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.
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.
Electricity usage • 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%)
Cruising Stats 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.
51:24 hours cruising 77.2 miles covered 18 days cruising, 12 days moored 39 locks 5 Tunnels including Harcastle, Froghall and Leek tunnels
Power required for electric propulsion
1,017 watt hours per hour cruised 677 watt hours per mile cruised
(Real world figures for the electric propulsion on Firecrest over the month of June)
Propulsion 52kWhrs (25%) Domestic 160kWhrs (75%) Total 212kWhrs
Sources of electricity
Solar Panels 93kWhrs (44%) (nearly twice what we used for our electric propulsion) Genset 119kWhrs (56%) Genset run hours 16
Note: Cruising time is based on time from unmooring to starting to moor up. It excludes stops for water and fuel, but includes waiting for locks and sitting in locks waiting for them to fill or empty.
We have had two new solar panels delivered to Firecrest. One is now fitted to the roof, but neither are yet connected so are not yet adding to our solar power.
Work in progress
As I write this it is now 12 days since we ran our generator and our batteries are still at 60% so there is no need for us to run it again for a few more days. – Brillient.
