High Efficiency Solar Panels: The 5 Most Efficient Solar Panels on the Market in 2018

Rate this post

When looking for the most efficient solar panels on the market, the first thing you need to be aware of is that just because a solar panel boasts that its main feature is efficiency, that doesn’t always mean that you are going to be provided with the best return on your investment.

There are several factors to take into account when it comes to solar efficiency and when the time comes to make a decision about which ones you are going to buy, you might find that cheaper panels that offer a lower efficiency are going to be a better solution for you if you have a lot of space, as you can just install more of them and they will still produce the same amount of energy as the more efficient (and often more expensive) premium models.

If you are amongst the thousands of people on the quest to find the most efficient solar panels on the market to complete your PV rooftop system, then you don’t need to spend any more time researching. In this article, we will be reviewing the 5 most efficient solar panels on the market this year, so you can make an informed decision about which panel is going to be right for you.

Which Type of Solar Panel is Most Efficient?

Monocrystalline solar panels have been proven to be the most efficient by a long shot, with an efficiency rating of between 15-22%. While this might sound like a low figure, it is actually more than sufficient to power an entire household.

The reason these panels are so efficient is that theyare made out of high purity rating silicon that is designed to withstand high temperatures and extreme weather conditions. These types of panels also have the added benefit of requiring less space, making them a perfect choice if you live in the city or completely off-grid.

SunPower X-Series Solar Panels

SunPower X-Series Solar Panels

SunPower is the largest manufacturer of crystalline solar panels in the world. They introduced the SunPower X22 360W Premium Plus solar panel to the consumer market last year,and it remains the most efficient solar panel available worldwide.

These panels boast a remarkable 22.2 percent efficiency rating, featuring the latest technology in solar PV panels. They are incredibly durable- built to withstand extreme climates, making them an attractive option for customers worldwide.

Key Benefits

  • High Efficiency: the X-series solar panels generate more energy per square foot and produce 38% more power per panel than competitor brands
  • Maximum Performance: the panels have been cleverly designed to deliver optimal energy in realistic conditions like partial shade and hot temperatures
  • Advanced Technology: X-series panels will deliver unmatched power and performance thanks to innovative Maxeon technology
  • checkExtremely Durable: the only cell in the world that is built on a solid copper foundation, making it resilient to corrosion and cracking with age

Drawbacks

  • Price: they are more expensive than other solar panels, but it’s not surprising given the premium features and quality they promote

LG NeOn R Solar Panels

Panasonic N 330W

The all-time favorite solar panel providers have outdone themselves with their new and improved approach to the manufacturing process of their solar panels. Their new hetero junction cell technology features two separate layers of high-quality material to create each cell. This means that the failure rates of these solar panels are incredibly low, and they also provide an efficiency of 19.7%.

Key Benefits

  • Higher energy outputs: thanks to new and improved heterojunction technology
  • High efficiency:an industry-leading temperature coefficient guarantees efficiency even at high temperatures
  • Unique water drainage system: meaning your panels won’t get dirty as quickly. More sunlight results in more power
  • check 25-year product and performance warranty: the power output after 25 years is superior to that of its competitors
  • checkWell priced: these panels fall in the mid-range price bracket

Drawbacks

  • Space: similar to the LG solar panels, if your roof space is limited, you might not have enough space to install enough panels for your energy consumption needs.

TrinaSolar Allmax

TrinaSolar Allmax

TrinaSolar is one of the largest solar panel manufacturers in the world. Their Allmax solar panels provide versatility, as well as efficiency.

Key Benefits

  • Excellent Price: while they are not as efficient as the product above, they are significantly more affordable
  • Generate high amounts of energy: even when space is limited, the Allmax solar modules still perform very well
  • Good Quality: these versatile solar panels are built to last

Drawbacks

  • Not as efficient as other panels available on the market, but this is compensated by the price.

Solaria Power XT
