Highest yields under real conditions, even when they are unfavourable. In order to make good on this claim, throughout its history Solar Frontier has conducted extensive research and made many innovative breakthroughs in CIS technology. The company has carried out pioneering work in solar energy since 1970, and has accumulated unparalleled expertise in research, development and manufacturing of solar panels.
Solar Frontier’s SF145–170 PowerModules S-series offers the highest conversion efficiency of any mass produced thin-film module, up to 13.8 %. All modules are RoHS compliant and cadmium and lead-free. Fewer production steps and raw materials also mean an industry-leading energy payback time of less than one year.
 Salt mist occurs especially in coastal regions and places demands on the module surface over many years. Solar Frontier CIS modules have been successfully tested for these heavy demands, and can therefore also be used in coastal regions. Resistance to salt mist corrosion |
 Crystalline PV modules are made from wafer-thin silicon cells, a very brittle material. Strong mechanical stresses can tear or even break them. The photovoltaic layer of the CIS module is also wafer-thin, but not brittle. Therefore microscopic cracks cannot occur due to stresses in Solar Frontier modules. No microcracks |
 Increased concentrations of ammonia can occur in agricultural environments and these can damage the solar module. Solar Frontier CIS modules are subject to documented tested for use in such regions and can be deployed without any problems. Resistance to ammonia corrosion |
 Solar Frontier CIS modules are produced using so-called sandwich construction, in which the PV layer is sealed and protected on the top and bottom by two glass panels. In addition, the rear side has an additional film seal. This robust construction ensures longevity even for heavy demands due to weather. Robust glass / glass / back sheet |
 PID stands for potential induced degradation and means that leakage currents in the modules can lead to permanent power losses. This effect occurs primarily with crystalline modules, but not with Solar Frontier CIS modules, for technological reasons. No PID |
 Harmful substances, such as lead or cadmium, are used in the production of some PV modules. Solar Frontier CIS modules are free from any environmentally polluting harmful substances and even meet the strict RoHS guidelines, which regulate the use of harmful substances in products. No cadmium No lead |
 Conventional crystalline PV modules possess hundreds of soldering points between the individual cells. If these have been poorly processed, so-called hot spots can occur, which can lead to power losses. Solar Frontier CIS modules are based on fully coated thin PV layers and therefore have no soldering points. Thus no hot spots can occur. No hotspots |
 With many standard silicon modules the individual cells and silver conducting paths can be seen. In addition, many of these modules have a greyish or bluish tinge. The module area and frame of the Solar Frontier CIS modules in contrast are black and can therefore be integrated aesthetically into many roof surfaces. Superior aesthetics |
SF145–170 PowerModules are shipped in cardboardfree packaging and use recyclable corner pieces.

1) Values measured under Standard Test Conditions “STC” defined by IEC norm (1,000 W/m² irradiance, 25°C module temperature and air mass 1.5). Isc and Voc are within ±10% tolerance of the rated values at STC. If measured at a later point in time after shipping from the factory, Pmax may have a tolerance of +10% / –5%. Module efficiency at 200 W/m² irradiance is typically 98 % (±1.9 %) of efficiency under STC.
