PV Installer Pro

You're on the client's roof. The installation is ready, it's time for the report. You pull out your phone, go through the guided steps, collect photos and signatures, and the PDF is ready before you even get off the ladder. That's how PV Installer Pro works.

One app instead of a binder, calculator, spreadsheet, and notebook.

PV Installer Pro is a professional tool for photovoltaic installers. Energy yield and electrical calculators, battery storage sizing, compliance checks, acceptance protocols, and project management—all in one app. Works fully offline, with cloud sync for signed-in users.

━━━ CALCULATORS ━━━

▸ PVGIS CALCULATOR
Calculate annual energy yield using the PVGIS database (European Commission). Enter GPS location or address, installation power, tilt angle, azimuth, system losses, energy price, self-consumption, and export rate. The result: production forecast, monthly breakdown, 3 payback period variants, and a 25-year savings projection with degradation.

▸ BATTERY STORAGE SIZING
Size the recommended BESS capacity based on PV yield, self-consumption, tariff, and energy profile. Compare payback with and without storage, estimate self-consumption increase, and check the formal classification of the storage system.

▸ ELECTRICAL CALCULATOR
Selection of DC/AC cables and protection devices according to IEC 60364-7-712. String configuration, Voc check at minimum temperature, voltage drop, thermal derating for DC cables, and RCD type selection based on inverter parameters. Recommendations include fuses, DC disconnect switch, SPD, MCB, and CSV export.

▸ COMPLIANCE CHECKER
Verify the installation against the active market rules. The app supports market-specific rule sets for Poland, Germany, Spain, the United States, and Japan, with HARD, SOFT, and ADVISORY checks for subsidy, formal, and technical requirements.

━━━ ACCEPTANCE PROTOCOLS ━━━

Commissioning protocol generator in a guided step-by-step flow:
