Community solar: shared solar projects in Canada

What is community solar?

A single array feeds the local grid, and the benefit is shared among participants. Depending on the program, you might hold a stake in the project, pay for a share of its output, or receive a credit on your electricity bill. People who rent, live in a condominium, have a shaded roof or cannot afford a full system are the usual target. Others simply prefer to back a local project.

The idea should not be confused with district heating. Our guide on solar community versus solar neighbourhood covers the heating side, and community solar heating versus rooftop solar compares the two approaches.

How do community solar programs work in Canada?

Rules differ by province because electricity is regulated at that level. Some provinces and utilities have run pilot or ongoing programs in which a developer or community group builds a project and local customers or organizations take part. Nova Scotia is one place where such programs have been set up. In others, there is nothing structured, and projects exist as one-off arrangements with a utility or a municipality.

Common models include:

• Subscription. You pay for a share of the output and receive a bill credit.
• Ownership. Members buy panels or units in the project and receive a return as it produces.
• Locally owned projects. A co-operative, First Nation or municipality owns the array and sells the power under a contract.

Whether credits carry over, expire or are paid out depends on the program. Compare it with the individual approach in net metering in Alberta, which lets one household offset its own use.

Who can take part, and what does it cost?

Eligibility rules vary. Some programs limit participation to customers of one utility, to a postal area, or to a particular type of organization such as a non-profit or a municipality. Others reserve capacity for low-income households or for Indigenous communities. There may be a waiting list.

On cost, there is no single figure. A subscription may need no upfront payment, while an ownership share can need a significant one. Compare any offer on the basis of what you pay, what you receive, for how long, and what happens if you move. The same discipline applies as for a home system, discussed in are solar panels worth it in Canada.

What are the risks and trade-offs?

Longer contracts, exit terms and the credit value are the things that most often catch people out. A project that underperforms pays less than promised, and some programs pay a fixed rate that may fall behind rising bills. Ask who carries the risk if the array fails or the developer goes out of business, and whether the contract transfers when you sell or leave your home.

A related question is ownership and metering when several parties share one system. Shared solar ownership and metering explains how that bookkeeping works. If a developer proposes a lease or a power purchase arrangement, read solar lease versus PPA first.

How do you find out what is available near you?

Start with your electricity utility, then your provincial energy ministry or regulator, then your municipality. The Government of Canada energy pages also list federal programs that may support community projects. Ask for the program rules in writing, including eligibility, the credit mechanism and the contract length. If nothing is on offer, rooftop solar or a different approach may fit better: see grid-tied versus off-grid solar for the basics.

At Drake Landing Solar Community in Okotoks, the sharing was of heat rather than electricity. Solar collectors on garage roofs fed a common loop that served all 52 homes, which is described on the district heating page.
