Photovoltaics

The US General Services Administration in Suitland, Maryland operates a 100 kW thin film pilot unit. In comparison with conventional photovoltaic systems equipped with silicon wafers, here glass substrates coated with thin films are used.

The acquisition of America’s Applied Power Corporation provides SCHOTT with a ticket to a market with good long-term growth potential.
The goals are ambitious. By the year 2010, SCHOTT aims to be the number one or number two player among suppliers of hotovoltaic systems. The new SCHOTT subsidiary has more than 20 years experience in the market, which can now be combined with the parent company’s well-developed global sales network. Why photovoltaics? This is an obvious question for those who know SCHOTT as a manufacturer of special glass. “The hotovoltaics market is growing at a rate of 20 to 25 percent a year,” said photovoltaics segment manager Michael Harre. “This offers SCHOTT good opportunities for development. For a start, photovoltaics has a lot to do with glass and glass handling. This new business is also an excellent fit with our Vision 2010, the core purpose of which defines that we will improve how people live and work through expert solution. And finally, photovoltaics is now a global market. SCHOTT’s international network puts us in a very good position to tackle the market.”
Specialist in Photovoltaic Arrays
SCHOTT Applied Power Corporation (SAPC) is already a leading supplier of photovoltaic systems in the United States. As a system integrator, the company develops and markets individual complete systems. The components, such as photovoltaic modules, batteries and DC-AC inverters, are purchased from various suppliers. From the earliest years of its existence, SAPC has belonged to a small group of companies selected by the US government to carry out publicly-funded photovoltaic projects. Today the SCHOTT subsidiary is known for its many years of experience but also for its broad range of products and services. Larger past projects include the electrification of rural areas in Brazil, turnkey systems for the operation of telecommunications systems, the conversion of solar energy into electricity for buildings connected to a municipal power supply and consumer goods applications (e.g. for private mobile homes and cabin cruisers).
Solar Power – makes Economic Sense

In a vast and thinly populated continent like Australia, photovoltaic generators are also used in telecommunications as they are considerably more durable than diesel generators. Solar powered generators usually have an operating guarantee of 25 years. “Two thirds of the photovoltaic market is also attractive from a purely economic point of view”, states Harre. This also uarantees companies operating in this business a certain degree of autonomy from political decisions. In the long term the trend is towards environmentally friendly energy. According to a study carried out by Shell, the climate protection target to significantly reduce carbon dioxide emissions can only be achieved by supplying half of the world’s energy requirements with renewable energy by the year 2060.
A large market for photovoltaics is opening up in the structurally weak countries of the Third World. Here solar energy offers the only possibility of providing billions of people with electricity for lighting, refrigeration and communications – and that without placing additional burden on the environment. This too is an important reason for SCHOTT’s commitment to photovoltaics. SAPC’s experience in this area provides an excellent foundation. It has already carried out several projects in rural areas in Brazil, Mexico, India, Bolivia, Kenya and Sri Lanka.
