Sunpower P3 370

SunPower Performance 3 370 W Solar Panel

If you are in the market for a solar panel, you have probably heard of SunPower. SunPower is the leading manufacturer of high-quality solar panels, and they offer a range of products to suit every budget and need.  One of their most popular products is the P3 370 W solar panel. But how does it compare to SunPower’s Maxeon 3 solar panel? In this article, we take a close look at both panels and compare their features and benefits.

SunPower’s 30+ years of material and manufacturing expertise provide a superior understanding of how to design solar panels. This enables SunPower to offer outstanding power, dependability, value, and cost savings. The Performance 3 (P3) panel’s black frames and back sheets complement your roof nicely, without obscuring it. Their robust and flexible cell connections offer some of the best reliability possible, while their distinctive electrical bussing reduces panel temperatures, ensuring greater durability. SunPower Performance panels are the most widely used shingled solar panel in the world. Their cutting-edge cell shingling technology is designed to reduce some of the most significant causes of system failure in traditional front contact panels.

Main Features

  • The enhanced active cell area provides greater power and efficiency over preceding generation solar panels.
  • The SunPower P3 370 W solar panels generate up to 7% more energy in the same area than conventional mono PERC solar panels, over 25 years.

SunPower P3 370 W Solar Panel vs SunPower Maxeon 3

Both the P3 and Maxeon series solar panels offer great value for money – but is there a clear winner?

How Do These Two Solar Panels Compare?

There are a few key factors to consider when choosing between SunPower Performance 370 W and Maxeon 3 solar panels. 

  • The first is the efficiency of the panels. The SunPower Performance panel is less efficient, meaning it will produce less power per square metre than the Maxeon 3 panel. 
  • Another important factor to consider is the warranty on each panel. The SunPower P3 panel comes with a 25-year warranty, while the Maxeon 3 panel has an impressive 40-year warranty. The best in the industry! 
  • Finally, think about the price. The SunPower P3 panel is less expensive than the Maxeon 3, but it may be worth paying for the Maxeon 3 to get increased efficiency (= more savings over time!) and a longer warranty. 

The SunPower P3 and Maxeon 3 series of solar panels offer high performance and efficiency. The P3 series is a cost-effective solution for most domestic solar installations, while the Maxeon 3 series offers better aesthetics, efficiency, performance, and longevity – but at a price. Ultimately, it’s up to you to decide which solar panel is right for your needs!
