About this app

Developer Description

Many calculations related to the photovoltaic sector in one app!

Photovoltaic systems represent the future, this app brings together simple and quick calculations to make the most of solar energy.

Main:
Efficiency of solar panels, Air mass coefficient, Fill factor, Sun position, Optimal tilt angle, Solar radiation on a tilted surface, Solar cell temperature, Effect of temperature on the photovoltaic module, Compass, Tilt, Size of the solar cable (DC), Protection device sizing, String sizing, Short-circuit current of strings, Choice of inverter, Decay of photovoltaic panels over the years, Occupied surface, Hours of daylight during the year.

Resources:
Series solar panels connection, Parallel solar panels connection, Module - string - array, Solar zenith, Solar azimuth, Solar declination.

The app also contains a very useful form.

Really useful calculating array fusing requirements according to the IEC standards.

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.
