While the renewable energy sector's tailwinds are undeniable, investors must weigh the risks of elevated leverage against the potential for long-term growth in a market projected to expand significantly through 2026 and beyond.

For now, Canadian Solar appears to be a high-conviction play for those who believe in the confluence of energy storage demand, policy support, and its ability to navigate near-term challenges.
