## Summary

Canadian Solar is a solar module manufacturer founded in 2001 by Dr. Shawn Qu in Guelph, Ontario, Canada. The company has been publicly traded on NASDAQ since 2006 and has grown into one of the five largest solar panel manufacturers in the world. BloombergNEF Tier 1 data places its annual module production capacity at approximately 61 GW, and the company was named to S&P Global Commodity Insights' Premier List of Tier 1 Cleantech Companies in 2025. SolarReviews awarded it the title of top solar panel brand of 2025. Growatt, by contrast, was founded in 2011 and is headquartered in Shenzhen, China. It is not primarily a solar panel manufacturer: its core business is inverters and energy storage, and it holds the position of world's leading residential inverter supplier. Canadian Solar holds a substantially stronger footprint as a bankable, institutional-grade panel manufacturer.

Canadian Solar's current panel lineup is built around the HiKu and TOPHiKu series. The TOPHiKu6 employs N-type TOPCon cell technology, while the TOPBiHiKu6 adds a bifacial design suited to commercial and utility-scale ground-mount projects. These product lines cover the full range from residential rooftops to large-scale generation assets. Growatt's relevance to a panel purchasing decision is more limited: the company's primary product families are its string inverters, hybrid inverters, and modular battery systems such as the APX HV - the last of which won a Solar Power World Top Products award in 2025. Growatt panels do appear in some markets as part of bundled system offerings, but the brand is not recognized as a panel manufacturer in the same sense as Canadian Solar.

For a buyer choosing solar panels, Canadian Solar is the direct and well-credentialed choice: Tier 1 bankability, a deep TOPCon product portfolio, and a long track record in project finance. Growatt is best evaluated on its inverter and storage merits rather than as a panel competitor - a complete installation might reasonably combine Canadian Solar modules with a Growatt hybrid inverter, as they serve different roles in the same system.
