Solar Repair in San Jose, CA
Licensed Solar Diagnostics & Repair by Dollens Electric
When a solar system stops producing power, the problem is rarely the panels alone. Inverters, wiring, grounding, monitoring, and service connections all work together — and when one part fails, production drops fast.
Dollens Electric provides professional solar repair and diagnostics for homeowners throughout San Jose and Santa Clara County. As a family-owned contractor holding C-46 Solar, C-10 Electrical, and B-General Building licenses, we are qualified to diagnose and repair the entire system, not just swap parts.
We don’t guess. We test, identify the root cause, and fix the issue correctly the first time.
Solar Repair for Systems That Aren’t Performing
Many homeowners first notice a problem when their utility bill spikes or their monitoring app shows a drop in production. Others discover issues after storms, roof work, or when their original installer is no longer in business.
We regularly service solar systems in San Jose, Santa Clara, Cupertino, Sunnyvale, Campbell, Los Gatos, Saratoga, and across the South Bay, including systems we did not originally install.
Whether your system is partially producing, completely offline, or reporting errors, we provide clear diagnostics and straightforward repair options.

Common Solar Problems We Diagnose and Repair
Inverter failures or fault codes
Sudden or gradual drops in energy production
Monitoring systems not reporting or updating
Loose, damaged, or corroded wiring and connections
Grounding and bonding deficiencies
Panel damage, shading issues, or failed optimizers
Systems affected by roof work or electrical upgrades
Solar problems often look simple on the surface. In reality, many failures trace back to electrical or code issues that solar-only companies are not licensed to correct.



Licensed Solar Repair Contractor in San Jose (C-46, C-10, B)
Dollens Electric holds three California contractor licenses, allowing us to repair solar systems comprehensively and legally:
C-46 Solar Contractor License — Required to service and modify photovoltaic systems
C-10 Electrical Contractor License — Required for inverter work, wiring, grounding, and service connections
B – General Building Contractor License — Required when repairs involve roof penetrations, mounting systems, or structural components
Many solar repair companies are limited to panel or inverter replacement. As a fully licensed electrical and solar contractor, we can correct underlying electrical faults, code violations, and installation defects that cause repeat failures.
This is why homeowners call us when other companies can’t resolve the issue.

Repair Work
Many common repairs are completed during the same visit. If parts or coordination are required, we explain the timeline clearly.
Warranty
We stand behind our work with a lifetime workmanship warranty and manufacturer warranties on materials we supply.
Projects Completed:
-Electric water heater installation
-Circuit breaker panel upgrade
-Electric dryer wiring and connection
From the initial consultation, it was clear I was working with a true professional. They took the time to explain each project in detail, answered all my questions patiently, and provided transparent pricing with no hidden fees.
What stood out most:
The water heater installation was flawless. They ensured everything was up to code, properly grounded, and functioning perfectly. The attention to safety details gave me complete peace of mind.
The circuit breaker upgrade was handled expertly. They assessed my home's electrical needs, recommended the right capacity, and completed the work efficiently while keeping the disruption to my daily routine minimal.
For the dryer connection, they ran wiring cleanly and professionally, ensuring proper voltage and a safe, reliable connection. Everything was tested thoroughly before they considered the job complete.
Throughout all three projects, they maintained a clean work area, showed up on time, and demonstrated exceptional craftsmanship. I'll definitely be using them for all future electrical needs!

Came back from out of town on a Friday evening to find the garage without power.
Jason from Dollens walked me step by step through all the trouble shooting over the phone to spot the issue and resolve it within minutes.
I am going back to them for all my Electrical nees!
Still my go to electrical contractor. On time, plenty of communication, professional.
Converting from propane to an electric BBQ (firewise change).
Needed a new outlet on a 20 amp circuit that had an old 15 amp style socket. These are the guys I trust to keep us safe.
Update 9/2020 - Upgraded some thermostat wiring for me with a difficult routing. Professional and quick.
Update - Jason and Josh again came through for me. In the midst of a heat wave, they were able to come to the other end of the county and fix an electrical problem at my mother's house. Got the outlets for the portable AC and lift chair back working and made the wiring safer to boot.
Original - Could not ask for better. Jason installed a new 40 amp circuit and an EVo charger for our car. (No more slow 110 charging. Yeah!) While working in our breaker panel he noted a dangerous situation left by a previous contractor who upgraded our air conditioning.
(Side note kind of disappointing the inspector didn't notice that the other contractor put in a bigger breaker on a wire that was too small. Luckily the wire insulation had just started to bubble and it didn't catch fire.)
Within a week they were able to fit us in to replace the faulty circuit as well as rewire our garage lighting to eliminate some creative but scary runs of extension cords and re-purposed outlets. Now I have bright lights and when I look up, I don't see wires draped everywhere.
We connected with Jason of Dollens Electric through our equally excellent general contractor Dan Mackey. (Who by the way had nothing to do with the faulty circuit or the creative garage lighting.)
Lastly a thank you to Jason's son Josh who got to do the crawling under the house.
Thanks Maggie and Jim!!!
I had a hard time finding a contractor who wanted to install a power meter for dynamic energy monitoring over an expensive DCC. On my first call with them they recommended an Emporia Pro which is the cheapest option for dynamic load management, so I knew that they had the best for the customer in mind. I decided to go with Wallbox's offering instead; although I picked a less common method for dynamic load management Joshua had no issues wiring everything and it was great to see that he took in my input instead of just telling me I had to install a costly DCC. I also liked that he already had a lot of prior experience installing Wallbox's car charger.
Thank you for an amazing install. Support Local!
I was pleased when they briefly reviewed an installation manual to make sure they remembered exactly how the brand worked. It was obvious Joshua already knew how to make the installation but he doubled checked anyway. (I'm glad I'm not the only person who still refers to a manual.)
Call/use them; you won't be sorry.

Thank you for your kind words! We're glad to hear that you had a great experience with us. Our team at Dollens Electric is always ready to help with any electrical problems. If you ever need assistance in the future, don't hesitate to give us a call. Thanks again!
Excellent communication and professional!
Highly recommend!
Jason seemed to know the possible cause for the problem when I told him that the parts of the house were losing power gradually, and he was right!! He came out on the same day and fixed the problem (burnt crimp in junction box in the garage) within an hour!! Excellent!

They went above board to make sure every thing was done to perfection !
They give an accurate read on what needs
to be done. They are a safety-first company
that shows up energetic & work...
