I now have my new Hymer parked outside albeit without any solar panels fitted as the dealer wanted far too much when asked. They also indicated that ‘only’ 115w panels will fit. (bs)
After a question on the owners club it is feasible that a lot more can fit, although mine does have a large number of holes already in the roof making it a tad crowded. I realise it is possible to go across, eg a vent, higher but I don’t want to exceed 3.00m.
As memsahib has put a prohibition on me climbing ladders these days I’ve had to resort to a head out of a couple of skylights to give me approximate dimensions. These seem to indicate the following size of panels is possible.
1 off 700 x 1700
1 off 700 x 1300
1 off 700 x 1200 ( I was very cramped and it maybe feasible to squeeze 1250)
I‘ve looked online at Victron panels and have deduced the following sizes in Mono (is this what we would generally fit?)
1 x 668 x 1485 = 175w. @19.4v
1 x 668 x 1250 = 140w. @ 19.4v
1 x 668 x 1015 = 115w @ 19.0v A proper measurement and maybe I can squeeze a 140w
this would give me a total of 430w (or possible 455w) I would be more than happy with just 315w - but let’s see what can be done. I’m sure there’s also room for a 50w and another 115w, but let’s not go overboard for now.
now, what allowance is necessary for the additional width/length of mounting brackets?
I’ve attempted to guesstimate the size of MPPT controller required using the Victron site, and hope I’ve put the correct numbers in the calculator. The 430w suggests a 100-30 unit and 455w a 100-50. would the odd voltage of 19.0 indicated for the 115w be an issue? Should I just go for the 100-50 anyway?
Finally, I have no intention of doing any of this myself and will entrust it to professionals, but it’s very close to Christmas break and I’d like to get an idea of what is possible before troubling anyone.
here’s an aerial view of the roof, with the @%€£ radio aerial taking up some valuable roof space. I’ve decided we will not be fitting a satellite dish this time.
