Supply and Installation of addition solar PV panel generation system

The University of Salford seeks proposals to supply and install additional PV generation to one of its buildings. The Northern Engineering Robotics Innovation Centre (NERIC) was constructed in 2022 for the University of Salford, the first building on its new Innovation Campus on Frederick Road, M6 6AP.

At the time it was fitted out with 15 kWp onto its higher flat roof. The roof was originally designed to accommodate more panels, but these were reduced in a value engineering exercise. 2.0 Goods and Services to be provided The University seeks to double the amount by adding another 15 kWp bringing the total to 30kWp on the existing higher, gravel ballasted flat roof, easily visible from google satellite, while still maintaining access to service plant and the PV system.

We can provide hourly data for 2025 for import, generation and export and would want a model worked up using this data as a basis but on double the existing building consumption (c55,000 kWh/yr to 110,000kWh/yr) as we are expecting this to rise very shortly. Modelling should show generation, import, export, costs saved over 20-year period as a minimum, carbon saved using current grid carbon intensity, payback periods etc including inverter replacement at year 10. Work on a current electricity import price of 28p/kWh and a grid (import) carbon intensity of 177g CO2e/kWh and an export price of 5.6p/kWh Can you please provide us with a proposal and quote to include. • A cost/carbon/payback model based on the above parameters. • A rough breakdown of costs in your quote rather than a single figure. • Provide the data sheets for the proposed panels, non-penetrating fixing system and inverters. • The combined panel/fixing weight as kg/m2 as installed on the roof. • State the panel and inverter warranty.
