Below, we address the most common questions regarding solar installation in Canada.
Frequently Asked Questions
General Solar Energy FAQs
Solar panels rely on light, not heat, to produce electricity. In fact, solar panels are often more efficient in colder temperatures. For more technical details on photovoltaic performance, you can visit the Natural Resources Canada website.
Most Canadian businesses see a full payback within 3 to 5 years, depending on available incentives. You can explore our Commercial Solar Solutions to see how we maximize your ROI.
Frequently Asked Questions
Financial & Technical Questions
Yes. From the 30% Federal Investment Tax Credit to provincial grants, there are many ways to lower your upfront costs. To see a full list of opportunities, visit our Commercial Solar Incentives page.
One of the most frequent Solar Energy FAQs we receive is about maintenance. Because there are no moving parts, solar arrays require very little upkeep. Occasional cleaning and annual inspections by our ISO 9001-certified team will keep your system running at peak performance.
Frequently Asked Questions
Commercial Solar FAQs
Commercial solar refers to solar energy systems installed on businesses, industrial buildings, warehouses, offices, and other commercial properties. These systems are designed to offset electricity costs, stabilize energy expenses, and improve long-term operating margins.
The cost of commercial solar depends on system size, energy usage, roof or land availability, and electrical infrastructure. While upfront costs vary, most businesses see strong returns through energy savings, incentives, and accelerated depreciation.
Yes. Commercial solar is one of the most reliable long-term investments businesses can make. It reduces operating costs, protects against rising utility rates, and often delivers predictable returns over 25+ years.
Canadian businesses may qualify for federal, provincial, and utility-based incentives, including grants, rebates, and tax advantages. These programs can significantly reduce the upfront cost of commercial solar installations.
Most commercial solar projects take several weeks from design to commissioning, depending on system size, permitting, and site conditions. Installation is typically scheduled to minimize disruption to business operations.
Yes. Commercial solar systems can be installed on flat roofs, sloped roofs, ground-mounts, and parking canopies. Each system is custom-designed to maximize energy production and structural safety.
When properly engineered and installed, commercial solar systems do not void building warranties. Otter Energy works with building owners, insurers, and engineers to ensure full compliance and risk mitigation.
Commercial solar panels typically last 25–30 years or more. Inverters and electrical components may require replacement during that time, and all major components are backed by manufacturer warranties.
Yes. Battery storage allows businesses to store excess solar energy, reduce peak demand charges, and maintain power during outages. Solar-plus-storage is increasingly popular for facilities with high energy reliability needs.
No. The incentive is still active, though the rate changed from $860/kW-AC to $770/kW-AC for complete applications submitted after June 30, 2026. The microgeneration rate ($1,000/kW-DC for systems up to 10 kW DC) did not change.
No. The Save on Energy Retrofit solar incentive applies strictly to rooftop-mounted systems. Ground-mount commercial solar installations are not eligible under the current Retrofit Program guidelines.
Yes. Both can be applied to the same project. The federal ITC (30% refundable) applies to your net eligible costs calculated after Save on Energy is deducted. Combined with accelerated capital cost allowance (ACCA), eligible businesses can achieve effective first-year cost reductions of 50–55%+.
The incentive caps out at 50% of eligible project costs, paying out at a rate of $770/kW-AC (post-June 30, 2026) for rooftop-mounted systems from 10 kW to 1 MW AC. For example, a 500 kW system at $770/kW-AC equals $385,000, provided it does not breach the 50% total project cost cap.
With Save on Energy and the federal ITC strategically stacked, a typical payback is 6–9 years for solar-only installations (500 kW+, high daytime load). For Class A customers combining commercial solar with battery energy storage (BESS), payback periods drop to just 3–5 years by drastically reducing peak demand charges and Global Adjustment fees.
Yes. Save on Energy mandates a pre-approved Retrofit application before any binding commitment is made, including issuing a purchase order for equipment. Applications submitted after purchasing equipment will be rejected. Our in-house project managers ensure your funding is locked in before a single dollar is spent on hardware.
Price per watt tells you what hardware costs, but omits scope details like structural engineering, interconnection, commissioning, and warranties. Normalizing proposals to the same scope is essential to determine true total cost of ownership.
Engineering capability determines whether your ROI model holds up. Credible EPCs provide transparent yield models showing soiling, temperature, and degradation assumptions, alongside stamped structural and electrical design assessments.
Frequently Asked Questions
Residential Solar FAQs
The cost of residential solar panels in Canada depends on system size, roof type, and energy usage. Most homeowners see significant long-term savings, especially when incentives and rebates are applied.
Yes. Residential solar panels can significantly reduce electricity bills, protect against rising energy costs, and increase home value. Many homeowners reach payback within several years.
Absolutely. Residential solar systems are designed to perform efficiently in cold climates. Panels often work more efficiently in cooler temperatures and still generate power in winter conditions.
Homeowners may qualify for federal, provincial, or municipal solar incentives. These programs can significantly reduce upfront installation costs and improve return on investment.
Most residential solar panels last 25–30 years or more and are backed by strong manufacturer warranties. Inverters and other components may have different warranty periods.
Yes. Battery storage allows homeowners to store excess solar energy for use during outages or peak pricing periods. Battery systems can be installed alongside or added to existing residential solar systems.
Frequently Asked Questions
Agricultural Solar FAQs
Agricultural solar refers to solar energy systems installed on farms, barns, livestock facilities, greenhouses, and rural properties. These systems help farmers reduce energy costs, improve operational resilience, and offset rising electricity rates.
Yes. Farms often have high and consistent energy usage, making agricultural solar highly cost-effective. Many operations see significant long-term savings and improved cash flow after installing solar.
Solar panels can be installed on barn roofs, machine sheds, grain storage buildings, ground-mounted systems, or unused land. Each agricultural solar system is designed around the farm’s layout and energy needs.
The cost of agricultural solar depends on system size, mounting type, and electrical infrastructure. Incentives and energy savings often make solar an attractive long-term investment for farms of all sizes.
Farmers may qualify for federal, provincial, and agriculture-specific incentives designed to support renewable energy adoption. These programs can significantly reduce upfront installation costs.
Yes. Agricultural solar systems are well-suited for rural environments and can be paired with battery storage or generators to support off-grid or remote operations.
No. Solar systems are designed to integrate seamlessly with existing farm operations. Installations are planned to avoid interference with equipment access, livestock movement, and day-to-day workflows.
Agricultural solar panels typically last 25–30 years or longer. Systems are engineered to withstand harsh weather conditions, including snow, wind, and temperature fluctuations common in rural Canada.
In many regions, net metering programs allow farms to export excess electricity to the grid and receive credits on future energy bills. Availability depends on local utility policies.
