Panel soiling has been a running concern for solar park owners since the birth of the solar/PV industry. With many parks located in dry soiling environments, dirt accumulating on solar panels can be a major drain on efficiency, limiting power output and driving up cleaning and maintenance costs. DSM’s new Anti-Soiling coating offers a compelling answer to this widespread industry problem. Powering up output, panel by panel A multidisciplinary team of scientists and application technologists from DSM spent three years developing the Anti-Soiling coating solution before it was ready to be brought to market. The coating is an offspring of the company’s patented Anti-Reflective (AR) coating, which has been available on the market for seven years and is now in use at more than 50GW of installations globally. A series of indoor and outdoor validation tests were carried out as part of the R&D process. These included a controlled, climate-representative test, which was undertaken at a TÜV SÜD solar park in the Gobi Desert, in Dunhuang, China. During the assessment, modules coated with DSM’s Anti-Soiling coating were benchmarked against panels coated with DSM’s Anti-Reflective (AR) coating, as well as non-coated modules, over an 18-month period. During this time, the DSM team spent 12 months

Data can be our crystal ball. With advanced analytical tools, we can harness the flow of data from turbines, solar cells, dams, our organisations and even external sources, such as energy markets, to optimize performance and earnings. You can look into the future, now. Businesses thrive on predictability. Stable demand, stable supply, stable operations and, if we’re doing it right, stable growth and positive development that leaves us, and all our stakeholders, with stable smiles on our faces. However, renewables are unpredictable. The supply of energy we convert is inherently unstable – it fluctuates according to the whims and fancies of a power beyond our control, that of Mother Nature. Hydropower is perhaps the exception, as dams offer operators a steady means of power storage and production. All we have to do is, quite literally, turn on the tap. Nevertheless, unpredictable weather patterns, such as prolonged dry periods, can impact upon even this most proven and reliable of renewable sources. So, how do we bring predictability into this new energy arena? We can’t tame Mother Nature, but we can learn from her, from ourselves, from our equipment, and from the energy market to continually adapt and optimize our assets and operations. In doing

Some years ago, the offshore wind industry was primarily a high-priced and tough European adventure. But, mainly as a consequence of intense private-public collaborations in the key countries nearby Irish, North and Baltic seas, this situation has dramatically changed. Nowadays, the offshore industry is widely recognized as a key component for the future generation mix, proudly showing a flourishing market with a new range of turbines, well-built supply chain and continuously optimized costs. As a result of this recent market progress, other countries beyond Europe have focused on offshore solutions too, arranging plans for gross spread of this industry mainly in North America and Asia. As an example, more than 1GW of offshore was installed in China during 2017 and determined programs for offshore expansion, have recently been set in the US for the next decade. The Indian government has recognized that both the demand for electricity and the need to decarbonize is going to rise steadily and so has defined forceful objectives for 2022. Thus, offshore wind is set to become a relevant sector in the medium and longer-term plans. The areas of Gujarat and Tamil Nadu have already been identified, as places where strong and steady resources of clean energy, can be

Amid yet more uncertainty in the solar industry – fuelled by the recent policy shakeup in China and subsequent plunge in PV module prices – leading manufacturers know that the best course of action is taken with a steady hand and eyes fixed firmly on the horizon; a horizon shaped by PV innovation and quality. Right around the time that the world’s largest solar power exhibition, the SNEC show in Shanghai, was winding down at the end of May, Chinese officials were silently preparing to drop a bombshell that was soon sending shockwaves throughout the PV world. The country’s National Energy Administration (NEA), the National Development and Reform Commission (NDRC) and the Ministry of Finance had prepared a new policy that stated, in no uncertain terms, that the government would not approve any more subsidized large-scale PV projects for the remainder of the year, effective June 1. The government bodies also confirmed a cut in the feed-in tariff (FIT), placed a cumulative annual cap on distributed generation (DG) installations at 10 GW (previously 19 GW) for the year, and introduced a new auction mandate for utility-scale projects. There was a lot to unwrap in this new policy. The kneejerk response among many solar

There have been solar cells based on semiconductor technology since the middle of the 20th century, and photovoltaics (PV) have undergone continuous development since that time. Trends have always played a decisive role in the development of PV. An important trend is characterised by technology, market, materials and investors coming together at an opportune moment. Megatrends are indicative of especially strong changes that have a major impact on the development of technology and the market. Developments in photovoltaics Bell Labs made the first n-type silicon solar cell to generate electrical energy directly from sunlight as long ago as 1954. At that time, the semiconductor industry was in the very early stages of its development and material prices were still very high. After 1970, the semiconductor industry evolved rapidly, as a result of which suitable semiconductors became available. The first commercial solar cells were produced mainly using scrap wafers originating from the manufacture of integrated circuits. At the same time, research efforts were initiated with the goal of improving solar cell efficiency. The solar cell structures in use today were devised and first developed in the laboratory in a relatively short period of time. In some cases, however, it would take more than

Infrastructure is not a short-term investment. Once installed, these critical systems have to remain useful for at least 20 years. Public utilities looking to invest in solar power and other renewable energy systems face pressure to ensure that these systems are cost-effective and meet the energy demand. As the cost of solar power has come down considerably, and more public utilities seek to incorporate it into their energy mix, infrastructure is where we will see the next phase of technological development. For investors, this presents a powerful opportunity to back the solutions that will transform the energy industry over the next decade. The next phase of investment In reality, energy generation only accounts for 35 percent of a utility’s costs, be that from solar power, wind power or natural gas. The bulk of utility costs come from operating and maintaining the underlying distribution infrastructure. Even the most efficient energy generation methods will result in excessive costs if the distribution infrastructure fails or functions incorrectly. For newer systems to be installed effectively on a large-scale, it is not enough to simply shoehorn them into old structures. The state of solar power today demonstrates this phenomenon. As it stands, solar photovoltaic (PV) hardware is more affordable

Backsheets are the important components of a solar PV panel. It is essential that they are of high quality to avoid degradation, unnecessary maintenance, and replacements, which all add to the costs and in turn decrease the user’s profit margin. PES gets the latest from Bischof + Klein on their new generation backsheets using their improved manufacturing process. History of Bischof + Klein In 1922, the company entered the packaging industry with the production of paper sacks for the neighbouring lime and cement works. Small paper packaging items and newspaper printing extended the product range. 1950 saw an increase in the production of consumer packaging. At the beginning of the 60s, B+K was amongst the pioneers in plastic processing, and has been producing industrial packaging manufactured from plastic since 1963. From 1980 onwards, the consumer packaging range was extended with the expansion of plastic processing. This period also saw the establishment of a new division: Technical Films. Focus in the Technical Films division is placed on the production of surface protection films, technical laminates, films for lamination and backsheets. The B+K-GROUP manufactures its products using state-of-the art systems for mono/co-extrusion, gravure/HD-flexographic printing, solvent-based/solvent-free lamination and coating plus for extrusion lamination and coating.
