New French wood 2 storey Garage, PV & electrics installation.
clockmanFRA:
PV goes on the slate roof mountings.
This system I am installing for mounting the PV panels is called GRASOL, and yes its no longer sold by Wholesalers and the like.
But all other systems, Fisher etc are very similar but not always interchangeable.
This slate roof is 5.47 meters wide and I am using all the width for the 2 rows of 5 panels.
Each panel is 1040mm wide and each double holding clip between panels is 26mm and with the panel single end clips taking up 30mm and i allow a extra 40mm at each rail end. Most PV clip manufactures are now about the same.
So i have made each of the 4 aluminium rails 5470mm long. These particular design of rails come at 4.2m long so I have added an extra 1.27m . These are the aluminium joints with stainless steel Allen cap 8mm diameter threaded bolts. The underside of the rail is serrated along its length so gives a sure locking to the brackets from the slate and to the joining bars.
The other small locking 8mm threaded units in that plastic bag in the Photo is for locking the rail to the roof/slate upright bracket. Its adjustable so the rails can be kept level and straight with each other.
I always put good scaffolding up when doing a roof. And with PV on rails its a real pain getting a standard crawler ladder to go under the rails and be able to keep pulling the crawler out. So i use short ladders that i hang on a roof /slate/rail holding bracket, with the ladder footed at its base with a large wood block screwed to the scaffold wood boards, that are in turn well affixed to the scaffolding. These 2 photos show the method.
All 4 rails now firmly attached and awaiting a non windy day to fit the PV Panels, I have no help here as the Covid brings many regulations on travel and Curfews here in France, so i have installed the electric winch. Its good for 200kg so i can lift 2 PV panels at a time with a special lifting cradle.

ClockmanFRA;
Is this the same one that you installed all the slate on?
Those look "professionally" installed!
Cheers on the continuing installation !

Hi
If you don't need the complexity of the Fluke or Robin type of instruments Sealand did a range of individual instruments. I had their RCDd tester and their Earth Loop Impedance tester. I have seen both of them on EBay for under £100. I also still have an apprentice training 500V hand crancked megger, I can remember the number of times I've been pushing the crock clips into the leads and someone has given the handle a turn.
