Renewable Energy Resources

Lithium-Ion Batteries

Our Lithium-ion Batteries journal covers three key subjects that further demonstrate how UL is working to enhance the safety of this sustainable energy source...please download our report for more information!

New Science - Innovating Safety Standards for Energy-Efficient Lighting - Progressing Grid Interconnection Standards - Mitigating Emerging EV Battery Risks - Thermal Modeling of LED Lights

Rising costs, energy efficiency and environmental impact demand innovations in energy generation, distribution, management and usage. Our Sustainable Energy journal covers four subjects that demonstrate important ways UL’s team of dedicated scientists, engineers and researchers are developing New Science to make energy cleaner, more reliable, more efficient and...

Enphase Microinverters and Ungrounded PV Arrays

Enphase has developed a new microinverter family that includes the M250 and new M215 with integrated (DC isolated) ground. Because the DC circuit is isolated and insulated from ground, these microinverters do not require a Grounding Electrode Conductor (GEC) connected between each microinverter. The Enphase Microinverters with Integrated Ground are compatible...

UltraBattery® - Benefits of a Breakthrough Storage Technology

Energy storage, installed within grids and mircrogrids, can enhance grid stability and fossil fuel efficiency. Storage also makes it possible to install a higher proportion of renewable energy into the grid, since the inherent fluctuations of such sources can be smoothed out: peaks can be stored and troughs can be filled. To perform these functions, the technology...

New Science - Measuring Offshore Wind Power - Advancing the Smart Grid - The Safety of Smart Appliances

Measuring Offshore Wind Power Through measurement sensor technology and the most extensive data to date, we are collaborating with public and private stakeholders in Germany to accelerate the advancement of offshore wind power. Advancing the Smart Grid UL is participating in a pioneering smart grid research project, Pecan Street Demonstration, compiling the industry’s...

New Science - Sustainable Energy: Lithium-Ion Batteries

Progress is an unstoppable, transformative force. New technologies, product advances and globalization are arriving one on top of another at a dizzying pace. Innovation makes us more efficient, more productive and more connected. But there is a cost, and that cost is risk. To help mitigate the emerging risks, UL is developing New Science. Through fundamental...

NABCEP PV Installation Professional Resource Guide

The NABCEP PV Installation Professional Resource Guide was developed to provide an overview of some of the basic requirements for solar photovoltaic (PV) system installations and those who install them. Readers should use this document along with the 2011 National Electrical Code® (NEC®), the governing building codes and other applicable standards. These codes...

New Challenges Call For New Science

How Energy Storage Will Help Cleantech See More “Green”

Cost-effective storage is the single most important factor in deciding the wide-scale adoption of renewable energy. New advancements in storage technologies are ushering in an era of rebirth and unlimited possibilities in renewable energy. So ask yourself this: when opportunity in cleantech knocks, will your business be ready to scale when and where the market...

Achieving Better Module Performance at the Wafer Level

As PV module manufacturers battle it out for market share in what is perhaps the most competitive industry in the world, those manufacturers are constantly looking for ways to improve module efficiencies and performance, while keeping control of their costs. Most module manufacturers make these enhancements at the cell level. ReneSola, however, is controlling...
