Solar Spotter – PV Calculator is an app that calculates the optimal orientation and inclination of a solar photovoltaic (PV) system. It is useful for any location, even if you don't have a solar panel. The app uses information about the location and the angle of the sun to determine the best time to install the PV system.

You can also calculate the power generation capacity of the system and the cost of the installation. The results are presented in a simple and intuitive way, so even if you have no knowledge about solar energy, you can use the app and understand the information presented in a few minutes.
