Plenty of people live in condos and apartments and want solar. Most of them hit the same obstacle quickly. You own, or rent, the space inside your walls, and almost everything solar needs sits outside them. This article explains the usual barriers and the routes that sometimes work. It is general information, not legal advice. Condo law and building rules differ from province to province, so verify anything that matters.
Why condos are different
Solar panels need a roof, a wall or ground space, and an electrical connection. In a typical condo corporation, those belong to the corporation as common property. You may have exclusive use of a balcony or a parking spot, but the structure and the exterior are still usually governed by the declaration, the bylaws and the board.
Then there is the meter. In many buildings, each unit has its own meter, and a separate meter covers common areas such as hallways, elevators and parking. A system on the roof could serve either, and connecting it to individual suites is not simple. Utilities and regulators set the rules, and they vary. Our overview of net metering across Canada shows how much those rules differ even for single-family homes.
Route 1: a building-wide system
The most common approach is for the condo corporation to install solar for common-area use, such as lighting, ventilation and elevators. The corporation pays, the savings reduce common expenses, and every owner benefits through fees.
What this usually requires:
- A proposal, with a roof assessment and a structural check.
- Quotes from qualified installers.
- Board approval, and possibly an owner vote depending on cost and bylaws.
- Utility approval and a permit. See the interconnection process for how that normally works.
- Insurance review for the corporation.
It takes patience. Boards worry about roof warranties, long-term maintenance, special assessments and how to share the cost fairly. If you want to push this forward, a short, factual presentation with several quotes tends to land better than enthusiasm alone. A reserve fund study may show when the roof is due for replacement, which is a natural moment to consider panels.
Route 2: financing through a third party
Some buildings explore leases or power purchase agreements so the corporation does not pay upfront. These can carry long terms and obligations that bind the corporation and future owners, so they need careful legal review. Our explainer on solar leases and power purchase agreements covers the questions to ask. Do not sign or vote on anything binding without independent legal advice.
Route 3: shared or community arrangements
In some places, utilities and regulators have allowed or piloted ways of sharing the output of one system across several customers. Availability is patchy and changes, and the details of crediting each unit are specific to the programme. Ask your utility whether any such arrangement exists in your area, and check any claims you read online against the utility’s own information.
Route 4: small balcony or window devices
You may have seen compact plug-in solar kits sold in some countries. In Canada, connecting a device to a household outlet and feeding power back raises electrical code, utility and safety questions. Rules for such devices are not the same as in Europe, and what is allowed at the time of writing may change. Please check with your provincial electrical safety authority and your utility, and get written permission from the board, before buying anything. Stand-alone, non-grid-connected setups, such as a small panel charging a battery for portable use, are a different category and generally face fewer rules. Even then, balcony mounting may need consent.
Route 5: green electricity and other options
If you cannot host panels, you may be able to support renewable generation another way. Some utilities and retailers offer green electricity products. These are not the same as owning solar and do not give you production credits. Compare terms carefully and check what you are actually buying, including whether prices differ from the standard rate.
You can also lower your energy use through efficiency. A home energy audit is useful for owners, and some of the steps, such as lighting and appliance upgrades, are within a single unit’s control.
Townhouses and low-rise condos
Not all condos behave alike. In a freehold or common element townhouse, you might own the roof above your unit or have more control over it. Check your title and your declaration. Sometimes owners of individual units can install panels with board consent and an agreement covering roof repairs, insurance and removal if the roof needs work.
| Property type | Typical position |
|---|---|
| High-rise condo | Roof is common property; building-wide project is the main route |
| Low-rise condo | Similar, with a smaller roof and fewer owners to persuade |
| Townhouse condo | May allow unit-level systems with approval, depends on declaration |
| Freehold townhouse | Often treated like a house; check local rules |
Questions to put to the board
- Does the declaration or any bylaw address solar, antennas or exterior changes?
- Who would pay for roof repair or removal if panels sit on it?
- How would insurance change?
- Which meter would the system connect to?
- What would happen to the arrangement when a unit sells?

Quick answers
Can I put solar panels on my condo balcony?
Sometimes, but it depends on your bylaws, the building's rules and electrical regulations for grid-connected devices. Ask the board in writing before buying anything.
Who owns the roof in a condo building?
Usually the corporation, as common property. That means a board decision, and sometimes an owner vote, is needed for any roof installation.
Can condo owners share solar power?
Some arrangements exist or have been proposed, but metering rules vary by province and utility. Check with your utility and a lawyer.
