8 cool FREE design tools for solar energy systems

https://cleanenergy4africa.org/8-cool-free-design-tools-for-solar-energy-systems

In the following list, I have compiled 8 FREE software and online design tools for on-grid and off-grid solar systems design. PVWatts (developed by the National Renewable Energy Laboratory NREL) is a great and easy-to-use online tool for estimating the energy yield of grid-connected PV systems anywhere in the world. SAM (or System Adviser Model) is another software developed by NREL and is probably the most complex in this list. SAM is used to model the technical performance of several renewable energy system and evaluate economic and financial feasibility. SISIFO is an online design tool developed by the Solar Energy Institute of the Universidad Politecnica de Madrid and is used for the simulation of on-grid PV systems and also irrigation systems powered by PV panels. PV\*SOL online, developed by Valentin Software, is a web version of the famous PV\*SOL software and is used for the design and simulation of PV systems.
