PES had a great interview with Oliver Strecke, CEO and Marco Thesing, CSO and business development manager at viamon. They have amazing security solutions, where trace and catch are strong deterrents. TRAPS came on to the market last year and is proving very successful. They have a bright outlook on the future, with many orders on their books. Are your solar installations secure? Read on to find out what‘s on offer. PES: Welcome back to PES Solar/PV magazine. We have been following viamon for quite a few years now, so it’s good to have the opportunity to talk with you. Would you like to begin with a company overview? Oliver Strecke: viamon has been working on the question of how to develop intelligent systems to secure PV systems since 2009. The basis is a vibration sensor that we developed especially for the needs of the PV industry. It can be used to secure solar modules and additionally, determine their position worldwide via GPS if they are stolen. That was the beginning. On this we systematically expanded our portfolio of sensors, e.g. with PIR sensors (passive infrared). On the one hand, we have always analysed the experience we have gained in the course of

New PV technologies make it possible to create more diversity to the utilization of solar energy. High efficiency, low cost and good looks of PV applications make it feasible to integrate solar power to new products and environments. Any self-powering object creates a local energy source. Solar energy can be used in many building integrated PV (BIPV) applications, such as facades, window structures or balconies. All vehicles are potential producers of solar energy. In principle, any energy-requiring object under the sun could produce PV power. Integrating PV can bring new value-adding features to products or even create completely new products. Producing local off-the-grid power will be the future. Now, is the time to redefine solar technology and make it a natural part of the environment. Valoe´s integrated solar technology meets new challenges There are no off-the-shelf products for integrated PV applications. The traditional cell and module designs cannot meet the various demands that the integrated PV will face. If PV is integrated into vehicles (VIPV), they need to survive vibration and to be shock and wear resistant. The weight of the module needs to be as light as possible and the PV element must be flexible and adjust to the surface form. Survivability,

With the steady growth of solar power and the increase of PV plants worldwide, a new series of PV modules, suitable for 1500-Volt systems, is on the rise. The higher demand for the latest, ‘1500 Volt ready’ generation of PV connectors from Stäubli Electrical Connectors, raises the question of the interchangeability of the new MC4-Evo 2 with the Original MC4. Along with the growth of the worldwide demand for energy and the need for replacing fossil fuel energy generation technologies, the renewable energy sector added 176 GW of power generating capacity globally last year, accounting for 72 percent of all power expansion during that period1. Main drivers behind this growth are the trend toward decarbonization and the overall electrification of appliances and industries. Solar energy contributed with more than 60 percent to this rise as it was able to generate a cost-competitive solution in regard to the needs. Important technology innovations and cost reductions accompany and support this market development that experienced a steady but very fast rise during the last 10 years. A 1500-Volt PV system design offers investment cost benefits over traditional system designs in large-scale PV plants. This leads to an increase of 1500-Volt systems being implemented during the

SolarCleano has been developing and selling robots to clean solar panels for 3 years. Based on the cleaning experience of its founder, Pol Duthoit, it created a robot usable by lone workers. Along the way, SolarCleano made a few discoveries that helped it tackle more issues. Solar panels exist in all shapes and sizes When the main SolarCleano F1 was developed, the objective was simple. A robot that could be used, unmounted and displaced by one person. It was already known that providing a power supply that would work independently on the robot would be a great add-on. Indeed, not every installation provides power sockets, and carrying a generator, or even just electricity cable, can prove to be a huge inconvenience. SolarCleano therefore developed a machine that would be dismountable, remote-controlled and battery-powered. Soon, it also appeared necessary to develop pads that would allow the robot to clean steeper panels, most installations in Europe being tilted for instance. The key to this balance was the pads placed on the Solarcleano robot. With constant innovation, we now offer a robot capable of climbing 25° steep slopes. Also, 4 types of brushes are available, depending on dirt type. They can be combined at will. For steeper

Powerful vacuum technology and reliable tightness control for improved efficiencies of solar receivers When solar energy for electricity generation is discussed, photovoltaic systems most often come to mind. However, concentrated solar power systems are gaining popularity as an interesting alternative. In this type of power plants, collector systems concentrate sunlight and collect it on an absorber pipe. A heat transfer fluid in these absorbers or receivers transports the energy to a turbine which is connected to an electrical power generator. This type of power plant is installed in regions that offer high levels of direct sunlight irradiation, for example, in Spain, the US (California and Arizona), and North Africa (Morocco). More recent installations are spreading all over the world including facilities in India, Israel, the Arabian Peninsula, South Africa, Australia and China. The technology Various concentrator technologies are using parabolic troughs, solar power towers, Fresnel reflectors, and hybrid systems using both solar power and synthesis gas as an energy source. The majority of installations is using parabolic troughs. In a solar thermal parabolic trough power plant, parabolic shaped mirrors concentrate solar radiation in an absorber pipe, the so-called receiver, positioned at the focal point of the reflectors. A heat transfer fluid such as

The performance degradation of solar modules Renewable energies are among the most important sources of electricity in Germany. Their expansion is a central pillar of the energy transition. Solar energy is one of the most significant renewable energy sources. Photovoltaic systems and solar parks represent an ever-increasing share of global energy production, because photovoltaics offer many advantages: extremely low operating costs and reliable yield forecasts; they do not require extensive construction measures and do not produce either pollutants or noise. Photovoltaic systems are also becoming particularly attractive in terms of their service life, which is now specified at 20 to 40 years. This depends primarily on the quality of the individual components. The quality of the solar modules, inverter and mounting frame is therefore crucial. The service life of the PV system is also determined by factors such as professional planning and design, the execution of the installation, and regular maintenance and servicing. A problem that now occurs in many PV systems and considerably impairs their service life is Potential Induced Degradation (PID) – the performance degradation of solar modules. As a result of negative voltage between the solar modules and the ground potential, there is a successive reduction in performance,
