The Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of the Solar Energy Technologies Office (SETO), a Funding Opportunity Announcement (FOA) entitled ?SunShot Incubator Round 10, SolarMat Round 3, SunPath Round 2?. This FOA will enable the widespread market penetration of highly impactful solar technologies and solutions through technology research, development, and demonstration to overcome technical, institutional and market challenges. Historically, annual funding opportunities have been separated by stage of technology development (Incubator, SolarMat, and SUNPATH). In the interest of optimizing the application and selection process, these funding opportunities have been combined into a single FOA, with the goal of bringing disruptive innovation to the solar industry in the near term that will take root in the U.S. The total federal funding will be approximately $45M with a 20% to 50% awardee cost share required depending on the project Tier. Projects are expected to be funded with a maximum award level of $500,000 to $10M depending on project Tier. This FOA has 5 Tiers based on the type of product (hardware or non-hardware) and product maturity.
