Renewable energy is a fundamental way to mitigate climate change, because the accelerated development of sustainable energy technology is relevant to replace conventional energy sources. A renewable energy source is solar energy that harnesses sunlight to produce electricity through solar panels. However, in the installation of a solar panel system, the design of the system is often not taken into account, so the maximum performance of the system is not used. Therefore, the purpose of the research was to develop software for the design of solutions with solar panel systems. The type of research was qualitative and applied, with action research design and practical approach. As a result, software was obtained to design a solution of a solar panel system that allows to take advantage of the maximum performance of the system to be installed.
