In March 2022 I finally wired the new solar panels on our electic narrowboat, increasing the capacity of our solar panel array from 1KW to 1.5KW.
I also improved the electronics that monitors the power we get from our solar panels and the power in and out of our battery.
I was interested to see how much of the electricity we use for propulsion came from our solar panels. It is nice to see that even in April we got 2.5 times the power we used for propulsion, and 56% of our total electricity from our solar panels.
• Propulsion – 47 KWhrs (22.5%)
• Domestic – 162 KWhrs (77.5%)
• Total – 209 KWhrs
Sources of electricity
• Solar panels – 117.5 KWhrs (56%)
• Genset – 63 KWhrs (30%) (2 hrs per week)
• Battery – 28.5 KWhrs (14%)
67miles traveled #
40:40 hours crusing time #
0.71 KWhrs per mile cruised
1.17 KWhrs per hour cruised
# Note: this includes cruising upstream on the Thames for 24 miles.
I try to collate these figures every month but as experience proved from last year sharing them is not my forte.
