SOLAR PROJECT WORKSPACE

Create grid-tied, hybrid or off-grid solar projects. Enter module, string, inverter and production values, then review array power, annual energy estimate, DC/AC ratio and design consistency checks.

Save calculator results inside projects and keep related calculations together.

REPORTS AND BACKUP

• Export project reports as PDF
• Export calculation data as CSV
• Create and restore JSON backups
• Share files through the standard iOS share sheet

PRIVATE AND OFFLINE

PVLedger does not require an account, login or internet connection. The app contains no advertisements, subscriptions or in-app purchases. Calculations and project data are processed and stored locally on the device.

Editable regional profiles for Europe, Türkiye, the United States and China provide convenient starting values.

IMPORTANT

PVLedger is a preliminary engineering design and calculation aid. Results must be verified using actual site conditions, manufacturer documentation, structural requirements and applicable local electrical regulations. The app does not replace professional engineering approval or regulatory certification.
