Beginner's guide to solar PV

Chris Pearson

Any recommendations for some simple guidance on solar PV please?

I want to get a better idea of what may (or may not) be feasible at home before I obtain quotes. So not too simple, but I think that the Code of Practice might be too detailed and technical.

  • A simple question, but Uncle Google does not help.

    I gather that there is normally an a.c. isolator means of isolation adjacent to the inverter. What sort of cable is normally used to connect that to a CU please? T&E?

    I ask simply because I want to get my installation "solar-ready" as far as possible.

    Mine has standard T&E.  It's no different to any other circuit. For some reason the installer decided to add isolators next to the inverter and also in the meter cupboard near the consumer unit. I don't know why, as I could isolate it by flipping a breaker.

    Could be T&E but depending on your installation the volt drop (rise) requirement is likely to be more onerous in order to avoid "nuisance tripping" of the G98 overvoltage protection.

    But often its run in SWA to avoid needing an RCD due to the circuit route or hazards.

    Isolation by the inverter is recommended for maintenance and testing of the equipment, including functional switching, but not necessarily mandated.
