Weather has been brilliant the last couple of weeks, shame we’ve not spent it on the water, but that doesn’t mean I’ve not been thinking about it.
I’ve been considering how to keep an eye on our boat while we’re far away, on and off I’ve thought about building my own monitoring system using a Raspberry Pi, some basic sensors and maybe an old phone or mifi for comms. That would be a fun project, but may well take a long time to get going. And before that I need to solve the power source, so I’ve been thinking about solar.
I am planning to mount one or two panels on the deck, possibly 2x35W panels either side of the forehatch, or maybe just one similar shape panel behind the hatch.

From asking around, googling and watching videos online I think I’m going to need ETFE coated semi-flexible panels.
Getting this fitted will help keep our batteries topped up and then open up the option of extra electronics, perhaps even remote monitoring.
I’ve been seriously considering VirCru, even with it’s annual subscription cost, it does look very good value for money, especially if I compare it to the running cost of a homebrew system (VirCru is about £10/month where I’d probably need to get a data-sim, account and a mifi, which would come out at probably more than £10/month. The initial hardware costs are fairly low, admittedly not as low as digging a pi out of my desk drawer and attaching stuff to it, but definately more reliable!
