Custom solar panel software development
Appfront builds custom software for solar panel and PV installation companies: from lead and quote, with roof scan and indicative yield calculation, through configuration of panels and inverters, scheduling of installation crews, work orders and handover on site, stock and purchasing, grid operator registration, monitoring, aftercare and invoicing. Everything in one file per customer and per installation, aligned with your own calculation and installation process. For installers who want sales, installation and administration to run as one continuous line.
What is solar panel software?
Solar panel software supports the entire process of a PV installation company: from the incoming lead and quote, including roof scan and yield calculation, through configuration of panels, inverters and mounting materials, to scheduling installation crews, work orders and on-site handover, stock and purchasing, grid operator registration, monitoring and aftercare, and invoicing. Everything comes together in one file per customer and per installation, so sales, fitters and the office all work from the same up-to-date picture.
Off-the-shelf packages often cover part of this process, but they force your costing and installation into a fixed shape. Solar installers differ greatly, however: in how quotes and yield calculations are produced, in which panel and inverter brands are standard, and in how scheduling, handover and aftercare are organised. Custom software fits your process rather than the other way round, and stops you working with separate spreadsheets, a standalone calculation tool and an accounting package that don't talk to each other.
By bringing sales, job preparation, installation and administration into one system, every step becomes traceable and nobody has to retype data. Also see our broader approach to custom software and, for installers who go beyond PV alone, our installer software.
One file per installation
Lead, quote, configuration, scheduling, work orders, handover and aftercare in one coherent file per customer and per installation. Sales and fitters work in one place, without copying data across separate systems.
From quote to installation
An accepted quote flows through to job preparation, materials and scheduling. The configuration of panels and inverters determines the bill of materials, so the crew on site knows exactly what needs to be installed.
Traceable through to handover
Photos, meter readings, serial numbers of panels and inverters, and the customer's signature are recorded at handover. This gives you a complete handover file and a foundation for warranty and aftercare.
How we build your solar panel software
We work step by step and involve your sales, job preparation and installation crews early in the project. From a thorough review of your costing and installation process through to go-live and ongoing management, every step is aimed at software your team understands, trusts and can use daily in the office and on the roof.
We map out your process: from lead and quote, through configuration and scheduling, to installation, handover, aftercare and invoicing. Together we determine which functionality and integrations matter most and where the greatest time savings lie.
We design the case model, the configuration logic for panels and inverters, and a work order that works well on site, plus the approach for integrations with your accounting, suppliers and payment services.
We build in short iterations with automated tests and monitoring. You see working versions along the way and test them with sales and fitters, so the software fits everyday practice.
Controlled go-live with data migration and a safety net, followed by ongoing management, monitoring and further development as your range, your team or the regulations change.
What solar panel software actually does
We tailor every application specifically to your range, your costing and your way of installing. Below are the functionalities we most often deliver for solar panel and PV installation companies.
Leads & quotes
Incoming enquiries become a lead with roof situation, wishes and contact moments. From the configuration you put together a quote with versions and approvals, so sales and job preparation always work from the same starting points.
Roof scan & yield calculation
Check the roof situation and produce an indicative yield estimate based on roof surface, orientation, pitch and number of panels. The customer receives a well-founded picture; the final output depends on the site survey and local conditions.
Panel & inverter configuration
Build up installations from panels, inverters, optimisers and mounting materials. The configuration determines the bill of materials and the price breakdown, and ensures the right materials end up on the job sheet and in purchasing.
Scheduling & job sheets
Schedule installation crews based on signed quotes, materials and region. Crews work on site with digital work orders and record photos, meter readings, serial numbers and a signature on completion.
Stock & purchasing
Keep track of stock of panels, inverters and mounting materials and raise purchase orders based on planned projects. This way you avoid a crew standing idle at the door because material is missing.
Monitoring, aftercare & invoicing
Keep track of warranties, serial numbers and maintenance agreements, schedule aftercare and fault visits, and invoice deposits and final statements. Signals from yield monitoring can come in as service alerts for proactive contact.
For whom we build solar panel software
Solar panels are supplied by a wide range of companies, each with its own position in the market. For each of them we build software that suits their offering, their team and the way they sell and install.
Solar panel installers
Companies focused entirely on selling and installing PV systems for private and business customers, with their own installation crews and a tight costing and handover process.
PV installation companies
Larger PV companies working with multiple crews and sometimes several branches, who need control over scheduling, materials and handover across the entire chain.
Sustainability companies
Companies that combine solar panels with other measures such as heat pumps, insulation or EV charging points, and who want to manage the PV part in the same software as the rest of their projects.
Energy installers
Installation companies that offer PV as part of a broader energy and installation service and want the costing, scheduling and aftercare of solar panels to fit their existing way of working. See also our installer software.

We build with a modern, maintainable web stack and integrate where it adds value. For solar panel installers, the most relevant are: an integration with your accounting or invoicing package, with suppliers and wholesalers for pricing and stock, with payment services such as iDEAL for deposits, and preparing installation data for registration via the energieleveren.nl register. We set up each integration with a clear purpose, so data is recorded once and then flows automatically between sales, installation and administration. For broader scheduling challenges, we combine this with our custom planning and scheduling software.
