Bankable Data and Interoperability Standards

Data quality derives from the combination of accurate instruments plus Data Encoding Standards: one can take highly accurate data samples but if there is no agreement as to what the data means, the data could be considered to be of low quality because of its inability to improve the decision making process.

A Modular Hydrogen Facility at a University Campus

This facility is based around a modular platform, which provides maximum flexibility for the customer. It contains a hydrogen production component (electrolysers) and a hydrogen storage component (compressed gas cylinders).

The Trouble With DIY Solar

There is much to consider before pulling the trigger on a DIY solar kit and attempting a solar panel installation for your home (even if there is a YouTube video that shows you how easy it is to build your own solar panels).

Recent Cost Reductions Driven By Racking Innovation

Several new mounting systems have been developed that utilize polymers to enable cost reductions. Polymers are also roof friendly and non-corrosive, making this material a more attractive alternative to metal on flat roofs.

Aluminum Continues KnowledgeSurge in Cost-driven Solar

Light weight, strength and corrosion resistance represent three of the benefits. "Aluminum profiles can be made as structurally strong as needed for most applications,"

GE / Xtreme Power Partnership

GE's product technology provides the capability of producing vast quantities of energy and XP's controls and system integration technology provides the capability to connect to the electricity grid and manage the movement and storage of electricity.

Q&A with Rhone Resch, President and CEO of the Solar Energy Industries Association

The value of solar PV completed in 2011 alone in the U.S. is $8.4 billion. Globally, the value was $93 billion. 100,000 people are employed by 5,600 solar companies throughout the U.S. - across all 50 states.

Solar Power and the Utilities - SEPA at SPI 2012

There is a wide range of utility experiences, but about 70% of solar activity is concentrated in the top 10 utilities as measured by our annual survey ( The top 50 utilities encompass greater than 95% of the solar.

RED, WHITE & GREEN: The True Colors of America's Clean Tech Jobs

Seven of the top 17 states with the most rapid growth in the clean tech sector are considered swing states for the 2012 presidential election. Numbers like these suggest we are entering an era in which politicians who unfairly criticize or otherwise ignore clean tech run the risk of alienating a bedrock constituency: job holders, most of whom vote. We all need to understand that green jobs and clean tech are not merely the idle dreaming of a small group of partisan activists and insiders, but a source of livelihood for millions of Americans, literally in all parts of the country. What's more, their numbers are growing every day.

Peak What?

Peak oil? coal? gas? tar sands? shale gas? or any such? New discoveries seem to outpace all fears of early shortages. CO2 and AGW worries groundless? The jury is still out on that. Does that mean we can live free of any worries and carry on without any further need for doomsayers and troglodytes? Well yes, based on such questions. But could it just be possible that these are not the right questions to ask as they might produce wrong answers and consequently lead to wrong policies and investments?

The National Solar Tour, Oct 6

The ASES National Solar Tour is the world's largest grassroots solar event. More than 160,000 participants will visit some 5,500 buildings in 3,200 communities across the U.S.

Battery Performance of Microfiber/Nanofiber Lithium Ion Battery Separators

Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow due to low porosity and high "dead space" that come from starting with a solid material and trying to impart porosity. This work uses an alternative approach, where linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60-70%) and so have much higher ionic flow.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
