Frequently Asked Questions
What are the best commercial solar financing options in Ontario?+
For most Ontario businesses, a commercial solar loan combined with the 30% federal Clean Technology ITC and 100% Class 43.2 capital cost allowance produces the highest first-year and long-term return. The ITC reduces tax payable by 30% of equipment cost, and Class 43.2 allows 100% write-off in year one — together generating significant first-year cash flow. A Power Purchase Agreement (PPA) offers $0 upfront cost but the business does not own the system and cannot claim ITC or CCA.
What is a commercial solar PPA in Ontario?+
A Power Purchase Agreement (PPA) is a contract where a third-party solar developer installs, owns, and maintains a solar system on your commercial property. You agree to purchase the electricity generated at a fixed rate per kWh — typically 15–30% below your current utility rate — for a 15–25 year term. PPAs offer $0 upfront cost and immediate electricity savings, but the business does not own the system, cannot claim federal ITC or Class 43.2 CCA, and is locked into a long-term contract.
Does commercial solar qualify for the federal 30% ITC in Canada?+
Yes. Commercial solar systems in Canada qualify for the 30% Clean Technology Investment Tax Credit on eligible equipment (solar panels, inverters, mounting, wiring, and battery storage). For corporations, the ITC is 40% refundable — meaning if the credit exceeds tax payable, 40% of the excess is refunded in cash. Additionally, Class 43.2 provides 100% accelerated capital cost allowance in year one, generating a large deduction that further reduces taxable income.
How does Class 43.2 accelerated CCA work for commercial solar in Ontario?+
CCA Class 43.2 allows a 100% write-off of eligible clean energy equipment in the year of acquisition. For a $200,000 commercial solar system, Class 43.2 generates a $200,000 deduction in year one — reducing taxable income by the full equipment cost. At a 26.5% combined federal/Ontario corporate tax rate, this deduction generates approximately $53,000 in tax savings in year one alone. Combined with the 30% ITC, first-year tax benefits can offset 50–60% of total system cost.
What commercial solar financing does Solar X offer in Ontario?+
Solar X works with commercial financing partners to offer Ontario businesses: fixed-rate commercial solar loans (5–20 year terms, rates from 6–9%), equipment leasing (operational expense treatment, off-balance-sheet options), PPA structures for businesses that prefer zero upfront cost, and CMHC Green Home / BDC clean energy loan referrals. Solar X presents all available options with a full first-year financial model before any commitment.
What is the ROI timeline for commercial solar in Ontario?+
Commercial solar in Ontario typically achieves payback in 3–7 years depending on system size, financing structure, and electricity consumption. After the 30% ITC and Class 43.2 CCA, first-year net cost is often 45–55% of gross installation cost. Annual electricity savings then service the loan while generating positive cash flow. A 500 kW commercial system at $750,000 gross cost may net out at $375,000 after first-year tax benefits, with $80,000–$120,000 in annual electricity savings.
Can a commercial solar system be added to a business's balance sheet?+
Yes. Owned commercial solar systems (purchased or loan-financed) are capitalized as fixed assets on the balance sheet. This allows the business to claim Class 43.2 CCA depreciation and the federal ITC. Leased systems may be treated as operating expenses (off-balance-sheet) depending on lease structure — Solar X's financing partners offer both options. PPAs are typically off-balance-sheet as the developer owns the system.
