meteocontrol and Altungrup Solar Enerji team up: comprehensive power plant management for PV system in Antalya
Augsburg/Ankara/Antalya, April 04, 2018 – As a cooperation partner of the Turkish EPC service provider Altungrup Solar Enerji, who is specialized in rooftop solar installations, meteocontrol GmbH has developed the monitoring and control concept for the largest zero-feed-in PV project in Turkey. The 400 kWp rooftop system provides 90 percent of the power needed each day to run the warehouse operated by Reysas REIT in Antalya. The power plant controller made by meteocontrol manages the inverter’s power in response to energy needs: If power production begins to exceed demand, the system is slowed down.
Reysas REIT is committed to solar energy: The leading provider of warehouses and logistics facilities in Turkey has been installing photovoltaic systems on its warehouses for five years now. In the beginning, the company fed the energy generated by the systems into the Turkish power grid. As a result of grid feed-in regulations, the investor has shifted the focus of newly installed PV systems to solely on-site energy consumption. The first and largest zero-feed-in PV system in Turkey was installed on a warehouse in Antalya. The roof unit erected by Altungrup Solar Enerji as a turnkey solution produces 90 percent of the power the Reysas GYT warehouse needs to operate each day.
Power plant controller manages zero feed-in
In its role as project partner, meteocontrol supplied the control and monitoring system. The Augsburg-based PV specialist used its own power plant controller, which meets all PV system grid-connection requirements, to perform the grid feed-in management. To implement the grid operator”s signals, the power plant controller measures relevant values at the grid connection point and passes on relevant commands to the inverters. In larger PV systems, a constant comparison of target and actual yields takes place within a closed loop. This job usually involves managing active and reactive power. “Zero feed-in creates a special challenge,” said Martin Schneider, Managing Director of meteocontrol. “No power may enter the grid – and this is exactly what we’ve accomplished at Reysa REIT. Our power plant controller manages the inverters so they produce only the amount of power the building currently needs.”
Lucrative investment thanks to high on-site energy consumption
The high on-site energy consumption rate of 90 percent has turned the PV system into an attractive investment: It will pay for itself in less than nine years. Power from the grid is needed only when solar irradiance levels are low: in the morning hours and late in the afternoon. “The PV system in Antalya is a successful flagship project,” said Oray Altun, Managing Director of Altungrup Solar Enerji. “It has been reliably producing power for three months now and also covers peaks that occur during the day. Reysa”s power bill is falling, and the investor couldn’t be any happier. “Working together with meteocontrol, we were able to successfully meet the challenges of this project: The PV specialists planned the monitoring and control system and commissioned it on site. meteocontrol”s monitoring portal gives us an optimal solution to keep an eye on the system and watch over it remotely.”
meteocontrol is the leading global provider of independent solar monitoring systems and currently monitors more than 43,000 PV systems with a total power output of over 12 GWp. For more than 40 years, meteocontrol has developed monitoring software and hardware for solar PV systems. They offer planning and commissioning of monitoring systems, as well as yield forecasts, technical due diligence, and energy and weather data analytics. Their independent engineering division has supported projects with a total investment of more than 13 billion euros. meteocontrol GmbH is a member of SFCE Shunfeng International Clean Energy Limited, with headquarters in Augsburg, Germany, and Shanghai, as well as subsidiaries in Lyon, Madrid, Milan, Santiago de Chile, Tokyo, Chicago and San Salvador.
