The project involved both upgrading an existing solar installation and expanding the system to meet the site’s growing energy demands. A previously installed solar setup was repowered with modern inverter technology to improve system communication and compatibility with the newly added battery storage solution. This included the integration of multiple inverters, enhancing overall performance and ensuring efficient energy conversion across the site.

Given the nature of the facility, with production spread across different buildings and distances of around 50 meters between key components, system design had to account for communication and infrastructure challenges. These were successfully addressed through a robust configuration that allows seamless interaction between the solar system and the battery storage. The installation was further expanded with additional solar modules, increasing the site’s generation capacity. At the core of the solution is the battery storage system, which captures excess solar energy produced during the day and makes it available for use when needed, including during nighttime or periods of high demand. A key feature of the system is its liquid cooling technology, which maintains optimal operating temperatures, enhances efficiency, and contributes to a longer operational lifespan of the battery.

For Just Paper Tubes, the integration of solar and storage has delivered immediate and long-term benefits. One of the most significant impacts is the reduction in energy costs, as the company can now rely more on self-generated electricity and optimize its usage by storing energy for later use. This is particularly valuable for processes such as drying, where energy demand is both high and continuous. The system also provides greater energy independence, reducing exposure to fluctuating electricity prices and improving overall operational stability. By leveraging stored energy during peak periods or at night, the company can better manage its consumption and avoid unnecessary costs. In addition to financial savings, the project supports the company’s sustainability objectives by lowering its carbon footprint and increasing the share of renewable energy in its operations. The upgraded and expanded infrastructure also ensures that the system is future-ready, with the flexibility to adapt to further energy demands or technological advancements.

The choice of Sungrow was driven by a combination of product quality, advanced technology, and strong support throughout the project. The battery system offered a straightforward installation process, supported by high-quality components and a well-engineered design that simplified deployment on site. Beyond the hardware itself, the availability of technical support played a crucial role. From initial design and planning to commissioning and final handover, both the installer and Sungrow teams provided consistent guidance and expertise. This ensured that challenges related to the site layout and system integration were handled efficiently. Equally important was the collaborative approach between all parties involved. Just Paper Tubes valued the responsiveness and reliability of both the installer and Sungrow, noting that the project felt like a joint effort rather than a standard supplier-customer relationship. This level of partnership, combined with the system’s performance and reliability, made Sungrow the right choice for delivering a solution that meets both operational and sustainability goals.
