Top 10 Most Efficient Solar Panels in 2022 |

Updated: Dec 4, 2021

You've done your research on the best panels and decided to prioritize efficiency. Smart decision. Smart move. Buying the most efficient panels will give you the most value for money when working with a limited roof space. It is often, but not always, the best option for homeowners.

Solar panel efficiency, also known as solar energy, is simply the conversion of sunlight onto the panels into energy. We'll explain what solar efficiency is and how to find the best solar panels for you home.

Understanding the Efficiency of Solar Panels

The efficiency of a solar panel is the ratio of the amount of sunlight that it receives to its surface. The highest efficiency solar panels available today are only 22.8% (thanks to Solar Power). This means that the panel converts approximately 22.8% of the sun’s irradiance into AC electricity.

Although this may seem like a small amount of money, the rapid advancements in solar technology have exceeded most people's expectations. Solar panels were only 15% efficient a decade ago. Only 2% was achieved by the first solar panels in the mid-1950s. We may soon see panels on the market that reach efficiency levels close to 50%.

Which are the most efficient solar panels available today?

Let's take a look now at the most efficient solar panels in 2022, given all of the recent advances in solar technology. These are the most efficient solar panels available at the time of publication based on our research:

The power refers to the panel's wattage output. The panel's power is determined by how much electricity it can produce. Power works with efficiency and not to determine it.

What is the Factor that Determines Solar Panel Efficiency

The composition of the solar panel's photovoltaic (PV), cell and the panel structure are two main factors that determine its efficiency. It is possible to wonder what distinguishes them.

Solar Cell Efficiency

A photovoltaic cell, which is the smallest unit in a solar panel, is usually made of silicon atoms. Photovoltaic effects, which are the processes by which sunlight turns into electricity, occurs in solar cells. Solar panels combine multiple cells to produce more power and allow the power to flow through homes.

The most efficient types are monocrystalline, rather than polycrystalline or thin film. This panel is made from one single silicon crystal. This makes the cells more efficient and less susceptible to sunlight.

You may have heard of N-type and P-type solar cell types in your research. While this won't be of much importance to most customers, it might matter to you if you are curious. The number of electrons these solar cells carry makes them different. N-type solar cells are negatively charged via phosphorus, while P-type solar cells are positively charged via boron. There are also multi-junction solar cell designs that can be made with either P- or N-type materials.

Solar Panel Efficiency

The overall panel efficiency is more dependent on the panel's structure. Even if your solar cells are the most efficient, it is still important to collect the electrons and then direct the current in the right direction. To avoid losing energy, a solar panel must be interconnected as smoothly as possible. This will impact the overall efficiency of the solar panel.

Why is Solar Panel Efficiency Important?

It would be unjust to compare the most efficient solar panel with the best Solar Panel. There are many other factors that can impact overall quality, including durability, cost, warranty, and power.

Efficiency is a key consideration in residential solar. Here's why.

Faster payback period

Your solar power system will produce more power and you'll be able to recoup your initial investment more quickly. Although the price of solar panels may seem daunting, efficient panels will reduce your electricity bills and accelerate your solar payback.

Another thing to remember is that the more efficient the solar panels, the fewer inverters and solar panels you will need to reach your home energy goals.

Better for Limited Space

There is limited space for solar panels in many residential solar energy projects. While some might think their roofs are large enough, zoning laws and regulations often require gaps between panels and between arrays and sides of roof. High-efficiency panels are ideal for homes with smaller roof spaces.

Efficiency won't be as important in commercial solar panels because you have more space.

Doing more with less

Not only will you have to work with limited space but also, the cost of solar panels can be lower. Trina Solar's head of efficiency research, and development, Dr. Yifeng Chen says that increasing module efficiency is a key way to help customers save money on land, labor, and cables.

High-efficiency panels are more efficient and require less materials, shipping costs, and waste. It may not seem like much to shave off one or two panels from your solar array, but seeing as the U.S. averages some solar cells that can capture infrared radiation. This would greatly increase efficiency.


Solar panels can be subject to extreme weather and high temperatures. Solar panels work better in colder temperatures if they are able to operate without overheating. Durable panels that can withstand high temperatures will provide greater efficiency and longevity.


To ensure that solar panels last for a long time, they need to have a protective coating. The problem is that the protective coating should not reflect the energy that the solar cells are trying capture. High-efficiency panels will have protective coatings of high quality that reflect as little light as possible. This will increase overall energy production.

Environmental Factors Affecting Efficiency

Solar panel efficiency is largely determined by the solar cell technology used in their construction, but there are many other factors that can affect the power generated by your system.

Climate and Latitude

Your solar energy system's efficiency will be affected by your climate and latitude. The more direct sun you receive each year, the closer you are to the equator. Climate also plays a role. Your system will not produce as much if it is often rainy or covered by clouds.

Solar Panel Orientation

Your panel orientation can also affect efficiency, just like the role of latitude. The best direction to place your solar panels is towards the south if you are in the northern hemisphere. If you're in southern hemisphere, you should face the north. Your system will not work as efficiently if your roof isn’t at the right angle for solar.

Dirt, dust or grime buildup

This is a very important factor that should not be overlooked. You might be shocked at how much production you lose if you don't clean your panels. It's easy to give your panel the regular maintenance it deserves to keep your home running on clean energy.

How to Choose the Most Economical Solar Panels

As the industry recognizes its value, solar panel manufacturers are making great strides in improving their efficiency. Monocrystalline panels, which are highly efficient, are best for residential solar systems because they have the smallest amount of space. This is why the top solar companies should have certifications to sell and install efficient solar panels.
