Renova Energy or SunPower Out of Business? Local Repair, Rescue & Battery Retrofits
The closure of SunPower and Coachella Valley installer Renova Energy left thousands of desert homeowners with unmonitored arrays, failed microinverters, and stalled permits. OC Solar (CSLB #1023627) steps in with licensed, in-house technicians for SunPower repair in Palm Springs and the Coachella Valley, Renova Energy system diagnostics, and Tesla Powerwall 3 or Enphase battery additions.

How OC Solar supports orphaned Renova Energy & SunPower homeowners
Whether your Coachella Valley array stopped producing, needs a battery for 4–9 PM peak cooling loads, or was left incomplete before Permission to Operate, start with the path built for your situation.
SunPower & Renova Repair in Palm Springs & Coachella Valley
Tripped breakers, failed SunPower/Enphase microinverters, dark PVS6 monitoring, or desert-heat inverter faults. Our in-house C-10 electrical technicians test your array on-site and provide an itemized repair scope.
Add Tesla Powerwall 3 or Enphase Battery to Existing SunPower System
Coachella Valley summer AC loads run hard into the evening peak. We AC-couple Tesla Powerwall 3, Enphase IQ Battery 5P, or FranklinWH storage onto existing SunPower and Renova arrays on both SCE and IID.
Unfinished Project & PTO Rescue
Equipment on the roof but city inspection failed, or inspection passed with no SCE or IID Permission to Operate? We audit your permit packet, financing status, and interconnection file to map a clean completion path.
Existing SunPower & Renova Upgrades
Add a Tesla Powerwall 3 or Enphase battery to your existing SunPower system
You don't need to replace working SunPower or Renova panels to get modern outage backup and evening peak shaving. Our engineers design AC-coupled battery additions tailored to your existing array and desert utility tariff.
- Tesla Powerwall 3 (13.5 kWh usable, 11.5 kW continuous output, 185 A LRA motor-start capability) starts heavy desert AC compressors and integrates via AC coupling with existing SunPower or Enphase arrays.
- Enphase IQ Battery 5P & 10C modular LFP storage pairs natively with eligible Enphase IQ microinverter systems and replaces dark monitoring with live Enphase App visibility.
- FranklinWH aPower 2 (15 kWh LFP, 10 kW continuous output) with the aGate smart controller manages high-draw pool pumps, EV chargers, and dual AC units automatically during grid outages.
- Under third-party Prepaid Solar & Battery Lease/PPA options, the commercial financier claims the federal §48E credit and passes roughly 30% of the value through in upfront pricing (the homeowner §25D credit expired December 31, 2025).

Coachella Valley & Inland Empire Field Coverage
Engineered for 115°F desert roofs, SCE NEM 3.0, and IID Net Billing
Servicing an orphaned solar system in Palm Springs or Indio takes more than a generic service van — it requires hardware rated for extreme desert heat and an interconnection team that knows both SCE and IID.
Microinverter & String Diagnostics
We service Enphase IQ/M-series microinverters, SunPower-branded AC modules, SolarEdge optimizers, and string inverters exposed to 115°F+ Coachella Valley roof temperatures.
AC-Coupled Battery Retrofits
Pair your existing SunPower or Renova solar array with Tesla Powerwall 3 (13.5 kWh / 11.5 kW continuous) or Enphase IQ Battery 5P without ripping out working rooftop panels.
Manufacturer RMA & Warranty Help
We check serial numbers against active OEM warranty programs (Enphase, REC, Qcells, SolarEdge, Tesla) so eligible replacement hardware isn't paid for twice.
SCE & IID Interconnection Fluency
From SCE territory in Palm Springs, Cathedral City, and Rancho Mirage to IID Net Billing territory in Indio, La Quinta, and eastern Palm Desert, we file the right utility paperwork.

Renova Energy & SunPower Rescue FAQ
Common questions from Coachella Valley & Riverside County owners
Straight answers on SunPower microinverters, Renova Energy systems, warranty claims, and battery additions.
OC Solar (CSLB #1023627) dispatches licensed in-house technicians across Palm Springs, Palm Desert, Rancho Mirage, Cathedral City, Indio, La Quinta, and all of Riverside County to diagnose and repair orphaned Renova Energy and SunPower solar systems. Whether you have an offline inverter, failed Enphase or SunPower microinverters, a monitoring gateway fault, or an unfinished installation, you can submit your system details at /service-request for a clear written assessment before any paid work begins.
Yes. Many Coachella Valley homes installed through SunPower or its regional dealers use SunPower-branded modules paired with Enphase-manufactured microinverters, SolarBridge microinverters, or string inverters, along with PVS5/PVS6 monitoring gateways or SunVault storage. Our technicians test production string by string, identify whether a fault is in the microinverter, combiner, monitoring gateway, or breaker, and explain which components can be repaired, replaced, or claimed under surviving OEM equipment warranties.
In most cases, yes. Adding a Tesla Powerwall 3 (13.5 kWh usable capacity, 11.5 kW continuous output), an Enphase IQ Battery 5P, or a FranklinWH aPower 2 to an existing SunPower or Renova solar array is one of the highest-impact upgrades in the Coachella Valley. We inspect your existing inverter architecture, main electrical panel, and utility tariff — whether Southern California Edison (NEM 1.0, NEM 2.0, or NEM 3.0) or Imperial Irrigation District (IID Net Billing) — so the battery retrofit is engineered to protect your afternoon and evening AC loads without surprises.
Installer workmanship warranties from a closed contractor are separate from equipment manufacturer warranties. While a bankrupt installer's labor warranty or service contract may no longer be honored by that installer, underlying OEM hardware warranties (such as Enphase microinverters, REC or Qcells modules, or SolarEdge inverters installed by Renova) may remain active under the manufacturer's own terms, registration, and RMA rules. We verify your exact hardware serial numbers and tell you honestly which parts qualify for manufacturer replacement versus independent repair.
Coachella Valley utilities split along geographic lines: Palm Springs, Cathedral City, most of Rancho Mirage, and western Palm Desert are served by Southern California Edison (SCE), while Indio, La Quinta, and eastern Palm Desert (east of Washington Street) are served by the Imperial Irrigation District (IID). Repairing like-for-like failed components generally keeps your existing interconnection intact, whereas adding panel capacity or battery storage must follow SCE's or IID's specific modification rules. We verify your utility bill and interconnection agreement before recommending an expansion.
Yes — we assess unfinished projects across Riverside County where permitting, installation, city inspection, or SCE/IID interconnection stalled before PTO. Because feasibility depends on equipment ownership, any active loan/lease/PPA contract, city permit status, and installed workmanship, start with our unfinished-project intake so our team can review your records and confirm what can responsibly be completed.
