Is $4,850 to fix a 10-year-old solar system by replacing all microinverters and the monitoring system a fair price?
Project Details
My solar system is 10 years old, with 16 250W SPR-X20-250-BLK-B-AC panels. Currently, only 2 of 16 panels are producing power, as 14 microinverters are broken. The original microinverter manufacturer, SolarBridge, is defunct, and there are no compatible parts, even though Enphase now owns them. My current power bill is about $3300 a year, and I'm on NEM 1.0 with SoCal Edison. I'm questioning if fixing the system is worth the cost, or if I should abandon it, especially given my lack of faith in SolarBridge's reliability. I regret installing solar, as the original $19,000 system (4kW in 2016) hasn't paid itself off, and I've had issues like this. I'm also concerned about potential roof issues (leaks, broken tiles, reroofing) and the fact that my asphalt shingles are 10 years old. I'm exploring if this fix or a full replacement would qualify for a solar tax credit. I'm also considering upgrading the panels too, but I'm unsure if that would require new permits or cause me to lose my NEM 1.0 status, especially with California potentially forcing NEM 1.0 into 3.0 or 4.0.
Quote Details
The quote is for a whole system retrofit to fix a 10-year-old solar system where 14 out of 16 microinverters are broken. The original microinverter manufacturer is defunct, requiring a full replacement of components. This quote is discounted through the Enphase retrofit program. - Replace all microinverters with Enphase IQ7+ - Replace monitoring system with Enphase Envoy - Parts cost (estimated with tax and shipping): $2350 - Labor cost: $2500 - Individual part pricing: $95 per microinverter, $510 for combiner

Add an Enphase 5P battery and upgrade solar inverters
This quote is for adding an Enphase 5P battery to my existing 11-panel (4.785 kW) Enphase solar solution, which currently uses IQ7 inverters and an IQ Combiner 4. The primary purpose of the battery is for time of use shifting in my grid-tied NEM 2 system. The quote includes several components: - Enphase 5P battery installation - Planning and design services - Replacement of my existing 11 IQ7A inverters with IQ8A inverters. This upgrade is stated as necessary because PG&E is reportedly requiring Power Control System (PCS) limitations to prevent overloading and meet the 120% rule for grid-tied setups, which the IQ7 micros are not capable of handling.
