Unique Uses for Solar Power

Small hydropower company Eagle Creek has completed the purchase of around ten hydroelectric power generation facilities from Algonquin Power. The facilities are located in the Northeast of the United States and have a total generating capacity of around 29 megawatts, enough to produce around 100 million kilowatt hours of renewable energy a year. Under the management of a team from...

Cost of solar cells could be reduced by 73-percent

As the demand for solar power increases, innovation and development increases as well. In order to make profits, solar organizations and companies need to invest in more cost efficient methods to harness the power of the sun. In previous cases, solar arrays were built using cheaper materials that decreased the quality of such arrays. However, a new discovery could begin to decrease the cost of panels while...

White House to sport solar panels, get its power from sunny days

Three years after it was first announced, the White House is finally getting its new solar panels. According to the Washington Post, a White House official confirmed on Thursday that the White House began installing solar panels this week. The administration of President Barak Obama had originally pledged in October 2010 to put solar panels on the White House as a sign of the president’s commitment to renewable energy. At that...

Solar Energy With a Side of Wind

Throughout the U.S., the sun shines the brightest and longest during the summer months, when the wind speeds are lowest. During the winter, the winds are more intense and sunlight is less available. Because peak operating times are different for these methods of alternative energy, combining the two systems helps generate a steady source of power while increasing your energy independence. A hybrid...

Lighter, Thinner Solar Panels Could Power Endless TV on Smartphones

Despite the evolution of mobile smartphone technology, one factor seems to hold us back: dead or dying batteries. New advances in solar technology could signal an end to the short, red battery indicator and the “chirping” sound we hear when our cell phone batteries are minutes away from flat-lining. Massachusetts Institute of Technology (MIT) researchers have announced an effort to produce the thinnest and lightest solar...

Common Misconceptions About Going Solar

It's true that your solar photovoltaic solar panels will generate the most energy when the sun is highest in the sky (during the day). But for grid-connected systems, the energy harnessed will be fed back to the grid and cause your meter to spin backwards. This results in credit from the utility company for future energy use. “I like to call refer to this as the virtual battery,” said Kevin Moore, ...

First full-solar powered plane successfully flies across U.S.

Solar Impulse, the first ever full-solar powered airplane, has successfully flown across the United States of America, setting a new milestone in the history of aviation. The solar-powered airplane began its journey back in May 3 in San Francisco, California, and landed on its final destination at New York’s John F. Kennedy International Airport July 6, at 11:09 p.m. E.D.T. Its arrival in New York was three...

Punjab’s state nodal agency awards Welspun Energy 32 MW solar-project

India’s Punjab Energy Development Agency, a nodal agency that develops renewable energy projects, has awarded Welspun Energy Ltd. a 32 megawatt-solar project through a single state competitive bidding. The project, which is expected to be commissioned during the second quarter of 2014, is split into two – one 30 MW and the other 2 MW. The project can feed up to 56 million units of renewable energy into the...

N.R.E.L. reaches world record with 31.1 percent solar conversion efficiency

A world record of 31.1 percent conversion efficiency for a two-junction solar cell was reached by the United States Department of Energy’s National Renewable Energy Lab. The two-junction solar cell, with an area of about 0.25 square centimeters and an AM1.5 global spectrum measured at 1,000 W/m2, is made of a gallium indium phosphide cell on top of a gallium arsenide cell. The front of the cell is covered...

Alion Energy uses robots to lower cost of solar installation and cleaning

Alion Energy, a California-based company that provides solar installation and maintenance services, uses a pair of robots to improve the speed of construction and the costs of utility scale solar projects. The company uses two robots; ROVER, an automated installation vehicle; and SPOT, a robotic cleaning solution. Together, the robots are able to build and maintain utility scale plants twice as fast and require...
