Solar Pv Optimal Spot, developed by Simone Rizzo, is a free Android application in the Utilities & Tools category. This app uses the API provided by PVGIS to guide the user in finding the optimal inclination and orientation for their solar and PV panels. The app provides daily mean data of irradiance and power through smart graphs, which can be used for scientific and engineering analysis.

The app has a clear tutorial that explains the app structure. It calculates the optimal inclination and orientation for the entire year, along with the daily mean power developed by crystSI PV technology, CdTe PV technology, and CIS PV technology. It also calculates the daily mean irradiance on a well-oriented panel. The interactive daily mean power and irradiance charts are useful in analyzing the data. Additionally, the app provides a detailed explanation of the physics model and calculations used by PVGIS to calculate app parameters.

Overall, Solar Pv Optimal Spot is a powerful tool for those who want to optimize the position of their solar and PV panels. The app's simple and optimized design makes it easy to use, and the data provided is accurate and relevant for scientific and engineering analysis.
