Key Terms

net promoter score, nps, first-pass yield, kilowatt hour (kwh)

4 terms

net promoter score technical

"awarded the company a 90% Net Promoter Score (NPS)"

Net Promoter Score (NPS) is a single-number measure of customer loyalty based on asking customers how likely they are to recommend a company’s product or service to others; responses are grouped and converted to a score from -100 to +100. It matters to investors because a high NPS suggests strong customer satisfaction, lower churn and more organic growth through word-of-mouth—like a reputation score that can predict future sales and brand resilience.

nps technical

"NPS scores run from -100% to 100%, with scores above 70% considered"

Net Promoter Score (NPS) is a single-number measure of how likely customers are to recommend a company’s product or service to others, usually gathered by asking one simple question and scoring responses on a scale. It matters to investors because it acts like a quick pulse on customer satisfaction and loyalty — higher scores often mean steadier sales, easier growth, and lower customer churn, much like word-of-mouth fuel for future revenue.

first-pass yield technical

"Quality Standard is to achieve a first-pass yield of 100% on every step"

First-pass yield is the percentage of units or outputs that meet quality standards on the first attempt without needing rework, repair, or additional inspection. For investors, it signals how efficiently a company produces goods or delivers services—higher first-pass yield usually means lower costs, fewer delays, and more reliable supply, which can support steadier margins and better operational predictability. Think of it as the share of cookies that come out of the oven perfect the first time.

kilowatt hour (kwh) technical

"drives the lowest cost per kilowatt hour (kWh), but also the exceptional"

A kilowatt hour (kWh) is a measure of energy equal to one thousand watts of power used for one hour — like running a 1,000-watt hairdryer for one hour or ten 100-watt bulbs for an hour. Investors care because it’s the common unit for electricity production, consumption and billing, so it directly affects revenue, operating costs and the economics of power plants, renewable projects, batteries and utility bills.

High NPS Milestone Reinforces Superior Product, Quality and Customer Success

OREM, Utah, May 29, 2026 (GLOBE NEWSWIRE) -- SunPower Inc. (“SunPower,” the “Company,” or Nasdaq: “SPWR”), a solar technology, services, and installation company, today announced the successful completion of 26 Commercial Solar Projects for Starbuck’s, which awarded the company a 90% Net Promoter Score (NPS), marking a significant milestone in SunPower’s execution, quality and customer success strategy. NPS scores run from -100% to 100%, with scores above 70% considered world-class.

SunPower uses the NPS a quality method to measure the full customer experience. NPS is based on a standardized customer survey question: On a scale of 0 to 10, how likely are you to recommend this company to a friend or colleague? SunPower’s NPS results thus reward a composite of customer experience, advanced product technology, installation quality, system activation performance, and ongoing customer support.

SunPower CEO, T.J. Rodgers said, “NPS performance rarely makes headlines, yet across our industry, the most common failure mode is inconsistent execution – leading to delays, customer dissatisfaction, and value erosion. After a year of focused effort, we were highly honored to receive an NPS score of 90% from Starbucks, a reflection of their view of SunPower’s commitment to quality.”

Surinder S. Bedi, Executive Vice President, Quality, Engineering and Customer Success at SunPower, added: “We worked diligently to achieve high NPS from Starbucks. SunPower’s Quality Standard is to achieve a first-pass yield of 100% on every step – a true commitment to zero-defect quality, which, in turn, not only drives the lowest cost per kilowatt hour (kWh), but also the exceptional reliability and aesthetics that will serve Starbucks customers for decades.”
