Solar Photovoltaic (PV) Installation
As part of a move towards being more sustainable and to reduce our carbon footprint, three companies were approached to provide quotations to have solar PVs installed at 17 Riduna Park.
Two companies have completed site visits and produced comprehensive quotation documents.
The other company provided a guide quote over email to be followed up with a site visit. I am yet to hear with regards to an engineer appointment and have been chasing since February.

Although the roof space available could support additional solar PV both companies have targeted the annual consumption of the office.
The overall consumption for 17 Riduna Park is considered low, totalling approximately 3,350kWh a year. If an Electric Vehicle charging point were to be placed at the office site then this would of course increase the consumption. The annual cost for office electricity in 2021/22 was £595.15.
Solar panels would not meet the first test for CIL funding as it’s not for wider community benefit, rather more of an environmental benefit. Neighbourhood CIL could be used to fund the EV Charger as this has a wider public use.
The Green Suffolk Fund offer grants up to a maximum of £2000, and this could be explored.
Members are asked to:
- Note and comment on this report
- Decide if they wish to proceed with installing solar PV equipment

If this is of interest to you, we can put together a full design and financial breakdown for you to asses.
This price has been provisionally given prior to a site survey, confirmation of an exact price will be given in writing after a site survey.
