Most of our construction workers are experienced employees of BELECTRIC to avoid dependency to subcontractors. This unique point ensures high quality installation and hold exactly the construction time schedule. renewable energy systems. Through our extensive research program, we have been able to introduce a number of innovations into almost all components of a solar power plant, making it more efficient and reliable to operate, and less complicated to construct. ADIA inverter topology Invented by BELECTRIC CEO, Bernhard Beck, the ADIA inverter topology replaces the usual central or string Therefore, the quality of the cabling and the connectors has significant influence on system effectiveness. BELECTRIC has invented a cable split manufacturing process by means of contacting and encapsulating methods that virtually eliminate losses and allow for extremely durable connections at the splice. Special materials guarantees durability over several inverters of a solar power system by a pool of inverters decades - even in rough environment conditions. that are interconnected with an intelligent current routing system. That way, the number of active inverters can be varied according to solar imission. The inverters that are active can operate at their optimum efficiency, which increases the overall system output. This technology has been successfully demonstrated at the Integrated Photovoltaic Demonstraction Site Dimbach, a large-scale photovoltaic project that was subsidized by the Ministry of the Environment, Nature Conservation and Nuclear Safety of the Federal Republic of Germany. ADIA has been licensed for production Partially sunlight and precipitation can still reach the ground - allowing the local vegetation to persist. to the German inverter manufacturer PADCON and is included in large-scale solar power plants.

3 Superior system performance through innovative module technologies As part of an integrated system, the solar modules are crucial to the overall effiency of a solar power plant. Only state-of-the-art thin-film solar modules are used in the construction of our utility scale systems. They offer a number of advantages over conventional silicon-based technologies. BELECTRIC sources solar modules from a variety of manufacturers and will incorporate the best price/performance solution based on each project s unique requirements. First Solar - high performance in a wide variety of climatic conditions Beck Energy was the first system integrator in Europe who has utilized the First Solar thin-film technology. These thin-film solar modules are supplied by Blitzstrom GmbH, Germany, who introduced First Solar modules to the European market in 2003 and became First Solar s first volume customer and partner. Over the years Blitzstrom and First Solar have built a strong and lasting collaborative partnership upon which BELECTRIC is able to draw. The module technology does not rely on silicon as a semiconductor at all. This, and other improvements, offers a number of advantages VDC System Voltage - Nanosolar high-power thin-film modules: Nanosolar is the industry s best-funded private manufacturer of solar electricity cells and modules. The company is known for its breakthrough capability of simply being able to print a solar cell based on CIGS, the intrinsically most stable and efficient thin-film semiconductor. The result are cells that can be produced with unprecedented throughput and cost efficiency. The Nanosolar Utility Panel was designed in close collaboration with BELECTRIC and includes a number of features that set the standard for module technology for utility-scale deployments. Nanosolar thin-film modules at a glance: High nominal power paired with the advantages of thin-film technologies: The Nanosolar Utility Panel is a high-power panel with up to 220 Wp nominal power. First Solar thin-film module technology at a glance: Stable performance even at high temperatures: With silicon solar cells, the efficiency drops as solar imission increases and temperature rises. With FS technology, this effect is dramatically less pronounced, giving significantly more efficiency during the hot noon hours of the day. Excellent efficiency in unfavorable weather or light conditions: FS solar modules are far less affected by deteriorating light conditions, such as in bad weather or during the morning and evening hours. Climate protection during production: Thanks to the reduced consumption of raw materials and energy during manufacturing of the First Solar modules, production also accounts for a very positive environmental balance. Investment safety: High rated output (80% for 25 years) and the no-cost Collection and Recycling Program by First Solar guarantee an attractive and uncomplicated solar investment. First Solar thin-film solar module 1500 V DC system voltage: As a high-current module certified for an industry-first 1500 V DC system voltage, it affords an extensive higher panel array length than conventional modules. High stability and material strength: By using high-strength glass in the back and the front a 70% larger spanning distance between mounting rails is possible, relative to conventional thin-film panels. This enables a very resource-friendly type of substructure. Quality by 50 years experience - Sharp s microamorphous silicon thin-film modules As a solar specialist with 50 years experience in photovoltaics, Sharp makes significant contributions to groundbreaking progress in solar technology. The NA series of thin-film photovoltaic modules consists of an amorphous and a microcrystalline silicon layer. This microamorphous tandem structure not only absorbs visible light but also the invisible portion of the sun light. This makes especially efficient use of solar energy. All module types of the Sharp NA Series offer optimum system integration, in terms of both technology and economy, and are suitable for installations in gridconnected PV systems. Innovation on 5,7m² - Masdar PV s amorphous silicon thin-film modules: Masdar PV develops and manufactures thin-film photovoltaic modules with a very attractive cost-benefit ratio. The amorphous silicon technology affords a photovoltaic application in free-field solar power plants and large-scale roof-mounted pv systems. Compared to conventional silicon pv modules, the Masdar a-si modules achieve higher energy yields at high external temperatures and under diffuse light conditions. Sharp NA product series at a glance: Innovative microamorphous tandem structure: Patended tandem structure with an amorphous and a microcrystalline silicon layer offering a stabilized module efficiency of 9.5 %. Solar energy at cloudy weather: The thin-film structure lets the pv modules become more insensible of temperature increasings. According to other thin-film technologies the Sharp structure delivers excellent energy yields under diffuse light conditions. The production lines at Masdar PV allow the manufacture of solar modules in size of up to 5.7m². Thereby this factor gives system integrators the flexibility to adapt the photovoltaic module size to their particular system installation conditions. The excellent cost performance ratio paves the way towards making thin-film solar energy competitive with conventionallygenerated energy and to make a sustainable contribution to the climate-friendly generation of our future power requirements. 4 5

4 Straight module rows with BELECTRIC substructure Inverter Systems - the heart of our solar power plants Compared to many competitors, the substructure of our solar power systems is exceedingly simple and sturdy at the same time. It consists of only 3 standardized steel, wood and aluminum parts. All components are of heavyduty industrial quality, impervious to any physical influences and designed to withstand outdoor conditions for entire life span of the plant. Thanks to the ideal combination of the straight-line generator block and our advanced inverter technology BELECTRIC solar power plants achieve a superior performance ratio. Advantages of the BELECTRIC substructure: Optimum orientation of the solar modules: Accurate linear (laser) alignment of the modules allows for the same incidence of light for every solar module. The module rows are positioned in a calculated distance from each other, such that they do not cast a shadow on one another during the morning and evening hours. Preservation of vegetation: Through the low degree of ground sealing by the substructure and due to the semi-opaque generator block continuous preservation of vegetation is ensured. An accurate replication of the planning: Through systematic construction by means of special developed machinery the plant is accurately positioned on the ground, exact to the milimetre, which allows for unlimited size of the plant. BELECTRIC s PV power plants generate direct current (DC) which is then converted into alternating current (AC) and fed into the grid through the inverter. The optimal performance of the inverter is crucial for the overall efficiency of the photovoltaic system. It is important that the output of the inverter match the power frequency and voltage of the utility grid. BELECTRIC s inverters constantly and automatically monitor and adjust those parameters for optimal performance at all times. The failure of an inverter component can cause significant production yield losses at the system level. BELEC- TRIC inverters are fitted with a comprehensive set of safety, redundancy and control features that allow the solar power system to continue operating even in the unlikely event of a component failure. In such a case, a sophisticated control circuit automatically assigns a working device to the functions of the damaged device and logs relevant data for later analysis. With those unique features, BELECTRIC inverters minimize the impact of a technical problem on the overall system efficiency.
