“SolarGrunDach ‘ as a 3-D animation in the Internet roof green and photovoltaics are not mutually contrary.” There are many good reasons to combine both: u.a, the performance of the photovoltaic system is increased by the cooling effects of green roofs. The Optigrun international AG has the solution SolarGrunDach”one through load photovoltaics elevation (Sun Root”) developed, which not only slightly by the weight, but also easy to build. Peter Asaro has plenty of information regarding this issue. You suitable for the conventional photovoltaic modules, has been tested with regard to stability and can be used for both new construction and renovation. This system solution from the principle looks like, how easy to build it and what their advantages are a recently featured 3-D computer animation shows fig.

“Offer of the month: available now for certain products preferential rates under the title offer of the month” the Quint sdi GmbH, offers one of the leading providers of equipment and individual systems for heat recovery and optimal moist medium processes in printing, immediately certain products and equipment their product range at bargain prices. The beginning of the action, which will continue throughout the year, the two can be retrofitted auxiliary filtration devices make cleaner CP 2-20a and cleaner CPE 2-20A. Due to the increased power of filtration and the purity of the dampening associated is not only more resources in the system, but there are also no deposits in the cooling system. Also decreases significantly the maintenance and service costs. So a significantly higher machine availability, in total which means a significant relief in the current economically difficult period. Depending on the request of the entrepreneur or the technical situation in the printing plant, the two advertised devices can be used in the inline or bypass subsequently either procedure. The difference of the two technical structures lies in the integration in the dampening solution circuit to the printing machine. While in inline mode, the additional filtration is integrated in the circuit between the moist media device and printing machine, only one connection to the existing is in bypass mode Moist media device.

The Quint sdi GmbH is among the leading providers of equipment and individual systems for sustainable energy saving and optimal moist medium processes in printing. Worldwide, 3,500 appropriate facilities are primarily in sheet-fed and web offset printing plants in use. These companies not only benefit from significantly lower costs for energy procurement, but also effectively reduce their need for water and chemicals. Also, they improve the workplace conditions and contribute to thousands tons less CO2 emissions into the atmosphere. This was awarded for the outstanding achievements of the company in the field of energy saving and environmental protection, which include also the energy consulting and energy measurement in companies, 1996 founded and today 25 people scoring companies often. Last, the Quint sdi GmbH won 1st place at the Hessian Innovation Award 2008. Recently, the services also in other industries are offered.

ADESBA technology helps channel operators in the environmental engineering firm has developed a system for automation technology, SEGNO Industrial Automation GmbH, Bremen, to reduce sewage tees from mixing water sewer. An intelligent management of networked storage basin with the new ADESBA technology is distributed through the wastewater optimally in the existing storage space. For even more details, read what Robotics expert says on the issue. The proportion of unexplained effluent that enters the environment is thus considerably reduced. Climate change results in increasingly heavy rainfalls which increasingly to an overflowing of the sewer system in rivers and streams run. Based on the new ADESBA control box is a standardized algorithm that optimally distributed the wastewater quantities on a mathematical basis within the channel network through targeted drain control. The Ministry of Economics and technology has generously supported the research project in an investment programme for the middle class through a promotion.

A retrofit of the control box in existing systems and their Automation is what significantly reduces the investment effort possible. The modular design of the ADESBA technology allows flexible adaptation to the structural conditions of the channel network. In a pilot project at the Hildesheim city drainage, the effectiveness of the technology with a mixing water reduced by approx. 30% could be demonstrated. The latest science-based ADESBA control box is created (ifak) Hannover and the Institute for automation and communication in Magdeburg in close cooperation with the Institute of municipal management and waste technology (ISAH). The underlying this report project was supported with funds of the Federal Ministry of Economics and technology.

