TerraGen Solar

What TerraGen Solar does

TerraGen Solar (legal name TerraGen Environmental Group Inc.) is a Canadian manufacturer of commercial solar racking and mounting systems, founded in 2009 and headquartered at 120 Parsons Road, Alliston, Ontario. Originally operated as a solar EPC contractor, the company restructured in 2017 to focus exclusively on racking manufacturing, leveraging its installation heritage to inform product design. TerraGen designs, engineers, and produces rail-based aluminum and galvanized steel mounting systems for flat and pitched commercial roofs, with a portfolio that includes the TGR flat-roof system and its Dual Tilt and Elevated variants, the TGP flush-mount pitched-roof system, the TGT tilted pitched-roof system, and the TXL flat-roof landscape system launched in July 2025. The company also delivers custom mounting solutions including elevated truss systems, re-roof provisions, awnings, facade and pole mounting, and inverter racks.

The product portfolio is differentiated by configurable tilt angles, customizable row spacing, and a direct load transfer capability that holds global roof loading to as low as 2.5 lb/ft², reducing or eliminating the need for structural reinforcement. Manufacturing was automated in early 2020, raising tilt-assembly daily capacity from approximately 200 kW to 1.5 MW. TerraGen sells directly through an enterprise field-sales motion to commercial solar installers, EPCs, and developers across North America and the Caribbean; projects ship as complete packaged solutions including project-specific structural layouts and engineering documentation, with quote-based project pricing. The company holds UL 2703 and UL 3741:2020 certifications and completed a DNV bankability assessment for the TGP system in January 2025.

By the DNV assessment date, TerraGen had supplied over 350 MW of mounting solutions across thousands of projects, up from 130+ MW cited in 2024, indicating a sharp recent shipment ramp. The company is privately held and founder-owned, with Doug Jones, P. Eng. as Founder and Darren Jones as President; no institutional venture or private-equity ownership is disclosed. The team listed on the website numbers roughly 18 individuals, including operations, engineering, design, supply chain, project management, and warehouse functions. Customer references are concentrated among regional solar installers and EPCs in Canada, the U.S., and the Caribbean, suggesting a distributed, long-tail book of business rather than a few anchor accounts.

Core offering

TerraGen Solar designs, manufactures, and ships rail-based solar PV racking and mounting systems for commercial and industrial rooftops. The portfolio includes flat-roof systems (TGR, TGR-Dual Tilt, TXL), pitched-roof flush-mount and tilted systems (TGP, TGT), and custom mounting solutions. Products are sold as complete packaged solutions including detailed structural and engineering designs directly to installers, EPCs, and project developers across North America and the Caribbean.

Product overview

TerraGen Solar is a North American manufacturer offering a suite of solar racking solutions for all roof types. Its product portfolio centers on four core racking systems: TGR (flat roof rail-based system supporting any tilt angle and row spacing), TGR-Dual Tilt (dual-tilt flat roof variant), TGP (flush mount pitched roof solution), and TGT (tilted pitched roof solution adding module tilt up to 20 degrees). The company recently launched TXL, a new flat-roof landscape racking system. Custom solutions including elevated truss systems, inverter racks, and structurally challenged roof adaptations round out the offering. All products ship as complete packaged solutions including engineering and structural layout designs, and are manufactured using aluminum and galvanized steel construction.

Products and services

• TGR Flat Roof Racking System A rail-based solar PV mounting system for commercial flat roofs using a base rail, top rail, tilt triangles and clamps. Supports any tilt angle (5-20° portrait, 5-35° landscape), any inter-row spacing, and customizable load transfer points; accommodates skewed arrays and complex roof layouts. Available with ballast, mechanical attachment, or hybrid uplift resistance, and maintains global loading as low as 2.5 lb/ft². Designed for commercial solar installers, EPCs, and developers installing on flat-roof commercial buildings.
• TGR-Dual Tilt (TGR-DT) System A dual-tilt flat-roof racking system designed to increase module density and energy yield (kWp) on commercial rooftops without sacrificing module support or voiding module warranties. Can be ballasted, mechanically fixed, or hybrid, with customizable tilt angles and row spacing and a global load rating of 2.3-4 psf. Targeted at commercial solar projects seeking higher density per roof area.
• TGP Flush Mount Pitched Roof System A flush-mount pitched-roof solar racking solution compatible with standing seam, trapezoidal, roll-on bitumen, and shingle roof types. Features height adjustments to accommodate roof undulations, telescopic bonding splices, and flexible roof attachment options including penetration through high rib of metal profiles. Designed for commercial solar installers and developers on sloped commercial roofs. The DNV bankability assessment (2025) found no reported failures or warranty claims on the TGP system.
• TGT Tilted Pitched Roof System A tilted pitched-roof solar racking solution that adds module tilt of 0-20° on commercial pitched roofs to maximize energy generation. Pre-assembled components reduce installation time, and a universal 30-50mm click-on module clamp speeds mounting. Compatible with standing seam, trapezoidal, corrugated, and shingle roof types. Targeted at commercial solar projects that need tilted module configurations on sloped roofs.
• TXL Flat-Roof Landscape Racking System A flat-roof landscape solar racking system engineered for performance, flexibility, and ease of installation on commercial flat roofs. Features a significantly lower profile to reduce snow accumulation and wind exposure, pre-assembled components that eliminate the need for N/S measurements on site, support for multiple tilt angles and row spacings, multiple uplift resistance options, and reduced ballast requirements without compromising strength. Launched in July 2025.
• TGR-Elevated System A TGR variant that elevates the racking array above the roof surface, ideal for roofs with obstructions and for green roof installations, with the additional benefit of increased bifacial energy generation. Targeted at commercial solar projects where roof obstructions or green-roof configurations prevent direct roof contact.
• Custom Solar Mounting Solutions Fully customizable solar mounting solutions from TerraGen covering elevated truss systems, re-roofing re-provisions, awnings, facade mounting, pole mounting, inverter racks, and configurations for structurally challenged roofs. Targeted at commercial solar projects with non-standard mounting needs, future maintenance access requirements, or aesthetic and multi-equipment integration requirements.
