CSIQ or ENPH: Which Solar Stock is Better Placed Right Now? (Revised)

Jewel Saha

Growing concerns relating to greenhouse gas emissions during electricity generation from fossil fuels have resulted in increasing usage of renewable and clean sources of energy. Utility operators are making fresh investments for setting up renewable energy-fired utility scale power plants.

The current U.S. Information Administration (“EIA”) report indicates that renewable energy resources such as solar and wind will be the fastest growing source of U.S. electricity generation for at least the next two years.

Solar is one of the fastest growing renewable energy sources in the United States and its contribution to total power generation surpassed contribution of biomass in 2017. At present, solar energy is the third largest renewable energy source, per EIA finding.

Against such a backdrop, in this article, we run a comparative analysis of two stocks belonging to the Zacks Solar industry— Canadian Solar Inc. CSIQ and Enphase Energy, Inc. ENPH — to ascertain which one performed better and is a suitable investment option right now.

Per EIA, the U.S. electric power sector plans to add more than 4 gigawatts (GW) of new solar capacity in 2019 and almost 6 GW in 2020, reflecting a total increase of 32% from the operational capacity at the end of 2018. Owing to this increase, solar energy is anticipated to contribute slightly more than 2% to total utility-scale generation in 2020.

Courtesy of ongoing research and development, the increasing conversion rate of solar panels and modules is making utility scale solar projects competitive compared with conventional energy sources. The tax credit from the U.S. government is assisting the utilities to develop large-scale solar plants.
