CALO.SOL & MightyFields
How CALO.SOL Became the Ultimate Choice for Subcontractors in One Month
CALO.SOL GmbH is a multi-awarded company for solar system solutions. They provide turnkey solar power solutions for residential clients across Germany.
Challenge
Winning the race for quality subcontractors
Since CALO.SOL has grown a market reputation in Germany, and it is trusted with more and more projects. And to meet market needs, subcontracting teams are crucial to managing the installations.
Before introducing MightyFields Solar, CALO.SOL used different communication channels (email, WhatsUp, phone calls, …) to empower the office and subcontracted teams with all the needed project information to plan, track, and complete the installations. As a result, the teams were losing time for administration, information got lost (or incomplete), and eventually, the same team could complete fewer projects.

Solution
Scheduling app for real-time work planning
CALO.SOL gained the capability to plan, distribute, and track the installation jobs of their subcontracted teams all across Germany. Subcontractors can access their daily/weekly/monthly calendar with all the job details to plan their workday efficiently and always come prepared to the location. If there is any update on the specific job, subcontractors are instantly notified without additional communication (emails, phone calls, etc.) with CALO.SOL’s planning team.
“With MightyFields Solar, it is easier to plan projects, and we can finish them faster.”
Andrea Kehl, Head of project management
Controlled quality and efficiency with the guided process
With MightyFields Solar mobile app, subcontractors get information on what needs to be done and which information they need to collect to complete the job. Given the job specifics, they are guided through which data, pictures, signatures, and checklists they need to collect. CALO.SOLs’ and subcontractors’ teams save time collecting the information days/weeks after the job is finished. As a result, the billing cycle has been shortened by 85%.
“Prior MightyFields Solar, we need to send up to ten emails to subcontractors to get all the data. Besides losing precious time for communication, it directly affected the billing cycle. With MightyFields Solar, we have shortened the billing cycle from one or two weeks to one or two days which is excellent for us and our subcontractors.”
Andrea Kehl, Head of project management
The solution, straightforward to use
One of the critical factors when introducing a solution is that it is simple to use. Subcontractors started using the mobile app and recognised added value instantly. They can download the app from the Google market/iOS app store and are ready to go. CALO.SOL, on the other hand, can administrate all the work, access the data and modify the workflows/content on their own to respond to business needs quickly.
“MightyFields Solar is straightforward to use. Subcontractors love the mobile app because they have all the information available, do not lose time for administration and get paid for the job much faster.”
Jakob Halbauer, Business process analytic and ICT administrator
“MightyFields Solar allowed us to quickly streamline our processes and ensure consistency in quality across every project, team, and team member. The solution is very well-defined; however, the best part is that it allows instant customizations of the captured and reported data.”
Katerina Božič, Ph.D.,Chief Strategy Officer

"With the introduction of MightyFields Solar, we could standardise the processes and workflows. My biggest benefit is that I do not need to be involved in day-to-day operations and can now focus more on strategic activities to provide the best services for our clients and partners."

Stefan Arnold, Managing Director at CALO.SOL GmbH

Issue tracking made simple
How do you deal with the issues at your construction sites?
Imagine your site managers being able to report identified issues directly via a mobile app. Once the issues are reported, you can manage them in one system and track all the detailed information about your installation sites and maintenance of power plants in one place.
Here is how to never miss an issue and solve them all 25% faster
You’ll never miss one issue!
Both your office and your field teams will have real-time information on the status and details of every issue that concerns them.
Once the issue is reported (from the office or from the field), you can schedule its resolution (in the office), resolve it (in the office or in the field), and close it, meaning you confirm the resolution by closing the issue in the office.
Every issue will have all the detailed information, with reports available in chronological order. You can use them to overview all the activities made at the site or, more importantly, to prove work once the issue repeats or needs detailed analysis.
So you can always be sure that all the issues will be resolved. Not only the critical ones.

You’ll solve issues 25% faster!
There will be no talking or discussing the process, just work and meaningful conversations with the aim of solving the issue.
With just a few clicks, in a few seconds, your team members can report, schedule, and report about the resolved issue.
Reporting can include all the information you might need—from the issues’ micro-location, photo/video materials, detailed description, severity rating, or any other relevant information—to support your team in having an issue log empty.
Automated workflows and clear communication will help you resolve issues up to 25% faster. Mighty!

By integrating compliance into everyday work, these tools empower field teams to focus on productivity while maintaining high safety standards.
Improving Safety Across Renewable Energy Sites
Safety is critical in renewable energy operations, where risks such as high-altitude work, electrical hazards, and extreme weather are common. Hands-free solutions provide:
- Voice-Guided Safety Checks: Workers can follow step-by-step instructions to ensure all procedures are followed.
- Instant Access to Emergency Protocols: In critical situations, safety measures can be retrieved with a simple voice command.
- Real-Time Alerts: Escalate hazards or compliance breaches instantly, ensuring rapid responses.
With compliance and safety integrated into daily workflows, renewable energy teams can reduce incidents and avoid costly liabilities.
Measuring the Impact of Compliance Integration
For a renewable energy company with 50 fieldworkers, integrating hands-free solutions can deliver significant benefits:
- Fewer Safety Incidents: A 20% reduction in incidents can save thousands in liability costs and downtime.
- Improved Compliance Reporting: Accurate, real-time data simplifies audits and reduces the risk of regulatory fines.
