40% Subsidy from Hydro-Québec
RBQ # : 5635193501
Hydro-Québec Subsidy for Solar Panels
| $1/watt ($1,000 per kW) |
Up to 40% (of the total amount) |
Maximum of $40,500.00 |
|---|
Net Metering Program
- Your electricity production reduces your consumption.
- No payment required. Any surplus energy is credited to your electricity bill.
- You have 24 months to use your surplus credits.
We therefore optimize your installation based on:
- Available space on your roof: 45 kW
- Your annual consumption: 61,889 kWh = 50 kW installation
Projected Electricity Rate Increases
4.8% per year from 2026 to 2028
-
Request submitted by Hydro-Québec. Decision expected in March 2026.
Hydro-Québec wants a 4.8% rate increase for SMEs and industries | Radio-Canada
Up to 8% per year possible
-
To offset the 3% cap in the residential sector, the increase in the commercial sector would need to reach 8%.

• Electrical diagram
• Preparation and submission of your permit application (Power of Attorney)
• Follow-up and coordination with the urban planning department
Step 3: Installation and Connection
• Electrical connection by a master electrician
• Start saving on electricity
• 60% payment by pre-authorized debit / Beginning of withdrawals
Step 4: Subsidy
• Follow-up and coordination with Hydro-Québec
• Payment of the final balance
Step 5: Monitoring and Performance Analysis of Your Installation*
• Free for the first year
• $260 per year thereafter (annual increase of $10)
• A telephone or internet line is required. Hydro-Québec must be able to shut down the system for safety purposes.
Appendix B: Performance Guarantee
(Legal review in progress)
In the event that the solar installation does not produce the estimated energy during a given year, as outlined in the table below, ESP commits to paying the client an amount equivalent to the difference.
This performance guarantee is subject to the following exclusions:
• Equipment damage or malfunction
• Poor maintenance or dirt accumulation from third parties (e.g., nearby factories)
• Addition of obstructions or modifications made without ESP’s prior consent
• Snow accumulation. ESP must be notified to clear snow
Payment Formula
• We guarantee kWh production, not future electricity rates
• Performance guarantee: 1,000 kWh per installed kW, decreasing by 0.5% per year
To be eligible for this guarantee, you must use the monitoring service provided by ESP énergie inc. and pay the associated fees. Monitoring service is free during the first year of commissioning, $260 + taxes annually thereafter, with an annual increase of $10.
Monitoring Service Requirements
• Site access within one business day upon ESP’s request
• Excludes maintenance or repair costs. The service monitors your installation but does not cover repair fees.

Appendix D: Impact of Snow on Production
Salaberry-de-Valleyfield (Southern Quebec) experiences moderate snowfall (~200 to 250 cm annually), similar to Montreal.
Studies on rooftop photovoltaic energy in Canada (sloped roofs, typical commercial inclinations ~10° to 30°):
- Annual snow loss — typically 2 to 6% of total production
- Higher (5 to 10%) for low-pitch / flatter roofs or very snowy years
- Lower (1 to 4%) for steeper inclinations (>35°–40°) where snow slides off faster
Suggested Monthly Distribution (to be added to baseline dirt losses)
| Month | Loss Due to Snow / Dirt (%) | Reason |
|---|---|---|
| January | 15 to 30 % | Possible heavy coverage; low sunlight duration minimizes impact |
| February | 10 to 25 % | Similar to January |
| March | 5 to 15 % | Snow melting begins |
| April | 0 to 5 % | Occasional late snow |
| May–October | 1 to 2 % | Dust only |
| November | 0 to 5 % | Possible early snow |
| December | 10 to 20 % | Increasing coverage |
