The product range comprises the most high-end efficiency products. Highlights are the innovative bi-axial, astronomically-aligned tracking system as well as the companys off-grid portfolio. The Kirchner Solar Group photovoltaic mobile testing laboratory will also make its first public appearance, which will be exhibited at the outdoor area at booth FG.260.
The PV and CPV-tracker
The feed-in tariff reduction makes the issue of solar plant efficiency ever more pertinent. Recognizing the need for greater efficiency, the Kirchner Solar Group stands out with its development of astronomically aligned, bi-axial PV tracking systems: sonnen_systeme. They were jointly developed by the company and the inverter manufacturer SMA.
The astronomically-aligned navigation and the two freely moving axes guarantee that the sun radiation degree remains consistently at 90 degrees. Lars Kirchner, the CEO and founder of the Kirchner Solar Group, elaborates: Through our tracking systems our customers benefit from an up to 45 percent higher efficiency level in comparison to flattened-out rooftop PV installations. The free space underneath the tracker opens up space, which can be used, for instance, as a parking lot or for farming. The company understands itself as the world-market leader for bi-axial, astronomically-guided tracking systems. Kirchner has produced and installed more than 11,000 units world-wide so far.
The robust CPV trackers with their precise astronomically navigation are a particularly well-suited solution for regions with strong sunlight insolation such as found near the equator. In the regions around the so called sun belt, the CPV technology enables solar electricity for the lowest manufacturing costs in combination with the best possible temperature characteristics.
Solar Home Systems for off-grid appliances
A particular characteristic of photovoltaic technology is its decentralized applicability. One step further go self-sufficient isolated applications that provide its user with electricity that is independent from the national grid. The Kirchner Solar Group has been working on this market segment for many years and thus offers a broad spectrum of off-grid-appliances.
As Lars Kirchner points out: Our Solar Home Systems are developed especially for the energy demand of private households and municipalities in areas without access to a stable and reliable public grid. Thus, Solar Home Systems are a particularly interesting alternative energy supply route for developing countries, where expansion of the national grid system is costly. The electricity supply to underdeveloped regions reflects the spirit behind Solar Home Systems. However, those solutions can be used in a number of ways that demand self-maintained energy, such as for huts, holiday homes, caravans, boats and expeditions.
The Kirchner Solar Group mobile test-lab for solar modules MobiLab
The Kirchner Solar Group constantly develops new solutions with a view to making solar energy more efficient and powerful. This includes the latest company development, a mobile laboratory for solar modules. Right in time for the Intersolar the Kirchner Solar Group has once again underscored its commitment to deliver high-end quality products. The laboratory allows precision measurement of PV-modules by the Standard Testing Conditions (STC) Flasher which measures the voltage curve and the Power Maximal Power Point (PMPP).
Through the mobile measuring container, employees can location-independently carry out electroluminescence analysis from now on. Thereby the extent of microcracks, module damage, contamination, and inactive cell parts as well as contact failures can be measured. Thermographic metering further allows for measuring the electricity-induced thermal efficiency of a module with a thermal camera from afar. The thermal imagining system further detects solar cell short-circuits and contact failures between connectors and solar cells.
