Tiny Solar Barn

I'm building a tiny solar powered barn. The solar system is hooked up to a device which sends data to the cloud. The system has a solar output of 400 watts at ~1 amp during the afternoon. Here's a view of the logs from the device, which measures various voltages, temperature of the battery compartment and controls a series of relays.


My house is not a suitable candidate for solar due to a few Redwood trees and a very large Maple tree in the backyard. Today is the shortest day of the year. That means the amount of sunlight falling where I live is the lowest it will be today. Even still, the batteries in the barn are staying topped off and I have plenty of power to run tools, lights, chargers and other devices.
