Installing solar panel and dodgy work

[Herman]

I see your panels all spread around on roof in pairs on thier own small frames
also I read you are somewhat wobbly and roof is high and could be dangerous
Is there no way you could get these PVs on a ground frame where access would be easier and less arduous to deal with wiring?
Maintenace and keeping PVs clean would be simpler 😐

I wish I could mate even though we are on eight acres we are surrounded by trees so the roof is the better option at the moment just a though was wondering if I could run a two main string lines + and - and plug into it from the panels which would mean i would only have to join into 1 line with a branch plug so basically have two branch plugs on the panel connecting into another branch plug on the main line my only fear is it may get to hot and I am back to square one.

Ok, so a ground type frame is not practical for you.

However I would still recommend looking at some way to get those panels off the roof. If height is an issue to clear tree shading then perhaps a pole mounted frame(s) for six or eight panels.
Your present setup is IMO always going to have difficult cabling issues even with flexible or solid electrical conduit because its over a hot hot iron roof and between your spaced out frames will always be exposed to UV and lots of heat. This could be solved by wiring each frame through the roof but drilling holes in the iron roof is probably not a great idea.

A pole mounted frame would mean much simpler inter-panel wiring and a common pair down the pole. You could also mount a breaker box on the pole to switch PV strings etc..
The PVs would be better ventilated too with easier escape of hot air from below them.

Thanks for the advice it is appreciated I would have loved a ground mount as well but have been working with what we have trying to keep the cost down

OK, understand, I'm sure you will get the wiring sorted out

I've heard a coat of yellow paint will protect plastic from the UV (it's not the heat, it's UV light that cooks the plastic).  sounds reasonable, but I have no proof yet, my piping is only a year old.

I have also heard that from some of the electricians but they generally say any good quality outdoor paint but I need to make sure there is no effect from the paint to our water supply which is from the roof before I start that one

Not sure it has to be yellow. I!ve painted some of mine white and the paint does really help reduce or actual stop the burn damage.

I have all the new panels up and running world of TSMC are a world of difference compared with the DCH BX 65 they harvested 1.7 KW in 3 hours full cloud cover and light rain the BX 65 I was lucky to get .5 of a KW in that time even with 12 of them.

the only thing left to do on the roof is to tidy up the last piece of conduit and paint it then in goes the new Selctroincs Invertor Charger
