See-thru spray-on technology turns ordinary glass surfaces into electricity-generating SolarWindows™, able to outperform rooftop solar by 300%.
Burtonsville, MD – November 1, 2010 – New Energy Technologies, Inc. (OTCBB: NENE) announced today that Florida Solar Energy Center (FSEC), a leading American certification and testing laboratory for solar products and equipment, has validated the Company’s power production modeling calculations for its novel, SolarWindow™ technology.
SolarWindow™ is the first-of-its-kind see-thru glass window capable of generating electricity, and able to outperform conventional rooftop solar module installations by more than 300% when applied to the facades of commercial tall buildings and skyscrapers.
Engineers modeling a 40-story building, similar to Tampa’s landmark “100 North Tampa,” estimate annual cost-savings of $40,000 to $70,000 when installing New Energy’s SolarWindow™ to exposed window facades. In contrast, mounting today’s popular poly-crystalline silicon modules rack-mounted on the rooftop produces only $20,000 in energy savings per year.
“We have long anticipated that applying SolarWindow™ to exterior glass surfaces of commercial towers could generate energy savings several-fold greater than today’s rooftop solar systems,” explained Mr. John A. Conklin, President and CEO of New Energy Technologies, Inc. “It’s wonderful to have these power modeling calculations now validated by FSEC, a highly-respected independent solar testing agency.
FSEC engineers reviewed numerous variables associated with the design basis and guidelines used in New Energy’s SolarWindow™ electrical power and financial model calculations, including:
- Building Area and Height – These variables account for the structure’s length and width, and allow for modeling of the number of building stories and calculation of “total viewable window surface area”;
- Number of Building Sides Available – This allows for calculation of SolarWindow™ power output based on various window exposure configurations;
- Peak Sun Hours – The number of hours required for a day’s total solar irradiation to accumulate at peak sun condition (PSH/day);
- Annual Building Energy Demand – The amount of energy required to power a building (kWHr/Yr);
- Roof Area – This calculation allows for comparison of SolarWindow™ against rooftop solar installations, and considers an “open array arrangement” for such systems; and
- Solar Offset Desired (Solar Fraction) – The percentage of a building’s energy requirements that can be met (satisfied) by a solar energy system. A Solar Offset of 100% means the entire building energy requirement is satisfied by the renewable energy system.
Following their review, FSEC engineers concluded that calculations in New Energy’s SolarWindow™ power output calculations model are “…reasonable and free of any significant errors.”
Florida Solar Energy Center is one of the nation’s leading certification and testing laboratories for solar products and equipment. The center’s expertise is based on nearly 30 years experience conducting solar energy certification and testing programs, the accreditation of PowerMark Corporation (PMC) and partnerships with such national associations as the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), The National Association of State Energy Offices (NASEO), and the Solar Rating & Certification Corporation (SRCC).
FSEC is renowned for solar testing, and has a long-standing history of certifying both solar hot water and photovoltaic (PV) modules. FSEC-certified PV modules include products by industry leaders such as: General Electric, Mitsubishi, Sanyo, Samsung, Sharp, BP Solar, DuPont Apollo, First Solar, and Suniva, Inc.
SolarWindow Technologies, Inc. is a developer of next generation, transparent electricity-generating SolarWindow™ coatings.
SolarWindow™ coatings generate electricity on see-through glass and flexible plastics with colored tints popular to skyscraper glass. Unlike conventional systems, SolarWindow™ can be applied to all four sides of tall towers, generating electricity using natural and artificial light conditions and even shaded areas. SolarWindow™ uses organic materials, which are dissolved into liquid, ideal for low-cost high-output manufacturing; and is the subject of a patent pending technology.
The company’s Proprietary Power Production & Financial Model (Power & Financial Model) uses photovoltaic (PV) modeling calculations that are consistent with renewable energy practitioner standards for assessing, evaluating and estimating renewable energy for a PV project. The Power & Financial Model estimator takes into consideration building geographic location, solar radiation for flat-plate collectors (SolarWindow™ irradiance is derated to account for 360 degree building orientation and vertical installation), climate zone energy use and generalized skyscraper building characteristics when estimating PV power and energy production, and carbon dioxide equivalents. Actual power, energy production and carbon dioxide equivalents modeled may vary based upon building-to-building situational characteristics and varying installation methodologies.
