I have had a 4kw Solar PV system for 2 years, and have claimed the FIT since it was installed. We wish to invest in more PV for a number of reasons, we have 1 EV and wish to get another, and have recently moved to an Air Pump for heating.

I wish to add more Solar PV to the garage roof, and also the North roof of house. All the new PV would be on-grid. I have a number of options, with regards to what size, but to put a number on it, we would probably add in the region of another 2kw-4kw.

Given we are claiming FIT for 4kw already, what happens if we add another 4kw? Are we able to up the existing FIT claim to 8kw? Or is it not that simple. Is there a process or guide anyone knows of that helps someone consider their options and what the implications are of increasing on an existing 4kw FIT claim?

First you need to find out if your DNO will allow it.

You will continue to get your 4kW system paid at its present tariff. Any addition will be paid at the then current tariff in the 4-10kW band, presently this is 12.13p which drops to 11.71p on 1st July.

Here's a topic where I recently asked "PV Greater than 16A/3.68kW. Who to ask? What to ask?"

You'll find some of the basics in section 10 of the PV FAQs.
