Chris Lau, Kapitall: Solar stocks lost some of their shine after a huge year. Are they poised for a turnaround? The solar energy sector is diverging negatively from the general markets. Solar stocks are down in recent days, led by a report of quarterly losses and a plant closure by ReneSola (SOL). Last year, excess supply for solar panels and weak pricing hurt stocks. In 2013, solar stocks reversed for the opposite reasons: prices are holding, and are expected to rise in 2014 – 2015.

Trina has 557.8 million in cash and cash equivalents. Looking beyond, Trina believes module revenue will grow to 15% of its total. After 2015, that portion could be 25%. Growing module sales should improve the steady growth potential. Canadian Solar has the highest average selling price, beating even Chinese solar companies. The firm continues to execute on sales. In 2014, gross margins could rise as the company boosts sales. In its third quarter report, Canadian Solar achieved gross margin of 20.4% on net income of $27.7 million. The company shipped 478 megawatts in the quarter, which exceeded its shipment guidance between 410 to 430 megawatts.
