Is RHI payment for GSHP affected by addition of Solar PV and batteries?

Very fortunately managed to qualify for RHI in Summer 2021 (before it closed in Spring 2022).
Qualifying system is GSHP feeding UFH.
Incentive payments are delivered over 7year period with annual reporting required to notify government of any changes to the house which may affect heat requirements.

What I hadn't known when planning the GSHP in 2019 and installing late 2020 was how steeply electricity costs would rise.
Now considering solar PV and batteries to offset electricity costs. Calculations are complicated. One big unknown is whether we'll lose some of the RHI payment if PV and batteries are installed.

Does anyone have experience or knowledge of this?

Thanks in advance.

    Maybe worth posting it on the green and ethical forum lots of good wisdom on there.

    I get the RHI for my Air Source Heat Pump.  The fact that I had solar panels (and a battery) did not enter into the consideration of the RHI payment.

    RHI payments are for the heatpump and have no relationship to any other microgeneration stuff that you might have, like solar (whether its thermal or electric), batteries or even a wood burning stove.

    The RHI payments were set by OFGEM and are inflated (by whatever random formula that they use) over the seven years and AFAIK don't really take into account the price of energy or even the rate of inflation.
    So rest assured tat you'll keep getting your payments providing you recertify every year that you still own it. (our seven years ended a couple of year ago, and we got just over £5k back)
