Canadian Solar (CSIQ) is back in focus after its e-STORAGE unit signed a supply agreement with a major U.S. utility for a 500 MW, 2,493 MWh battery energy storage project tied to data centers.

The e-STORAGE deal lands at a time when Canadian Solar’s share price has a 7 day share price return of 5.93% but a 90 day share price return decline of 21.17%. The 1 year total shareholder return of 88.04% contrasts with a 5 year total shareholder return decline of 61.22%, which hints that recent momentum is softer than the longer term rebound investors have experienced.

With Canadian Solar trading at $18.39 and sitting at an 8.1% discount to an intrinsic value estimate and a 16.5% discount to analyst targets, you have to ask: is this a genuine opportunity, or is the market already pricing in future growth?

Most Popular Narrative: 21.2% Undervalued

With Canadian Solar last closing at $18.39 against a narrative fair value of $23.33, the most followed view sees meaningful upside embedded in the battery and storage story.

The company's forward integration into battery storage, with plans to expand BESS manufacturing capacity from 10 GWh to 24 GWh by 2026 and battery cell capacity from 3 GWh to 9 GWh, positions Canadian Solar to capture higher-margin business and increase average order value, positively impacting future net margins and earnings.

Want to see what kind of revenue runway and margin lift would need to materialise to back that fair value? The narrative leans on compound earnings growth, rising storage mix, and a future earnings multiple that sits well below many large chip names. Curious how those ingredients combine into a $23.33 figure instead of today’s $18 handle?

Result: Fair Value of $23.33 (UNDERVALUED)

However, this hinges on policy and trade conditions staying supportive, since higher tariffs or tighter U.S. rules could squeeze margins and slow storage project economics.
