Solis Partners Completes Solar Installation For New Jersey Utility

FRANKLIN TOWNSHIP, N.J. (March 11, 2011) – Solis Partners, a leading developer and integrator of commercial solar power systems, and Public Service Electric and Gas Company (PSE&G), New Jersey’s oldest and largest publicly owned utility, recently celebrated the completion of a 921-kilowatt rooftop solar installation at the utility’s Central Division Headquarters in the Somerset section of Franklin Township, N.J.

The ribbon-cutting ceremony was attended by PSE&G executives, local elected officials and dignitaries, representatives from the solar panel supplier and the solar developer responsible for building the system.

Designed, engineered and deployed by Manasquan, N.J.-based Solis Partners, the system utilizes a combination of U.S.-made SolarWorld flat, glass-plated crystalline panels and Solyndra thin film panels.

The Somerset system is part of Newark-based PSE&G’s Solar 4 All™ program, a plan to invest $515 million on 80 megawatts of solar projects around the state between 2009 and 2013.

“With the hard work and commitment of key state legislators, the BPU and utilities such as PSE&G, New Jersey has become the sixth largest solar market in the world and a national leader in installed solar capacity — second only to California,” said Jamie Hahn, managing director of Solis Partners. “PSE&G’s Solar 4 All program has been key to that achievement. This project exemplifies PSE&G’s commitment to transforming underutilized commercial rooftops into clean renewable energy sources.”

Rooftop solar makes tremendous sense for New Jersey, which has more flat commercial rooftops per square mile than any other state, said Gary Weisman, director of sales for Solis, in remarks at the event.

“These underutilized rooftop assets are the perfect platform for deploying distributed solar generation facilities where power is most needed,” said Weisman. “Rooftop solar produces during the hours of peak demand, and provides power to the areas of the grid that need it the most — large commercial and industrial users.”

The innovative cylindrical panels from Solyndra are designed to optimize electricity production on commercial flat rooftops.  The ability of the system to cover more rooftop area and capture more light than traditional panels results in more annual solar electricity generation and will provide clean, low-cost power back to the utility grid for more than 25 years.

The Solyndra panels were integrated in the PSE&G system with a reflective white “cool” roof, which was on display at the ribbon cutting along with the Solyndra panels. The reflective roof not only enhances the efficiency of the building envelope from an energy savings perspective, but also increases the amount of solar production harvest.

Solis partnered with Allied Building Products Corp. on the project. Allied’s distribution team delivered the Solyndra and SolarWorld panels directly to the PSE&G rooftop and craned the Satcon inverters into place onto the concrete pad. Allied also provided the overall logistical support that allowed the project to be executed smoothly.

“For a project of this magnitude, staging and delivery are key to overall success and Allied has been a great partner in the role of solar distribution and logistics,” said Hahn.

At the ribbon cutting, the consensus of local dignitaries, which included New Jersey Assemblyman Upendra Chivukula and Somerset County Freeholder Patrick Scaglione, was that without a thriving renewable energy sector, the nation risks escalating dependence on fossil fuels, increased greenhouse gas emissions, reduced national security and the erosion of job creation within the clean energy sector.

In addition to being a great example of the advancements that are occurring in the solar sector, PSE&G’s Central Division Headquarters’ solar system illustrates how the Solar 4 All initiative is helping the renewable energy sector grow in New Jersey and the nation, said Al Matos, PSE&G’s vice president of Renewables and Energy Solutions, who delivered the opening remarks to the crowed of about 50 people.

“By installing large amounts of solar capacity in a reliable, orderly way, Solar 4 All is a driving force behind the renewable energy market,” said Matos. “Programs such as ours help create a predictable demand for these advanced products. This creates the kind of environment that solar companies need to spur innovation and cost efficiencies on their part, which then drives even more demand, more sales and more innovation.”

The benefits of having utilities such as PSE&G as major players in the renewable energy field extend beyond helping to create a market for solar companies, also helping ratepayers, he said.

