With an energy efficiency of 22.7%, making it just a little less efficient than the most efficient brand from the same brand, the Maxeon. [pdf]
The location and orientation of solar panels affects their efficiency. For example, south-facing panels (in the northern hemisphere) will capture more sunlight and therefore be more efficient. The best solar panels are tilted. This makes them perpendicular to the sun’s rays, which also makes them more efficient.
The best solar panel on the market at the moment in terms of efficiency is the Maxeon 7, which is 24.1% efficient. The chart below is based on a report from the US government-funded National Renewable Energy Laboratory, who have recorded all major breakthroughs in solar cell efficiency since the mid-1970s.
Solar panel efficiency tends to range between 13% to 25% but can be as high as 40% or 50% for some high-end and experimental systems. This guide explains what solar panels and cells are, what makes them more or less efficient, and some of the different types of solar panels on the market. What Are Solar Panels and Solar Cells?
Solar panels are only around 20% efficient because of the inherent limitations of silicon-based technology. Factors like heat loss, reflection, and the inability to capture all wavelengths of sunlight reduce the conversion of sunlight into electricity.
Solar Panel Efficiency explained. Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 23%.
The efficiency of a solar panel is affected by numerous factors. Some solar cell types are inherently more efficient than others. Construction techniques and the materials used also have an impact on the efficiency of a solar panel. The location and orientation of solar panels affects their efficiency.

We began our search for the best solar power stocks by compiling a list of 25 public companies that are major players in the solar industry. This included companies that have a business model primarily focused on solar power, and ones that dealt with solar. [pdf]
This compensation may impact how and where listings appear. Investopedia does not include all offers available in the marketplace. The top solar stocks include Daqo New Energy for best value, Altus Power for fastest growth, and Enlight Renewable Energy for most momentum.
The industry's technological advancements and decreasing production costs make solar energy increasingly competitive against conventional energy sources. In addition, government incentives, supportive policies and increasing consumer demand for sustainable energy further drive the growth prospects of solar energy stocks.
To skip the detailed overview of the solar industry, go directly to the 5 Most Promising Solar Stocks According to Analysts. Solar energy stocks took a beating in 2023. Global X Solar ETF (RAYS) and Invesco Solar ETF (TAN) are down 41.38% and 29.83% for the year, respectively.
Cory has been a professional trader for two decades. In addition to trading and investing he's widely published and coaches individual clients on the finer points of gaining an edge in the market. The best stocks set to capitalize on the solar energy boom, should bullish predictions around the sector come to fruition.
The high-interest rate environment made a bearish case for solar stocks throughout the year due to a demand drop among retail customers. Moreover, California’s Net Energy Metering 3.0 policy has reduced incentives for rooftop solar owners drastically.
And considering FSLR was founded way back in 1999, this is a company with deep roots as well as a bright future if and when the solar sector takes off. Enphase Energy is among the largest solar stocks by several measures, with a market value more than double some of its peers and annual revenue that will top $1.4 billion this fiscal year.
