Photovoltaic Systems

DENEX Congress shows examples of successful production of solar electricity is has long been attractive to private households thanks to the ER-renewable energies Act (EEG). Also company now increasingly discover, which economic potential of Po holds the use of their large roofs. Lower module prices and offers on the photovoltaics market, the planning, Mon day, financing and services conveniently from a single supply, be always in teressanter the installation of large roof PV systems. The Conference for photovoltaic systems on industrial and commercial roofs, which takes place on the 17.11.2011 within the framework of the exhibition and Congress DENEX in Wiesbaden, informed ENT decision makers in companies, which are economic, commercial-chen and organisational issues. In addition to private houses and agricultural buildings, industrial and commercial roofs are the third largest area of application for photovoltaic systems in Germany.

Production halls and logistics centres, but also roofs of hospitals or sports facilities, for example, offer plenty of room for the use of photovoltaics. Speaking of large photovoltaic systems from a nominal capacity of 30 kwp. This environmentally-friendly type of electricity generation contributes to sustainability, but long associated image winning no longer is the decisive argument. Companies secure the operation of PV systems in addition an attractive and safe return. Large-scale photovoltaic companies such as Michelin, Liebherr, VW, BMW and Aldi have installed on their roofs. Often the costs pay for themselves already in a few years. A company intends to use its roofs to generate electricity are however several questions to clarify. What roofs are due to alignment, inclination and in particular capacity? What funding model is the most suitable? Would the company operate the facility itself or leaving it up to a tenant? What measures for the safety of the installations are to meet? The offer of the solar industry for industrial and commercial customers is great.

Whether as a roof system, on solar carports, the lateral electric of the staff can provide power, or integrated into the building facade: use of the possibilities of photovoltaics are varied. In addition to the traditional rooftop installations of the photovoltaic Dunnschichtlaminaten market also offers solutions for low duty or unfavourably aligned roofs. The Congress provides an overview of technical questions, solutions to the financing and insurance, as well as safety requirements for photovoltaic systems on industrial and commercial roofs, which takes place on the 17.11.2011 within the framework of the exhibition and Congress DENEX, the owners of large roof areas. Professor Martin Maslaton, lawyer and specialist in legal issues related to the renewable energy questions on legal basis and compensation. Also, two of the largest rooftop systems in Germany are presented the Congress participants: the photovoltaic projects the Michelin Tyre works and the installation of the Liebherr plant in Biberach. Michelin has leased the roofs of several German locations. On the other hand took over the tenant the cost for roof renovation and installation of PV systems – a win-win situation. According to the competent project manager Sven wind h Michelin by linking the processing of roofs with the installation of photovoltaic systems could save a single-digit millions. He will report details in the Congress. Arbeitsgemeinschaft Industriebau e.V. (AGI) is involved as non-material carrier of the Congress. The DENEX, trade fair and Conference for decentralized energy systems, intelligent energy distribution and efficient use of energy will be on 17th and 18th November 2011 held under the auspices of Philipp Rosler, Federal Minister of Economics and technology, and Lucia Puttrich, Hessian Minister for environment, energy, agriculture and consumer protection in Wiesbaden.

Cadbury Energy

Cadbury factory reduces energy consumption and operating costs for new dehumidification technology a chewing gum factory of power subsidiary of Cadbury Adams has the company reported by realized a new dehumidification system compared to conventional systems, their energy consumption by no less than 60 percent and operating costs by an extraordinary 50 percent. Initially, Cadbury-Adams, tried to preserve these conditions by using the installed sorption wheel, but the wheel tended to emit heat, where the procedures needed substantial additional cooling. Under the strict production conditions and the high outdoor humidity and temperatures, the sorption rotors had to be replaced every 3 to 5 years. For these reasons, a dehumidification system was replaced according to the principle of the sorption rotor by a so-called ADVANTIX system, which operates on the principle of liquid desiccant. Chewing gum production requires a strict control of humidity and temperature conditions. The chewing gum production is a multi-step process, where each one different temperature and humidity required. With the installation of the Israeli ADVANTIX system, the chewing gum manufacturer in the location was annually 300,000 KW, corresponding to 60 percent, to save on energy costs.

The cost for the setting up of the system were 11 percent lower than for equipment with the sorption rotor, a return on investment (ROI) of 2.3 years and reduced operating expenses, so most effectively. The company reduced its maintenance costs and thus again inexpensively produced an excellent and popular product. ADVANTIX systems are used worldwide. These systems are based on a liquid dry system on the physical basis of the water in the dead sea. The system uses a non-toxic salt solution of water for the dehumidifying and air cleaning, which largely eliminates bacteria, micro-organisms and odors. There is a procedure to the cooling and dehumidification of air, which is based on the use of a hygroscopic, saturated solution of lithium chloride. The solution acts as a Sorbents used honeycomb structures of the air to be dried. The desorption of the solution is done in a separate process, which is operated with via heat pumps of heated Sekundarluft (E.g.

outdoor air, exhaust air, etc.). The solvent circulation is self-contained and requires no additional media with the exception of electrical energy. The ADVANTIX program consists of 3 different variants, the a) working alone on a current basis, b) as and/or in addition based on renewable energies, such as PV, heat, etc. and c) only on renewable energy. Thus, ADVANTIX is an interesting variation in the area of decentralized cooling and dehumidification of sorption wheels cannot be used. This applies in particular, because it is a stand-alone system, which bypasses the problem of condensate removal. But also in the area of the central air conditioning applications are possible especially due to the high COP values. ADVANTIX systems is a leading manufacturer of air conditioners and dehumidifiers, the very high Energy savings in commercial and industrial applications. As a pioneer in the use of liquid desiccant, ADVANTIX provides powerful air conditioners and dehumidification systems with cooling, control of humidity, significant energy savings and clean air free from allergens, bacteria and mold. With competitive investment costs for new and retrofit applications, ADVANTIX offers compelling economic efficiency, better performance, and an improved environmental performance.
