SunEdison, Inc. (NYSE: SUNE), the largest global renewable energy development company, today announced the completion of three solar canopy systems for the City of Fremont, Calif. The systems are expected to generate 1.2 megawatts (MW) DC of clean, reliable electricity for the city.

The solar canopy systems are mounted on canopy structures over parking lots at the city’s Irvington Community Center, the Aqua Adventure Water Park, and the Robert Wasserman Fremont Police Center. The solar systems are expected to generate enough energy to power almost 150 homes each year and avoid the emission of more than 500 tons of carbon dioxide annually, equivalent to the amount of carbon sequestered by approximately 425 acres of forest.

The City of Fremont signed 20-year power purchase agreements with SunEdison as part of the Regional Renewable Energy Procurement Program (R-REP) led by Alameda County. It is projecting that the solar energy will save taxpayers more than $2.6 million dollars over the life of the agreement, and will result in a more than 5 percent reduction in city emissions following the completion of a fourth canopy system early next year.

Surging Growth Prompts Restart Solar to Open New Los Angeles County Showroom, Office & Warehouse

Restart Solar, a leading Southern California-based residential solar company with locations in Ventura County, San Bernadino County, and Orange County, announced today that in response to surging demand for its cost and energy-saving solar system installations, it has opened a new 5518 square foot showroom, office and warehouse in Los Angeles County at 1501 Truman Street, Los Angeles 91340.

“Since day one, our business model has always been to be the best local residential solar company in every area that we serve,” commented DeMarinis. “Now through our new location, we can get to our Los Angeles County customers much faster. We can also invite them to come in and meet our amazing team, see our advanced products and equipment, and enjoy a better overall customer experience. Simply having happy customers isn’t good enough. We strive to make our customers raving fans, and our new location is a key part of this ongoing commitment.”

GE Power Conversion Breathes Life into the Japanese Solar Market with Highly Reliable and Cost-Effective Solutions

GE Power Station
  • GE Power Conversion is supporting the Hosoe mega solar project in Japan with its Brilliance inverter skid solutions, offering a complete equipment and 20-year lifecycle services package tailor-made for the Japanese solar market
  • GE’s technology offers reliability and smooth integration into the solar farm and grid, while being cost-effective and fully compliant with local standards
  • The solar farm is planned to commence commercial operations in 2018 and will be one of the biggest in Japan

Miyazaki, Japan – 30 July – Your average solar farm won’t get very far if the task at hand is to change the way in which energy is generated for 50 million Japanese households – here, you have to think big. That’s why the Hosoe solar project in Japan, planned to be in service by 2018 and equipped with GE Power Conversion technology, will be anything but average.

Located on Kyushu Island, the 96.2-megawatt (DC) photovoltaic solar plant is set to be one of the largest in Japan, and is expected to generate clean energy for up to 30,000 households, delivering annual CO2 emission savings of 68,200 tons. To enable this operation with enhanced efficiency, the developer of the project, Pacifico Energy K.K., selected GE Power Conversion to supply its Brilliance inverters for the mega solar project.

The New Story of Solar Energy

The second birth of solar energy started in 2009, and has grown from a technological curiosity to one of the fastest growing energy markets worldwide, with the potential for profound social and ecological impacts. However, solar energy constitutes only around 1% of the global energy mix. How did we get here, and what are the innovations needed to realize the true potential of solar energy in the future?

Rob Andrews is the CEO and co-founder of Heliolytics, a technology company developing advanced optical inspection techniques for large solar energy facilities utilizing robotic technology. He was previously the director of Calama Consulting, a solar energy performance consulting firm, and has worked with solar energy clients globally to develop system monitoring and maintenance plans, optimize plant performance, and integrate new technologies.

Martifer Solar Connects Self-Consumption Solar PV Rooftop Plant in El Salvador

Martifer-EL Salvador

Martifer Solar, a subsidiary of Martifer SGPS, has completed a new self-consumption solar PV plant located on a commercial rooftop in the Santa Tecla, El Salvador. The plant, with a total installed capacity of 300 kW, was developed by Martifer Solar’s local partner, DESENI, and was built for one of El Salvador’s largest distribution companies of consumer products, DISZASA.

Martifer Solar was responsible for the engineering, procurement and construction (EPC) services for the PV rooftop plant. The 300 kW plant, with approximately 1,000 solar panels, will produce clean energy and will lead to the reduction of the commercial facility’s energy bill by up to 18% on an annual basis. With an area of 2000 m2, the PV plant will produce an estimated 486 MWh/year. With this production capacity, the plant will offset 350 tons of carbon dioxide emissions annually and will provide sufficient energy to power more than 1500 inhabitants per year.

“The Salvadoran photovoltaic market is evolving and solar energy will be highly important in the energy mix of the country. Thanks to high levels of solar radiation and the number of hours of sunshine, El Salvador offers ideal conditions for generating energy from solar photovoltaic systems. There is great potential for the development of solar installations on rooftop, especially in commercial and industrial buildings,” said Ismael García, Head of Business Development for Central America and the Caribbean for Martifer Solar.

One Step Closer to Artificial Photosynthesis and “Solar Fuels”

Caltech scientists, inspired by a chemical process found in leaves, have developed an electrically conductive film that could help pave the way for devices capable of harnessing sunlight to split water into hydrogen fuel.

When applied to semiconducting materials such as silicon, the nickel oxide film prevents rust buildup and facilitates an important chemical process in the solar-driven production of fuels such as methane or hydrogen.

“We have developed a new type of protective coating that enables a key process in the solar-driven production of fuels to be performed with record efficiency, stability, and effectiveness, and in a system that is intrinsically safe and does not produce explosive mixtures of hydrogen and oxygen,” says Nate Lewis, the George L. Argyros Professor and professor of chemistry at Caltech and a coauthor of a new study, published the week of March 9 in the online issue of the journal the Proceedings of the National Academy of Sciences, that describes the film.

The development could help lead to safe, efficient artificial photosynthetic systems—also called solar-fuel generators or “artificial leaves”—that replicate the natural process of photosynthesis that plants use to convert sunlight, water, and carbon dioxide into oxygen and fuel in the form of carbohydrates, or sugars.

Power Shift: From Fossil Energy to Dynamic Solar Power

Power Shift Book Cover


Solar Energy is the Future and the Time Has Come

The world is going solar everywhere you look. Google is investing $300 million in SolarCity. Apple is building a massive $850 million solar farm in California. Utilities and small businesses are placing solar panels on rooftops, homeowners are finding out that they can save money on home installations, and even Pakistani farmers are finding out there are benefits in switching from diesel to solar.

The world is transitioning from fossil fuels to solar power, and it’s a change that is setting humanity on a new course for the future.

The newly released book Power Shift: From Fossil Energy to Dynamic Solar Power, by Robert A. Stayton, explores this fundamental change in the human relationship with energy.

“Solar energy is the clear economic and environmental choice,” says Stayton. “The advantages over oil, gas, coal, nuclear, wind, and hydro make it the best choice hands down. Its time has come.”

“We are at the beginning of a new epoch in history,” Stayton says. “If you live a modern energy-enabled lifestyle, then you’re a player in this drama, and you have choices to make. The energy decisions you make today will decide the fate of many generations to come.”
