Elegant electrical. I used a marine through-hull plug cut through under my starboard side taillight, wired a short 3-gang pigtail to it, into which I plug an onboard charger and another extension cord. If I can plug in, I've a small electric heater that will run while my battery charges. Otherwise, I can charge from shore power and stay locked!
But the solar....now that's interesting. I'm considering some of the new low-Amp panels because my draw is so low (no converted appliances, etc.). I'm hoping to benefit (again) from your choices and follow your example of craftsmanship. Funny, as much fun as they are to use, there's something about the building, too.
