Ascent Solar Technologies has bagged the Darpa Contract for its PhotoVoltaics Program. Darpa (Defense Advanced Research Projects Agency) has awarded the multi million dollar contract to Ascent Solar for its low cost, high efficiency portable photovoltaics program.
Mistaya Engineering and Second Wind have partnered to integrate the Windographer analysis software of Mistaya Engineering and the wind data collection technology of Second Wind into a solution for helping energy companies select and evaluate the most productive locations for installing their wind turbines.
Yingli Green Energy Holding Company Limited has announced that one of its subsidiaries Yingli Green Energy Americas, Inc. has inked a PV module supply contract with DC Power Systems till the close of 2010.
The wide bodied nacelle incorporated in the wind turbine comprises a central nacelle, two housings on the sides and a hub and allows easy access for maintenance. The electrical yaw and pitch control incorporated in this wind turbine maintains the rotor speed stably and cuts off the rotation during excessive winds.
The two sectional blade utilized in the wind turbine measuring a total of 62.50 m in length has an inboard section measuring 30.50 m and an outboard section measuring 32.00 m in length. The rotor of the wind turbine measures 128 m in diameter and offers a swept area of 12,868 m².
The Biodiesel is produced from a variety of first use vegetable oils and tested with all the conventionally designed diesel engines and proved to produce reduced level of contaminating emissions.
This wind turbine starts operating at 4 m/s wind speed, produces its optimal power of 3 MW at 12.5 m/s wind speed, and ceases its operations when the wind crosses the speed range of 20 to 25 m/s.
The multi function junction box utilized with the modules allows water proofed connectivity. The AS-6P27 photovoltaic modules effectively resist moisture and consequent etching problem.
The SCM 210 solar module incorporates multi contact Solarline 2 MC4 type of locking connectors for inter module connectivity and quicker system installation.
The solar cells comprised in this module are manufactured utilizing a patented SANYO technology of enveloping hybrids of single crystalline silicon cells with amorphous silicon layers.
