More and more home owners are installing PV systems. How efficient are these systems? What does the industry need to do to support this growth area? PES takes a look at Huawei’s new, flexible solution. Across solar markets globally, we are continuing to witness the maturation of utility scale solar, with subsidy-free commercial projects increasing in frequency. As solar’s share in global energy generation continues to rise exponentially, the industry’s ability to innovate expands too. The rapid technological developments and cost reductions that have been driven by investment in utility scale are also having a positive influence on the growth of the residential sector. From an industry perspective, this growth has been accompanied by a proliferation of residential PV systems and technologies now available to installers and homeowners. So with residential solar now set for another significant period of expansion, it is essential that PV technology developers are able to offer systems that can handle the huge variety of customer demands across what is an increasingly competitive and crowded marketplace. The growth of residential Previously, residential solar was supported by necessary financial incentives in order to prove attractive to homeowners. As we look at the costs of a typical residential PV system in some

Electroluminescence (EL) imaging, as a versatile tool for spatially resolved defect analysis on Si-solar cells, has recently gained a lot of traction in its industrial application. In this article we discuss quality control and process control abilities of this technology and how it is applied in solar cell production. We demonstrate how an IV tester-integrated solution is ideally suited to increase quality and yield and correlate the EL-data easily with IV results. Quality requirements for solar cells are constantly rising. Besides the current-voltage (IV) measurement as sole end of line quality control tool so far, it becomes necessary to detect deficiencies which do not significantly affect the IV measurement, such as e.g. cracks. The minority charge carrier concentration can be converted into the junction voltage [3], which is either governed by the above mentioned recombination processes or by series resistance between the current terminals and the position at which radiation is emitted. The spatially resolved intensity of light emission is captured by a CCD or CMOS camera, resulting in images in which defects appear as darker regions. Therefore, EL imaging is capable of visualising all defects induced by recombination as well as series or parallel resistance. Whereas, a lot of scientific work

With ample desert space and swathes of sunshine all year round, the solar power industry is starting to heat up in the countries of the Gulf Coorporation Council (GCC). Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates are all well placed to benefit from technology advancements and lowering costs. Over the past few years, the UAE has launched some major solar projects, while Saudi Arabia announced the largest-ever project in March this year. The GCC’s increase of solar generation capacity is well timed. The global renewable energy industry is experiencing considerable growth, supported by governments and policymakers’ efforts to combat climate change, a steady decline in renewable generation costs over the past decade, and continued technological developments. As such, we expect that most GCC countries will continue to invest in solar efforts in the years to come. Lower costs, higher investment Renewable power installation costs have been declining sharply over the past decade, driven by technological improvements and the associated increased efficiencies. In turn, these developments are making renewable energy a viable alternative to traditional carbon-based electricity generation. The considerable growth in the global renewables sector as a result is encouraging. According to the International Energy Agency (IEA), renewables represented two-thirds

The price of photovoltaic (PV) systems continues to decrease, adding PV as a cost effective cleaner energy solution. While solar photovoltaic grid penetration increases worldwide, new technical challenges arises in the electric grid side. Little progress has been made to incorporate managing schemes in solar power systems to improve the utility management. PV growth, its drivers and implications to the grid However, many technological solutions have been presented to facilitate the grid side. For example, using bifacial PV modules setup vertically to shift the electric energy generation peaks to match the peak of electricity demand are currently under study and are now becoming attractive due to cost effectiveness of PV. Developments in electronic house hold appliances now also offer the possibility of connecting a device to the internet and communicate with the grid, realizing the concept of Smart Grids, in which interconnectivity and live data sharing between both the devices producing and consuming electricity allow a better understanding of demand and supply of electricity. Additionally, the storage systems, one of the missing links to the efficient solar power integration, are following the same trend as PV in terms of cost reduction, opening new possibilities for managing the energy sector. Managing the energy flow from

Industrial exhaust gas purification is a vast area. There are many different technologies and facilities for the effective treatment of pollutant emissions. This is primarily due to the high heterogeneity of exhaust gases from different industrial processes. PES delves deeper. Depending on the application, the composition of the exhaust gas can vary greatly from process stage to process stage. The modular system allows individual adaptation to the specific process application. This poses a challenge for conventional systems for exhaust gas purification, as individual exhaust gas purification technologies are often pushed to their limits for variable gas compositions. centrotherm clean solutions GmbH & Co. KG has therefore developed a modular system for cleaning exhaust gas. The modular system combines different cleaning technologies put together depending on requirements. Cleaning systems for thermal or wet-chemical treatment as well as dry bed absorbers can be combined with each other according to customer specifications. At the same time, intelligent communication of the system modules guarantees safe and cost-optimised operation at all times. ‘In order to find the best possible exhaust gas purification solution for an industrial application, the various factors of an application must be carefully considered,’ explains Thomas Kraus, Sales Manager Europe at centrotherm clean solutions GmbH &
