Manitoba ranks second among Canadian provinces for solar resource potential, with Winnipeg and southern Manitoba averaging 4.3 to 5.2 peak sun hours per day. A south-facing residential system in Winnipeg generates approximately 1,250 to 1,350 kWh per installed kW annually — comparable to Alberta and better than Ontario. Despite this strong solar resource, Manitoba’s solar market has grown more slowly than neighbouring provinces, partly because Manitoba Hydro’s net billing program pays a below-retail rate for exports and partly because Manitoba’s historically low electricity rates reduce the financial incentive to self-generate.
This guide covers Manitoba Hydro’s net billing program, the interconnection process, electrical permitting in Winnipeg and across the province, contractor licensing under the Manitoba Electrical Code, the Efficiency Manitoba rebate, and the financial picture for Manitoba solar in 2026.
Net Billing, Not Net Metering — Exports Earn Less Than Half the Retail Rate
Manitoba Hydro’s program is net billing, not true net metering. Surplus exports are purchased at $0.04390 per kWh — roughly 40–45% of the residential retail rate of $0.10–$0.11 per kWh. Every kilowatt-hour consumed on-site avoids a purchase at retail. Every kilowatt-hour exported earns less than half that value. System sizing should prioritise self-consumption over export maximisation. A system that exports 40% of its generation loses significant economic value compared to one that consumes 90% on-site.
Manitoba Hydro Net Billing Program
Manitoba Hydro is a provincial Crown corporation and the sole electricity distributor in Manitoba. It operates the net billing program for all grid-connected solar PV systems up to 100 kW. Unlike Alberta’s competitive retail market or Ontario’s fragmented LDC structure, Manitoba has a single regulated utility — simplifying the application process but leaving no room for rate negotiation.
How Net Billing Works
Under Manitoba Hydro’s net billing program, electricity flows are measured separately:
- Consumption: Electricity imported from the grid is billed at the standard residential or commercial rate (~$0.10–$0.11 per kWh for residential customers on the standard rate)
- Generation: Solar electricity consumed on-site reduces the amount imported from the grid, saving the full retail rate
- Export: Surplus solar electricity exported to the grid is purchased by Manitoba Hydro at the excess energy price of $0.04390 per kWh
The excess energy price is updated annually on April 1 based on Manitoba Hydro’s avoided cost calculations. The current rate of $0.04390 per kWh has been in effect since April 2025.
Credit mechanism: Exported energy generates a monetary credit on the customer’s account. Credits are applied monthly against the bill. If credits exceed the bill in a given month, the surplus carries forward to future months. Unlike Ontario’s 12-month expiry, Manitoba Hydro credits do not have a fixed expiration period — they remain on the account until consumed.
System sizing implication: A typical Manitoba home consuming 10,000 kWh annually with an 8 kW solar system generating ~10,000 kWh/year would self-consume roughly 65–75% of generation (6,500–7,500 kWh) and export 25–35% (2,500–3,500 kWh). The on-site consumption avoids purchases at ~$0.105/kWh, worth ~$735/year. The exports earn $0.04390/kWh, worth ~$110/year. Self-consumed energy is worth more than six times as much per kWh as exported energy.

Interconnection and Technical Requirements
All grid-tied solar systems in Manitoba must meet Manitoba Hydro’s technical interconnection standards, which align with the Manitoba Electrical Code and CSA standards.
Inverter Requirements
- Inverters must be certified to CSA C22.2 No. 107.1 or equivalent UL standard
- Anti-islanding protection is mandatory
- Inverters must comply with IEEE 1547 or CSA C22.3 No. 9 interconnection standards
- Manitoba Hydro may require specific settings or additional protection for systems on constrained distribution feeders
Metering
Manitoba Hydro installs a bidirectional meter at no charge. The meter records energy imported and exported separately. Customers do not provide their own metering equipment. Meter installation is typically scheduled within 2–4 weeks of receiving the inspection certificate.
Protection and Safety
- AC disconnect switch must be readily accessible and lockable
- DC disconnect required at the array per Manitoba Electrical Code Section 64
- Grounding and bonding must comply with code requirements
- All labelling must meet Manitoba Electrical Code specifications
- Rapid shutdown or equivalent safety measures required for rooftop systems
Licensing and Permitting in Manitoba
Electrical Contractor Licensing
Manitoba requires all electrical work for solar PV installations to be performed by a licensed electrical contractor. The licensing framework is administered by the Manitoba Department of Labour and Immigration.
Requirements for solar installation:
- Contractor must hold a valid Manitoba electrical contractor licence
- A Master Electrician must be associated with the contractor
- Journeyperson electricians may perform installation work under Master Electrician supervision
- Contractor must carry liability insurance
Homeowners cannot perform regulated electrical work on grid-tied solar systems. Self-installation prevents Manitoba Hydro interconnection and voids insurance.
