About this app

THE FUTURE IS SOLAR ENERGY. MAXIMIZE YOUR PLANT'S YIELD.

Photovoltaic Calculations is the ultimate app for industry professionals, installers, and renewable energy enthusiasts. Design, size, and analyze every aspect of your solar plant with precision and speed. Get the most out of your solar panels by optimizing every single component simply and instantly!

MAIN CALCULATIONS AND SIZING:
✓ Photovoltaic panel yield
✓ Air mass index and fill factor
✓ Sun position and optimal tilt angle
✓ Irradiance on a tilted surface
✓ Solar cell temperature and temperature effect on the module
✓ Integrated tools: compass, inclination, altitude
✓ Solar cable ampacity and cross-section calculation (DC)
✓ Protective device sizing and SPD (Surge Protection Device) requirements
✓ String sizing and short-circuit currents
✓ Ideal inverter selection
✓ Photovoltaic panel decay over the years
✓ Occupied surface area and spacing between module rows
✓ Estimation of daylight hours during the year

THEORETICAL AND PRACTICAL RESOURCES:
✓ Series and parallel panel connections
✓ Basic concepts: module, string, and photovoltaic array
✓ Astronomical parameters: solar zenith, solar azimuth, solar declination

Everything you need is packed into an intuitive interface, which also includes a VERY USEFUL FORMULARY always at your fingertips.
Do not leave efficiency to chance, start designing your perfect solar plant today!

What’s new

v3.3.0
* Mod: Calculations reordered based on their usage
* Mod: Updated all references to the 2026 NEC
* Upd: Added icons to the menu items
* Fix: After a search the tab bar remained hidden
* Fix: Air mass index: the angle field is now called "Solar elevation"
* Fix: Fill factor: an error message is now shown when the entered values are inconsistent
* Fix: Sun position: latitude, date and time are no longer lost or replaced after rotating the screen
