Thought I would stick this here as this is completely non Astro related.
Does anyone have any experience with the Jaycar solar charge controllers like this one?

I have a tractor that has a moderately weak battery but which also sits unused for weeks at a time, in winter if it has not been started for a week or so I get one shot at starting it or I have to wheel the gen set and battery charger over. I was thinking of putting a solar panel on the roof of its canopy and installing a charge controller to keep it topped up. Even with a new battery it occasionally sits long enough to be a risk of not starting and in those cases it often knocks the battery around through sitting discharged.
