756.00 kWp Solar PV Design for an Advanced Manufacturing Site in Gloucester
PVSol rooftop solar PV layout for a 756.00 kWp system designed across long industrial roof sections at an advanced manufacturing site in Gloucester.
Nortcel was asked to prepare a concept solar PV design for a large advanced manufacturing site in Gloucester.
The project required a substantial roof-mounted PV system that could make use of the long industrial roof sections while working around rooflights, roof geometry and practical module zones.
The challenge
The site had a large roof area, but the available space was divided by repeated rooflights and long roof sections with different east and west facing aspects.
The design needed to maximise usable PV capacity without forcing modules into unsuitable areas. It also needed to test how much of the generated electricity could be used onsite against a high industrial demand profile.
The solution
Nortcel developed a 756.00 kWp roof-mounted solar PV design across 6 main module areas.
The system used 1,680 Trina Solar modules and 15 SolaX inverters. The layout followed the industrial roof geometry, with separate east and west facing module areas modelled across the main roof sections.
Project results
The PVSol simulation estimated annual solar generation of 714,075 kWh / year.
The model showed 701,457 kWh / year used onsite and 12,618 kWh / year exported to the grid. This resulted in 98.2% own power consumption and 16.8% self-sufficiency.
Estimated avoided emissions were 335,335 kg CO₂ / year.
Energy profile
Annual energy profile showing onsite PV use, grid export and consumption coverage for the 756.00 kWp rooftop solar PV design.
The energy profile shows how almost all modelled PV generation is used onsite, with only a small amount exported to the grid. It also shows how the rooftop PV system contributes to the wider electricity demand of the manufacturing site.
Design outcome
The design showed that the site could support a significant rooftop PV system with very high onsite utilisation.
The output provided a clear concept-stage basis for reviewing roof capacity, generation potential, inverter strategy and next-stage project development.