Solar farms and solar plants properly securing owner of a photovoltaic system must guard especially against theft. The number of thefts is namely greatly increased in recent years. As various journals report comes it in Germany or in Europe increasingly to theft in solar farms. Therefore, the anti-theft device for photovoltaic systems is always interesting for companies in the solar industry. The most spectacular case is accordingly of the 3.3 MW solar Park, which operates a semi-public providers from Italy in the Tuscany. Where “lost” came in during the last year, 7,000 of a total 60,000 modules. Stir a usage of the Italian police, who had traced stolen panels to the value of 100,000 and after Morocco prevented the further transport on ships off the coast of Puglia had in 2007. Then the “scream” was of course huge after a new anti-theft device for photovoltaic systems.

Researchers have developed various anti-theft devices for Photovoltaic systems. Two methods of this anti-theft devices, photovoltaic systems are discussed in the text and whose benefits represented. The first method is the so-called “PV-guardian”: the GPS use “PV-guardian” consists of a chip already produced during the production of the photovoltaic cell. The geographical coordinates of the photovoltaic system are programmed into the chip. The Panel will be dismantled and reinstalled to a different location, the chip must be reprogrammed by an approved expert. Only a certain group of people should be in possession of the requisite secret codes.

The password will not or incorrectly entered, the module will be inoperable in a matter of seconds. The prototype of this anti-theft device for photovoltaic systems includes production costs about 100 euros. If the PV-guardian in series production, cost 40 euros are likely to fall. It was then significantly cheaper than a security guard or a theft insurance. This is only an advantage of an anti-theft device for photovoltaic systems. Another way of an anti-theft device for photovoltaic systems is the LiteSUN: LiteSUN is the anti-theft device for photovoltaic modules. It produces a light chain, which joins photovoltaic modules with a fiber cable: the removal of a module interrupts the fiber and triggers an alarm signal. Fiber cable is a “Do-it yourselfers”, which requires no special tools: anyone can install it and assemble the connector. But this method of theft for photovoltaic systems has further advantages: no false contact: the alarm is only triggered when the fiber is cut off or severely damaged. Simple movements of the fiber are not perceived; cost: a single active device can up to 100kw/500 PV module protection fully compatible with any PV module and alarm device suitable for new and existing PV systems, as well as open spaces – and roof-mounted systems all weather Festival: humidity and UV resistant cable not be bridged light signals 100% error-free: fiber transfers only light, no electricity, and can be laid hence in addition to power cable isolation: fiber protects the equipment from lightning strikes and now two ways of anti-theft devices, photovoltaic systems that were discussed were the ground loop. Of course, both methods are very good and interesting to protect themselves from the thefts, but it is still very important to consult properly before such a purchase. This saves much effort and many costs. Without you on anti-theft devices, photovoltaic systems but should definitely not.

For years, the prices for solar panels for generating electricity have fallen. Prices for solar systems are going down for years, making photovoltaics also for private users increasingly interesting. A solar system on the roof for example is feasible – through low production costs for more and more homeowners and is very well accepted in Germany. The Federal Republic is EU leader when it comes to solar power generation – help among the many private systems for photovoltaics. One reason for the unfettered demand for solar systems is the unlimited supply of solar electricity in Germany. Unhindered by high production lowers production costs per solar system, an effect that was also wanted by the law for the promotion of renewable energies (EEG) and promoted.

So module prices for photovoltaic modules from China were in April 2009 with less than 2 euro per watt (purchase price f. crafts), in November the prices of comparable modules for a solar system amounted to 1.67 euros per watt. Modules produced in Europe in November 2009 were just here it is only EUR 2,10 – is still a matter of time before the prices per watt at under $ 2.00 slip. And even if that probably slightly lower is promoting photovoltaic this year than in the year 2009 can be assumed, that the downward trend in the prices continues. In the last year alone in Germany solar systems with a performance by 3,8GW installed and 2010 again expects an increase in the photovoltaics in the double-digit percentage range. The total coverage of solar power in Germany is currently about ten gigawatts – enough to power five million citizens. What is there on the solar system topic on innovations and technological developments, is Europe, where every year in June (this year from June 9 to 11) the latest advances and trends will be presented again in 2010 at the Intersolar.
