I'm looking to assemble a small solar system at home, maybe a 200w panel for starters, and maybe 220 Ah of batteries. Small, but a toe in the water. I'm going to keep it 12V, I won't be running an inverter. This would also mean any (small) accessories would also work in the car. Now trying to do the energy use calculations...started wondering, what are the best (or your favorite) 12V accessories? So far on the list are: A 12V fan (maybe the Fan-Tastic Vent Endless Breeze) 12V LED lighting (brand unknown?) 12V power for my laptop 12V charger for AA batteries (Eneloops). 12V charger for ham radio What else would you recommend, for starting with a small 12V system? What 12V items would you not want to be without?
