There’s more to finding the most efficient solar panels than knowing you’re getting your money’s worth from the best product on the market. Solar panel efficiency refers to how well a solar panel system can convert sunlight into usable energy—the higher the efficiency rate percentage is, the more energy the panels can convert into electricity.
For example, solar panels that have 20% efficiency can easily convert 20% of sunlight into electric energy. Anything that produces more than 20% efficiency can be considered high efficiency solar panels—and these often come from top solar panel brands, such as LG and Silfab. That being said, it’s still essential to research on your own and understand the factors contributing to a solar panel’s quality before you switch to solar.

Investing in solar panels is the right step towards more sustainable energy usage. Top solar panels available in the market will also give you a greater return on investment. Here’s why you should consider investing high efficiency solar cells:
Monocrystalline panels—sometimes called mono panels—offer one of the highest solar efficiency rates on the market. They often have the heftiest price tag, but their long-term benefits definitely outweigh the initial investment.
Mono panels are generally compact—making them the top choice for residential properties and commercial properties with limited roof space. They feature a sleek design that blends seamlessly with rooftops. And they typically have the longest life span among solar panels. In fact, they can last up to 40 years with proper maintenance.
The efficiency rate of mono panels ranges from 15% to 20% on average. However, keep in mind that colder climates might affect their performance.
Polycrystalline panels—or poly panels—are one of the most affordable yet efficient types of solar panels. That being said, they don’t provide as much efficiency and power output as mono panels. So, compared to a scenario wherein you use mono panels, you would need more poly panels to support your daily energy needs.
Poly panels can last from 25 to 35 years with proper maintenance. They cost less than mono panels and can easily perform well in cooler climates.
Before scheduling residential or commercial solar panel installation of poly panels, however, consider the fact that they are larger than mono panels and therefore require more roof space. These panels are blue, making them more noticeable on the rooftop, and might clash with the building facade’s aesthetics.
Thin-film panels are rated the least efficient among solar panel ratings for residential solar panel systems. They also rate low on power production. As such, they aren’t the best option for homes with high energy needs. Instead, they are most suitable for sheds, stand-alone garages, and other small-scale installations.
In terms of benefits, however, thin-film panels can perform well regardless of shading or temperature levels. These panels are black so that they can blend seamlessly into the roof. They’re also the most cost-effective option. Their only drawback is that they last only about 20 years on average.
In addition to asking what are different types of solar panels and how efficient they are, it’s also important to know the structural and environmental factors that could affect solar panel efficiency. This way, you know exactly how to get the most out of your solar panel system. Here’s everything you need to know.
The overall efficiency of solar panels could be affected by solar cell efficiency. The solar cells in monocrystalline panels come from a singular silicon crystal—it’s more expensive but has greater efficiency. Meanwhile, polycrystalline panels are more cost-effective yet slightly less efficient because they use multiple silicon crystallines.
Solar panel construction also affects efficiency. For example, faulty wiring could result in lower energy conversion and power production. So, choosing a trusted installation and maintenance service provider is essential.
Various environmental factors can affect solar panel performance. One example is the accumulation of dirt, dust, debris, pollen, and other minuscule substances that seem harmless but could disrupt the panels’ absorption of solar heat.
Other factors include solar panel orientation and shading—the panels have to be at the right angle to absorb maximum sunlight — existing weather conditions, and the current temperature. Some solar panels, like monocrystalline panels, work best in warmer climates. Meanwhile, others, like polycrystalline panels, are designed to withstand cooler weather.
