NREL argues for value of ‘watts per kilogram’ in emerging thin-film, flexible solar technology

November 15, 2018 at 10:06 am 0 comments

Rigid silicon solar panels dominate the utility and residential markets, but opportunity exists for thin-film photovoltaic and emerging technologies notable for being lightweight and flexible, according to scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). Thin films such as cadmium telluride (CdTe) and copper indium galliumRead More

Shave and a rate cut: How solar + storage solutions are shaving peaks, saving big bucks

Shave and a rate cut: How solar + storage solutions are shaving peaks, saving big bucks

Shaving the peaks off commercial and industrial (C&I) electric bills is the top revenue stream for energy storage systems, and given the trend in increasing utility charges for time-of-use consumption, peak shaving can pay for a system in as little as three years, system providers say. Just how high theRead More

As perovskite solar cells set efficiency records and the nascent technology becomes more stable, another major challenge remains: the issue of scalability, according to researchers at the Department of Energy’s National Renewable Energy Laboratory (NREL). “It is scalable,” said Kai Zhu, a materials science researcher at NREL. “We just needRead More

RdTools results show time-series data along with a year-on-year degradation distribution. The same system is analyzed with the clear-sky method (a), and sensor-based method with a poorly maintained sensor (b). In this case, high reported degradation is likely caused by sensor drift, rather than a degrading PV module

NREL promotes new solar tool to accurately calculate PV module degradation rates

How long a product can be expected to perform at a high level is a fundamental indication of quality and durability. In the solar industry, accurately predicting the longevity of photovoltaic (PV) panels is essential to increase energy production, lower costs, and raise investor and consumer confidence. A new softwareRead More
