Sweden’s first hybrid solar park has been successfully deployed in Halmstad, marking a significant step towards a sustainable energy future. Sungrow, a global leader in renewable energy solutions, played a key role by supplying inverters and an Energy Storage System (ESS). This project, which integrates photovoltaic (PV) technology with advanced ESS, represents major advancements in renewable energy deployment, grid stability, and energy efficiency.
Developed by Solarwork Sverige and Powerworks Energy, the hybrid solar park is designed to generate over 7,000 MWh of clean electricity annually, ensuring optimal energy production and delivery when it’s needed most. Sungrow solutions, played a key role by providing both PV inverters and the PowerTitan 1.0 Energy Storage System, reinforcing the company’s commitment to comprehensive and efficient energy solutions.
A Vision for Sustainable Energy
The driving force behind this ambitious project was the need for cost-effective, on-demand energy generation. “We invested in a solar park because we believe society needs it, and solar energy is an sustainable way to produce electricity,” stated Mr. Carl Kuylenstierna, CEO of Sperlingsholms Gods, the owner of the plant. “We generate electricity exactly when it is needed most, in the middle of the day, and at low marginal cost.”
The 6.6MWp PV installation consists of 11,928 bifacial 550 Wp PV modules mounted on a ground structure. The majority of the solar output is converted by 20 units of the Sungrow SG250HX string inverters, known for their high efficiency and seamless compatibility with bifacial modules.
Energy Storage Enhancing Efficiency and Grid Support
To further optimize energy efficiency and support the grid with frequency regulation, the plant integrates 4MW / 4.4 MWh of battery storage using Sungrow’s PowerTitan 1.0 solution. The system is AC-coupled, ensuring that the PV system and battery energy storage system (BESS) operate independently for enhanced flexibility and reliability. Fredrik Lyckvind, CSO at Powerworks Energy, emphasized the strategic choice of Sungrow’s technology: “We have chosen Sungrow’s technology for both the PV inverters and the BESS system because they are market leaders and work exceptionally well in the Nordic climate. PowerTitan 1.0 was selected for its 1C system, which allows us to charge and discharge in an hour—perfect for the markets we operate in. Additionally, its liquid-cooled technology significantly reduces operating costs and ensures long-term system stability.”
Seamless Installation & Advanced Technology
The installation of Sungrow’s inverters and PowerTitan system was executed with exceptional efficiency, ensuring the project met its stringent timelines. Designed for ease of use and optimized for challenging environments, Sungrow’s solutions minimized downtime and accelerated commissioning. As Mr. Fredrik Liljehov, Head of Utility at Solarwork Sverige, highlighted: “This is one of Sweden’s first hybrid solar parks, featuring nearly 12,000 solar panels that will produce 7,000 MWh annually. We installed 20 SG250HX inverters, chosen for their ability to handle large energy loads while offering flexible installation.”
As the hybrid projects allow the most efficient harvest and utilization of renewables, Raphael Henkel, Regional Manager of Sweden and Finland at Sungrow, remarked on the significance of this project: “We are delighted for our collaboration with Solarwork Sverige and Powerworks Energy. This successful completion of one of Sweden’s first hybrid solar parks highlights the growing demand for integrated PV and ESS solutions. At Sungrow, we are committed to providing innovative, high-performance technology that supports grid stability and maximizes the deployment of renewable energy. This project for Sperlingsholms Gods, is a testament to how hybrid solar and storage solutions can drive the clean energy transition forward and an example of a great partnership between the involved parties.”
As Sweden moves toward a greener energy landscape, the Halmstad hybrid solar park sets a new benchmark for renewable energy projects, showcasing the power of combining solar energy with intelligent storage solutions to create a cleaner and more resilient grid, a concept perfectly aligned with Sungrow’s mission, Clean power for all.
