I have a 26' trawler
and have room for a single
100 watt panel on the roof of the wheelhouse. The panel will be used mainly to keep batteries
charged while on a mooring
. Any time the sun is coming over the stern I have a couple of antennas that will probably cause some shading. I am in Alaska
so sun angles are low even in summer. I have thought of two 50 watt panels
wired separately with two controllers to minimize shading issues. Do you think the extra cost would be worth it? With this small array I also thought PWM controllers would be fine. 235 AH house and 100 AH starting.
