SunPower Corporation (NASDAQ:SPWR) announced recently that they have strengthened their industry-leading solar power warranty, which guarantees power performance and high-quality product for up to 25 years, even when exposed to unfavorable environments such as harsh weather, extreme temperatures, panel aging and much more. The latest warranty will make the company be the leading in producing the safest and long-term energy solutions for businesses, residential homes, and utilities.

Due to the Industrial low power degradation rate, the SunPower panels will effectively manage to deliver more power and thus bringing more savings to the company. The SunPower has guaranteed at most 98% electricity for the initial year which will be followed by a maximum degradation rate of about 0.25% every year for the next 24 years. As a result, the outcome would be 72% power level towards the end of 25 years in comparison to the current conventional solar panels which have a guarantee of about 80% after 25 years.

SunPower which established its first 25-year Combined Power and Product Warranty five years ago has continued to produce the high power that is not only reliable but also valuable products to its customers. According to Tom Werner, the president, and CEO at SunPower, the company produces one of the best warranty solar panels across the world and their proven performance is confirmed by the consumers’ feedback and the field testing done under a variety of real-world environmental conditions.

Furthermore, SunPower in collaboration with the National Renewable Energy Laboratory (NREL), has built a robust technique to measure the solar panel degradation at various rates over a defined time frame. The new method indicates that the SunPower solar panel usually degrades less than 0.25% which is about 50% less the annual degradation of the normal solar panels on the market.

In addition, the SunPower Complete Confidence Warranty which was effective of July this year also covers the servicing required to correct any defective parts once the client’s panels are installed by the SunPower’s authorized installers worldwide. The warranty is available to all consumers for the SunPower E- and X- Series solar panels.
