Solar Market Outlook in Canada
The forecast is bright for the future of the solar energy sector in Canada. In particular, the year 2020 was a promising one for the Canadian solar energy market and it has built a solid foundation for more solar growth in 2021.
The Canadian Renewable Energy Association released a statement citing that the renewable energy market in Canada – not just solar – saw significant expansion in 2020 and it is looking to build on that momentum for 2021 moving forward. This was impressive considering the challenges that faced them in 2020 given the pandemic. For 2020, the total solar capacity reached 2,000 MW, giving Canada sufficient energy storage.
The consistent growth in the solar market is fueled by the increased corporate demand and the policies put in place by the government. Even with the disruptions of 2020, Canada was able to generate 70 MW of solar PV capacity. The three levels of government in Canada will work together to reduce carbon emissions and to facilitate growth in solar PV capacity.
Wind and solar combine to form the largest share in Canada’s renewable energy sector in terms of power generation.
Solar Energy Equipment Supply Capacity in Canada
Canada is one of the leaders in the manufacture of solar equipment. However, there are more available global and online suppliers to cope with the demand for solar components and accessories.

There are more than 500 seaport facilities in Canada. However, the major seaports serving trade and logistics activity include
- Port of Vancouver,
- Port of Halifax,
- Port of Montreal,
- Port of Prince Rupert,
- Port of St. John.
Wholesale Disconnects for Solar Systems
Essentially, safety disconnects allow users to rapidly shut down the system in case of an emergency. For this reason, disconnect switches are required to comply with electrical codes and pass inspection.
A solar PV system usually has two safety disconnects. The first is the PV disconnect (or array DC disconnect). This kind of disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter.
The second disconnect is the AC disconnect. The AC disconnect is used to separate the inverter from the electrical grid. In a solar system, the AC disconnect is typically mounted to the wall between the inverter and utility meter. This kind of disconnect may be a breaker on a service panel, or it may be a standalone switch. Additionally, it is sized based on the output current of the inverter.
How to Size an AC or DC Disconnect?
Generally speaking, sizing refers to equipment, components, and connectivity (wiring) throughout a solar system as it relates to NEC requirements. The following terms are used to determine component output:
- Circuit load
- Amps or breaker size
- Wiring or cables
- Sizing and Protection of the AC Disconnect
NEC 690.10 stipulates that the circuit conductors between the inverter output and the building or structure disconnecting means shall be sized based on the output rating of the inverter. These conductors shall be protected from overcurrents in accordance with Article 240. The overcurrent protection shall be located at the output of the inverter.
Important Features to Look For in Disconnect in Bulk?
Disconnects are incredibly useful for solar systems, and so, it is important to get the best possible disconnect for your own solar system. The following are the core features to look for in a disconnect:
- Offers bi-directional functionality, which breaks the arc regardless of normal or a reverse current flow
- Includes all required components to meet NEC 690 requirements, including jumpers and labels
- Guards against accidental contact with live parts with clear polycarbonate dead fronts
- Available with modifications that allow customization to meet any application need
- Sizing of Module Interconnection Conductors and DC Overcurrent Protection
According to NEC 690.80, where a single overcurrent device is used to protect a set of two or more parallel-connected module circuits, the ampacity of each of the module interconnection conductors shall not be less than the sum of the rating of the single fuse plus 125% of the short-circuit current from the other parallel-connected modules.
