Commercial Solar Ontario | $0 Upfront Solar PPA & Roof Leases

Standard Solar installs commercial rooftop solar across Ontario at zero upfront cost. Through a Power Purchase Agreement (PPA) or rooftop lease, Standard Solar handles everything — design, installation, maintenance — and you simply pay less for electricity than you do today.

Standard Solar simply puts money back into your pocket.

We pay landlords for the space and cut costs for owner-operators — value shared across everyone in the building. As Ontario electricity prices keep climbing, the gap between what you pay and what you could pay just keeps growing.

Proven technology. Proven team.

Solar modules have been a proven technology for decades. No moving parts, industry-leading warranties, full monitoring and insurance included. We are owners and operators — our installation and service partners are experienced, certified professionals who work within all Ontario rules and regulations.

For Property Owners: Monetize Your Rooftop with a Solar Lease

You own the building. Tenants operate inside it. Both structures below work together — they are both part of the arrangement. The Rooftop Lease is your agreement with us: we lease your roof and pay you income. The Solar Agreement is our direct agreement with your tenants: they buy electricity from us at a significant discount off the utility rate.

Passive income

Standard Solar leases your rooftop and pays you an annual lease fee — escalating over the term.

We handle everything

Engineering, installation, insurance, roof maintenance, and full removal & replacement if needed — all on us.

Zero cost to you

No upfront investment. We finance, build, and operate the system. You simply grant us rooftop access.

End of term

You own the system — and all the electricity it generates — at no cost to you.

Contract terms are flexible. Roof replacement coverage available in certain cases.

End-to-end, handled.

Real questions, straight answers.

If yours isn't here, ask it on the form — we'll answer in plain English.

Is my roof actually suitable?+

Most flat or low-slope commercial roofs over about 35,000 sq ft are good candidates, but the answer depends on age, structural capacity, shading, and orientation. The free layout is a real engineering review — we'll tell you honestly if a building isn't a fit before either of us spends real time on it.
