On July 20, SunEdison, the world's biggest renewable energy development firm, along with TerraForm Power, an owner and operator of clean energy power plants, announced the acquisition of Vivint Solar, a major supplier of residential solar systems in the U.S.
The merger will be worth approximately $2.2 billion in cash as the two major solar companies acquire the residential solar firm. Additionally, SunEdison has agreed to enter a power purchase agreement with TerraForm Power. Roughly 523 megawatts of solar power will be installed by Vivint Solar by the end of 2015, which will now all be moved over to SunEdison.
Through the $922 million power agreement, TerraForm Power will install the solar panels for residential solar protections through a "10-year average levered cash-on-cash yield of 9.5 percent," the release stated. Also, TerraForm Power will obtain future small commercial solar and completed residential projects from SunEdison's Residential and Small Commercial business unit. Cont'd...
Parker Hannifin Power Conversion System Selected By Primus Power to Support Energypod® Enabling Microgrid at US Marine Corps Base
A team of researchers has come up with a solar cell that produces fuel rather than electricity. A material called gallium phosphide enables the solar cell to produce clean fuel hydrogen gas from liquid water.
To connect an existing silicon solar cell to a battery that splits the water may well be an efficient solution; but it is very expensive.
So, researchers were streamlining their search to a semi-conductor material that is able to both convert sunlight into an electrical charge and split water.
The team found gallium phosphide (GaP), a compound of gallium and phosphide, useful in this respect.
GaP has good electrical properties but the drawback is that it cannot easily absorb light when it is a large flat surface as used in GaP solar cells, said the study thatappeared in Nature Communications.
The researchers overcame this by making a grid of very small GaP nanowires, measuring five hundred nanometres (a millionth of a millimetre) long and ninety nanometres thick.
"That makes these kinds of cells potentially a great deal cheaper," said lead author Erik Bakkers from Eindhoven University of Technology, the Netherlands. Cont'd...
