It seems the installer has decided to walk away from his obligation to issue a COC for an installation completed on one of my customers properties.

The customer has lost faith in the installer and has requested I do a full inspection on the entire property ... including the solar installation.

Many of the issues have been attended to ...for example he did return and fit surge arrestors on the PV input ... upgraded the board to fit the Surge arrestors.

I have attended to the AC side of things ... Rerouted and replaced cabling ... upgraded all the DB's etc. but we still have a few issues.

So my plan is to share my experience ... not being an experienced solar installer (limited knowledge of solar) ...this is going to be an interesting experiment ... if you dont try you dont learn.

So we going to start on the roof and work down.

What are the requirements for the solar panels ... where do we start.

Firstly a sketch of the layout

Then a snap shot of the panel description

the layout of the panels (string as it is refered to)

Type of connectors and the wiring layount on the roof

If any fuses are required

Type of channeling/tubing and the route used to get the wires from the roof top to the inverter ... making sure it is not mixed in with AC cabling.

Earthing requirements

Can you think of anything else?

You have to ask yourself ... is the cheapest quote the way to go.
