Battling corrosion to keep solar panels humming
Sue Holmes for Phys.org: People think of corrosion as rust on cars or oxidation that blackens silver, but it also harms critical electronics and connections in solar panels, lowering the amount of electricity produced.
"It's challenging to predict and even more challenging to design ways to reduce it because it's highly dependent on material and environmental conditions," said Eric Schindelholz, a Sandia National Laboratories materials reliability researcher who studies corrosion and how it affects photovoltaic (PV) system performance.
Sandia researchers from different departments collaborate to accelerate corrosion under controlled conditions and use what they learn to help industry develop longer-lasting PV panels and increase reliability. For example, work by Olga Lavrova of Sandia's Photovoltaic and Distributed Systems Integration department demonstrated, for the first time, a link between corrosion and the risk of arc faults in PV systems' electrical connections. Research by Erik Spoerke of Sandia's Electronic, Optical and Nano Materials department focuses on developing new nanocomposite films that could dramatically increase reliability. Cont'd...

Saudi Arabia Plans the World's Cheapest Power With Solar and Wind
Wael Mahdi for Bloomberg: Saudi Arabia will award its first tender to build 700 megawatts of solar and wind energy in September, with the cost of power forecast to be the lowest in the world, Energy Minister Khalid Al-Falih said.
OPEC’s biggest oil producer plans to build 300 megawatts of solar plants in the al-Jouf area in northern Saudi Arabia and 400 megawatts of wind projects in nearby Tabuk, he said. Requests to qualify for bidding will be issued Feb. 20 and bids will be on April 17.
“The terms on renewable contracts will be motivating so that the cost of generating power from these renewable sources will be the lowest in the world,” Al-Falih said Wednesday at a press conference in Riyadh. Cont'd...

Massive wind turbine takes energy generation record
John Anderson for NewAtlas: A behemoth V164 offshore wind turbine from Danish company MHI Vestas Offshore Wind has produced almost 216,000 kWh over a 24-hour period during tests at its site near Østerild, Denmark in December. In doing so, the 9 MW prototype – a reworked version of the V164-8.0 MW, which was initially developed in 2012 and launched two years later – takes the energy generation record for a commercially available offshore wind turbine.
Since its launch in 2014, the Usain Bolt of wind turbines is essentially in competition with itself, largely due to its superior size over the competition. The V164 stands at 722 feet (220 m) at full height, with 38-ton blades that are 263 feet (80 m) in length for a total sweep area of 227,377 square feet (21,124 square meters) – larger than the giant London Eye Ferris wheel.
