en.Wedoany.com Reported - SunPower Inc. announced the successful completion of a megawatt-scale solar system at the Millenium project, a 330-home community in Palm Desert, California. The system has a capacity of 977 kilowatts and is expected to generate over 1.6 million kilowatt-hours of clean electricity annually, with system performance guaranteed for 30 years. SunPower achieved a Net Promoter Score (NPS) of 90 for this project.

Guy Winters, President of PearlX, the owner of the Millenium project, stated that this model embodies the "Energy Estate" concept, generating tangible returns through infrastructure. SunPower's NPS of 90 validates the partner selection criteria: quality installation, disciplined execution, and zero excuses.

SunPower CEO T.J. Rodgers noted that the system uses solar panels to replace traditional roofs, providing shade for residents and vehicles. The NPS is measured using an industry-standard system ranging from -100% to +100%. According to SurveyMonkey's benchmark analysis of 150,000 companies, an NPS between -100% and 0% places a company in the lowest quartile, while scores from 0% to 70% correspond to ratings from "good" to "excellent." Reports indicate that Apple leads with an NPS of 70%. Rodgers stated that although large, complex projects can achieve high NPS scores, SunPower's overall NPS following its acquisition of the old SunPower in the second quarter of 2025 is -25%, due to the old SunPower's bankruptcy causing hundreds of projects to halt, including Millenium. Issues at the Millenium project were actively resolved by a quality team led by Surinder S. Bedi. SunPower has improved each quarter since Q2 2025, with a target of achieving an NPS above 70% by Q2 2027.

Rodgers also mentioned that the installation cost of solar systems is declining year over year, while utility electricity costs are expected to rise annually, creating growth momentum for the residential solar market. According to EnergySage, the cost of a home solar system in California is approximately $2.47 per watt, with a payback period of 7.3 years. Data from the U.S. Energy Information Administration shows that only 15% of California households where solar is economically viable have installed it, with a national installation rate of 7%. This means 85% of California households and 93% of homeowners nationwide are potential future customers.
