Expert Statements
Paul Zimmer, Founder and owner of Detail Solar
“This project showed us how impactful repowering strategies can be when original legacy string inverter architecture is underperforming.”
Paul Zimmer, Founder and owner of Detail Solar
“With Enphase IQ9 Commercial Microinverters supporting 480 V infrastructure, we modernized the system, minimized future downtime, and restored energy production with confidence.”
Jim Laskowski, Director of operations at Endless Energy
“The inverters at Peirce had reached the end of their life, but most of the panels still had plenty to give”
Jim Laskowski, Director of operations at Endless Energy
“Putting two modules on each Enphase microinverter kept the cost down. Once the system is back online, module-level data will show us exactly which panels need replacing and which ones we can leave alone.”
Ken Fong, Senior vice president of sales at Enphase Energy
“A lot of commercial solar is producing less than it should because the inverters gave out, not the panels”
Ken Fong, Senior vice president of sales at Enphase Energy
“Repowering with Enphase keeps those modules and racking working, makes the site safer, and puts a 25-year warranty on the new electronics.”
Ken Fong, Senior vice president of sales at Enphase Energy
“When other inverters are not getting the job done, Enphase is the partner installers and asset owners can trust to get those systems producing again, and keep them producing for decades.”
FREMONT, Calif., Oct. 14, 2026 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company, today highlighted commercial and industrial (C&I) repowering projects across the United States that use Enphase(®) IQ9™ Commercial Microinverters. Installers are replacing aging and failed string and central inverters with Enphase microinverters to restore energy production on existing commercial arrays, without the need for new modules or racking. Repowering builds on Enphase's long-standing focus on quality and reliability.
Many commercial solar systems installed over the past decade are underperforming because their inverters have aged out or failed. Repowering with Enphase microinverters lets asset owners keep the hardware they already own and gain module-level monitoring. Enphase's distributed architecture keeps a single module fault from taking the whole system down: issues stay isolated to individual modules while the rest of the array keeps producing. This distributed architecture also improves installation safety and provides inverter-level monitoring, all backed by an industry-leading 25-year warranty.
