Balikatan 2011 Military Field Testing Success


(Honolulu, HI) – Greenpath Technologies, a leading solar integrator delivering innovative renewable energy solutions in Hawaii, recently participated in the U.S. / Philippines Balikatan 11 Field Exercises held in early April this year at multiple Philippine locations.  The U.S. Marine Corp Forces’ Pacific Experimentation Center (MEC) supported the Balikatan exercise through technology insertions in the Field Training Exercise and Civil Military Operations and organized displays and demonstrations during the opening ceremony.  This exercise proved to be highly successful for Greenpath, where the company unveiled its new photovoltaic solar-powered man portable folding module that was evaluated and reviewed at Ft. Magsaysay and Camp Aguinaldo.

Greenpath participated in the new technologies segment of the exercise, displaying its LITE-PM folding PV module system, conducting data comparison and testing to competing models.  Greenpath’s PV module consistently charged the military standard issue batteries three times faster than the comparable models and even faster in cloudy conditions.  When tested side by side, the Greenpath system consisting of two batteries and two folding modules charged two batteries in three hours, versus the other system, also consisting of two batteries and two folding modules which charged only one battery at 50%.  On a day with only 50% sunshine, the Greenpath system fully charged two batteries in less than four hours while the other system charged only one battery to 40%.  In addition to holding a faster and more powerful charge, Greenpath Technologies’ folding module retains a smaller footprint than comparable modules.

James Chaney, inventor of the company’s PV folding module and Director of Greenpath’s R&D division attended the Balikatan event to present their technology to several different military divisions, including the U.S. Army National Guard based out of Guam, and the Philippine Army 51st Brigade from Camp Aguinaldo.  “Participating in this exercise before an authoritative military audience was a great opportunity to present our data testing alongside comparable models.  The results continued to support the superiority of our product.  It gives us much pleasure and a great sense of pride to know that we can locally develop a superior high-technology product that our troops abroad can effectively use,” said Chaney.

The LITE-PM system was evaluated by several notable individuals at the Balikatan Field Exercises, including the MEC’s Director, Experimentation Officer, Technology Lead, Renewable Energy Assessor, and the Hawaii-based ONR Officer.

Greenpath has been highly recommended to attend the Thai Crimson Viper field exercise testing held in Thailand in June, 2011 for further wartime testing and evaluation.

GreenPath Technologies is a native Hawaiian-owned and operated solar powered systems contractor and integrator, offering unique turnkey solutions in renewable energy for commercial, industrial, government, military, residential, and non-profit customers.  Recent projects include HawaiiUSA Federal Credit Union, Carrier Hawaii, Japanese Cultural Center of Hawai`i, J.H. Walter Cameron Center on Maui, and the Waialae Country Club.   GreenPath’s mobile folding

solar photovoltaic module will be manufactured locally and targeted for military war fighter deployment.   The company engineers some of the most advanced photovoltaic solar systems available today and invests heavily in research and development which has kept them at the forefront of renewable energy applications.

Solar Industry: New research on how PV Effects Residential Home Value

New Study Proves That PV Installations Contribute ‘Sizable’ Value To Home

Homes with solar PV systems sell for a premium over homes without solar installations, according to new research by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory.

Although the premise that installing PV will add valueto a home has long been promoted by installers and others in the industry, the new study – titled “An Analysis of the Effects of Residential Photovoltaic Energy Systems on Home Sales Prices in California” – confirms and quantifies this effect.

According to the lab, this research is the first to empirically explore the existence and magnitude ofresidential PV sales price impacts across a large number of homes and over a wide geographic area. Over the past few years, an increasing number of homes with PV systems have sold, particularly in California, but relatively little research has been performed to estimate the impacts of those PV systems on home sales prices.

Overall, the researchers found that homes with PV in California have sold for a premium, expressed in dollars per watt of installed PV, of approximately $3.9/W to $6.4/W.

“These average sales price premiums appear to be comparable with the average investment that homeowners have made to install PV systems in California, and of course, homeowners also benefit from energy bill savings after PV system installation and prior to home sale,” says the report’s lead author, Ben Hoen, a researcher at Berkeley Lab.

The $3.9/W-to-$6.4/W increase corresponds to an average home sales price premium of approximately $17,000 for a relatively new 3.1 kW PV system (the average size of PV systems in the Berkeley Lab data set), and compares to an average investment that homeowners have made to install PV systems in California of approximately $5/W over the 2001-2009 period.

“This is a sizable effect,” says Ryan Wiser, a Berkeley Lab scientist and co-author. “This research might influence the decisions of homeowners considering installing a PV system and of home buyers considering buying a home with PV already installed. Even new-home builders that are contemplating PV as a component of their homes can benefit from this research.”

The lab analyzed a dataset of more than 72,000 California homes that were sold between 2000 and mid-2009, approximately 2,000 of which had a PV system at the time of sale. The research controlled for a large number of factors that might influence results, such as housing market fluctuations, neighborhood effects, the age of the home, and the size of the home and the parcel on which it was located, the researchers note.

The resulting premiums associated with PV systems were consistent across a large number of model specifications and robustness tests. The research also showed that, as PV systems age, the premium enjoyed at the time of home sale decreases.

Additionally, existing homes with PV systems were found to have commanded a larger sales price premium than new homes with similarly sized PV systems.

“One reason for the disparity between existing and new homes with PV might be that new-home builders also gain value from PV as a market differentiator that speeds the home sales process, a factor not analyzed in the Berkeley Lab study,” says Berkeley Lab researcher and co-author Peter Cappers. “More research is warranted to better understand these and related impacts.”