“Our Solar 4 All program provides maximum benefit to PSE&G electric ratepayers,” said Matos. “Every one of the panels we are placing in service generates value from the sale of its electricity and capacity, the federal investment tax credits it realizes and the solar renewable energy certificates (SRECs) that it generates.”

Southern California Edison Awards 36 Contracts for Utility-Scale Solar Rooftop Project

Southern California Edison (SCE) awarded 36 contracts to independent power producers for a total of nearly 60 megawatts from photovoltaic solar panels that will produce emission-free energy for SCE customers. The panels will be installed on 31 unused rooftops and five ground-mount sites in SCE’s service territory.

The solar rooftop project, approved by the California Public Utilities Commission in June 2009, calls for a total of 500 megawatts of  solar generating capacity, most of it on otherwise unused large warehouse rooftops. Half of the 500 megawatts will be from independent power producers who respond to SCE’s request for offers under competitive solicitations; the remaining 250 megawatts will be owned and operated by SCE. It is expected that this project will create about 1,200 jobs for Southern Californians.

“These contracts make significant strides toward distributed renewable generation for one of the most innovative solar programs in the country,” said Marc Ulrich, SCE vice president, Renewable and Alternative Power. “We’re working to help California meet its Million Solar Roofs goal and supply even more renewable energy to our customers where and when it’s most needed, without the added time and expense to construct major new transmission facilities.” The contracts awarded today are the first executed under the competitive solicitations for independent power producers.

SCE believes that its solar rooftop project will be a boon for the solar industry and consumers alike, with the resulting cost per unit significantly more cost effective than more common residential photovoltaic installations in California. Eventually, this could help drive down installation costs of photovoltaic generation for everyone. When complete, the solar panels will cover an area totaling 4 square miles on about 250 otherwise unused warehouse roofs. The total power production will rival a utility-scale power plant, enough electricity to serve 325,000 average homes at a point in time. SCE has already installed panels on three rooftop warehouses in California’s Inland Empire that are delivering – or are in line to deliver – electricity to the grid.

SCE is the nation’s leading utility for renewable energy. In 2009, SCE delivered 13.6 billion kilowatt hours of renewable power to its customers, about 17 percent of its total power portfolio.

New solar energy product could revolutionize industry

From CoolerPlanet.com

A newly announced development from Dow Chemical may change the solar energy industry for homeowners in the coming years.

Dow’s new Powerhouse solar shingle is said to incorporate photovoltaic technology into a roof shingle, potentially allowing people to use their entire rooftop to generate electricity at a reasonable cost. According to the company, the new shingles will be on the market in limited quantities next year, becoming more widely available in 2011.

“These types of innovative products not only showcase our deep scientific and technical expertise but also demonstrate how our commitment to R&D is fueling Dow’s future growth agenda around the world,” said company chairman Andrew Liveris.

The news was also hailed by Michigan Governor Jennifer Granholm because of the green manufacturing jobs the new product is expected to bring to the state, which has it headquarters in the city of Midland.

The technology is said to involve thin film technologies that have been growing more common throughout the industry. In the coming years, thin film technology may provide advanced new applications for solar energy technology, such as wrapping or printing solar generating material onto a variety of surfaces.

Smart grid project features solar energy

From coolerplanet.com

A smart grid project getting underway in New York City will provide more information about how solar energy technology can be incorporated into existing power grids.

This week, Con Edison announced an 18-month smart grid pilot program that will take place in Queens. Residents will receive smart meters that will help them monitor home energy usage to better maximize efficiency and to help control costs.

However, the plan also features a 100-kilowatt solar roof array at a local community college that will be used to improve the integration of solar energy into the power grid of a densely populated area. The distributed solar energy project involves a partnership between Con Edison and the City University of New York.

“With this ‘smart grid’ agreement, CUNY is partnering with Con Edison to create a roadmap for New York and an example for the nation as we move toward energy independence. The University’s faculty and researchers will continue to work closely with Con Edison to identify new solar and renewable energy opportunities,” said university chancellor Matthew Goldstein.

While solar energy has been growing steadily in popularity, the electrical grid system is not always prepared to handle new sources of power. This is particularly the case for large utility-scale projects that tend to be located far from population centers.
