying two households. I guess in a way you're seeking your own electricity to your tenants
A bit of cloud didn't matter to much but shadows do. I was totally dependent on solar on the boat for the laptop ( navigation), warning systems, lights, self steering gear, so I paid a lot of attention to the system. I found the shadow of a thin rigging wire across a panel on a sunny day would reduce the output by half. So watch out for branches casting shadows, and dirt building up. That counts for more than you'd expect.
