IBM Unveils Wind And
Solar Forecasting System
IBM has developed a power and weather modeling technology to help utilities integrate renewable energy resources into the grid more reliably. The new system combines weather prediction and analytics to forecast the availability of wind power and solar energy.
The Hybrid Renewable Energy Forecasting (HyRef) system uses weather modeling capabilities, cloud imaging technology and sky-facing cameras to track cloud movements.
IBM says this level of insight will enable utilities to better manage the variable nature of wind and solar and more accurately forecast the amount of power that can be redirected into the power grid or stored. It will also allow energy organizations to easily integrate other conventional sources such as coal and natural gas.
According to IBM, China’s State Grid Jibei Electricity Power Co. Ltd. (SG-JBEPC), a subsidiary company of the State Grid Corporation of China, is using HyRef to integrate renewable energy into the grid. This initiative, led by SG-JBEPC, is phase one of the Zhangbei 670 MW demonstration project, a renewable energy initiative that combines wind and solar power, energy storage, and transmission. This project is part of China’s five-year plan to reduce its reliance on fossil fuels.

Naval Lab Develops
Field Solar Sensor
Research scientists at the U.S. Naval Research Laboratory’s (NRL) Electronics Science and Technology Division have developed a low-cost spectral sensor for field analysis of solar cell irradiance performance and spectral distribution.
Spectral radiometers are widely used to measure the spectrum of emitted, transmitted or reflected light of a given material. According to the NRL, current spectral radiometers generally require sophisticated optical components for beam forming and diffraction, refined electronic components for the signal readout, or moving parts that contribute to inefficient power consumption and high production costs.
The new sensor system can be used in remote solar radiation monitoring applications such as mobile solar power units as well as in long-term environmental monitoring systems where high precision and low power consumption are necessities. Mobile solar power units have been recognized as a promising route toward decreasing the dependence of the military on fossil fuel generated power.

TS-Space Systems Launches
Compact Solar Simulator
U.K.-based TS-Space Systems is offering its Unisim Compact solar simulator as a bench top unit complete with a current versus voltage (IV) measurement system.
The enclosure houses a TS-Space Systems’ 2-zone Unisim solar simulator that combines metal halide and incandescent sources via a proprietary filter system to give an air mass zero close-match spectrum.
The standard system includes an embedded source meter with a complete IV measurement system (computer, GPIB interface, IV software, MS Excel), relative irradiance indicator for monitoring lamp intensity and a manual shutter.

SK Group Invests
$19M In HelioVolt
South Korea-based SK Group has made a $19 million investment in U.S.-based solar technology developer HelioVolt Corp. to commercialize its copper, indium, gallium, selenium (CIGS) modules.
HelioVolt says that after several years of limited product shipments from its current facility in Austin, Texas, it is preparing to expand its capacity. The company wants to target residential, commercial and utility-scale projects with its thin-film CIGS modules.
HelioVolt is collaborating with Austin Energy on a commercial install of its modules on the roof of the nonprofit Yellow Bike Project. Austin Energy will own the 12.4 kW solar power system.

Schneider Releases
New Inverter/Charger
Schneider Electric has released its latest off-grid solar and backup power inverter/charger, the Conext SW.
Schneider says the Conext SW provides pure sine wave output inverter/chargers in power ranges of 4 kW and lower, enabling it to effectively run modern electrical appliances and equipment.
Intended for off-grid solar, backup power and small community electrification applications, the Conext SW is a 24 V system that offers selectable 50/60 Hz functionality. It is available in 120/240 VAC or 230 VAC models, and in 2.5 kW or 4.0 kW versions. Breaker panels and accessories are available to build a complete system that communicates through simple network architecture.
Schneider Electric’s line of Conext solar products now also includes the new Conext ComBox, a communication gateway for setting up and monitoring off-grid installations. The device enables operators of Conext solar systems to remotely monitor yield performance using personal computers, tablet devices or building management systems.
