In addition to its solar research and development funding programs, the U.S. Department of Energy Integrated Energy Systems Office (IESO) funds prize competitions to encourage innovation and accelerate the development of new solar energy solutions. These competitions inspire a variety of stakeholders to work together to develop new concepts and technologies that can challenge traditional thinking in the solar industry and expand and evolve what’s possible.
The competitions offer cash prizes and expert support to solve challenging, industry-wide problems. They set ambitious goals on a condensed timeline to encourage rapid development, enabling the best ideas to naturally surface and efficiently advance. Competitions also make it easier for new solar innovators to enter the solar market, foster interdisciplinary collaboration, and increase the number and quality of perspectives working to develop solutions.

Solar District Cup
The Solar District Cup, launched in spring 2019, is a multidisciplinary collegiate competition that challenges student teams to design and model distributed solar energy systems for multiple buildings on a local electrical distribution network. The goal is to design, model, and present the most reliable, resilient, cost-effective system possible while preparing students for solar careers. Teams compete in divisions, each with a distinct district-use case and winner, based on the quality of their solar energy system design. The competition is administered by the National Renewable Energy Laboratory.

American-Made Data-Driven Distributed (3D) Solar Visibility Prize – This $175,000 prize competition, announced in May 2024, was designed to incentivize innovators to develop models and algorithms that can provide accurate and real-time information about distributed solar generation in electric power distribution networks. As more solar energy is connected to the grid, utility operators and planners require accurate, real-time information to optimize distributed solar energy resources and enhance the reliability and resilience of the grid. Winners were announced in November 2024.
American-Made Net Load Forecasting Prize – This $600,000 prize competition, announced in February 2023, was designed to increase adoption of the state-of-the-art in net load forecasting by incentivizing forecast providers to demonstrate the quality and performance of their probabilistic forecasting tools to the larger forecasting industry. Winners were announced in September 2023.
American-Made Inclusive Solar Outreach Awards – The American-Made Inclusive Solar Outreach Awards ran from March to September 2022 and sought to recognize effective and inclusive solar industry communications and marketing campaigns. The goal of the was to gather best practices in engaging diverse and/or underrepresented communities about solar energy and its benefits and to share those best practices with others. The Inclusive Outreach Award is now incorporated into the American-Made Sunny Awards for Equitable Community Solar.
American-Made Perovskite Startup Prize – The American-Made Perovskite Startup Prize ran from March 2021 to July 2024 and sought to accelerate the development and manufacturing of perovskite solar cells by moving world-class research out of the lab and into new U.S. companies. The goal was to advance this promising technology and help increase opportunities for U.S. manufacturers by soliciting the talents and innovative spirit of diverse American entrepreneurs.
American-Made SolarAPP+ Prize – This $1 million competition was designed to incentivize local governments to adopt the automated permitting software tool Solar Automated Permit Processing Plus (SolarAPP+) and lower the cost of adoption.
American-Made Solar Data Bounty Prize – This $1.4 million prize competition ran from June 2023 to January 2024 and was designed to increase the accessibility of high-quality time-series datasets for photovoltaic (PV) systems. These types of datasets can be used to build, train, and optimize models designed for PV system simulation, which can in turn provide more accurate performance estimates and better system designs. Improving the accuracy of PV system modeling lowers the risk of developing and operating those assets, which can attract more capital for deployment of PV power plants.
American-Made Solar Forecasting Prize – The American-Made Solar Forecasting Prize was designed to incentivize solar forecast providers to develop and potentially commercialize tools that predict how much energy solar power plants will need to generate days in advance, so grid operators can plan for and manage it.
