Solicitation Title: Request for Information for Photovoltaic Lifetime Project

Funding Number: DE-FOA-0001443


In return on investment calculations, the degradation and service lifetimes of PV modules are often assumed to be the same across different panels. Due to the typically slow pace of degradation in operating solar modules, often less than 1% (relative) per year, as well as variations in the operating and test conditions, the differences in panel degradation rates are difficult both to measure and compare. Much of the degradation data available to date involves precise measurement of the module performance at only one (end of life) or two (end of life and beginning of life) points in time. If the module’s degradation profile is not linear, a significant miscalculation of levelized cost of energy may result.

The purpose of this RFI is to solicit feedback from industry, academia, research laboratories, government agencies, and other stakeholders to identify approaches that would expand the dataset publicly available for service lifetime prediction for PV systems; specifically, data that would better inform calculations of the return on investment of existing and future PV installations.
