Manufacturing Solar ROI: How a 1.58MW Ontario Array Generates $12.5M in Savings
Otter Energy is a leading Canadian provider of truly turnkey solar energy and battery storage systems. Founded in 2009, the company specializes in high-performance engineering, procurement, and construction (EPC) for commercial, agricultural, and industrial facilities across Canada. As the only ISO 9001-certified solar installer in Canada, Otter Energy has delivered over 170,000 MWh of installed capacity, helping brands like Schutz achieve energy independence and meet ambitious net-zero targets. Headquartered in Picton, Ontario, with offices in Toronto and Moncton, Otter Energy’s in-house team of engineers and project managers provides end-to-end management for some of the largest rooftop solar installations in the country.
The Challenge
Shielding industrial margins from grid volatility and carbon costs Large-scale manufacturing facilities, such as the Schutz Canada facility in Belleville, face a significant challenge: managing high operational energy costs while trying to reduce their carbon footprint. Industrial buildings often have massive roof areas that sit underutilized, while the business inside remains exposed to unpredictable hydro rates and rising carbon taxes.
For global manufacturing leaders like Schutz, energy is not just a utility, it is a business risk. “Corporations in all industries face growing pressure to reduce and report on their operational carbon footprint,” notes the Otter team, emphasizing that solar is a critical tool for cutting Cost of Goods Sold (COGS) and meeting ESG goals simultaneously. The specific challenge for the Belleville project was to install Ontario’s largest rooftop solar array (1.58MW) while navigating complex utility requirements and a shifting incentive landscape.
The Approach
De-risking a record-breaking installation with turnkey expertise Otter Energy’s strategy for commercial solar is defined by total project ownership and financial transparency. Their process, which they call “Solar Made Simple,” starts with a detailed feasibility study and hydro tariff analysis to build a proposal showing the client’s precise expected ROI.
For the Schutz project, Otter Energy executed a truly turnkey plan:
- Engineering & Procurement: Utilizing its ISO 9001-certified process, the in-house team designed a state-of-the-art array using high-performance PV modules.
- Rebate Concierge: A critical pivot occurred mid-project when Ontario expanded its rebate programs. Otter Energy worked with Schutz, the IESO, and local utilities to retroactively secure additional funding through the DER Solar Rebate program.
- Installation & Management: To ensure minimal disruption to manufacturing operations, Otter Energy’s in-house electricians and installers managed the entire build without outsourcing labor.
By effectively “pre-purchasing” electricity at a fixed cost per kWh for the next 30 years, Otter Energy helped Schutz hedge against future inflation at a fraction of standard utility rates.
Results
Record-breaking ROI and energy independence The collaboration between Otter Energy and Schutz resulted in one of the most successful renewable energy projects in Ontario’s history. The results provide a bankable proof of concept for large-scale industrial solar:
- Massive Financial Impact: The project is projected to deliver $12,567,428 in lifetime savings with an impressive IRR of 31.10%.
- Rapid Payback: Despite the scale of the 1.58MW array, the system achieved a payback period of just 3.5 years.
- Significant Carbon Reduction: The array prevents 528,300 kg of CO2 emissions annually, helping Schutz meet its sustainability milestones.

Frequently Asked Questions: Industrial Solar ROI
What is the average ROI for industrial solar in Canada?
In 2026, most large-scale manufacturing solar projects in Canada see an Internal Rate of Return (IRR) between 15% and 30%. Factors such as local hydro tariffs, roof orientation, and the ability to stack federal tax credits—like the Clean Technology Investment Tax Credit (ITC)—heavily influence these returns. As seen in the Schutz case study, high-efficiency arrays can achieve an IRR as high as 31.10%.
How does the Clean Technology Investment Tax Credit (ITC) work for businesses?
The Canadian federal government provides a 30% refundable tax credit on the capital cost of solar PV and battery storage systems installed before 2034. For a $1M project, this effectively reduces the net investment to $700,000. To qualify for the full 30%, businesses must meet specific prevailing wage and apprenticeship requirements; otherwise, the credit is reduced to 20%.
Can solar energy help reduce a factory’s Cost of Goods Sold (COGS)?
Yes. By “pre-purchasing” electricity at a fixed, lower rate for 25–30 years, manufacturers can significantly lower their operational expenses (OpEx). Solar energy directly offsets daytime peak demand—when industrial electricity rates are often highest—shielding the facility from grid volatility and rising carbon taxes. This reduction in overhead directly improves the margin on every unit produced.
What is a typical solar payback period for an Ontario manufacturer?
While the Canadian average ranges from 5 to 8 years, sophisticated industrial installations in Ontario often achieve a payback period of 3 to 5 years. This accelerated timeline is driven by the combination of high industrial hydro rates, the 30% federal ITC, and provincial demand-response incentives like the IESO’s DER programs.
