May is the first full month since we increased our
Solar Panel capacity from 640W to 1kW.
May has not been a good month for Solar power but we
still got more than twice the power we used for propulsion from the sun. It is noticeable how much less we need to run
the generator to keep our batteries charged.
It is now quite practical for us to cruise and live on our boat for a whole week without running the generator. Since we cook with an electric oven, electric hob and use an electric kettle, that is impressive.
Don’t tell Cheryl but I now have a cunning plan to add
two more panels bringing our capacity up to 1.5kW so that a greater proportion
of our total electricity usage comes from the sun and we can run out generator
35:41 hours cruising
56 miles covered
13 days cruising, 18 days moored
Genset use 19hrs
Rain – too much ! !
Propulsion 40kWhrs (17%)
Domestic 197kWhrs (83%)
Solar Panels 89kWhrs (38%) (over twice what we used for propulsion)
Genset 148kWhrs (62%)
Power required for propulsion
1,138 watts per hour cruised
725 watts per mile cruised
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.
