Film increases module power by 1.5-2.0 percent PAUL, Minn. – September 19, 2018 – As the solar energy industry continues to grow at an exponential pace, increased focus has been given to maximizing the performance of all solar module components. Specifically, efficiency improvement has become a critical driver to reduce cost per watt and increase annual energy production (AEP). Although advancements in solar cell technologies have been rapidly adopted by the industry, better managing incoming sunlight provides another supplemental avenue to improve module efficiency. Following a successful launch in late 2016, 3M is releasing a technical paper highlighting the science behind 3M™ Light Redirecting Film (LRF) and why the 20 GW of solar modules already deployed are expected to show performance gain from 3M LRF over the long-term. In a typical solar module, up to 15 percent of the area is non-active, meaning incident light falling on those parts of the module is not being converted to electricity. 3M Light Redirecting Film is applied over the tabbing ribbon during the cell stringing process. The film’s sophisticated optical structure design helps improve the module’s maximum power and annualized energy gain, regardless of the orientation of the module once it’s installed. By utilizing

Solution Offers Flexible Integration with New and Existing PV Systems ROCKLIN, Calif.—September 19, 2018—As the cost of solar-plus-storage continues to drop, many utilities are turning to PV instead of traditional power plants. To meet the market’s demand, SMA has introduced a new DC coupled storage solution ideal for utility-scale PV projects, and is now taking orders. The new DC coupled storage solution is built for new PV plants, but it can also be used to retrofit existing PV plants for those operators who want to enjoy the benefits of solar-plus-storage. In many utility-scale applications, DC coupling can offer significant operating cost and efficiency advantages over AC coupled systems. “With more than 60 gigawatts of solar and one gigawatt of storage inverter capacity installed, SMA understands the value of the two core technologies. Building on that expertise, SMA has unique competence for pairing PV and batteries,” said Boris Wolff, Executive Vice President for SMA’s Utility Business Unit. “Building a PV plant with storage, or adding storage to an existing PV plant, enables new business cases. Utilities will find many additional benefits when adding storage to their PV systems.” The DC coupled storage solution consists of SMA’s Sunny Central EV-US line of inverters with a DC coupling ready

New SmarTrackTM optimization technology delivers major returns to utility-scale solar projects ALBUQUERQUE, New Mexico (September 19, 2018) – Array Technologies, pioneers of solar tracking technology, announced the release of its latest innovation today. SmarTrackTM is an optimization technology that intelligently adjusts module angles in response to weather and site conditions. The new software, in combination with DuraTrack®HZ v3 solar trackers, will optimize backtracking power production on as-built project conditions to capture the maximum power yields during diffuse light conditions.  “The next generation of solar tracking has arrived. We have created a suite of software which consists of three separate machine-learning algorithms, all of which are fine-tuned to maximize power output in different scenarios,” said Jim Fusaro, chief executive officer of Array Technologies, “SmarTrack is a testament to Array Technologies’ commitment to providing our customers with the highest yields in both energy production and financial returns.”  The software suite utilizes self-learning algorithms that work independently of each other to optimize the energy output of the PV system. Once an operational strategy has been learned, the tracker system orientates PV modules to the optimal angle for power output responding to specific module technology, weather and site conditions. SmarTrack offers three distinct optimization algorithms designed to provide optimum power production Backtracking: Undulating

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

Today is the kick-off for what is becoming the largest solar park in Sweden. The plant is located near Säve airport and is part of a major investment in solar energy, made by the Swedish utility Göteborg Energi. The solar park in Säve, outside Gothenburg, will be the largest so far in Sweden covering 11-hectares, a little less than 16 football fields, with a capacity of 5.5 MW. It is expected to generate approximately 5,000 kWh of electricity a year, enough to satisfy the yearly electricity needs of 1,100 households. "With our investment we increase the production of renewable electricity and take another step towards a renewable energy system. We have always had great experience and relations with ABB and so it felt quite natural to include them in this journey,” says Alf Engqvist, Managing Director at Göteborg Energi. ABB is delivering a substation with switchgear, distribution transformers and relays, together with control equipment and inverters.
