More Fixed Balcony Solar, and Impact on EPC?

[Ferdinand]

Slightly speculative, but worth a discussion I think.

One thing I see balcony solar being used for is a small fixed installations as a cost-saver.

That is, we use a more fixed small install on wall, roof - whatever - done via something more substantive than "hook on a balcony" done under Permitted Development, and then use a connection to a plug-in unit to avoid the complex wiring etc.

AIUI the limitations are 2 kWp of solar panels, and 800W output.

Does anyone have any thoughts on this?

And does anyone have any thoughts on the impact of a 1kw or 2kw balcony solar system on the EPC number?

This could be a way for LLs trying to meet the EPC C which is I think a requirement for 2030.

We've recently had our EPC redone and 12.5kw of panels added a few points but surprised me how little it added. We've got a 4kw MCS system and 8.5kw self installed and the Assessor seemed to struggle with getting those entered into the system. He ended up putting the panels in by area as a percentage of roof area covered. I got the impression that assessor wasn't too familiar with anything non standard so maybe there are alternative ways that may get a better score??
