I have a 50 watt panel and a Morningstar controller. It does a decent job keeping my battery charged.

I have a flexible 25 W panel and it does a decent job (about 1 A of charging current in normal circumstances; this could be improved with beefier wiring (voltage drop) and possibly with better placing of the panel). I have a much smaller battery bank (2 x 55 Ah), so my charging needs are smaller. We don’t have any shore power in the Club, so all charging is either the motor or solar. But of course, this all depends on how much power you use, so YMWV. The most important part of the system is the controller. Don’t take any shortcuts there. Gensun and Morningstar have very good options available. If you are looking ahead, install a controller that can handle more power. But you would be hard pressed to find enough space to install enough panel capacity to provide more than 10-15 A. Marek 1994 C270 Legato Ottawa, ON
