The recently ended year 2019 was a bright year for solar business as a whole and for Gantner in particular. Gantner is very excited about having commissioned monitoring and control solutions for another 1 GW solar power in 2019.

Gantner’s complete monitor solution has been supplied for example in projects in Australia, Denmark, Germany, Greece, Hungary, Indonesia, Jordan as well as in the Netherlands and Spain. A new market Gantner entered is Ukraine which strengthens the company’s portfolio in Eastern Europe where already some of the region’s biggest solar power plants in Belarus and in Kazakhstan work with Gantner’s system.

In 2019 the total number of newly acquired measurement channels with a typical measure rate of up to 1 Hz sums up to about one million. On top of that another five million of calculated channels are imported into cloud-based Gantner’s webportal with a market-leading storage rate of one per minute. The huge amount of collected data provides the opportunity to apply new big data technologies to gain valuable information about the state of a power plant, to calculate production forecasts and to perform predictive maintenance. With Gantner’s “Mechanistic Performance Model” it is possible to compare the actual outcome of a PV plant with target values based on the structure of the plant and on weather conditions.

The goal for 2020 is to use the high momentum of the PV industry to strengthen its position as an international market leader with monitoring and control of solar power plants “Made in Germany”.

Following last year’s announced cooperation with Tigo, GoodWe is now launching the DNS and SDT rapid shutdown inverter series with MLPE functionalities, a streamlined solution for the optimization of energy yields on the module level which is perfectly adequate for complex system designs and partial shadings – using optimizers on shaded modules recovers an average of 36% energy loss due to mismatch.

Offering from shutdown code compliance to module-level diagnostics and maximized energy harvest, the Tigo TS4 platform works seamlessly with both GoodWe DNS and SDT inverters. Compared to other traditional optimization systems in the market which require MLPEs on every module even when it is not necessary, GoodWe offers a highly efficient solution with fewer BOS components which lowers the overall cost of the system and is easier to install.

The TS4 platform utilizes two key components that are compatible with any PV module: a base that is integrated into the module, and five separate detachable covers housing varied levels of MLPE functionalities. Customers can mix and match TS4 covers according to their ideal budget and system requirements. The TS4 platform offers the option to selectively deploy the exact functionality needed to maximize system performance, all while guaranteeing the lowest cost with the greatest ROI. The retrofitting process can be completed quickly just with changeable solar junction box covers which do not require any screws, allowing easy upgrading or fast replacement in case of damage. Furthermore, thanks to the integration of Tigo’s Cloud Connect Advanced (CCA) datalogger, users can reduce hardware costs avoiding the need to purchase an additional datalogger. Fewer components reduce potential points of failure and risk, and simplifies service when it is required.

GoodWe DNS and SDT series smart inverters can offer a cost effective and reliable solution that matches perfectly with smart modules. This enables end users to harness more system data for valuable insights about real-time analysis in both Tigo and GoodWe’s monitoring platforms and also enables cost-effective datalogging to collect operating information from the inverters as well as each smart module.

“With the launch of these smart inverters, integrators can benefit from reduced installation time, service risk, and ultimately cost,” said Huang Min, CEO of GoodWe. “GoodWe DNS and SDT series with MLPE functionalities offer customers a flexible solution which realizes greater energy production and roof usage, while providing a higher ROI.”

The Siemens Building Technologies Division has won the 2015 European Energy Service Award (EESA) in the Projects category for its implementation of an Energy Performance Contracting (EPC) project in the Polish city of Sosnowiec. This project focused on the heating systems and energy management in 87 public schools and preschools in this industrial city in the Silesia region. All heating and lighting systems in the buildings were modernized from the ground up in a period of just ten months. In addition, the Advantage Navigator energy monitoring system was installed to remotely monitor overall energy consumption.

The system allows personnel to remotely control the room temperature in every classroom and set it to the desired target value. “In the past, classrooms were typically kept too hot, which made it difficult for students to concentrate. Thanks to the state-of-the-art heating system and continuous energy monitoring we are now able to provide a comfortable learning environment for students,” says Marek Tobiacelli of Siemens Poland.

At the same time, Siemens has guaranteed heating cost savings of approximately 31 percent, electricity savings for lighting of 21 percent and a reduction of CO2 emissions by 5,220 t/year compared to the initial situation. The measures are financed through an Energy Performance Contract with Siemens. This means that the city of Sosnowiec’s initial investments of approximately 4 million euros will be paid back through the guaranteed savings realized over the ten-year contract period; interim financing is provided by Siemens.

The impressive energy and cost savings for the city as well the positive impact on the environment are a big win in and of themselves. However, the results achieved also benefit students and teachers who are now able to learn and work in classrooms offering a comfortable temperature – and hence a healthier environment.

The European Energy Service Award (EESA) is part of the European Energy Service Initiative toward the EU 2020 Energy Saving Targets (EESI 2020). This initiative aims at fostering the use of Energy Performance Contracting in Europe. The EESA honors outstanding efforts and achievements in the field of energy services in Europe. This year’s award ceremony will be held in Brussels.
