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.
