Ontario Electricity Costs Are Rising. Solar Costs Aren't.
The OEB's November 2025 rate increases hit commercial customers hardest. Solar panel costs have fallen. Incentive programs are at peak levels. The window is now.
How the Economics Work
Commercial solar in Ontario costs $1.50–$2.50 per watt installed. Two government programs — one provincial, one federal — cover a significant portion.
Example: 200 kW rooftop system on a GTA warehouse
Your building is different.
These numbers are for a 200 kW system. Your actual cost, incentive value, and payback depend on your roof, electricity consumption, utility provider, and building type.
Solenery's free energy audit estimates all of this — using satellite imagery, public data, and current incentive programs. You get your property profile, eligible incentives, and estimated savings in minutes.
Start Free Energy AuditCommercial Property Types
Solar works for any commercial roof in Ontario connected to a Local Distribution Company. These property types have the strongest economics.
Cold Storage & Refrigeration
Highest electricity intensity. Large flat roofs. Fastest payback — often under 4 years.
Warehouses & Distribution
Massive unobstructed rooftops. Ideal for large systems (200+ kW). Strong daytime load alignment.
Manufacturing Plants
High baseload consumption. Solar offsets expensive daytime demand charges.
Retail Plazas & Malls
Multi-tenant buildings. Shared infrastructure reduces common area electricity costs.
Office Buildings
HVAC and lighting loads align with solar production. ESG credibility for tenant attraction.
Industrial Parks
Portfolio approach across multiple buildings. Aggregated systems improve per-kW economics.
