Passivated emitter and rear contact (PERC) cells, currently regarded as being the most economical solar cell design, can now be individually inspected with the highest contrast. A new inspection system meets the challenge of inspecting the cell’s rear side. With its exclusive multi-channel and multi-image technologies, it merges high contrast image parts for a […]
Would the average consumer invest in the stock market without real-time insight into financial performance? Not a chance. We live in a world that craves information, preferably easily accessible and digestible information, especially when it pertains to a major financial decision. Why should PV installations be any different? Commercial photovoltaic (PV) projects are increasingly […]

The ever-accelerating development of increasingly larger wind turbines creates new challenges: more intelligent systems with additional sensors and actuators are used, further increasing the complexity of the systems. This makes fault analysis much more complex and stable operation increasingly difficult. To address these challenges, existing concepts and technologies were combined, resulting in the development […]
The position and elevation of the sun in the sky changes throughout the day and this affects the output of solar panels. Large scale solar PV installations use tracking of the suns elevation and/or azimuth as maximise output over the solar day. Trackers can be of simple or complex design, and different types of […]
Photovoltaic (PV) systems offer a number of benefits, from financial savings to environmental advantages and energy independence. As these benefits are driving PV systems to be installed around the world, the industry has gained a better knowledge of the needs for PV systems’ safety. In general, PV systems are safe, reliable, and do not […]
Concerns over the effects of carbon dioxide (CO2) emissions on climate have led to programmes aimed at reducing of CO2 emissions, primarily in the power generation and transport sectors. Coal fired power stations will still be in use for many years, and research has been focussed on capturing and sequestrating CO2 from coal sources. […]
Many commercial Concentrated Solar Power (CSP) plants are operating in various places around the world, the technological development of storage capacity is advancing with each new CSP plant that comes online. The 50 MW Bokpoort CSP plant is capable of storing more than nine hours of thermal energy. At its recent inauguration, EE Publishers […]
The price of solar panels has dropped to the point where many customers find it cost effective to install them on their roofs, reducing their monthly electric bills in the process. The value proposition is greatly enhanced if the distribution company offers a credit for any net or excess generation fed into the grid. […]
Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear. Researchers from the Technical University of Munich (TUM) have now managed to observe these processes in real time. […]
