One of Sweden’s first hybrid solar parks has been successfully deployed in Halmstad, marking a significant step in the country’s transition to renewable energy. The project, developed by Solarwork Sverige and Powerworks Energy, integrates photovoltaic (PV) technology with advanced energy storage systems (ESS) to enhance grid stability and energy efficiency.
The solar park is expected to generate over 7,000 MWh of clean electricity annually, ensuring a reliable energy supply when demand is highest. Global renewable energy solutions provider Sungrow played a key role in the project, supplying both PV inverters and its PowerTitan 1.0 Energy Storage System.
Meeting Energy Demand with Solar Power
The initiative was driven by the need for cost-effective and on-demand electricity generation. Carl Kuylenstierna, CEO of Sperlingsholms Gods, the plant’s owner, highlighted the importance of solar energy in today’s energy landscape.
“We invested in a solar park because we believe society needs it, and solar energy is a sustainable way to produce electricity,” he said. “We generate electricity exactly when it is needed most—midday—at a low marginal cost.”
The 6.6MWp PV system comprises 11,928 bifacial solar panels, each with a capacity of 550 Wp. These panels are mounted on a ground-based structure and connected through 20 units of Sungrow’s SG250HX string inverters, known for their efficiency and compatibility with bifacial modules.
Energy Storage to Strengthen Grid Stability
To optimise energy efficiency and provide grid frequency regulation, the facility incorporates a 4MW / 4.4 MWh battery storage system using Sungrow’s PowerTitan 1.0. The system operates independently from the PV panels, offering greater flexibility and reliability.
Fredrik Lyckvind, Chief Sales Officer at Powerworks Energy, explained the decision to use Sungrow’s technology:
“We chose Sungrow for both the PV inverters and the battery storage system because they are market leaders and perform exceptionally well in the Nordic climate. The PowerTitan 1.0’s 1C system allows for full charge and discharge within an hour, making it ideal for our market. Additionally, its liquid-cooled technology reduces operating costs and ensures long-term stability.”
Efficient Installation and Advanced Technology
The installation process for Sungrow’s equipment was carried out with precision to meet tight project deadlines. Designed for challenging environments, the company’s technology ensured minimal downtime and a swift commissioning phase.
Fredrik Liljehov, Head of Utility at Solarwork Sverige, noted the project’s significance:
“This is one of Sweden’s first hybrid solar parks, featuring nearly 12,000 solar panels generating 7,000 MWh annually. The 20 SG250HX inverters were chosen for their ability to handle large energy loads while offering flexible installation options.”
Raphael Henkel, Sungrow’s Regional Manager for Sweden and Finland, praised the collaboration:
“This project highlights the growing demand for integrated PV and ESS solutions. At Sungrow, we are committed to providing high-performance technology that supports grid stability and maximises renewable energy deployment.”
As Sweden accelerates its green energy transition, the Halmstad hybrid solar park sets a benchmark for future projects, demonstrating how combining solar power with intelligent storage solutions can create a cleaner and more resilient electricity grid.
