Solar panels have proven to be a wise, future-proof investment in terms of economy and ecology. But just like any other technology, failures may occur. Thermal imaging cameras are an ideal for quick detection of those failures. Heinz Simmler, owner of Swiss photovoltaic inspection company Energie Netzwerk, is an avid supporter of this technology.Thermal imaging can provide owners and installers of solar panels an indispensable look at the interior of solar modules and the construction of the photovoltaic system. Defective cells, junction boxes, cables, inverters or incorrectly connected modules can be localized with high-resolution thermal imaging cameras. Energie Netzwerk, based in Bachenbülach, Switzerland, is specialised in photovoltaic thermography and a certified inspector according to the construction and electrical thermography standard EN ISO 9712."After gathering many years of experience with the installation and construction of solar panels for a large company, I decided to start my own company with a partner in 2014," says Heinz Simmler. "Before that, I had already worked with the company Emitec Messtechnik AG, a consultancy firm and distributor of FLIR cameras. This is how I got acquainted with the power of thermal imaging. And when it was time to buy a thermal imaging camera ourselves, there

In order to increase the profitability of wind turbines, components also have to come down in price - and that includes the sensors. But quality must not suffer as a result. Kübler's Markus Brunner, Global Industry Manager Wind, explains how smart design is maintaining high standards and maximising profit.Cost pressures during the construction of wind turbines have grown considerably. In order to increase the profitability of wind turbines, the components have to come down in price. This also applies to the sensors. However Kübler is able to demonstrate that cost pressures on wind turbines and the highest demands that are placed on them do not have to lead to a conflict. The company is developing and manufacturing encoders for a wide range of speed measurement and positioning tasks within wind turbines. Encoders used for speed control carry out their role at various places in the drive train of the turbine. Bearing-free magnetic systems can measure the speed directly at the hub. Measurement of the rotor speed and position is handled by encoders in the slip ring. For quickly rotating generator shafts Kübler offers hollow shaft encoders with an isolated shaft.How can savings be made with these products, yet at the

An outlook on determining trends in energy and related politics, courtesy of BBC Chartering.In the course of history, energy has always been a driving force for change. Nearly no other industry can claim having a more far-reaching effect on other industry sectors or society at large. The world is continually challenged to find answers to pressing questions surrounding energy supply, energy demand, and sustainability issues in the 21st century. In this article, we present seven megatrends which may continue to determine the energy political agenda in coming decades.Lower priority of ‘climate change' It seems obvious that the discussion regarding climate change has lost its momentum and fallen behind economic priorities. Currently, the top challenges are the global financial crisis, unemployment, and reforming the banking industry. Global leaders are using the term "climate change" less frequently and it seems this trend will continue. Other topics taking precedence are: economic growth, competitiveness, affordability of energy, and the security of energy supplies.This paradigm shift doesn't mean that climate change should disappear from the global agenda. It is part of our daily reality that millions of people, both in developing countries and developed urban areas, often reside under unbearable conditions caused by recurring floods

Regular contributors to PES, Kipp & Zonen are world renowned experts when it comes to providing class-leading instruments for measuring solar radiation. But what is important when it comes to selecting solar irradiance measurements equipment in solar energy projects? And what are the optimal solutions and systems for PV, CPV and CSP projects? We asked the company to provide readers with the definitive answers, including practical information on site prospecting and the efficiency monitoring of solar power plants.There are many questions when it comes to initial site prospecting. Where best to build a solar power plant? Which technology will have the lowest Levelized Cost of Energy (LCOE) and bring maximum return on investment (ROI)? What is the optimal size of the power plant on a given site? Well, knowing the amount and distribution of solar irradiance with low uncertainties will help to answer such questions. The amount of solar radiation available over time under the local environmental conditions is a key input for choosing the optimal location, technology and size of a solar energy project. Meanwhile, feasibility studies and technical due diligence calculations of a solar energy project always start with energy resource assessment.High precision on-site measurements of solar radiation

PES presents an exclusive, in-depth look at the pioneering projects and products of G. Lufft Mess- und Regeltechnik GmbH.Global cooperation with system partners requires a wide variety of different variants and interfaces. Lufft environmental sensors, whether stationary or mobile, can be integrated via many different protocols in new or existing applications.Through the low power consumption, the use of the WS compact weather sensor family from Lufft is altogether possible in the area of solar assessment as well as monitoring. Here, in particular, low installation and assembly efforts are appreciated.But how did Lufft start to evolve sensors for the solar industry?In the early nineties, Lufft used the radiation sensors from Haenni, Switzerland, to build into the first automatic weather stations. The silicon radiation sensor "Solar 130" was the first one to be used for the weather sensors. This specimen served as predecessor of the Lufft-own silicon pyranometer. While in the meantime, Haenni stopped the solar radiation sensor production and Lufft has started to work with Kipp & Zonen sensors - the world's leading pyranometer manufacturer.The weather sensor family has now grown and consists of a wide range of all-in-one solutions suitable for different customer needs. Four of the 18 WS versions

We head to DMG MORI's global headquarters in Winterthur, Switzerland, to discover more about the company's pioneering car charging system and its impact on energy efficiency.It is a widely discussed fact that electric vehicles only drive CO2 neutral when running on green power. Therefore an accessible charging infrastructure based on green energy is essential for the future of e-mobility. The whole infrastructure as shown in the e-charging station register of "goingelectric.de" includes 4,912 charging stations for Germany and 464 for Switzerland (status: 05.08.2015).In the United States the U.S. Department of Energy has registered 10,267 charging stations for electric vehicles. However it is not apparent how many of these stations are supplied by green power. It is striking, at least in the European context, how low the proportion of fast charging stations is. A mere 5% of the stations in Germany and 15% of the stations in Switzerland are listed as fast charging stations.Fast charging means that the charging terminal is capable of charging a vehicle at a rate of 22 kW or more. However, only fast charging stations that are able to provide 44 kW to 50 kW can charge electric vehicles like the VW e-Golf or the BMW i3,
