Solar panel on roof

Post by gypo »

Im thinking of fixing a panel permanently on the roof of our high top van, I have been looking at these semi flexible ones. Does anyone have one fixed to the van permanently, is it rigged to change both batteries and what are the results like?

I know the following thread starts out referring to doing this on a westy, but in the usual 80-90 fashion, it soon drifts into 9 pages of general "solar panel on roof" stuff = http://forum.club8090.co.uk/viewtopic.php?f=39&t=127964" onclick="window.open(this.href);return false; Lots of info there ;)

No good for what we want because it outputs 319v DC :shock:

Normal "camping" ones output around 19 Volts DC open circuit and are connected to a "charge controller" to regulate that down a bit to ~14 Volts.

The 100 watt Semi Rigid ones seem to be a very popular fitment on our camper vans...literally 'glued' to the roof using 'silcoflex' and then run through a charge controller for correct charge levels.

'Keith' on here, uses a charge controller with TWO battery outlets so both starter and leisure batteries are charged, although, if you have all your camping ancillaries connected to the leisure battery and a normal split charge system fitted, there should be no need to charge the starter battery as it isn't being drained whilst camping.
All the people I know who have fitted one of these panels are reporting great results, with little need for any other power source whilst camping.

Many thanks, wouldn't be better buying a kit that includes the regulator or buying them separately?
Thanks

Looks fine, though it doesn't say anything about the spec of the control unit, like does it have a Low Voltage Cut-off circuit built in (to protect your leisure battery against damage from running below ~11.5 Volts). Nor does it mention MPPT circuitry that many folks are going for these days (details HERE)

Yes that looks OK, a bit cheap in price but if it does what it says then great :) I think someone else on that other thread ^^^ had one of those.

I very much doubt this will be a MPPT controller despite what it claims.It will be a normal regulator.

The controller and panels you linked to will do the job fine the controller is just not a MPPT, not that you really need one for a single panel
