Can You Sell Solar Energy Back to the Power Company in Canada? Net Metering

1. Understanding Solar Energy in Canada

What is Solar Energy and How is It Generated?

Solar energy is power from the sun converted into electricity through photovoltaic (PV) panels. When sunlight hits the panels, it creates an electrical current. The energy is either used directly or sent to the grid. This simple process produces no pollution and uses an abundant resource.

How Prevalent is Solar Energy Adoption in Canada?

• Solar installations are on the rise across the country.
• Many provinces are seeing double-digit percentage increases in residential solar adoption.
• Investment in solar is growing, driven by falling equipment costs and supportive policies.

Why Do Homeowners and Businesses Invest in Solar Power?

• Energy Cost Savings: Solar panels cut down on the electricity you buy from the grid.
• Return on Investment: Over time, the credits and savings can cover the cost of installation.
• Energy Independence: Rely less on the utility and protect yourself against price hikes.
• Environmental Impact: Reduce your carbon footprint and support local renewable energy production.

2. The Process of Selling Solar Energy Back to the Grid

What is Net Metering and How Does It Work?

Net metering lets your solar system interact with the grid. Here’s how it works:

• Your solar panels produce power.
• You use what you need at home.
• Extra power flows into the grid.
• Your utility records this surplus and credits your bill accordingly.

The key is that every kilowatt-hour (kWh) you produce lowers the amount you need to buy. Some provinces offer a full retail rate credit for your exported energy, while others provide a fixed buyback rate.

Basic Steps to Connect a Solar Energy System to the Grid

• System Installation: A qualified installer sets up your panels and wiring.
• Interconnection Application: You apply to your local utility to connect your system.
• Meter Installation: A bi-directional meter is installed to measure energy flowing both ways.
• Approval and Operation: Once approved, your system starts generating credits when you send excess energy to the grid.

How Do Energy Credits Work in Different Provinces?

• Full Retail Rate Credits: In some regions, every kWh exported offsets a kWh consumed.
• Fixed Buyback Rates: Other areas pay a set rate (e.g., 7.5¢ per kWh in Saskatchewan) for surplus energy.
• Credit Carryover: In many cases, unused credits can roll over to the next month. Some provinces have limits, such as a 12-month cap.

Cash Payments vs. Bill Credits

Most programs provide bill credits instead of direct cash payments. With a credit system, you see a reduction in your monthly bill rather than receiving a check. Some provinces may offer cash payouts for any credits left at the end of a year, but this is less common.

3. Provincial Regulations and Incentives
