Gone with the wind: Surprising potential to improve reliability in wind power

Science Daily:  Despite the rigors of scientific inquiry and the methodical approaches of the world's most talented researchers, sometimes science has a surprise in store.

Such was the case when a group of researchers from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Akron discovered that a particular form of carbon coating not necessarily designed for wind turbines may indeed prove a boon to the wind industry -- a serendipitous finding that was recently highlighted in the journal Tribology International.

Due to the strenuous environment inherent in wind turbine drivetrains, key components such as actuators, bearings and gears are prone to failure, meaning turbines require regular maintenance that helps drive up the price of wind energy. Prolonging the life of these components could greatly reduce the cost of wind power, the fastest growing source of energy in the world, thereby making it an even more attractive energy source.  Cont'd...

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.
