HARVEST SOME SUN

Solar & charging.

Marine solar is constrained by space, shade, motion, salt and timing. The real question is not how many panels you can fit; it is how many watt-hours reach the battery after a normal boating day.

MPPTRigid vs flexibleShade

**From sunlight to useful energy**Panel energy goes through a compatible charge controller into battery storage and loads. Illustrative harvest is 200 watts times 4 equivalent peak-sun hours times a 0.75 performance factor, or 600 watt-hours per day.Reference: Victron — Wiring Unlimited

THE QUESTION TO ASK

Will a solar panel actually keep the fridge running?

Panels, MPPT controllers, shade, and why nameplate watts are optimistic.
