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.

I like the app but some of the language should be more consistent with the NEC. Perhaps the developer is IEC based in which case I apologize, but let's call a PV output circuit feeder what it is defined as by the NEC 690 definitions not a sub array cable. I design solar for a living but can't make any use out of the fuse sizing tool. Easier to do with a normal calculator. Rooting for the devs here and like a lot of what this app offers. Just want to see it be even better.
