SolTech System AN EFFICIENT AND SMART SOLAR ENERGY SYSTEM

SolTech System AN EFFICIENT AND SMART SOLAR ENERGY SYSTEM

ATTractive SOLAR ENERGY SolTech Sigma With SolTech Sigma, we have created an efficient, tidy and simple solar energy system for single homes as well as for large residential and commercial buildings. With SolTechs own thermal absorbers, especially developed for our specific glass roof tile, installation is simple and overall system efficiency is high. An efficient, attractive and smart solar energy system Combined with SolTechs award-winning design and concept solution, we can now offer a solar energy solution that is both effective and elegant, SolTech Sigma, the energy efficient smart roof. The roof of most buildings, annually receive many times more energy from the sun than is being consumed in the building! With SolTech Sigma you can benefit from that energy, save money and get a beautiful new roof for your building at the same time! Simple and Ingenious Instead of traditional roof tiles made from concrete or clay, we use our specific SolTech tiles made of glass. The glass tiles are installed on the Sigma Modules, SolTechs specially developed liquid based absorber modules. The modules have an integrated, patented, carrying batten for maximized absorber surface as well as simple installation. The modules are interconnected on the roof to form a complete solar collector system. Generated solar energy is stored in the SolTech Therm Accumulator tank which is connected to the building s central heating system. This configuration enables the use of all the energy the sun provides first and the central heating system will step in to provide heating for those times when the sun does not produce enough energy. A flexible system The system can be integrated with any water borne central heating system or hot water system with ease, regardless of heating source. The highest efficiency is obtained when the roof is straight facing south, but southwest and southeast also works very well. The optimal roof pitch varies from every location, but generally a pitch of 30-60 degrees is recommended for Europe. Our minimum recommended pitch is 22 degrees. If you have a roof pitch less than this, do contact SolTech Energy for the design of an appropriate solution for you. Each installation is tailored to the specific building. SolTech Sigma can be installed on the entire roof or part of the roof, depending on customer needs and wants. When part of the roof is used as solar collector surface, we offer the customer a solution where the rest of the roof is covered with SolTech Power, our solar electric solution, or passive glass roof tiles for an aesthetic and uniform solution. 2 SolTech Sigma

Solar Energy made beautiful SolTech Techo Solar SolTech Techo Solar is our solar thermal module that combines the function of a roofing material with an effective solar energy solution. It is designed primarily for cement and brick based roofs which fits construction methods that are commonly used in the Mediterranean countries, Latin America, North Africa and many other countries. The SolTech Techo Solar (Solar Roof) is a patented bioclimatic architecture product with multi functionality. Primarily it s a building material, which can cover any type of building. Secondly it s a solar thermal system that maximizes the active area of the roof area. The result is a configuration which maintains the classic style of a tiled, sloped roof while also generating clean renewable energy. Simple and Ingenious Instead of traditional roof tiles made from concrete or clay, we use our specific SolTech tiles made of glass. The glass tiles are installed on the Techo Solar Modules, SolTechs specially developed liquid based absorber modules. The modules have integrated, patented, carrying battens for maximized absorber surface as well as simple installation. The modules are interconnected on the roof to form a complete solar collector system. Generated solar energy is stored in the SolTech Therm Accumulator tank which is connected to the building s central heating system. This configuration enables the use of all the energy the sun provides first and the central heating system will step in to provide heating for those times when the sun does not produce enough energy. A flexible System In the same way as our SolTech Sigma System the Techo Solar System can be integrated with any water borne central heating system or hot water system with ease, regardless of heating source. The highest efficiency is obtained when the roof is straight facing south, but southwest and southeast also works very well. The optimal roof pitch varies from every location, but generally a pitch of 30-60 degrees is recommended for Europe. Our minimum recommended pitch is 22 degrees. If you have a roof pitch less than this, do contact SolTech Energy for the design of an appropriate solution for you. 4 SolTech Techo Solar

