Their output almost never meets nameplate numbers. Output is subject to vagaries of the sunshine. Output is not controlled to prevent overcharging of the battery. My recommendation for a battery-only electrical system, particularly if the battery is a light weight and relatively expensive lithium device is to take it home between flights and put it on a charger-maintainer recommended by the battery's manufacturer. I had readers doing this with SVLA batteries 25 years ago who reported excellent performance and longevity from the battery. This was common to both sail plane owners and owners of powered ships with electrical needs but no engine driven power sources.

He did finally have a generating system installed for convenience, but the fact that he ran a commercial operation with a 'total loss' system shows it can work well. I wish I could tell you the size of the battery he used, but I can't remember and he never knew (good pilot, but mechanic, not so much...).