Electrical Permits
An electrical permit is mandatory before any solar installation work begins. Permits are issued by:
- Office of the Fire Commissioner (Electrical Inspection Section) for most of Manitoba
- City of Winnipeg Electrical Inspection Department for properties within Winnipeg city limits
The permit application requires:
- Single-line diagram of the PV system
- Equipment specifications (modules, inverter, disconnects)
- Site plan showing array and inverter locations
- Proof of contractor licence
Permit fees vary by jurisdiction. Typical residential solar permit fees range from $150 to $350.
Building Permits
Winnipeg: The City of Winnipeg requires a building permit for rooftop solar installations. The permit ensures the roof structure can support the additional dead load of the solar array plus snow and wind loads. Apply through the City’s Planning, Property and Development Department. Processing typically takes 2–4 weeks.
Rural areas: Building permit requirements vary by municipality. Some rural municipalities do not require building permits for rooftop solar on existing residential buildings. Ground-mounted systems more commonly require permits. Contact the local municipal office before proceeding.
Efficiency Manitoba Solar Rebate
Efficiency Manitoba is the province’s energy efficiency utility, established to help Manitobans reduce energy consumption. It offers one of the more straightforward solar rebate programs in Canada.
Residential Rebate
- Rate: $0.50 per DC watt installed
- Maximum system size: 10 kW DC
- Maximum rebate: $5,000 per residential property
- Eligibility: Manitoba residential property owners with an active Manitoba Hydro account
- Equipment: Must be new, CSA-certified equipment installed by a licensed contractor
Commercial Rebate
- Rate: $0.50 per DC watt installed
- Maximum system size: No cap for systems under 100 kW (the net billing program cap)
- Pre-approval: Not required for systems under 100 kW
- Eligibility: Manitoba businesses with an active Manitoba Hydro commercial account
Application Process
- Confirm eligibility through efficiencymanitoba.ca
- For residential customers: apply for pre-approval before installation
- Install the system using a licensed contractor
- Submit proof of installation, equipment invoices, and contractor details
- Efficiency Manitoba processes the rebate within 30–45 business days
The Efficiency Manitoba rebate can be combined with Manitoba Hydro net billing. It can also be combined with the federal Clean Technology Investment Tax Credit for business customers. However, the rebate amount reduces the eligible cost base for the federal ITC — consult a tax advisor.
Step-by-Step: Going Solar in Manitoba
Assess site and size the system for maximum self-consumption
Manitoba’s strong solar resource (1,250–1,350 kWh/kWp/year in Winnipeg) supports solid generation, but the net billing export rate of $0.04390/kWh means self-consumed energy is worth more than twice as much as exported energy. Size the system to match or slightly undershoot annual consumption. Use solar design software with Manitoba-specific irradiance data and load profiling to optimise the self-consumption ratio before finalising the design.
Apply for the Efficiency Manitoba solar rebate
Residential customers should apply for pre-approval through efficiencymanitoba.ca before installation. The rebate is $0.50 per DC watt, capped at $5,000. Commercial customers do not need pre-approval for systems under 100 kW. Gather system specifications, contractor details, and property information for the application. The rebate typically pays out within 30–45 days after installation documentation is submitted.
Engage a licensed Manitoba electrical contractor
Verify the contractor holds a valid Manitoba electrical contractor licence and employs a Master Electrician. Check licence status through the Manitoba Department of Labour and Immigration. Confirm the contractor has experience with grid-tied solar and understands Manitoba Hydro’s interconnection requirements. Obtain a written contract specifying scope, timeline, warranty, and permit responsibility.
Apply for electrical and building permits
The contractor applies for an electrical permit through the Office of the Fire Commissioner or the City of Winnipeg’s electrical inspection department. In Winnipeg, also apply for a building permit through the City’s Planning, Property and Development Department. Rural properties should contact the local municipality for building permit requirements. Submit complete documentation: single-line diagram, equipment specs, site plan, and structural details. Do not begin installation until all permits are issued.
Submit the Manitoba Hydro net billing application
Complete the Manitoba Hydro net billing application with system specifications, inverter model and certification, site plan, and contractor details. Submit to Manitoba Hydro Customer Service. Wait for written approval before beginning installation. Typical processing is 2–4 weeks. The approval confirms technical compliance and schedules the bidirectional meter installation.
Install, inspect, and receive permission to operate
The licensed contractor installs the system per the Manitoba Electrical Code. After completion, request an electrical inspection. The inspector verifies inverter certification, wiring, grounding, bonding, labelling, and code compliance. Once the inspection passes, submit the certificate to Manitoba Hydro. Manitoba Hydro installs the bidirectional meter at no charge and issues written permission to operate. The system can then export surplus electricity and earn credits at $0.04390/kWh.

Permitting Across Manitoba
Winnipeg
Winnipeg is Manitoba’s largest city and has a well-defined permitting process for solar installations.
- Electrical permit: Required. Issued by the City of Winnipeg Electrical Inspection Department. The licensed contractor must apply.
- Building permit: Required for rooftop solar. The City verifies structural adequacy for the added loads.
- Processing time: 2–4 weeks for both permits combined.
