Battery parks that support the electricity system

The subsidiary Soltech Energy Solutions is a leading player in large-scale energy storage solutions. By developing and installing battery parks, we contribute to a more stable and sustainable electricity system as society becomes electrified. Battery parks store energy from renewable sources and make it possible to use electricity when it is needed most. It reduces the load on the electricity grid, evens out electricity prices and increases the reliability of the energy supply.

One example is the collaboration with Hylte Paper, where the company has installed one of Sweden’s largest battery parks of 42 MWh – complete with smart control, high-voltage equipment and operational solutions.

Charging solutions at the forefront

The electrification of the transport sector is moving fast – and the demands for smart charging infrastructure are increasing. New EU rules from 2025 and increased climate targets mean that both companies and society need to think in new ways.

The solar tech company E-Mobility, develops and installs large-scale charging solutions for electric cars, heavy vehicles and electric boats. One example is our mobile charging station for electric boats, developed for Candela’s electric hydrofoil ferry in Stockholm. It is the first of its kind in the county and shows how we combine technology, sustainability and innovation to create solutions that make a difference.

From roof to solar energy - a complete offer

When the Soltech company Takbyrån in Alingsås was commissioned to help Börjessons Bil with an extensive roof reconstruction of 14,000 sqm, they laid the foundation for something bigger. With strong local roots and long experience in the roofing industry, a relationship was built on trust and quality.

In 2024, Börjessons Bil returned with a new need: a large-scale solar cell plant. Takbyrån’s solar energy department delivered a solution of 2,300 sqm – installed on the roof they themselves previously laid.

This is a clear example of how, by combining our core competence in roofs with the energy solutions of the future, we help our customers take the next step in their energy transition. Result? A property that not only protects – but also produces.

Solar facades are an aesthetic source of energy

Solar facades are a unique overall solution for solar energy and surface layers in one and the same product. With a solar facade as part of the building’s building envelope, it replaces and complements traditional building materials and creates new opportunities for renewable energy production.

Soltech’s facade company’s has installed several solar cell facades, which show how architecture and sustainability ambitions can interact. With integrated solar cells in the facade, the property takes advantage of the sun’s rays, while at the same time getting an aesthetically pleasing exterior.

One example is the subsidiary Fasadsystems’ installed solar cell facade on Campus Borlänge for NCC. The building-integrated solar panels produce solar electricity for the properties and also create an aesthetic impression. Solar facades will play an increasingly important role in line with future EU requirements for solar cells for buildings.

Green energy and biodiversity in interaction

The solar tech company, Soltech Energy Solutions, has installed an 11 MW solar park just outside Falkenberg, which extends over about 14 hectares. The solar park produces green electricity equivalent to the annual consumption of several thousand houses – and at the same time contributes to increased biodiversity.

To promote a sustainable ecosystem, the area is grazed by a flock of sheep, who keep the grass short between the solar panels. The panels, in turn, provide shade for the sheep on hot days. This symbiosis creates favorable conditions for vegetation, insects and pollinators such as bees. The solar park is fenced with a fence covered with ivy.

Sweden's first crisis-ready mobile base station

During the year, the solar tech company Provektor has been a significant installer in the development of Gasum’s biogas plant outside Götene. The plant, which is expected to produce 120 GWh of liquefied biogas (LBG) per year from 2025, mainly uses manure from the local agricultural sector as a raw material. Provektor’s assignments include electrical installation, production of control cabinets, automation and security installations. During the year, work on commissioning, including installation of access control systems and burglar alarms, also continued.

For the Swedish Post and Telecom Authority and Telia, a groundbreaking network infrastructure project N E T has been carried out and created Sweden’s first mobile base station and facility that is ready for crisis and war. A group-wide project, led by sister company Tlab, which installed solar panels and smart control with support from Provektor, which designed and installed automation cabinets.

The Group-wide support function Soltech Business Support also assisted with advice and quality assurance. By combining hydrogen, fuel cells, solar energy and batteries, the Soltech companies’ cutting-edge expertise has contributed to increasing and extending the backup power in the mobile base station from 4 hours to 110 days.
