Household Savings

SETO’s investments in photovoltaic (PV) technologies have helped make solar panels more efficient, cost-effective, and durable, helping households save money with solar energy. SETO funds research to maximize the amount of electricity generated over the course of a PV module’s lifetime, making rooftop solar more effective at generating power and therefore a more worthwhile investment. As solar panels have become more efficient, they also have become more durable. SETO programs like the Durable Module Materials Consortium (DuraMAT) are hastening the development and deployment of strong, high-performance PV materials that lower the cost of electricity generated by solar power and extend solar panel lifetimes. Additionally, SETO-funded researchers are ensuring that PV materials can withstand decades of wind exposure, precipitation, extreme temperatures, and other intense conditions, so solar panels can keep generating affordable electricity for households.

Economic Opportunities

SETO’s investments in solar energy innovation support economic growth by providing innovators with the seed money needed to launch successful businesses that generate economic opportunities. Funding opportunities, such as SETO’s Incubator program and Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) program, have invested hundreds of millions of dollars in startup technologies, which have generated nearly $11 billion in follow-on investments. SETO’s American-Made Solar Prize has helped many innovators reach their goals and build momentum in the solar market. In total, American-Made Challenges have distributed more than $100 million in cash prizes that help transform innovative ideas into thriving businesses that grow and modernize the solar industry while generating economic opportunities for individuals and communities.

Grid Resilience and Reliability

Years of SETO-funded research and development efforts with universities and national laboratories have generated foundational knowledge from which many modern innovations are developed. SETO collaborations are giving us a better understanding of how to use solar technologies in a safe, reliable, and cost effective way while awardees, such as Fend Incorporated and Operant Networks, are helping to protect the U.S. grid from hacks while incorporating distributed energy resources (DERs) into the system.   

Solar-plus-storage innovations stabilize the grid with energy reserves that help utilities accommodate peak energy demand and maintain power in the case of grid interruptions. Hardware innovations, like Quest Renewables’ (2020 Phase II), are making solar energy systems more resilient to natural disasters to provide regions impacted by intensifying weather patterns with a consistent clean power source. SETO’s investments in solar energy innovations are helping to secure the power grid and keep the lights on across the country.

Owning your Power Production

Solar energy innovations are working to make technologies cost-effective, affordable, and accessible to more people. Not everyone can install rooftop solar, which is why SETO funds innovations like Gismo Power’s (2022 Phase I). It gives people the opportunity to own their power production regardless of the roof over their head. SETO awardee, Sun Number, partnered with real estate company Zillow, making it that much easier for homeowners and prospective buyers to begin the journey of owning their power production with residential rooftop solar.

Building-Integrated PV (BIPV) innovations are also helping expand options for Americans. SETO awardees Toledo Solar and Other Lab (2021 Phase I) are driving innovations in U.S. BIPV manufacturing with low-cost, high-efficiency solar windows, facades, rooftop modules, and specialized roofing panels that reduce installation and contractor costs.

Environment

SETO funds research to develop new materials and designs that can make PV products longer-lasting, less energy-intensive to produce, and easier to recycle. SETO’s investments in PV end-of-life management led to the development of a Photovoltaics End-Of-Life Action Plan that outlines a five-year strategy to establish safe, responsible, and economic practices for solar module and system component waste.

SETO also supports innovative projects that help build pollinator-friendly ecosystems under and around solar arrays. Other SETO programs, such as Innovative Solar Practices Integrated with Rural Economies and Ecosystems (InSPIRE), Foundational Agrivoltaic Research for Megawatt Scale (FARMS), and Photovoltaic Stormwater Management Research and Testing (PV-SMaRT) are funding innovations that improve the mutual benefits of solar development with wildlife and agriculture while mitigating the impact of solar systems on ecosystems.
