The Solar Energy Technologies Office (SETO) Lab Call FY2019-21 funding program will enable U.S. national laboratories to provide accurate information and analysis related to solar energy on the grid, helping the industry overcome information barriers that inhibit solar energy access, affordability, and reliability. Overcoming these barriers will help decrease the cost and risk associated with research on new technologies and improve customer choice and transparency, all of which can lead to lower solar electricity costs.

Researchers at the national labs will also explore concentrating solar-thermal power, photovoltaic, and grid integration research as part of this effort. Learn more about the SETO Lab Call FY2019-21 projects.

Project Name: Interoperable Energy Information Database for Real Estate          
Lab: Lawrence Berkeley National Laboratory      
Location: Berkeley, CA 
Principal Investigator: Ben Hoen
Project Summary Solar is growing rapidly, but data about the accurate valuation of homes with photovoltaic (PV) solar is lacking, as is information-sharing between solar data sources and real estate multiple listing services (MLS). Building on the project team’s past work, this project will combine previous ad hoc efforts to auto-populate PV data in an MLS database. This database holds energy-efficiency data and software infrastructure from the Home Energy Labeling Information eXchange (HELIX) repository, and this project would result in a solar-data-enhanced version of the HELIX package. Guided by an industry advisory team, the team will partner with the HELIX project leader and software developers to enable HELIX to accept solar data and disseminate information about it.              

Project Name: Solar-to-Grid (S2G): Analytic Support to Inform Reliability, Market Value, and Affordability           
Lab: Lawrence Berkeley National Laboratory      
Location: Berkeley, CA 
Principal Investigator: Andrew Mills
Project Summary: Along with the cost of a photovoltaic solar system, the competitiveness of solar energy depends on its market value and how solar interacts with other technologies in electricity markets. This project aims to better understand the location-specific market value of solar, the contribution of solar to grid reliability, and the impact of solar on the power system. The project team will combine historical production and performance data from solar energy systems across the United States with electricity market data to identify trends in solar’s historical value and contribution to grid reliability. To assess the impact of solar on the power system, the team will rely on market data to observe trends in wholesale prices and the resulting incentives to invest in flexible resources, like combined-cycle gas turbines and storage. The geographically specific results will be communicated through three annual reports, each building on and updating data from the previous year, to help inform stakeholders on planning, procurement, market design, and grid operations.

Project Name: Resilient Planning for Distributed PV        
Lab: National Renewable Energy Laboratory
Location: Golden, CO    
Principal Investigator: Benjamin Sigrin
Project Summary: The Resilient Planning for Distributed Energy Resources (RiDER) project seeks to help grid planners better predict where distributed energy resources (DER) like rooftop solar and battery storage will be installed.

Project Name: Valuation and Operational Performance of Solar-Plus-Storage Power Plants         
Lab: National Renewable Energy Laboratory       
Location: Golden, CO    
Principal Investigator: Paul Denholm
Project Summary: As energy storage costs decrease, new opportunities arise to create solar power plants with dispatchable energy, making power available whenever it’s needed from both concentrating solar-thermal power (CSP) and photovoltaic (PV) technologies. But understanding the various plant configurations and storage-operation modes can be challenging. For example, PV and battery developers must consider the relative sizes of module, inverter, and storage power and energy capacities, as well as where in the system to integrate energy storage. This project will develop improved methods for evaluating and comparing different solar-plus-storage technologies and configurations to help utilities and system planners develop low-cost, reliable power systems.
