Commercial Solar Panel Repair
Mother Nature can take a toll on your solar panels. When wind and weather strike, TENCO SOLAR is there to restore your solar panels to service. We maintain a complete inventory of replacement components, and our expert solar technicians work quickly to get your system back up and running.
We are happy to come out to your business to assess and diagnose your system, and if we cannot repair your system on the spot, we will provide a written quote for the repair cost.
TENCO SOLAR charges a service fee of $285 for a Commercial Solar Service Call. This service fee includes diagnostics, up to one (1) hour of labor, and any small/common parts the technicians have available. We will provide an itemized quote before proceeding if additional time is needed to repair your system and/or additional parts.

Commercial Solar Panel Replacement
Solar panels are strong and resilient, but they can’t last forever. After 25 to 30 years, panels are ready for retirement. When that day comes, TENCO SOLAR will help you identify and install the best replacement available.
Pricing depends on the panels selected, the number of panels being replaced, and whether any additional parts need to be replaced (i.e., inverters, racking, wiring, etc.).
Commercial Solar Panel Maintenance
Solar panels require periodic cleaning and inspection to deliver optimal results. TENCO SOLAR can help you develop and execute a solar system maintenance regimen that will protect your system from damage and preserve efficient operation season after season.

We charge $345 for a Commercial System tune-up, which includes the following:
- Check all strings for proper voltage and amperage

Commercial Solar Panel Monitoring
Proactive maintenance is always better than emergency repairs. At TENCO SOLAR, we can monitor your commercial solar systems for signs of trouble and respond before systems fail. We can maintain hardware, perform software updates, and take other preventative maintenance steps that will help improve system reliability and performance. We will also compile event and performance reports that we can use to track system operation and adjust maintenance schedules.
DIY Vs. Professional Solar Panel Maintenance
While much of what you need to do to maintain your solar panels is something your maintenance team could handle – be cautious! Solar panels often come with warranties, and if you try to DIY your maintenance, you may void the warranty. This risk is not worth taking, so make sure you invest in maintenance with a qualified professional.

Frequently Asked Questions About Solar Panel Repair & Maintenance
Will a solar panel work if it’s cracked?
Solar panels that are not significantly damaged will continue to generate electricity. However, they will not perform as well as panels that are not compromised.
Are damaged solar panels a fire hazard?
They can be, which is why we strongly recommend prompt repairs of any damaged systems. If the wiring is faulty, the insulation is insufficient, or the PV module is compromised, there is a fire risk.
Can solar panels be repaired?
It depends on what part(s) and how much of the panel is damaged. Our team can repair many problems by replacing glass or repairing wiring connections.
How often should solar panels be cleaned?
We recommend scheduling a professional maintenance appointment for a deep cleaning and inspection of their entire solar system once per year.
Can TENCO SOLAR maintain battery backups?
Yes, we can maintain battery backup systems. These systems are integral to the reliable electricity you require, and we can install, maintain, repair, and replace a wide range of battery backup systems in Southern California.
