Digital Inkjet Printing: An Opportunity for Further Reductions in Solar Energy Costs

With solar on the cusp of economic feasibility in many areas, incremental cost reductions such as those offered by digital inkjet printing technologies can make the difference between moving ahead with solar and sticking with electricity from the local utility

Start of test with solar energy generating noise barriers alongside highway

Alongside the A2 highway near Den Bosch, The Netherlands, two test noise barriers are installed that generate solar energy. The aim of this practical test, that was officially launched 18 June is to assess the economic and technical feasibility of this form of energy generat

Vanadium Flow Batteries for Global Academy of Technology (GAT) College

By implementing the IMERGY storage solution in the premises, GAT is able to store the energy produced by the PV panels during the day and use it during the non-solar time, thus eliminating the diesel generator run to provide clean power when needed.

Is Adding Solar Batteries Worth it?

Seeking to help states better address the value proposition of solar+storage systems, the Interstate Renewable Energy Council, Inc. (IREC) engaged Clean Power Research (CPR) to develop a methodology that could be used to value solar energy coupled with battery storage. The m

New method can make cheaper solar energy storage

Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost.

The work is published in Nature Communications.

Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies but "2-D materials" have recently been identified as promising candidates. In general these materials—which famously include graphene—have extraordinary electronic properties. However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale and maintain good performance.

Kevin Sivula and colleagues at EPFL addressed this problem with an innovative and cheap method that uses the boundary between two non-mixing liquids. The researchers focused on one of the best 2-D materials for solar water splitting, called "tungsten diselenide". Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel while also being highly stable.  Cont'd...

PVinsights : Poly-silicon price is improved in China in July, but still weak outside China.

The average poly-silicon price has risen up owing to Chinese poly-silicon makers. Because of the expiration of the trade handbooks of their Chinese customers, a number of non-Chinese poly-silicon makers are seeing their sales to China being challenged by Chinese suppliers who now benefit from more price competitiveness. Chinese poly-silicon makers now have the leverage to pull up their selling price quotations within China, while non-Chinese suppliers have to adjust to the levy of import duties and AD & CVD charges on their products

OMG Roofing Products - PowerGrip Plus Roof Mount System

PowerGrip Plus Roof Mount System, a watertight structural attachment system used to secure ballasted solar racks and other equipment to roofs covered with thermoplastic (TPO and PVC) membranes. PowerGrip Plus is designed with wind performance in mind and offers ultimate tensile strength of 2,000 lbf. and ultimate shear strength of 1,075 lbf. Properly installed PowerGrip Plus units reduce rack movement and remaining watertight. PowerGrip Plus units are easy to install, saving both time and labor when compared to alternative options. A wide membrane skirt promotes easy welding in place, and the 15/8 diameter and 1/2 inch tall mount provides an optimal perch for securing brackets or struts. The exposed 1 inch tall and 3/8 inch diameter bolt and mounting stand are made from corrosion-resistant stainless steel and aluminum alloy for superior long-term performance.
