Written summary
Canadian Solar is a Canadian manufacturer headquartered in Guelph, Ontario, operating for more than two decades with a global production footprint concentrated largely in China and Southeast Asia. Listed on Nasdaq since 2006, the company appears on the S&P Global Tier 1 Cleantech Companies list and reports module manufacturing capacity in the range of 50-60 GW per year, having shipped close to 177 GW of panels cumulatively over its history. LG, by contrast, fully exited solar panel manufacturing in 2022, closing its Huntsville, Alabama facility amid rising material costs and pricing pressure from lower-cost Asian producers - the company still honors warranties on previously sold panels but no longer offers new products. On institutional footprint, Canadian Solar clearly leads, since it continues to actively expand and certify its portfolio while LG is now a legacy brand in this category.
Canadian Solar's current lineup spans TOPCon modules (TOPHiKu and TOPBiHiKu series, efficiency up to roughly 24.4 percent) and heterojunction HJT cells (HiHero series, bifaciality up to 95 percent), letting it serve residential and commercial rooftops as well as utility-scale ground-mount projects. LG's panels, though no longer sold, were historically well regarded in the residential segment for build quality and N-type NeON cell technology, but today they are relevant mainly to owners of existing systems seeking warranty service or system expansion.
For a buyer evaluating a new installation today, the choice is effectively decided by availability - Canadian Solar is a bankable, actively supported option with a current product catalog, while LG is no longer a viable source for new panels. The two brands are not interchangeable for new purchases; LG's relevance is now limited to legacy installations already in the field.
