Researchers discover the hidden impact of solar panel shade
A group of environmental scientists and ecologists researching the impact of solar arrays on the environment have released a new study they believe will lead to smarter farming and land use around these alternative energy sources. According to the paper published in the journal Environmental Research Letters, the microclimate around the bank of photovoltaic panels studied near Swindon in the UK changed by as much as 5 degrees Celsius, depending on the season. While this might seem like an obvious side effect of creating a big field of artificial shade, the researchers from Lancaster University and the Centre for Ecology and Hydrology are concerned about the impact on the plants and soil underneath all those solar panels.
Apple to build a 20-megawatt solar farm for its Reno, Nevada data center
Apple's Reno, Nevada data center might be a lot greener in the next few years -- according to GigaOm, the company plans to build a 137 acre solar farm right next to it. The Nevada complex will reportedly generate between 18 and 20 megawatts of power similar to Apple's two arrays in North Carolina, but GigaOm says it will use a different kind of technology. Instead of a standard farm of solar panels, it will include mirrors that concentrate the sun's rays on each one up to seven times, increasing the amount of energy produced. In a statement sent to the publication, Cupertino revealed that the facility will not only provide electricity for the data center, but also supply energy to the local grid. Solar company SunPower will work on the array's engineering and construction, but until it's operational (which could be a while), Apple will depend on geothermal energy generated by local plants.

New construction at Apple's North Carolina data center poses for aerial photographs
Photos courtesy of Wired reveal that Apple's new "tactical" data center at its Maiden, North Carolina facility is well on its way to completion. Captured with the help of a decidedly low-tech airplane -- a 1949 Piper PA-11 Cub Special, if you must know -- the shots feature what appear to be the facade of the $1.9 million, 21,000 square-foot structure that was outed last month. The images also show glimpses of a second 20-megawatt photovoltaic array and what may be the foundations of the complex's planned 4.8-megawatt biofuel cell plant, which will convert biogas into electricity. With Apple's upcoming Reno project getting the rubber stamp of approval, it doesn't seem like the company will run out of construction projects any time soon.

Napa Valley winery flips on Flotovoltaic solar array
Chalk another one up for Sharp. The company has landed yet another partner willing to utilize its solar panels in order to make news, wow onlookers and give Mother Earth a modicum of a break. Napa Valley winery Far Niente has flipped on its self-coined Floatovoltaic installation, which was developed by Thompson Technology Industries and installed by SPG Solar. Nearly 2,300 Sharp solar panels were secured for the job, and we're told that the array generates 400 kWs at peak output, which "significantly offsets the winery's annual power usage and provides a net-zero energy bill." Don't expect that coveted bottle of Cabernet Sauvignon to be any cheaper as a result, though.[Via CNET]
Tear found on newly-unfurled space station solar array
It looks like the space station's latest solar array is causing NASA yet more headaches, as a small tear was spotted by astronauts shortly after it was unfurled earlier today. The first of two solar arrays installed as part of this mission did unfurl without a hitch, but the second forced the astronauts to abruptly stop the deployment and inspect the damage, with a final verdict apparently still yet to be determined. This follows the discovery of some metal shavings in a motorized joint on Sunday, for which NASA already added a day to Discovery's mission in order to conduct a detailed inspection. As the AP points out, the space station needs all the juice from the new array it can get, with both the European Space Agency's soon-to-be-launched Columbus science lab and an upcoming Japanese lab dependent on it for power.