- Contact: City of Winnipeg Planning, Property and Development Department
Rural and Smaller Communities
Outside Winnipeg, electrical permits are issued by the Office of the Fire Commissioner (Electrical Inspection Section). Building permit requirements vary by municipality:
- Some rural municipalities do not require building permits for rooftop solar on existing buildings
- Ground-mounted systems more commonly require permits
- Always contact the local municipal office before proceeding
The Office of the Fire Commissioner covers the entire province for electrical inspections and can schedule inspections in rural areas.
Financial Picture for Manitoba Solar
Efficiency Manitoba Rebate
The Efficiency Manitoba rebate of $0.50 per DC watt (up to $5,000 residential) is the primary provincial incentive. For a typical 8 kW residential system, this equals $4,000 — a meaningful reduction in upfront cost.
Federal Incentives
Clean Technology Investment Tax Credit: Businesses and farms can claim a 30% refundable tax credit on eligible solar PV capital costs through December 31, 2033. This applies to taxable Canadian corporations. The rebate amount from Efficiency Manitoba reduces the eligible cost base for the ITC.
Canada Greener Homes Programs: Both the grant and loan programs are closed to new applications.
Manitoba’s Low Electricity Rates
Manitoba has among the lowest residential electricity rates in Canada — approximately $0.10–$0.11 per kWh. While this is good for consumers, it also extends the payback period for solar investments because each kilowatt-hour of avoided consumption saves less than in provinces with higher rates.
Typical Financial Profile: 8 kW Manitoba Residential System
| Item | Value |
|---|---|
| Annual generation (Winnipeg, south-facing) | ~10,400 kWh |
| System cost installed (2026) | $20,000–$26,000 |
| Efficiency Manitoba rebate | ~$4,000 (8 kW × $0.50/W) |
| Net cost after rebate | $16,000–$22,000 |
| Self-consumed portion (est.) | ~70% (7,300 kWh) |
| Exported portion (est.) | ~30% (3,100 kWh) |
| Value of self-consumed energy | ~$770/year |
| Value of exported energy ($0.04390/kWh) | ~$136/year |
| Total annual savings | ~$906/year |
| Simple payback | 18–24 years |
The payback period is longer than in provinces with higher electricity rates or full retail-rate net metering. However, the Efficiency Manitoba rebate improves economics meaningfully. For customers with high daytime consumption (retirees, home-based businesses), the self-consumption ratio can reach 80–85%, improving payback by several years.
Use generation and financial modelling to calculate precise payback for specific Manitoba addresses, consumption profiles, and system sizes.
Common Compliance Issues in Manitoba
| Issue | Consequence | Fix |
|---|---|---|
| System oversized for export | Poor payback — exports earn only $0.04390/kWh | Size to match consumption; model self-consumption ratio before finalising |
| Unlicensed contractor | Illegal; inspection failure; no interconnection | Verify contractor licence through Manitoba Department of Labour and Immigration |
| Missing Efficiency Manitoba pre-approval (residential) | Rebate denied; customer pays full cost | Apply for pre-approval before installation begins |
| Starting installation before permits | Work stoppage; fines; insurance issues | Wait for all permits before beginning work |
| Non-certified inverter | Inspection failure; Manitoba Hydro rejects interconnection | Verify CSA or UL certification on all inverters |
| Missing building permit in Winnipeg | City can order removal; project delay | Apply for building permit with electrical permit |
| Not submitting Manitoba Hydro application early | Delayed meter installation | Submit net billing application before installation |
| Claiming federal ITC without deducting Efficiency Manitoba rebate | CRA audit risk | Reduce eligible cost base by rebate amount |

Frequently Asked Questions
What is the difference between net billing and net metering in Manitoba?
Manitoba Hydro operates net billing, not true net metering. Under net billing, surplus exports are purchased at $0.04390 per kWh — the excess energy price. Under true net metering, exports would be credited at the full retail rate of ~$0.10–$0.11 per kWh. The export rate is roughly 40–45% of retail. Credits are monetary and applied to the customer’s account.
What is the maximum solar system size for Manitoba Hydro net billing?
Manitoba Hydro caps net billing systems at 100 kW nameplate capacity for residential, commercial, and agricultural customers. Most residential systems range from 5 kW to 12 kW.
Does Manitoba offer any solar rebates or incentives?
Yes. Efficiency Manitoba offers $0.50 per DC watt, up to 10 kW and $5,000 per residential property. Commercial customers receive $0.50 per DC watt with no pre-approval for systems under 100 kW. Businesses can also claim the federal Clean Technology Investment Tax Credit (30% refundable).
Do I need a permit to install solar in Manitoba?
Yes. An electrical permit is mandatory, issued by the Office of the Fire Commissioner or the City of Winnipeg’s electrical inspection department. Winnipeg also requires a building permit for rooftop solar. Only a licensed electrical contractor can pull an electrical permit.
Can I install solar myself in Manitoba?
No. All regulated electrical work must be performed by a licensed electrical contractor employing a Master Electrician. Self-installation is illegal for grid-tied systems and prevents Manitoba Hydro interconnection.
