Solarius PV is a dedicated application designed for creating photovoltaic solar grids that can function as the primary energy source for homes and other structures, developed by ACCA software from Italy. It claims to be a complete, easy to use and professional software solution for photovoltaic systems design.

solXpect is a free and open-source photovoltaic system (PV) or balcony PV system output forecast application for Android platform, developed by woheller69 from Germany. It uses direct and diffuse radiation data from Open-Meteo.com, provides precise calculations of the sun's position and projection of radiation onto your solar panel, and takes the shading and temperature coefficient into account.

PVsyst is a famous solar photovoltaic system design software for simulation design and data analysis, developed by PVSyst from Switzerland. As a fully-functional photovoltaic system simulation software, it is able to carry out modeling and simulation of the photovoltaic power generation system, analyze various factors affecting the electric energy production, and finally calculate the generating capacity of the entire photovoltaic power generation system. It is a software package commonly used in the photovoltaic industry for completely researching, measuring, simulating and analyzing the photovoltaic systems.
