100 years ago, the world was introduced to the first generation of pyranometers. These thermal hemispherical viewing devices measured the irradiance of the sun on a horizontal surface. Since that first generation, small design changes have been made to improve this state of the art technology. However, all of those changes have been incremental; small changes, yielding small improvements. An entirely new design was needed to make major improvements. EKO Instruments recently made some very big improvements to the pyranometer design. The new MS-80 Secondary Standard (highest class sensor) pyranometer performs at a level never seen before. Using unique detector technology and sensor architecture EKO has pushed the performance in a way no one could have predicted. This single dome sensor is less expensive to produce, when these savings are transferred to the customer, combined with the enhanced performance, the result is the best performing sensor in its class with a low cost of ownership. Why a new detector and with new architecture? While there are silicon photodiode radiometers that respond very quickly to changes in irradiance, the uncertainty in the measurements is rather high. Meteorologists, as well as the photovoltaic (PV) industry, needed a sensor that had a time constant more similar

Quality is ever important in our industry and now Breyer have come up with a high quality, high speed extrusion process which has already been tested by TÜV Rheinland Germany…. BREYER’s extrusion system “CellProtect” allows the production of low shrinkage EVA encapsulation film at high production speed. Most importantly, there is no interlayer film and there is no energy consuming anealing process, which means the production is economic in terms of both cost and energy. Furthermore, Polyolefin encapsulants can be processed using the same method. Encapsulation film produced on regular extrusion lines has a natural shrinkage which affects not only the laminating process but can result in destroyed wafers and therefore creating waste and thus increased production costs. A high quality and low-shrinkage film allows a smooth and fast laminating process. The more shrinkage a film has the more carefully the warm up procedure must be controlled and could increase the laminating time. Since the regular extrusion systems, using calendars or cast rolls, are limited to a certain speed/output, BREYER has developed a profitable system for the production of EVA film and other gluey materials. For the first time, using BEYER CellProtect, it’s possible to extrude EVA or Polyolefine films film at high speed by

Traditional, heavy roof top PV panels can cause damage to both the roof and membrane. Andreas Zimmerer, Managing Director, Soltop EU, introduces PES to a light, quick fit alternative.We, at Soltop, specialise in roof top solutions; our main business is flat roof mounting systems and integrated fall protection systems. Unlike most of our competitors we use a continuous 230 mm wide floor profile. Our focus is to provide the best possible load distribution in order to protect the roof membrane. After all, the most expensive system is always the one that damages the roof!Our systems provide a reliable basis for high-yield generation of solar power. We use the Duraklick mounting system, which is a light, self-supporting flat-roof mounting system for large photovoltaic systems on industrial and commercial buildings. It is a click system and so very simple, very quick and light.Beside our Duraklick mounting system 
for flat roofs, we have the two systems for pitched roofs Duramont and Duravent / Electra. These provide a very aesthetic, roof-integrated solution.The spoiler system is in lightweight aluminium. It was designed especially to meet the requirements of large, on-roof systems. It is of very high quality and can be installed quickly and easily without

Training for any industry is of paramount importance in the drive towards creating an accident free culture and maximum efficiency. It is no less the case with a relatively new industry like wind turbines. Maersk Training is currently bringing techniques and lessons learnt in the oil and gas and maritime sectors to help increase understanding at every level in the wind turbine industry. Training programmes have been developed to involve all staff with a focus on interweaving people skills with technical standards.The same day Orville Wright died of a heart attack, a plane with 31 passengers onboard disappeared without trace in the yet to be labelled ‘Bermuda Triangle.' They were amongst no fewer than 140 people killed in air crashes worldwide that January in 1948.Forty-five years had passed since Orville and his brother Wilbur had broken free of the earth for the first time and in that period the airplane had grown from curiosity to an essential form of transport. What the new industry had yet to learn was how to minimalise the risk factor.It is generally held today that the aviation industry has been the front-runner in the pursuit of an all-embracing safety culture.

In a time when energy companies are coming under increasing pressure to reduce costs, the need for reliable and innovative solutions that focus on improving efficiency and optimising ROI has never been more important.A company fully focused on this core objective is the SeaRoc Group. Formed in 2002, SeaRoc Group has almost 15 years' experience in offshore renewable energy and has been working in the sector since the start of commercialisation. From the outset, SeaRoc Group recognised the need for a user-friendly, integrated system that improves operational safety and efficiency, and helps to reduce project costs. In 2006 the SeaRoc Group went on to develop SeaPlanner, now an industry leading marine management and monitoring tool that does just that.SeaPlanner integrates live data feeds from a wide variety of sources for a complete real-time overview of site operations throughout the lifetime of a project. Developed in-house by SeaRoc Group's team of developers, SeaPlanner is provided as a modular system, giving it the flexibility to be customised to suit the needs of any project scale or phase.SeaPlanner's core modules include Operations Manager for live tracking of personnel, vessels, air traffic and project assets; Personnel Manager for transfer planning, manifest, secure RFID access

More and more we hear about products and systems being developed as a result of client in-put or request. Cagatay Aygar from Vos Prodect Innovations explains to PES that for him experience and know-how are paramount when it comes to innovation. This leads to high quality, cost efficient and easy to use products.Vos Prodect Innovations is an engineering and supply office, located in The Netherlands, with in-house design and engineering capabilities. We are a part of a large Dutch investment group with a primary focus on mechanical and rotating activities.Vos Prodect specialises in the design and delivery of cable protection and cable hang-off systems. We are heavily involved in subsea power and fibre optic cable, offshore wind farm, oil & gas platform and tidal projects. As a result of successful projects we have a reputation for integrity and quality. Innovation, designing easy to use products and cost efficiency are our main aims. For us, innovation means assessing and filtering good technical ideas and combining them with a combination of experience and know-how, converted into custom made systems of interest to the offshore cabling market.
