Power your home with energy from the sun

Lower your electricity bills, be more energy independent, and generate renewable electricity with a solar photovoltaic (PV) system using solar panels. 

If you're thinking about installing solar panels to power your home, we have information to help you decide.

Benefits

Here are a few of the benefits to installing solar in B.C.: 

1. Lower BC Hydro bills

By generating some of your own electricity with solar panels and participating in our self-generation program, you'll reduce your electricity bills by reducing the amount of electricity you need to buy from us. 

2. Energy self-sufficiency and flexibility 

Installing your own solar panel system gives you more energy independence. Generate your own electricity to power your home, but with the flexibility to rely on our grid if needed. Plus, you can easily monitor your home’s energy production.  

3. Potentially increase the value of your home

A private energy generation system is an attractive selling feature for home buyers looking for innovation, energy independence, and long-term savings. As long as it’s functional, efficient, and well designed, you have the opportunity to sell for higher than homes without it. 

4. It's environmentally conscious

Solar power is a renewable energy source and an environmentally conscious way to have private generation. In B.C., adding solar panels to your home doesn’t necessarily reduce your carbon footprint because the vast majority of power we generate is renewable hydroelectricity. But if you’re using solar power and battery storage to displace backup diesel generation during a power outage, you’re making a sustainable choice. 

Costs

The cost of installing a solar PV system for electricity generation has dropped dramatically in recent years, with an average cost of about $22,500 for a 7.5 kilowatt (kW) system. Technology has continually improved, and today’s more efficient systems yield a higher power output.

Available rebates 

As of July 23, 2024 residential customers can qualify for up to $5,000 in rebates for installing eligible solar panels and up to an additional $5,000 for eligible battery storage systems. You can get rebates for solar panels with or without a battery storage system, as long as you connect to our grid through our self-generation program.

How does a solar photovoltaic (PV) system work? 

Solar PV systems are comprised mainly of solar panels, inverters, breakers and mounting equipment. A solar panel generates power by converting sunlight to direct current electricity.

Inverters are then used to convert the direct current electricity into alternating current electricity to be used in your home.

How does a solar photovoltaic (PV) system work

How much power will a solar PV system generate in B.C.?

A typical solar PV installation on a residential roof is seven kilowatts (kW) in size with 16 solar panels, which in B.C., generates 7,700 kWh of electricity over a year.

The average household uses approximately 10,000 kWh per year, though this varies significantly based on a home's heating type, size and other factors. Log in to your online MyHydro account to understand your home's usage to see how a solar installation would support your electricity needs.

And long term, consider an industry average solar panel lifespan of about 25 years and an efficiency degradation rate of about 0.5% per year.

Types of solar PV systems

Grid-tied solar systems feed alternating current electricity directly to the local grid.

  • In B.C., a 1kW solar PV array would require about seven to eight square metres of south facing free space. A professional system installer can help you estimate the solar potential of your home.
  • Before installing a solar system on your home's roof, consider your roof's current condition and if rework is needed anytime in the near future.
  • Installing a solar PV system can be complicated, especially for roof-mounted systems. Solar panels are essentially made of glass and need to be handled with care. Mounting solar panels on your roof should be done by a roof system professional to ensure that no damage is done to the building's existing weather proofing.
  • Connecting a solar PV system to the grid requires complex electrical connections which need to be approved by BC Hydro. Hiring a professional solar PV system installer will help ensure that all necessary permits are obtained and that all safety measures are in place before the system is energized.

Off-grid solar systems store direct current electricity in batteries for later use. In B.C. they’re used in remote locations where there's no grid to tie into for power.

  • Off-grid systems are more expensive due to the added costs of the battery banks and charge controllers.
  • Battery banks are one of the highest lifecycle costs of an off-grid solar PV system as they require regular maintenance and/or replacement to ensure optimum system performance and longevity.
  • Depending on the type used, batteries have a lifespan of up to 10 years. Speak with a professional to understand battery options for your specific application.
  • Off-grid systems need to be sized appropriately to ensure that the battery banks are being used at maximum capacity throughout the year.
  • Consider hybrid solar PV/diesel generator systems for remote locations to ensure an adequately sized solar PV system and reliable power even during long periods of cloudy weather conditions.

Install and connect

Any grid-tied solar systems must be approved by BC Hydro before installation to ensure safety and effective operation. 

If you're interested in connecting a small (less than 100 kW) electricity generation system to our grid, learn more about the self-generation program for residential and commercial customers.

For systems larger than 100 kW, learn about distribution generator interconnections.
