How SolairTech secured its field rounds and photovoltaic inspections with energy maintenance scheduling software

Before Cadulis, technical rounds at SolairTech sometimes felt like a poorly marked treasure hunt. Between makeshift Excel schedules, photos shared via WhatsApp with no captions, and technicians having to turn back before even reaching their intervention site... let’s just say optimization was not exactly on the agenda.

A demanding sector, very real constraints

SolairTech operates in one of the most crucial sectors of our time: installation and maintenance of photovoltaic and thermal systems. But their activity doesn’t stop there. With certified electricians, they also handle the installation of charging stations for electric vehicles—a booming field.

With 22 field technicians, 2 maintenance coordinators, and one operations manager, operational rigor is a must. However, maintaining this rigor became difficult as business grew.

“We were always chasing information. Photos were coming in randomly, with no idea which site they belonged to. And the schedule? Sometimes it was a lottery.”
— Julien P., Operations Manager at SolairTech

The limits of “homemade” organization

An endlessly long Excel file
Rounds assigned manually by the manager
No consideration for travel times or customer hours
Technicians sometimes covering an entire region for... not much
Reporting closer to a hunt for inconsistencies than a management tool

Implementing energy maintenance scheduling software

The adoption of Cadulis was quick. Two weeks were enough to set up the tool, configure the modules, and connect existing systems, without disrupting operations.

Modules activated at SolairTech:

Smart scheduling based on site type, geography, and skills
Custom forms for photovoltaic inspections, heat pump maintenance, and thermal monitoring
Automated PDF reports: customer signature, photos, anomalies, timestamps
Synchronization with the internal energy supervision tool
Offline mode for remote areas

For example, forms were enhanced with a QR code scan field. Each component of an installation is automatically identified, with its model and serial number. Result: ultra-reliable equipment tracking, easier stock management, and exemplary traceability.

Concrete and fast results

100% of rounds scheduled in Cadulis
85% of reports sent within 2 hours after the intervention
+60% visibility on actual site performance
Zero missed field feedback thanks to guided forms
-40% time spent consolidating weekly reports

The manager was able to refocus on the company’s strategic development. No more last-minute juggling to assign unrealistic rounds.

“Interventions can now last as long as planned. Travel times are taken into account, technicians are less stressed. And the manager... sleeps better.”

Before / After: a whole new ballgame

Aspect	Before Cadulis	After Cadulis
Scheduling	Manual Excel, poorly optimized	Automated, algorithm-optimized
Field feedback	WhatsApp, unidentified photos	Guided forms with photos and scan
Reporting	Long, tedious, unreliable	1 click, fresh and reliable data
Traceability	Low, poorly tracked interventions	Timestamping + geolocation
Maintenance tracking	Manual, often forgotten	Automated from installation

The power of good energy maintenance scheduling software

A good tool doesn’t just help. It transforms. By adapting to what’s already in place, speaking the technicians’ language, and making scheduling as simple as an Excel filter, Cadulis put things back in order.

Main benefits observed:

Structured, real-time monitoring of photovoltaic production
Flawless traceability of field operations
Proactive management of periodic maintenance
Improved service quality for end customers
Calm technicians, focused on their core business

For technicians: simplicity and immediate adoption

No need for lengthy training. The tool was mastered in just a few minutes. Why? Because it uses industry vocabulary and field logic. The interface is designed for them, not against them.

Managing scheduled maintenance

For each installation, control interventions are created in Cadulis with a dedicated time window. These maintenances automatically appear in the list of interventions to be scheduled. Result: they are carried out on time and optimized within the rounds.

Smooth integration with internal tools

Synchronization with the energy supervision tool required only simple data mapping via API. Cadulis adapted quickly to the existing environment, without forcing a reset of internal processes.
