Solar design software also determines the effects of different orientations and tilt angles on the performance of the system and global factors like shading losses.Ī key function of solar design software includes the ability to calculate the cost and payback period of residential and commercial projects.Įssentially solar design software help engineers to design efficient yet affordable on-grid or off-grid solar PV systems. It helps in designing the system by determining the size, options, and specifications of the various components in a solar power system such as the solar panel array, PV inverter, charge controller, and battery bank as well as calculating any system losses. They are also used to analyze PV systems’ performance. Solar design software is used for designing and modeling solar photovoltaic (PV) systems. What is solar design software used for? An energy engineer using a laptop standing in between solar panels. So let’s dive into some important information about solar PV design and simulation software and understand a little more about what they are used for, how to choose one, and the key stages in designing PV systems.

That’s why this software is so essential for solar designers, planners, or sales consultants in order to design accurate proposals for potential customers going solar. So we’ve compiled this list of free solar panel energy software, details of their best features, and who they are suited for and to help you choose the perfect design tool for the accurate design and simulation of your projects.Īs a solar power designer, I know how important it is to make systems that are energy-efficient and cost-effective.

While there are many tools available for the design and analysis of solar energy (PV) systems, most of them cost more than $500 USD just for their basic packages. Our team at Engineering Passion has researched solar design software tools that are both free and open-source that can be used to design and simulate residential and commercial solar power systems.
