Electrical and Solar Help for San Jose Homeowners
Dollens Electric is a local residential electrical and solar contractor. We diagnose, repair and modernize the systems that power the home — including electrical panels, wiring, existing solar, inverters, EV charging and backup power.
Because these systems often affect one another, we look at the home as a whole before recommending what should be repaired, replaced or upgraded.

Not Sure Which Service You Need?
Start With What Is Happening
You do not need to diagnose the problem before contacting an electrician. Choose the closest match and we will help determine the right starting point.
One Home. One Electrical System.
Electrical, Solar and Backup Power Affect Each Other.
Solar, batteries, EV chargers, electrical panels and home wiring do not operate independently. A battery may depend on the inverter and panel. An EV charger may change capacity needs. A solar production problem may actually be a breaker, wiring, monitoring or inverter issue.
Dollens Electric brings electrical and solar knowledge together so we can look at the full system and explain what needs attention — and what can stay exactly as it is.
Repair what makes sense. Upgrade what needs it. Don't replace equipment just to sell equipment.

Common Questions
Electrical & Solar Service FAQs
Can Dollens Electric repair solar installed by another company?
Yes. We service and troubleshoot existing residential solar systems, including orphaned systems and systems installed by another contractor. We can evaluate production, inverters, monitoring, breakers, disconnects and accessible solar-related electrical components.
Do you perform 200A and 400A electrical panel upgrades?
Yes. We evaluate the existing electrical service, current loads, planned equipment and utility requirements before recommending the appropriate panel or service upgrade.
Can I add a battery to an existing solar system?
In many cases, yes. Compatibility depends on the existing solar equipment, inverter, electrical panel, available space, utility requirements, household loads and your backup goals.
Do you handle permits and inspections?
For work that requires permitting or inspection, Dollens Electric coordinates the electrical scope and applicable permit, inspection and utility steps as part of the project process.
What if I am not sure which electrical service I need?
You do not need to diagnose the issue yourself. Tell us what is happening in the home and we can help determine whether the right starting point is troubleshooting, an inspection, solar diagnostics, panel evaluation or another service.
