Solar panel installation is one of the fastest-growing trades in the country — and one of the most documentation-intensive. Permit requirements, utility interconnection packages, manufacturer warranty documentation, and homeowner education materials all need to come together for a successful installation.
The best app for solar installers in 2026 handles the photo documentation that supports all of that — and helps new clients find you locally. Here's how TimeFotos fits the solar installation workflow.
What Solar Installers Need From an App
- Permit-ready photo documentation — roof condition assessment photos, electrical panel documentation, installation progress photos
- Interconnection package support — photos of completed system for utility interconnection applications
- Manufacturer warranty documentation — installation photos with timestamps for warranty registration
- Client share links — send homeowners their installation documentation package
- Free local listing — get found by homeowners searching for solar installers in your city

Pre-Installation Roof Documentation
Solar installations involve penetrating the roof. If a homeowner has any roof issues after your installation — a leak, a cracked tile, a damaged flashing — they will attribute it to you.
Pre-installation photos of the entire roof surface, all existing flashings, any pre-existing cracks or damage, and the condition of tiles or shingles around the planned installation zone create your baseline documentation. With timestamps and GPS, this documentation is verifiable.
Permit and Interconnection Documentation
Many jurisdictions and utilities require installation photos as part of the permit close-out or interconnection process. Having those photos automatically timestamped and organized by the system address makes assembling the documentation package straightforward.
The Bottom Line for Solar Installers
For solar installation businesses that need permit-ready documentation, installation records, client delivery packages, and local visibility — TimeFotos is built for that workflow.
