India has been witnessing an unprecedented surge in the installation of solar plants since the announcement of the National Solar Mission in 2010. With more than 25GW of installed capacity as on August 2018, the country is chasing the ambitious target of 100 GW Solar PV installations by the year 2022. With increasing installations on land and rooftops, the emerging focus area is to put the untapped vast area of waterbodies to good use. India has 91 major reservoirs with more than 75% of these reservoirs located in the sunny Southern, Western and Central regions. Installation of solar PV plants on water bodies like lakes, man-made and natural reservoirs, industrial ponds and fish farms could be attractive due to the following reasons: 1. The scarcity of large land areas for installation which, in some cases has led to cultivable lands being sacrificed for installation of solar plants. 2. Increasing price trend of land. 3. Optimal use of evacuation infrastructure, e.g.: near hydel projects. 4. Reuse options for abandoned areas like mines, quarries etc. 5. Conservation of water by reduced evaporation. 6. Limiting algae growth through reduced sunlight penetration into water. 7. Improved generation from PV plants due to lower module temperatures. 8. Possible maintenance cost reduction of plants e.g.

The battery market is seeing unprecedented interest and investment. This comes from existing battery manufacturers, vehicle makers, chemical companies, energy suppliers and others, with many businesses moving outside their traditional comfort zones. However, amid all the positive announcements, return on investment has so far been slight. Companies, whether new entrants or existing businesses, face significant risks if they are to successfully carve out market positions. While these risks vary depending on the companies’ positions in the value chain, victorious players will need to manage their way through complex ecosystems, pick the right technologies to back, secure necessary knowledge and intellectual property, and ensure that they can operate at scale in their chosen areas. This must all be done within a traditionally conservative and risk-averse industry. How can this be achieved? One market, many applications When creating a battery strategy, the first point that is vital to understand is that the market is made up of multiple applications, each with different and very specific needs. Factors impacting technology suitability for each application include power density, capacity, cycle lifetime, energy density, capital cost, charging time, reliability and safety. That means, in our view, that no single technology is likely to ultimately dominate the industry

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

Brett Jarman, VP Commercial Business Development at Sunflare spared time to share the company’s vison with PES. Their panels are unique and they are now spending equal time developing commercial and residential solutions. They are super light, can be customized, low on emissions and can be installed in places which were previously thought impossible. PES: Hi Brett, thanks for coming in to talk with us. Could you begin by explaining a little about the background of Sunflare and the importance of the solar/PV industry to you? Brett Jarman: My pleasure. Sunflare has been in development for almost a decade, perfecting the next generation of CIGS technology. Our mission is to reduce CO2 worldwide. For that, solar needs to be installed universally. This is why Sunflare modules are light, thin, flexible and rugged, so they can go everywhere traditional solar is already installed, and many places they can only dream of for the moment. Our SUN2 cells are made of Copper, Indium, Gallium and Selenide on a .127 mm stainless steel substrate. Unlike traditional solar panels, which are covered in glass, our modules are more durable because the SUN2 cells are encapsulated between strong polymer sheets. PES: We have been hearing about your CIGS panels

The price per megawatt used to be the sole decision-making criteria in sustainable energy sources. Now the tide is beginning to turn – the whole energy value chain needs to be taken into account when assessing feasibility. Power purchase agreements are on the rise. Most active are those energy intensive players who see sustainability and a low carbon footprint essential for their future business success. Many of them have an ambitious goal to use renewable energy sources only. You might argue that this is something that is reserved only to the big boys such as Google, Facebook and likes. But be assured, the rest of the business will follow these trailblazers. Call it good corporate citizenship, call it sound business sense. The fact remains the same; there is a growing demand for low carbon footprint energy solutions. For example, Facebook has signed a 294 MW wind power purchasing agreement with Vattenfall. The power for their data centres in the Nordics will come from the Norwegian Bjerkreim wind farm. ‘Bjerkreim wind farm is built on our rock foundations, which will help Facebook to reach their renewable energy goals,’ says Kari Tuominen, the business director for Peikko wind turbine foundations. Google is also a prime example. ‘The 148

Hans-Peter Zimmer, CEO, blade care GmbH and trainer at the blade care Academy, had so much to share last issue that PES felt a follow up interview was necessary. We wanted to find out in more detail about clients’ motivation and some of the specific know-how the Academy offers. Research is also an integral part of improving the services and training offered. PES: Thanks for coming to talk with us again. In our last interview we learned a lot about blade care’s service on rotor blades and the Academy training programmes. We thought it would be interesting to have more details about what types of training the Academy offers and to have more information on your new reporting and management software. To begin with would you like to tell us which the most popular topics in the seminars for administrators? Hans-Peter Zimmer: Clients feel much more confident once they know about the blade structure. The administrators and decision makers need to know the importance of visible and invisible damage. An example is the need to understand the effect of lightning strikes. Some clients are not aware of the fact that plasma arcs can be generated inside the blades. Internal plasma arcs can cause

ZF is a leading pioneer in cost-efficient wind turbines. The reduction of Levelized Cost of Energy (LCoE) is their principal aim. The SHIFT platform concept means it’s now possible to optimize gearboxes for specific-site loads. PES wanted to know more. LCoE of wind energy happens with big evolutions in wind technology. Big is important. There are a couple of ways to produce more power from the wind in a given area. The first is with larger rotors and blades to cover a wider area. That increases the capacity of the turbine, i.e., its total potential production. The second is to situate the blades higher, where the wind blows more steadily. That increases the turbine’s ‘capacity factor,’ i.e., the amount of power it actually produces relative to its total potential. The more variable a source is, the more backup is needed to firm it up and make it reliable. By making wind less variable and more reliable, higher capacity factors reduce backup costs. With increasing capacity factors wind can spread its energy out over a longer period, easing wholesale price pressure during low demand. By extending its hours of operation, a high-capacity-factor turbine is more likely to be producing during demand peaks, when power is
