Why invest in solar energy?

The U.S., the European Union, and Japan have pledged to be carbon neutral by 2050, and the shift to renewable sources of energy like solar is a must. Solar energy emits no greenhouse gases, and sunshine is plentiful in many places, making solar the cheapest form of electricity globally, even without subsidies.

The fastest-growing renewable technology, solar energy provides only 3% of global electricity. So there is clearly room for growth. Helped by dropping costs, solar installations are booming. Solar energy is also benefiting from government regulations, tax credits, and corporate commitments to get to net-zero carbon. In 2021 alone, 183 GW of capacity was added globally; 2022 additions are expected to exceed 200 GW.

The main issue with solar is that the sun doesn’t shine all the time, so it can only generate electricity during the day. However, even this challenge is being solved with developments like better lithium-ion battery storage. Dropping battery costs would let customers bank solar power during the day and use it at night or even release it back into the grid.

In spite of these positive trends, solar stocks are volatile. The Invesco Solar ETF (TAN), the largest solar stock ETF, declined by 25% in 2021. Like many other industries, solar panel manufacturers are struggling with cost inflation and supply chain issues. The prices of key metals like steel and aluminum have gone up. There have been semiconductor shortages.

Some China-based manufacturers have also been hit when the U.S. government blocked solar panel shipments, alleging human rights abuses in the Xinjiang region, the heart of the Chinese solar industry.

However, these near-term challenges could mean it’s a good time to invest in the long-term trend.

The best solar energy stocks

There are several ways you can invest in solar:

1. Solar panel and component manufacturers

Photovoltaic cells in solar panels convert sunlight into energy. Companies like First Solar in the U.S. and JinkoSolar in China make the panels. Enphase Energy and SolarEdge design inverters, the “brains” of the solar panels. Xinyi Solar and Flat Glass Group make solar glass. And Daqo New Energy produces polysilicon, a material used to make solar wafers. However, most of the top solar panel manufacturers and component makers are based in China, and the stocks that are only listed in mainland China may be difficult for U.S.-based investors to access.

2. Solar panel installers

Residential or rooftop solar in the U.S. generates about 19 GW of power each year. Companies like SunnovaSunrun, and SunPower lease and sell solar panel systems and even provide battery storage. Demand for installations has increased in the aftermath of the wildfires in California and winter storms in Texas. 

3. Solar farms

Although anyone can install a solar panel on their roof and generate electricity, utilities build huge facilities, also known as solar farms. In the U.S., these utility-scale installations generate almost 17 GW of power. Although major renewable energy players like NextEra Energy operate solar farms, most of them are also big in wind, hydro, or natural gas. However, smaller companies like Atlantica Sustainable Infrastructure Plc are mostly tied to solar farms.
