Start with ownership and contract status
The direct answer is that a Toronto home buyer should verify who owns the rooftop solar system, read every lease, loan or power contract, confirm municipal and electrical approvals, inspect the roof and equipment, and understand the Toronto Hydro arrangement before becoming firm. Panels can add useful on-site generation, but the legal and practical file matters as much as the hardware.
Ask the seller for the purchase invoice and proof of payment, or the complete lease, financing agreement, Power Purchase Agreement and Associated Equipment Agreement. Record the provider, term, payment schedule, escalation clauses, maintenance duties, insurance requirements, buyout amount, transfer procedure and removal obligations. Sam Kamra recommends treating an unclear ownership claim as an open closing item, not as a detail to resolve after possession.
Confirm permits, inspections and utility authorization
The City of Toronto says a building permit is required for rooftop or wall-mounted solar panels with an area greater than five square metres. Its permit guide calls for structural information showing how roof and solar loads reach the building walls, plus module, racking, inverter and attachment details. Request the permit, approved drawings, inspection record and any revision or deficiency correspondence. Have Toronto Building confirm the file when records are incomplete.
Solar electrical work must also meet Ontario electrical-safety requirements. Toronto's SolarTO guidance says a connection authorization must be obtained from the Electrical Safety Authority after inspection. Request the ESA notification or authorization documentation and match the address, system and contractor to the installed equipment. Also obtain the Toronto Hydro connection approval and net-metering agreement where applicable. Approval for a system at one property or under one arrangement should not be assumed to transfer automatically.
Review the roof and the complete equipment system
A qualified inspector should examine accessible roof covering, flashing, mounting penetrations, drainage, panel clearance, visible wiring, disconnects, inverter, labels and signs of leakage or movement. Ask the roofer and solar contractor how much service life remains in the roof, whether panels must be removed for future replacement, and who can perform that work without affecting warranties. Price removal, storage and reinstallation before treating an aging roof as a minor issue.
Create an equipment schedule listing panel and inverter models, serial numbers, installation date, rated capacity, monitoring access, batteries and warranties. Compare it with invoices, approved plans and current photographs. Request recent production reports, but do not treat a single sunny month or sales estimate as guaranteed future output. Shade, weather, equipment condition, orientation and household consumption all affect results. Sam Kamra's buyer guidance can help organize these questions, while additional GTA property resources support the wider inspection file.
Understand net metering and the closing handoff
Under Ontario net metering, eligible renewable generation serves the property first and excess electricity can flow to the grid for bill credits. The Ontario Energy Board says credits offset electricity-consumption charges and may be carried forward for up to 12 months; they are not cash income and do not offset every charge. Toronto Hydro requires an application, technical compliance and a net-metering agreement, and eligibility can depend on local connection capacity.
Ask Toronto Hydro and the contract provider what the buyer must do before or after closing. Identify account changes, meter or monitoring access, required forms, third-party consent and any deadline that could interrupt participation. Have the real-estate lawyer review title, purchase-agreement wording, payout statements and assignment documents, and specify whether the seller must discharge financing, obtain consent or complete a transfer. The Toronto fixtures and rental-equipment checklist supports this contract review.
Make the decision from a documented file
Keep the contracts, invoices, permits, approved drawings, ESA and utility records, inspection findings, warranties, production history, insurance response and closing documents together. Confirm whether the insurer needs system details and who is responsible for storm, fire, roof or equipment damage. If the system has a battery, ask qualified professionals about its approvals, location, ventilation, emergency procedures and warranty rather than assuming the panel documentation covers it.
CB Herald's discussion of Sam Kamra and public LTB data illustrates evidence-based property review, while Barchart's report on the RealEstateBuyer.ca launch covers Sam Kamra's broader property-services work. The conclusion is practical: verify ownership, approvals, condition, utility status and transfer terms. Take unanswered questions to the lawyer, insurer, Toronto Hydro and qualified solar, roofing and electrical professionals before waiving conditions.
Questions and answers
Toronto Rooftop Solar Panels FAQ
Does a Toronto rooftop solar system need a building permit?
The City of Toronto says rooftop or wall-mounted solar panels greater than five square metres require a building permit. Buyers should verify the permit, approved plans and final inspection record for the installed system.
What electrical approval should a solar buyer request?
Request the Electrical Safety Authority notification or connection-authorization documentation and confirm that it matches the property and installed system. Also verify the local utility connection approval.
Do Ontario net-metering credits get paid out as cash?
No. The Ontario Energy Board explains that credits offset eligible electricity-consumption charges on future bills. They do not offset every bill charge, and unused credits may be carried forward for up to 12 months.
Can a solar lease or financing contract transfer automatically to a buyer?
Do not assume so. The parties should review the complete agreement, provider consent, qualification requirements, transfer fees, buyout options and closing documents with the provider and real-estate lawyer.
What solar records should a Toronto home buyer request?
Request ownership and contract documents, invoices, permits, approved plans, inspection records, ESA and utility approvals, warranties, equipment details, monitoring access, production history, roof records and insurance information.
