Sunpower vs REC Solar Panel Comparison | All You Need To Know

This solar comparison guide will compare two of the top solar panel manufacturers in the market: REC and Sunpower.

Both companies have been at the forefront of developing cutting-edge technology to help homeowners maximise their energy savings with solar panels.

This guide will explore the strengths and weaknesses of each company and its solar panels, helping you decide which is best suited for your needs.

Quick Guide

Overview: Both brands offer high-quality solar panels. But Sunpower outperforms REC Solar in terms of performance, efficiency and warranties.

Efficiency: Sunpower has the highest efficiency rating at 20.4%, although REC offers a decent maximum efficiency of 19.2% for its solar panels.

Power: Sunpower’s Maxeon Gen II has a maximum power output of up to 327 watts, while REC Solar offers up to 320 watts.

Warranty: Sunpower offers a 25-year product and linear power output warranty. REC provides a slightly shorter 20-year product warranty but a similar 25-year linear power output warranty.

Cost: Sunpower solar panels are on-average cheaper ($1.27/watt) than REC Solar ($1.32) for 6, 8 and 10KW solar systems, and they have a slightly longer product warranty. However, there is little to choose between them, as prices vary from one installer to another.

Choosing Sunpower Vs REC – Which Is Best?

Sunpower and REC offer a range of photovoltaic (PV) panels suitable for residential, commercial and industrial applications.

Both companies have achieved excellent ratings for product quality, performance and reliability.

However, Sunpower has a competitive edge in its efficiency and power output. The Maxeon Gen II series offers up to 327 watts of power and 20.4% efficiency, significantly higher than REC’s peak output of 320 watts and 19.2% efficiency, making Sunpower the clear winner for those looking for a high-end PV solution.

Of course, there are other factors to consider when choosing a PV panel, such as weight, ease of installation, durability, maintenance, and overall system price.

The choice between the two largely comes down to your budget and how you plan on using the solar system.
