SunPower Performance solar panels provide long-term cost savings for organisations due to several key factors. Firstly, their low annual degradation rate ensures consistently high energy production throughout their lifespan. Secondly, they utilise cell technology with a low-temperature coefficient which enables optimal energy production even in extreme weather conditions, leading to consistent savings year-round. Additionally, strong shade management minimises energy loss in a variety of shaded scenarios, maximising energy harvest in varying environments. Lastly, SunPower Performance solar panels robust durability and longevity eliminates the need for frequent replacements and lowers maintenance costs. These combined features make SunPower Performance solar panels a reliable and cost-effective solution for reducing energy expenses and achieving long-term financial benefits.

A better product, should have a better warranty, and that is why SunPower Performance panels have a comprehensive 30-year warranty that covers Power, Product and Service (subject to terms and conditions that can be found in our warranty documentation). 

Our latest generation, SunPower Performance 7 solar panels are manufactured for long-term durability—covering defects related to workmanship and materials for a full 30 years. The 30-year warranty for SunPower Performance 7 solar panels requires registration, otherwise our 25-year warranty applies, and this warranty is not available for earlier generation SunPower Performance solar panels, where a 25-year warranty applies. 

Some manufacturers of standard panels go as low as 12 years on their product defect warranty, which could leave your organisation open to risk if anything should go wrong with the panel. It is best to carefully review warranty documentation before investing in solar panels for your organisation.

SunPower Performance solar panels offer a compelling advantage for cost-conscious organisations. Their high power and efficiency specifications result in fewer panels being required to meet energy targets. This not only reduces upfront costs for the panels themselves, but also for balance of system costs including installation labour, racking and supporting hardware.

We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 8% more energy yield in a fixed space over the first 30 years of operation when compared to Conventional mono PERC Panels1.
