What Are Solar Shares?

Solar power is the conversion of sunlight into electricity through a process known as the photoelectric effect. The most commonly used technique employs solar panels known as photovoltaics (PV).

Solar power is one of the fastest-growing renewable energy sources, with the installed solar PV capacity in Q3 2020 (in the USA) being sufficient to power up to 16.4 million homes. The momentum carried into 2021 as the outlook for this year looked favourable for an uptick in alternative energy demand.

Top 10 Solar Shares to Buy

As we present our list of the top ten solar shares, it’s worth noting that these companies come from all sorts of sectors such as industrial, energy, and utilities. Each stock’s value could therefore be affected by varying fundamental factors.

  1. Enphase Energy
  2. SolarEdge Technologies
  3. Canadian Solar
  4. First Solar
  5. Consolidated Edison
  6. Sunrun
  7. Brookfield Renewable Partners
  8. SolarWindow Technologies
  9. Sunnova Energy
  10. Daqo New Energy

1. Enphase Energy (NASDAQ: ENPH)

Enphase Energy is a technology company that develops home energy solutions based on solar power. It's the industry's top choice for microinverters, with 30 million solar inverters already delivered to customers around the world. This company’s revenues increased by 42.2% in Q3 2020 as the Biden presidency was expected to drive more growth in the solar sector.

Enphase Energy’s share price has surged in recent years, rising more than 200 times since 2017. This would have been a good penny stock purchase, and it might not be too late to get in on some of the action because the price fell back between January 2021 and May 2021 before beginning to rise again. Many investors make good money by buying shares on such dips.

2. SolarEdge Technologies (NASDAQ: SEDG)

SolarEdge Technologies is another solar inverter solutions company whose products cater to the residential market as well as commercial and small utility-scale installations. SolarEdge has solid finances, with over a billion dollars in cash. It is another company that was expected to benefit from the Biden administration.

The SolarEdge stock price soared in the two years to December 2020, which was no surprise since this company rose from being the 10th to the number one supplier of PV inverters. The share price falling back by around 30% between January and June 2021 may have presented an opportunity to buy on the dip.

3. Canadian Solar (CSIQ)

Canadian Solar manufactures solar cells, wafers, ingots, solar PV modules, solar power systems, and other solar products. It operates from multiple locations worldwide and has facilities in Canada, China, Indonesia, Vietnam, and Brazil.

Although Candian Solar shares are around four times higher in 2021 than they were in 2007, it’s been a rocky ride with the share price varying between $3 and $53 at various times. The year 2020 was a good year for Canadian Solar shares, and the share price dip (of about 27%) in the first six months of 2021 was consistent with other solar shares, thus possibly presenting an opportunity to buy on the dip.

4. First Solar (FSLR)

First Solar is a utility-scale PV power plant provider and a manufacturer of photovoltaic modules. It is the largest solar panel maker in the US but also services clients internationally. This year, First Solar sold the majority of its solar projects to wind developer Leeward Renewable Energy, to concentrate on manufacturing instead.

In the third quarter of 2020, First Solar reported an EPS of $1.45. Its stock price enjoyed a strong rally, jumping from the March low of $28.47 to $109.09 in December. By June 2021, the price has fallen back, thus presenting a possible buying opportunity.

5. Consolidated Edison (NYSE: ED)

Consolidated Edison is the second-largest solar energy producer in North America and ranks seventh in the world. It generated $12.5 billion in revenue in 2019.

The shares have trended steadily upwards since as far back as 1985 with a few pullbacks along the way. The most recent pullback in 2020/21 could be a good time to buy if you think the long-term uptrend will resume.

Expert Tip on Investing in Solar Shares

While shares in solar companies can be cyclical and subject to government policy changes, the one-way journey from fossil fuels to renewable energy sources might convince you that it’s a good idea to build stakes in these companies whenever their share prices dip.

Why Invest In Solar Shares?

According to the US Energy Information Administration (EIA), renewable energy sources generated 17% of US electricity in 2019. Solar power accounted for 2% of that figure, which was a 0.5% increase at a time when production of energy from all other alternative sources fell.

Investing in solar shares could give you a foothold into what could potentially be the leading energy source of the future.
