Why Your Business Should Consider Solar Power
March 25, 2013

During the process of running a business, entrepreneurs are always looking for ways to reduce costs and become more profitable. One option that many businesses are now considering is investing in solar power. If you’re thinking about solar for your company, is it worth the investment?

Prices Have Fallen

Government Incentives

Accelerated Depreciation

Indian State Of Punjab Launches 300MW Solar Power Tender
March 25, 2013

The north Indian state of Punjab has issued a fresh tender for installation of 300 MW of solar power capacity.

The state joins list of several others like Tamil Nadu, Karnataka, and Andhra Pradesh to issue huge tenders for setting up solar power capacity.

Punjab lies in the west north-west belt of India which receives significantly high solar radiation making the region suitable for large-scale solar power infrastructure development.

Other states laying in the region, Gujarat and Rajasthan, boast over 90% of India’s installed solar capacity. Both the states have been pioneers in development of solar power sector in India.

Nanowire solar cells raises efficiency limit

Scientists from the Nano-Science Center at the Niels Bohr Institut, Denmark and the Ecole Polytechnique Fédérale de Lausanne, Switzerland, have shown that a single nanowire can concentrate the sunlight up to 15 times of the normal sun light intensity. The results are surprising and the potential for developing a new type of highly efficient solar cells is great.


- Due to some unique physical light absorption properties of nanowires, the limit of how much energy we can utilize from the sun's rays is higher than previous believed. These results demonstrate the great potential of development of nanowire-based solar cells, says PhD Peter Krogstrup on the surprising discovery that is described in the journal Nature Photonics.

The research groups have during recent years studied how to develop and improve the quality of the nanowire crystals, which is a cylindrical structure with a diameter of about 10,000 part of a human hair. The nanowires are predicted to have great potential in the development not only of solar cells, but also of future quantum computers and other electronic products.

- It turns out that the nanowires naturally concentrate the sun's rays into a very small area in the crystal by up to a factor 15. Because the diameter of a nanowire crystal is smaller than the wavelength of the light coming from the sun it can cause resonances in the intensity of light in and around nanowires. Thus, the resonances can give a concentrated sunlight, where the energy is converted, which can be used to give a higher conversion effeciency of the sun's energy, says Peter Krogstrup, who with this discovery contributes to that the research in solar cell technology based on nanowires get a real boost.

Gila Bend Solar Project Offsets Energy Usage By 86%
March 25, 2013 Kathleen Zipp : 0 Comments

SOLON Corporation, providers of turnkey solar power plants, has completed construction of a 459-kW solar PV system at the Reverse Osmosis Water Treatment Facility for the Town of Gila Bend, Arizona.

The system is expected to offset the energy usage of the water treatment facility by 86 percent, which will save money for the Town of Gila Bend through reduced utility bills.

“The incorporation of solar into this water treatment facility is another great example of solar’s versatility at reducing power costs across the electric demand spectrum,” said Jared Schoch, Vice President and General Manager of Power Plants at SOLON Corporation. “We are very excited to complete this PV project for the community of Gila Bend.”

SOLON engineered, designed, constructed, and commissioned the fixed-tilt system. As a full service system provider, SOLON will continue to operate and maintain the system on behalf of Gila Bend.