Why choose Appfront for your solar panel software?
Appfront builds custom software and always begins with a thorough analysis of your process, your range and the way you install. Software for a PV installation company must not only work in the office, but also work well on the roof, where fitters in gloves and in the sun need to be able to complete a job sheet.
We write clear documentation and deliver transparent code, so that your own team or a future supplier can understand and manage the software. No black box, but clear agreements on integrations, authorisation and management, so you are not tied to a single supplier.
You work with a fixed point of contact who understands both the technology and the installation practice. This keeps lines short, prevents miscommunication and speeds up decisions when choices need to be made during the build.

Security and privacy in solar panel software
A solar panel installer handles customer data, addresses, photos of homes and payment details. That is why we build with security and privacy as a starting point. We apply data minimisation, set up role-based authorisation so that a fitter sees different data from the back office, and record access and changes where traceability is required.
We build in line with the GDPR, with encryption in transit and at rest, secure handling of payment data through certified payment providers, and clear agreements on backups and management. This way you handle customer and installation data carefully and remain demonstrably in control, without the software collecting data it does not need.
Read more about our security approach: information security policy and vulnerability disclosure policy. Discuss your situation without obligation via our contact form.
For large-scale PV, insurers almost always require periodic inspection of the installation. What that involves and how you record it on the roof is set out in SCIOS scope 12.
- GDPR-compliant data processing and data minimisation
- Role-based access for sales, fitters and administration
- Encryption in transit (TLS 1.2+) and at rest
- Secure payments through certified payment providers
- Careful handling of address and home photos
- Logging of access and changes where needed
- Clear agreements on backups, hosting and management
- Documentation so you avoid vendor lock-in
Frequently asked questions about solar panel software
Answers to the questions we are asked most often about custom software for solar panel installers.
Solar panel software supports the entire process of a PV installation company: from an incoming lead and quote, including a roof scan and yield calculation, through to configuring panels, inverters and mounting materials, scheduling installation crews, work orders and on-site handover, stock and purchasing, grid operator notifications, monitoring, aftercare and invoicing. Custom software lets you set this up the way your own calculation and installation process works, rather than forcing your way of working into a standard package. Everything comes together in a file per customer and per installation, so sales, fitters and the office all work from the same up-to-date picture.
We build custom software. Solar panel installers differ greatly in their approach: how quotes and yield calculations are prepared, which brands of panels and inverters are standard, how installation crews are scheduled, and how handover and aftercare are organised. Custom software fits your actual process and can grow as your product range, your team or the regulations change. After an intake meeting, we decide together which functionality matters most and in what order to build it, without promising a fixed lead time or price that we cannot yet substantiate.
From a lead, you record the roof situation, choose a panel and inverter configuration, and put together a quote based on it. An indicative yield calculation takes into account the roof area, orientation, pitch and number of panels, so the customer gets a well-founded picture of the expected output. The calculation is qualitative and indicative: the exact yield depends on the final survey and local conditions. Quotes, versions and agreements remain stored in the customer file, so sales and installation planning always work from the same starting points.
Yes. You schedule installation crews based on a signed quote, material availability and region. Crews see their assignments, addresses and the materials they need, and work on site using digital job sheets. On handover, they capture photos, meter readings, serial numbers of panels and inverters, and the customer's signature. This way, job preparation, execution and handover form one continuous flow, and nobody has to re-enter data. For broader planning challenges, we can combine this with our custom planning and scheduling software.
Commonly requested integrations are those with your accounting or invoicing package, with suppliers and wholesalers for pricing and stock of panels, inverters and mounting materials, and with payment services such as iDEAL for deposits. For customer identity, KvK data can be retrieved. We set up each integration with a clear purpose, so data is recorded once and then flows automatically between sales, installation and administration. Together we determine which integrations genuinely add value to your process.
A new PV installation must be registered, including through the national register energieleveren.nl run by the grid operators. The software can support this process in an indicative way by gathering and preparing the required installation details, such as capacity and location, in a structured manner, and by tracking per installation whether registration has been completed. We align the exact approach with the current requirements of the grid operator and your internal process. The software does not take over your administrative responsibility, but it does make that responsibility clear and traceable.
Yes. After handover, you keep track of warranties, serial numbers and maintenance agreements for each installation. Aftercare reports and faults come in as service requests and are scheduled as maintenance visits, using the same job sheets as for installation. Where you or the inverter manufacturer use yield monitoring, we can have deviations come into the software as signals, so you can proactively contact the customer. This keeps the customer file complete and usable for service and repeat sales even after installation.
We build for solar panel installers, PV installation companies, sustainability firms that combine solar panels with other measures, and energy installers who offer PV as part of their service. The software supports sales and cost calculation, installation crews on site, and back-office administration, and it grows with you from a small team to multiple crews and branches.
