Solar Installer Toolkit

Solar Installer Toolkit is a complete, offline-first field companion for solar installers, electricians, and small EPC teams — from the first site visit to the final commissioning report. MANAGE YOUR PROJECTS Track every job in one place: customer details, site address, system status, and installation progress, all stored securely on your device. SITE SURVEY & GPS Capture site conditions and tag survey points with GPS coordinates, right from the field. PV SYSTEM DESIGN Record panels, strings, inverter, and battery specs, with quick sizing calculators for solar system sizing, DC/AC ratio, voltage drop, and battery runtime — advisory tools to speed up your workflow, not a replacement for manufacturer specs or a licensed engineer's sign-off. ELECTRICAL MEASUREMENTS Log voltage, current, insulation resistance, and other test readings with full history per project. INSTALLATION CHECKLISTS & GUIDED COMMISSIONING Work through structured safety and installation checklists, then a guided commissioning flow to make sure nothing gets missed before handover. PHOTO EVIDENCE Capture site and panel photos with optional GPS/date/time watermarks. Originals are always kept untouched — the watermark is only burned in if you choose to save a stamped copy. ISSUES & DEFECTS Log issues with priority levels and photos, so nothing falls through the cracks. CUSTOMER SIGN-OFF Collect a customer signature directly on the device to close out the job. REPORTS & EXPORTS Generate professional PDF commissioning reports and export measurements, PV strings, and checklists to CSV — ready to share or archive. BACKUP & RESTORE Back up all your project data to a file and restore it any time. WORKS FULLY OFFLINE No account, no login, no internet required for any core feature. Your project data stays on your device unless you choose to share a report or backup file yourself. Free to use, with occasional banner ads. A one-time "Go Pro" purchase removes ads permanently — every other feature is already free and unaffected by ads. Solar Installer Toolkit is a field documentation and calculation aid. Calculators and sizing estimates are advisory only and don't replace manufacturer specifications, applicable electrical codes, or qualified professional engineering judgment.
