Partnership to Increase Power Generation Efficiency for SolarManufacturers in Japan and China

TOKYO, Japan and REDWOOD CITY, Calif., February 23, 2010-Hitachi High-Technologies Corporation (TOKYO:8036), a subsidiary of Hitachi, Ltd. (TOKYO:6501, NYSE:HIT), and XeroCoat, Inc., a California-based solar energy company, today announced a strategic partnership for the distribution of XeroCoat's anti-reflective coating solutions in Japan and China. With this partnership, Hitachi High-Technologies and XeroCoat aim to capture a leading share of the solar power generation market through the sale of anti-reflective coating equipment and materials to solar module and glass manufacturers. The cost benefits and other advantages offered by antireflective coatings are expected to spur their rapid uptake. According to Hitachi High-Technologies, 50% of all solar modules are projected to have such coatings by 2015. In 2010, according to Nomura Research Institute, the solar power market is expected to deliver total power output of roughly 8,800 MWrepresenting a high annual growth rate of 19%. By 2015, market scale in terms of power output is expected to be around 21,000 MW.

"With XeroCoat's anti-reflective coating solution as part of our portfolio, we have broader access to the solar market and can expand our presence in solar manufacturing factories in the global market," stated Mr. Masumi Miyauchi, Senior Vice President and Executive Officer of Hitachi High-Technologies Corporation.

The cost of solar power generation is relatively high compared to other power sources, since only about 20 percent of the collected solar energy can be converted into electricity. This constitutes a significant barrier to full-scale adoption of solar power. For this reason, attention is being paid to ways of reducing the amount of light reflected by the protective glass on the surface of solar modules by applying an anti-reflective coating. This technique makes conversion to electricity more efficient by enabling greater transmission of sunlight.

XeroCoat: The Most Cost-Effective Watt on the Solar Module

The glass surface of solar modules typically reflects more than 4% of incoming light. The XeroCoat anti-reflective coating is a proprietary material that can be manufactured relatively easily at room temperature and in non-vacuum conditions. After coating and curing, silica is chemically bonded to the glass surface, keeping light reflection below 1%. Utilizing the XeroCoat coating, solar module makers can expect a 3% increase in peak power output and a 4% increase in energy produced on a kWhr basis. XeroCoat's turnkey coating system is simple, compact, environmentally friendly and energy efficient, making it compatible with existing manufacturing processes throughout the supply chain. The XeroCoat anti-reflective turnkey coating system has application to the entire range of solar energy technologies, including crystalline silicon and thin-film photovoltaics, concentrating photovoltaics, and solar thermal devices.
