When a North Toronto church sought to embody the Buddhist teaching that “harming the environment harms oneself,” they turned to solar energy and discovered that going green requires patience, planning, and the right partner.

Watch as Mark Marmer walks you through the new solar install.

The Toronto Buddhist Church first reached out to Signature Electric after watching our YouTube video showcasing the Beach United Church solar installation, a project we’re proud to call one of the most eco-friendly church projects in Ontario.

 

Their motivation went beyond simply reducing electricity costs. As the client explained, they wanted to promote one of Buddhism’s core principles: the doctrine that teaches “no entity is isolated: harming the environment harms oneself.” For them, installing solar panels was more than an infrastructure upgrade; it was a tangible expression of their faith.

The Toronto Buddhist Church is a modest two to three-story building in North Toronto, not a sprawling campus, but a tight footprint that required creative planning to maximize solar potential. Our goal was to design a system that would meaningfully offset the church’s electricity consumption while respecting the building’s aesthetic and structural limitations.

System Size: 35 kW (revised from initial 45 kW design)

Energy Offset: Approximately 30% of the church’s annual electricity consumption

Location: Rooftop installation across multiple roof sections

One of the most important lessons from this project, and something we always share with prospective clients, is that commercial solar installations don’t happen overnight. From the initial phone call to the final panel going live, this project took approximately eighteen months. That timeline might seem long, but every step serves a critical purpose.

After the church reached out, we used our in-house design software to create a preliminary system layout and cost estimate. Our initial design called for a 45 kW system based on satellite imagery and our first discussions with the client. This gave the church leadership a realistic picture of what was possible and allowed them to make an informed decision about moving forward.

Once the client confirmed they wanted to proceed, we moved into the Feasibility Assessment phase. This involved two critical workstreams running in parallel.

 

First, we engaged structural engineers to verify that the building could support the weight and wind loads of the solar array. This isn’t optional. It’s essential for the safety and longevity of both the solar system and the building itself.

 

Second, we worked with Toronto Hydro to confirm the local grid could accept the solar system’s connection.

Following the engineering assessment, we had to revise our original design. The roof had slightly less usable space than initially estimated due to HVAC pipes and vents that weren’t visible in the satellite imagery used for the preliminary review. The final system was reduced to 35 kW, still capable of offsetting roughly 30% of the church’s electricity consumption.

 

One advantage of this building was the placement of its mechanical equipment. A lot of times, the mechanical is so spread out that it’s hard to find enough space to put the panels. This building worked well, with mechanical systems concentrated in one area, leaving clean, unobstructed space for the solar array.

With Toronto Hydro approval secured and the detailed proposal accepted, we were ready to install, but the client wisely decided to pause. They realized this was the perfect time to complete some roof maintenance and repairs before the panels went up.

 

The timing makes good sense. Even if you were doing a single-family home, assessing whether the roof will need repair or replacement in the near future and acting before the panels are installed saves future labour by avoiding the need to remove those panels to access the roof.

Once the roof repairs were completed, the solar installation moved quickly. With all preparatory work completed, engineering approved, utility connection secured, and the roof in pristine condition, our team completed the full installation in approximately 2 weeks once all materials arrived on site.

 

The installation involved mounting the solar panels across the available roof sections, installing the inverter on the rooftop, running conduit down the side of the building to the utility disconnect, and connecting everything back to the main electrical room. A lift was brought in to safely run the conduit down the building’s exterior to the isolating disconnect mounted on the side of the building.

 

This is where the patience of the previous phases pays off. Because the engineering, utility approvals, and roof work were all completed properly, the actual installation was smooth and efficient, with no surprises, no delays, and no rework required.

Every commercial solar project presents unique challenges. For the Toronto Buddhist Church, we navigated several key obstacles.

 

Space Constraints: The building’s compact footprint meant every square foot of usable roof space counted. Our team optimized panel placement to maximize energy generation while working around existing HVAC infrastructure.

 

Utility Coordination: Working with Toronto Hydro to confirm grid capacity and secure connection approval required patience and persistence. We maintained clear communication with both the utility and the client throughout this process.

 

Aesthetic Preservation: The church wanted to maintain the building’s appearance. Because the roof is relatively low and the panels are positioned at the right angle, the installation is virtually invisible from street level. “When you stand in the parking lot at this angle where these are, you can’t even tell that these panels are up there,” Mark notes. “It hasn’t taken anything away from the look of the building.”

 

Optimal Sun Exposure: Location scouting confirmed excellent solar generation conditions. The roof sits above the surrounding tree line with no shading issues, a critical factor for maximizing energy production year-round.

Today, the Toronto Buddhist Church’s 35 kW solar array quietly generates clean electricity, offsetting approximately 30% of the building’s annual consumption. The panels sit unobtrusively on the roof, invisible to visitors and neighbours alike, silently embodying the Buddhist principle that inspired the project.

 

For the church’s congregation, the solar installation is more than an environmental initiative; it’s a daily reminder that care for the earth and spiritual practice are inseparable. Every kilowatt-hour of clean energy produced reinforces their commitment to the teaching that no entity exists in isolation.

The Toronto Buddhist Church project demonstrates that commercial solar is achievable for organizations of all sizes, even those with compact buildings and modest roof space. The keys to success include realistic expectations about the timeline, patience during the engineering and utility approval process, and partnering with a contractor who communicates clearly at every stage.

 

Whether your motivation is environmental, financial, spiritual, or all three, solar energy can align your organization’s values with its operations in a visible, lasting way.
