Also on my wish list besides a new prop is a 21% efficient solar panel of around 1 square meter. cleversolar.co.uk/shop/solar-panels/solar-panel-kits/flexible-solar-panel-kit-12-24v-1096446.html I would opt for a 100 Watt/24Volt kit with MPPT as opposed to a PWM Controller. This, in Scotland during Summer laid flat on a panel on the stern, will likely output a continuous 2 amps @ 24V or close to 50 Watts, which should drive my boat at 1.5 knots on solar alone without using any battery with the new prop. My domestic electrics though under sail are 1 amp @ 24 Volt and includes all instruments, VHF and chartplotter. The Raymarine tiller pilot current draw varies, so the minimum I would expect is to run all instruments and the tiller pilot on an average day with no battery drain.
