High-flying solar balloons could produce clean electricity night and

Combining solar photovoltaic PV panels, hydrogen production, and fuel cells, these solar balloons are meant to be deployed above the clouds.A team of researchers at NextPV, a lab jointly operated by the French National Center for Scientific Research and the University of Tokyo, are working toward building a prototype of a unique solar energy solution that could overcome some of the limitations of standard ground-based PV arrays.Solar has a lot of potential for being a major part of our renewable...

5 Solar Energy Trends for 2016 in the Residential Market

The U.S. has enough installed solar energy capacity to power 4.6 million homes. Solar energy accounted for 32 percent of total new power generation in 2014, exceeding coal and wind energy but lagging behind natural gas. In just nine years, the installed cost of solar energy has fallen by more than 73 percent setting up the industry for explosive growth.TriplePundit spoke with Vikram Aggarwal, founder and CEO of EnergySage, the so-called “Expedia of solar,” about solar energy trends ...

New efficiency record set with dual-junction solar cell

The newly certified record conversion efficiency of 29.8 percent was set using a top cell made of gallium indium phosphide developed by NREL, and a bottom cell made of crystalline silicon developed by CSEM using silicon heterojunction technology. The two cells were made separately and then stacked by NREL. The record was published in 'Solar cell efficiency tables.' "It's a record within this mechanically stacked category," said David Young, a senior researcher at NREL. "The performance of the du...

These Sky&High Balloons Could Generate More Power Than Solar

For all the cost and efficiency improvements in solar panels in the last few years, all land-based photovoltaics have one serious Achilles Heel: performance is dependent on the weather. If clouds are in the way, even the best solar panels don't work that well. That's why Jean-Franois Guillemoles wants to look above the clouds. A solar researcher from France, he's proposing floating solar balloons that potentially could generate three times as much power-per-foot as their terrestrial brethren. Hi...

Solar projects face some obstacles

Solar projects face some obstacles Along with many other business initiatives coming to the area, local residential and commercial solar energy projects are expected to continue gaining ground this year – although they may have to overcome a few obstacles along the way.

Solar energy set to boom with arrival of cheap battery technology

KIM LANDERS: In Western Australia rows of solar panels installed on suburban roofs are now producing as much electricity as the state's largest power turbine. It's part of a growing national trend that will see household solar energy meet a quarter of all Australia's electricity needs by 2020. As Anthony Stewart reports, experts are predicting this boom will be driven by the installation of super-sized batteries in the family home.ANTHONY STEWART: With 130 days of clear sunshine a year, the Wes...

Dave Roitman: Don't let solar energy production stall in Massachusetts

To the editor: Legislation to raise solar net metering caps is stalled in Massachusetts. Utility companies want to keep the caps. They argue that the growth of solar must be tightly controlled, so they can maintain infrastructure. If solar grows too fast, they say, it will overwhelm their ability to distribute energy. They also say that solar energy is a rip off for lower-income people. Under current net metering, solar homeowners pay less to their utility because the sun helps power their hom...

Ajmer airport to run on solar energy

JAIPUR: The Airport Authority of India will generate 100 megawatt power from solar energy to light up the under-construction Ajmer airport at Kishangarh. In this regard, the AAI's technical team recently earmarked an area to install the solar cell plates recently. "The solar electricity generated will be given to the Ajmer Vidyut Vitran Nigam Limited which in turn will provide it to the Ajmer airport," said BK Tailang, airport director, Jaipur, who is incharge of the Ajmer airport. The electri...

Annual solar power capacity to quadruple next fiscal year: Goyal

India may increase its solar energy capacity four-fold during the next fiscal year ending March 2017, Piyush Goel, Union Minister of Coal, Power and Renewable Energy says. “Today our solar capacity is about 4,500 MW and the capacity addition target for this year is about 2,000 MW. During 2016-17, we are hoping to add 12,000 MW in solar sector alone. Thus, including other renewable sources, there will be a total capacity addition of about 15,000 MW during next fiscal,” he said. T...

Solar: Yes or no?

Hello fellow real estate enthusiasts. So begins the hot question of the year: Kerry, would it be worth it to put solar panels on my house? Well, it depends. Sounds like a great idea, right? But I have to caution folks, especially military clients, who are only going to live in our area a short period of time. Transferees typically get assigned to Travis Air Force Base for three to four years. So the cost involved would not be worth it, in my opinion, because the return on investment wont really...
