Your electricity use defines the problem
A system sized only from roof area can create production that does not match household needs. Annual use and future loads matter.
HOMES · OTTAWA
Residential solar in Ottawa without hidden assumptions.
Useful system size depends on the electricity bill, roof and what the household actually wants to power.
For an Ottawa home, we start with 12 months of electricity use, the roof and electrical service. The goal is to show expected production, constraints and rebate conditions before a commitment.

What we verify

Protect the roof as an asset
Roof age, shade, slope, orientation, structure and safe access should be reviewed before finalizing the array.

Storage solves a different problem
A battery can support critical loads or shift solar into the evening. It should not be added automatically to every proposal.
PROGRAM AND UTILITY
Ottawa : Hydro Ottawa
Hydro Ottawa net metering can credit eligible renewable generation exported to the grid. Credits are non-cash, grid capacity and approvals matter, and any remaining credit expires 12 months after it was created.
- The City of Ottawa publishes building-permit submission requirements for solar collectors on low-rise residential buildings. Electrical Safety Authority and Hydro Ottawa connection requirements are separate from the municipal permit.
- Rules and amounts are confirmed before equipment is ordered.
- Production and financial assumptions remain visible.

Frequently asked questions
Frequently asked questions
Should the roof be replaced first?
It depends on condition and remaining life. Compare the roof’s expected life with the solar system’s service life.
Can a battery be added later?
Often yes when the electrical architecture and inverter strategy anticipate that option.
Does the rebate cover roof work?
Program terms distinguish eligible energy measures from general roof work. Confirm the current official rules before contracting.
