NREL Validation of S3.2 and S3.3 Cooperative Research and Development Final Report

Summary

This document is a final report for a Cooperative Research and Development Agreement (CRADA) between NREL and First Solar. The primary challenge was to validate First Solar's new PV module technology (S3.2 and S3.3), address performance shortfalls, and develop control algorithms for PV systems integrated with battery energy storage. NREL conducted extensive testing, including five-year outdoor monitoring, and collaborated on developing and testing control algorithms for a PV/battery system. The CRADA, which involved significant government in-kind funding, is now completed.
