Jonstar Sustainability’s Summer of Solar 2024

As we push on into our 5th year installing Solar PV, we have had some really good projects being completed and about to start this summer, albeit the summer definitely started late itself!

Care Home in Rugby
This care home in Rugby was in need of a new roof, so in conjunction with a roofing contractor we put together an in-roof Solar proposal of 102, 415W panels to match the sites consumption. The generation in year 1 is forecasted to be 41,330kWh, reducing their communal bill by 39%. This in turn gives the home a payback in year 5. By tweaking how they run schedules for laundry, etc. the payback could be reduced even further. The client is now looking at several other care homes as part of a national roll out to re-roof and add Solar.
Installed as part of the SolarEdge system were additional components to make the system safer and easier to monitor. A Firefighter Gateway with a PV stop button installed by the main doors and a Modbus meter to monitor export to enable the SolarEdge platform to show the sites consumption of the Solar as it is generated.

New Build Café in Kensington
For one of our regular clients, Jonstar was asked to provide the Solar PV installation on a new build in Kensington to meet the energy efficiency requirements that were stipulated in the SBEM calculations. We installed a 12.04kWp system, which is forecast to generate 10,260kWh in its first year.

Nottingham College
As part of a full refurbishment of this city center college building, Solar PV had again featured as one of the measures to improve the energy efficiency of the building. Having worked on the development of the project from the beginning with the design consultants. Jonstar was able to follow the project through to the installation of the Solar PV, providing a completely joined up process from concept to commissioning as the work progressed through the stages.
The array consists of 74, 430W DAS solar panels, SolarEdge optimisers and a 25kW SolarEdge inverter. There was also a Firefighter Gateway installed to allow integration into the fire system and automatic shutdown of the inverter in the event of the fire alarm going off.
The system is forecast to generate 22,720kWh a year and a potential saving of up to £6,800.00.
