The Opportunity

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.

Cost & Return

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.

Who It's For

Commercial 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.