The System is designed to be part of the buildings structure, with the option that it can either integrate with conventional tiles (classic ceramic or traditional concrete), or cover a full surface independently, depending on design, available area and energy needs for the building. Due to its light weight, 60 kg/m 2, its application is extensive and can range from porches, roofs, covered terraces, garages, car parks etc. The bottom layer of the Techo Solar is a high density insulation which keeps the energy conserved in the system, improves the overall energy efficiency of the building and is the part of the system that facilitates modular installation. The intermediate layer is made up of the solar collector and the hydraulic circuit, through which flows the heat transfer fluid and functions as the energy collection element of the system. Finally the top layer, which is the visible layer, is the SolTech Energy Glass Roof Tile. Its high transparency SolTech Energy Module & Tiles molded glass acts as a water proofing element, creates a sealed chamber for optimized function, allows the solar radiation to pass through and provides the architectural aesthetic of the product.

world leading solar cells SolTech Supreme A large Scale installation of our system S1 Thin Film solar cell - Front and back side World leading solar cells from SolTech Energy! SolTech Supreme are thin film solar cells that are designed differently from traditional solar cells. Through is revolutionary design, the solar cells have different properties converting light into electricity. High Efficiency Ratio SolTechs Supreme has a high, 12 %, performance ratio, comparable with traditional crystalline silicon cells. Better in diffused light SolTech Supreme cells have a much higher efficiency and yield in diffused light like dusk, dawn and light overcast. The SolTech Supreme solar cells work in a much wider spectrum of light that may be converted into electricity than traditional crystalline silicon cells, this result in SolTechs Supreme also producing electricity in diffused light. Less sensitive to high temperatures A traditional crystalline silicon solar cell loses approx. 0.48 % in output for each degree C that the panel temperature rises above 25 C. In clear sunlight with warm temperatures, the panel temperature will rarely be as low as 25 C, but rather 2, 3 or 4 times that or even more. SolTech Supreme will lose only approx. 0.21 % for every degree C. For this reason, SolTechs Supreme will have a higher output in higher temperatures than that of traditional solar cells. More kwh/w Better ROI The combination of high efficiency ratio (12 %), higher efficiency in diffused light and less sensibility to high panel temperatures results in that more energy, kwh, is produced per installed watt than traditional solar cells. Tests show that for regions like Scandinavia, Germany and southern China (same parallel as northern Africa), 5 10 % more energy is produced per W installed than for a traditional solar cell facility of equal output. That provides for a better ROI on the system. 8 SolTech Supreme

Solar energy with intelligence SolTech Supreme ST Wall installation using SolTech Supreme ST. SolTech Supreme ST can be ordered with different levels of transparency. SolTech Energy is proud to present SolTech Supreme ST. ST stands for Semi Transparent. This is a whole new way of combining solar energy with solar shading. With SolTech Supreme ST, SolTech Energy is now able to present a sustainable, intelligent and aesthetical solution for the combination of solar energy and solar shading. By applying the thin film in very narrow rows in the module, a shading effect is achieved, like sun glasses. Solar Shading and power generation at the same time Through integrating the solar shading into the glass roof, the need for air conditioning in the building reduces. However, if the shading can make use of the solar energy, an even greater benefit is reached. SolTech Supreme ST will therefore reduce cost on air conditioning through power generation! Tailored solar shading SolTech Supreme ST can be ordered with different levels of transparency, ranging from 90 % to 10 %. Since the need for shading may be higher for a glass roof, a low level of transparency may be chosen for more shading whereas a façade solution might require a higher level of transparency allowing for better view through the window. One of a kind solution With its revolutionary concept of combining a renewable energy source with semitransparent shading, SolTech Supreme ST is the natural choice for glass roof applications, store windows, winter gardens, atriums, shopping malls, patios and other buildings where you want to have; the light, the view, solar energy and less air conditioning needs. SolTech Supreme is truly a one of a kind solution and the only solution for many buildings. Insulated glass module In addition to offering a solar shading solution, SolTech Supreme ST may also be ordered as an insulated glass module. For buildings where there is a heating need and there are insulation requirements on the windows, the Supreme ST module can be ordered as an insulated module with argon filled spacing and a U-value of 1.3. Simple installation SolTech Supreme ST can easily be installed using leading aluminum glass roof or glass façade systems for creating a water proof and insulated climate. Through the use of leading suppliers of these systems, a global network of installers and suppliers can be found. It also facilitates for architects and designers to introduce these systems into future buildings and projects. SolTech Supreme ST 9
