PV Calculator is a free Android app developed by SusEnergy that helps users to calculate the potential of renewable energy generation in a simple and clear way. The app provides an accurate view of production and battery storage throughout the day, allowing users to design a system adapted to their consumer behavior.

One of the most impressive features of the app is the typical meteorological year (TMY) as radiation data at your site. This hourly resolution offers an accurate view of energy production, and users can define their PV modules and power inverter to calculate the amount of electricity fed into the grid and purchased. Additionally, the app allows users to define their energy demand and daily load profile, sizing of battery storage, roof area measurement, and panel positioning.

The app is easy to use, and its user-friendly interface makes it accessible to everyone. The premium version offers additional features such as historical radiation data, snowfall, shading, and the ability to create an unlimited number of PV arrays.
