Solopt is a tool that optimizes the mixture of rooftop solar photovoltaic and solar thermal systems. It simulates numerous combinations of both types of systems based on user input to meet user-defined goals such as minimizing levelized cost of energy or maximizing greenhouse gas reduction. With the appropriate input data, the tool may be adapted to markets outside the United States.
