Project Overview
Sustain Commercial Solar has designed a 31.16 kWp solar PV system for Arthur House in Manchester. Located on Chorlton Street, this grid-connected PV system utilises the available roof space to generate renewable energy.
System Specifications
The solar PV installation at Arthur House features:
- 31.16 kWp total system capacity
- 76 HT-SAAE HT54-18X-410 solar panels covering 148.4 m² of roof space
- Two FoxESS T15-G3 inverters with optimised string configurations
- Dual orientation design:
- 38 panels facing northeast (44°) with 10° inclination
- 38 panels facing southwest (223°) with 10° inclination
- Grid-connected system with 3-phase connection
- Mounted roof installation
Technical Details
The technical design of the system includes:
- Performance ratio of 83.01%
- Specific annual yield of 804.65 kWh/kWp
- Yield reduction due to shading: 5.1%
- Inverter sizing factor of 103.9% for both inverters
- String configuration:
- Each inverter has two MPP trackers
- Each MPP tracker has a string of 19 modules
Energy Production
Based on simulation using climate data for Manchester (2001-2020), the system is expected to:
- Generate 25,099 kWh annually
- Export 100% of generated electricity to the grid
- Have standby consumption (inverters) of 26 kWh/year
- Avoid 5,190 kg of CO₂ emissions per year
Environmental Impact
The environmental benefits of the system include:
- Annual CO₂ emissions reduction: 5,190 kg
- Contribution to renewable energy generation in an urban environment
System Layout
The system utilises the building's roof with:
- Northeast array: 38 panels arranged to maximise morning generation
- Southwest array: 38 panels positioned to capture afternoon sunlight
- Panel spacing and positioning designed to minimise impact from shading
Parts List
The main components of the system are:
- 76 x HT-SAAE HT54-18X-410 PV modules
