124.7 kW rooftop solar offsetting 99.4% of electricity at a wood products manufacturer in Tilbury, Ontario
Commercial solar delivering 99.4% annual electricity offset for a wood products manufacturing facility in Ontario.
A high daytime load against a roof asset approaching the end of its replacement cycle.
Wood products manufacturing facilities typically operate with steady annual electricity demand driven by machinery, material handling, ventilation, and facility systems. Electricity remains a meaningful operating cost that is difficult to reduce through efficiency measures alone.
At H&H Wood Products, the objective was to significantly reduce reliance on grid electricity while maintaining stable production operations. The challenge was achieving a near-complete annual electricity offset within the physical and operational constraints of an existing manufacturing facility.
Size to the service. Mount without penetrations.
A rooftop solar PV system was engineered with capacity and layout determined based on roof availability, electrical infrastructure, and operational requirements specific to wood products manufacturing.
Rather than maximizing installed capacity, the design focused on precise alignment between annual generation and usage. This resulted in a solar system capable of offsetting nearly all of the facility’s annual electricity consumption while integrating seamlessly into existing operations. The system reached commercial operation on May 15, 2025.
The numbers, then the consequence.
- 01152,013 kWh of solar electricity generated annually.
- 0299.4% of the facility's annual electricity consumption offset by solar.
- 03Minimal ongoing reliance on grid electricity for day-to-day operations.
- 04System commissioned May 15, 2025.
Equivalent to removing 2 passenger vehicles from Ontario roads annually.
For the facilities and engineering audience.
The system consists of 124.7 kW DC (215 Thornova Solar modules) paired with 100 kW AC via SolarEdge inverter technology. Designed as a commercial solar installation for a manufacturing facility, the system was sized to closely match the facility’s annual electricity consumption profile.
SolarEdge inverter architecture supports optimized performance monitoring and long-term reliability. Ongoing production visibility and asset performance can be supported through a structured solar operations and maintenance program.
Facility characteristics that shaped the design.
- Wood products manufacturing facility with consistent annual electricity demand
- Electrical loads driven by production equipment, ventilation, and site services
- Existing rooftop suitable for high-utilisation solar deployment
- Annual load profile enabling near-complete electricity offset without operational disruption
