Repair and modernization of a solar installation with 55 panels near Roquefort les pins, Le Rouret and Opio



In the area of Le Rouret, Opio, Roquefort-les-Pins, Mouans-Sartoux and Grasse, many homes installed photovoltaic systems several years ago. Unfortunately, when problems appear, some installers are no longer available to maintain or repair the systems.

This was exactly the situation for this homeowner.

The property was equipped with 55 photovoltaic solar panels, installed a few years earlier by another company in the region. When technical issues started to appear, the original installer was no longer responding.

As a result, a large part of the solar installation had stopped producing electricity properly.

The homeowner contacted REGIS ELECTRIC, a solar and energy systems specialist based in Valbonne, to diagnose the installation and restore the system.

REGIS ELECTRIC regularly performs solar system repairs, upgrades and battery installations across the French Riviera, particularly in:

  • Le Rouret

  • Opio

  • Roquefort-les-Pins

  • Mouans-Sartoux

  • Grasse

  • Valbonne

  • Mougins

  • Antibes

  • Cannes

Complete diagnostic and restoration of the solar installation

The first step was to perform a complete technical inspection of the photovoltaic system.

During the diagnostic process we identified several issues:

  • multiple solar panel strings were no longer operational

  • the energy management system was fragmented and inefficient

  • the installation was not prepared for energy storage or backup power

Our objective was therefore to restore the entire solar production while modernizing the system architecture.

The work included:

  • restoring the full operation of the 55 photovoltaic panels

  • simplifying the electrical structure of the installation

  • preparing the system for battery storage and energy autonomy

The goal was to transform an aging solar system into a modern, reliable and future-ready energy system.


Installation of a Sigenergy SigenStor system – the most advanced solution for home energy autonomy


To modernize the installation, we installed a Sigenergy SigenStor energy system.

Sigenergy is currently one of the most advanced energy systems available for residential solar installations, particularly for homeowners looking to increase energy independence and resilience.




The SigenStor system integrates several essential components into one intelligent platform:


  • photovoltaic inverter

  • modular battery storage system

  • intelligent energy management

  • backup power in case of grid outages

  • integration with a backup generator if needed

  • smart monitoring via mobile application


Unlike many older solar installations where multiple devices operate separately, the Sigenergy system centralizes all energy management into one unified platform.


This approach provides several advantages:

  • a simpler and cleaner installation

  • improved reliability

  • easier monitoring and maintenance

  • a system designed to evolve toward full home energy autonomy


Centralized energy management for the entire solar installation


The 55 photovoltaic panels are now managed by the Sigenergy system.

This centralized architecture allows:

  • optimized solar production management

  • real-time monitoring of the installation

  • intelligent distribution of energy within the house

The system is also ready for future upgrades such as:

  • additional battery capacity

  • integration of new energy sources

  • transition toward energy-autonomous homes


Integration with MyLight virtual battery


In addition to the physical energy system, the homeowner also uses a MyLight virtual battery service.

A virtual battery allows solar energy produced in excess to be injected into the grid and stored as energy credits, which can later be used when the house needs electricity.


By combining:


  • solar production

  • Sigenergy intelligent energy management

  • MyLight virtual battery storage

the homeowner can maximize the value of their solar energy production.


A modern solar installation ready for the future


Thanks to this intervention, the property now benefits from a fully restored and modernized solar installation.

The system is now:


  • fully operational

  • simplified and centralized

  • equipped with advanced energy management

  • ready for energy storage and future upgrades


Across the French Riviera, many older photovoltaic installations can benefit from similar upgrades.

With modern systems such as Sigenergy SigenStor, it is now possible to transform traditional solar installations into intelligent energy systems capable of powering homes more independently.

FAQ – Solar repair and battery systems on the French Riviera


Can you repair a solar installation installed by another company?


Yes. REGIS ELECTRIC frequently performs diagnostics, repairs and upgrades on solar installations originally installed by other companies. Many systems can be restored and significantly improved.


Why install a Sigenergy system?


Sigenergy SigenStor systems are among the most advanced residential energy platforms available today. They combine solar inverter, battery storage, intelligent energy management and backup capability in one integrated system.


Can batteries be added to an existing solar installation?


Yes. In many cases it is possible to add battery storage to an existing photovoltaic installation. This increases self-consumption, reduces dependence on the grid and provides backup power.


What is a virtual battery?


A virtual battery stores excess solar production as energy credits on the grid. The homeowner can later use these credits when electricity consumption is higher.


Where do you provide solar services on the French Riviera?


REGIS ELECTRIC works across the French Riviera, including:


  • Le Rouret

  • Opio

  • Roquefort-les-Pins
