The Solar Newsletter is an electronic newsletter that provides information on NREL's research and development of solar technologies.
The multiyear North American Renewable Integration Study (NARIS) explores continentwide integration of renewable energy to support a low-carbon future grid. Results show increasing electricity trade and expanding transmission could have significant benefits.
Repair, repower, reuse, or recycle? Three new NREL reports consider options for responsible, cost-effective decommissioning of retired PV equipment.
Cadmium telluride, CIGS, perovskite, and other thin-film PV technologies could all benefit from a passivation technique recently demonstrated by NREL researchers. See how cross-technology collaboration at NREL unlocked this advance.
Recent NREL work reveals two key findings that collectively constitute a “curtailment paradox” that emerges as grids evolve to higher solar penetration levels. The findings highlight the importance of thermal generator flexibility and solar operating reserves.
NREL analysts developed the Distributed Generation Market Demand (dGen) model to simulate how customers make decisions about rooftop solar. This explainer video outlines the factors that impact customer decisions and how the dGen model considers them.

Staff Profile – Ingrid Repins
Principal Scientist and Research Fellow
PV Reliability Group
Ingrid Repins brings a long history in PV research and a deep knowledge of device physics to the study of PV degradation. Her team aims to better understand why PV modules degrade, reproduce degradation in the lab, and quantify its effects. She also teaches the occasional yoga class at NREL.
"I used to think that solar energy was all about maximizing electrons. But it also really matters how long systems last. Anything that affects the energy yield over the lifetime of the module is of interest to us."
