What are the most efficient solar panels?
Today, monocrystalline PERC and N-type IBC solar cells have efficiencies of 18% to 20% and above. This sets a new standard for high-efficiency residential solar panels in the future, as commercial solar panels begin to operate at peak operating efficiencies in excess of 20 to 22 percent. What’s more, extensive research into photovoltaic (PV) solar energy is ongoing, with new technologies continuing to debut at high efficiency levels.Solar panels work by converting sunlight into energy to power our homes. Solar panel efficiency refers to how much sunlight reaches the panel and is converted into electricity, and the efficiency rating measures how well the panel completes this process. The higher the percentage, the more efficient the panel is. Not all sunlight is absorbed – most solar panels today operate at around 19-21% efficiency. Generally speaking, the higher the cost-efficiency rating of a solar panel, the more expensive it will be.
In this article, we will talk about which is, the importance, and the cost of the most efficient solar panel.

Why is solar panel efficiency important?
High efficiency solar panels have several benefits.
Cost: High efficiency panels may cost more, but they can also help you save money because you can install fewer panels to meet your energy needs.
Energy production: Efficient solar panels are a better value because they produce more electricity than less efficient panels. Higher solar panel efficiency increases the amount of energy produced by the panels.
Net metering: Generating more electricity can increase your net metering returns. Net metering allows you to exchange excess energy from your solar panels for a credit on your electricity bill.
Battery Storage: The best solar cells can serve as temporary power sources during power outages. Having most efficient solar panels can help you replenish your battery quickly after use.
To help you sort through the vast amount of data, we’ve narrowed down the top five most efficient solar panels. To determine the most efficient solar panels, we looked at each top manufacturer’s performance in the following categories and compiled the information:
Most Efficient Solar Cells
The most efficient solar panels on the market generally use either N-type (IBC) monocrystalline silicon cells or other highly efficient N-type variations, including heterojunction (HJT) and TOPcon cells. Most manufacturers traditionally used the standard and lower-cost P-type mono-PERC cells; however, many large-volume manufacturers, are now rapidly shifting to more efficient N-type cells using HJT or TOPcon cell designs.
Efficiency of panels using different cell types
- Polycrystalline – 15 to 18%
- Monocrystalline – 16.5 to 19%
- Polycrystalline PERC – 17 to 19.5%
- Monocrystalline PERC – 17.5 to 20%
- Monocrystalline N-type – 19 to 20.5%
- Monocrystalline N-type TOPcon – 21 to 22.6%
- Monocrystalline N-type HJT – 21.2 to 22.8%
- Monocrystalline N-type IBC – 21.5 to 23.6%
Cost of the most efficient solar panels
The price of high efficiency solar panels will vary depending on the brand you purchase, where you live, who installs the solar panels, and other factors. However, there are several ways to reduce costs through solar panel incentives and rebates, such as:
Residential Clean Energy Credit: The Residential Clean Energy Credit is a federal tax credit that allows you to recoup 30% of the cost of solar installation through 2032. The credit will decrease to 26% in 2033 and then to 22% in the final year of 2034.
State Incentives: Our resources can help you discover state solar incentives and rebates to lower the overall cost of installing a solar panel system.
Learn more about return on investment: Calculating the return on investment of solar panels can help you choose high-efficiency solar panels that fit your budget.
What makes solar panels efficient?
There are other factors to consider when evaluating the efficiency of solar control panels. For example, wattage, panel size, construction, and materials also affect the total solar output of a panel. These factors affect the amount of solar energy created by the panels. However, they don’t always correlate in the way you expect. For example, simply having a high wattage doesn’t necessarily mean a panel is more efficient. Therefore, it is better to check all the specifications of the solar panels rather than focusing on just one aspect. Here are other features that help improve solar panel efficiency:
Wattage: The power of high efficiency solar panels is measured in watts. Watts are voltage multiplied by current.
Panel size: Larger panels generally produce more wattage, which increases efficiency.
Structure: The composition of a solar panel includes busbars that conduct electricity within the panel. The location and number of busbars affect efficiency.
Materials: Solar panels are made from various forms of silicon. They can be single-crystal, polycrystalline, or amorphous, with single-crystal being the most efficient.
Reflection: You want your solar panels to absorb sunlight, not reflect it. All solar panel brands have low reflectivity due to anti-reflective coatings.
How to improve the efficiency of solar panels?
Adding a quality solar cell to your home solar system is the easiest way to increase the efficiency of your solar panels. A solar cell conserves the energy produced by solar panels during peak hours of the day so that you can use it during off-peak hours. Here are some other ideas for improving solar panel efficiency in various weather conditions:
Make solar panels more efficient in cold weather
Cold weather does not necessarily harm solar panel efficiency if there is still sunlight. However, if your panels are covered in snow for multiple days in a row, it may cause a temporary decrease in efficiency. Mounting solar panels at a slightly steeper angle can help melt snowfall off faster.
Improve solar panel efficiency in hot weather
Contrary to what you might expect, extreme heat can reduce the efficiency of solar panels. While you can’t make a hot day cooler, you can choose panels with a lower temperature coefficient or the best solar panels for hot climates The temperature coefficient measures resistance as a function of temperature. You can find the panel’s temperature coefficient in the product specifications. That said, panels with a low-temperature coefficient also tend to have a reduced overall efficiency rating, so there’s a trade-off. If you live in an area with an unusually hot climate, talk to your solar installer about whether low-temperature coefficient panels are a good option for you.
Improves solar panel efficiency when it rains
The good news is that rain helps make solar panels more efficient in the long run because it washes away dirt and debris that prevents the panels from absorbing sunlight.
Maintain your high efficiency solar panels when it snows
When you install them on your rooftop, it’s essential to have some solar panel maintenance steps in the winter. Adjusting the angle of your solar panel mounting is beneficial in increasing the efficiency of your solar panels during the winter months as well as the amount of power they generate.
How is solar panel efficiency calculated?
Cell efficiency is determined by the cell structure and the type of substrate used, which is usually P-type or N-type silicon. Cell efficiency is calculated by fill factor (FF), which is the maximum conversion efficiency of a photovoltaic cell at optimal operating voltage and current.When you’re shopping for high-efficiency solar panels, the efficiency rating will be listed on the panel’s datasheet. But how exactly is it calculated? There’s actually a pretty easy formula for calculating solar panel efficiency:
Efficiency = [Power output of panel / (Area of panel x solar irradiance)] x 100
When solar panels are tested in the lab under Standard Test Conditions (STC), it’s assumed they will receive irradiance levels of 1,000 watts of sunlight per square meter. Knowing this, let’s calculate the efficiency rating for a:
350-watt panel with an area of 1.8 square meters:
Efficiency rating = [350 watts / (1.8 m2 x 1,000 watts per m2)] x 100
Efficiency rating = 19.4%
So, this 350-watt panel has an efficiency rating of 19.4%. Not bad!
The bottom line on home the most efficient solar panels
Whether you finance, lease your solar panels, or use a solar power purchase agreement (PPA), the efficiency of the panels is a key factor in how much electricity your home solar system produces. Keep in mind that if you are looking to install solar panels for your RV, the specifications will be significantly different than residential solar panels.
