Pilot project for a fossil free and electrified vegetation maintenance in solar parks receives government funding

Husqvarna, Alight and SLU (Swedish University of Agricultural Sciences) have joint forces on a pilot project that aims to develop and validate autonomous electrified cutting of vegetation in a solar parks utility scale in attempt to remove fossil fuels from solar park maintenance. The project, which is the first of its kind, has received over 4 million SEK in funding from Vinnova (Sweden’s Innovation Agency).

Green innovation to remove fossil fuels and in the long run completely switch to the use of renewable energy, is in growing demand. Large solar parks have a potential to be fully fossil free, but they need to be managed by cutting the vegetation to avoid shading the panels, which results in production falls, and to avoid that woody vegetation damages the solar panels. Those mowers and machines are currently generally powered by diesel, but could now be replaced by new technology.

This project is the first of its kind within fossil free mobile work machines deployed in solar parks and will stretch through August 2020 – December 2022. The project consists of knowledge building, implementation, execution and evaluation, and is now in the first phase. The implementation of the autonomous mower in the solar park will happen in the spring 2022. Researchers at SLU will collect data on site during the whole trial period to generate new knowledge about how it can create added value in the form of biodiversity.

Harald Överholm, CEO of Alight, says “For a sustainable and fossil free future we need not only a rapid transition to and addition of new renewable energy, but also that the industry applies tech innovations to replace work machines run on fossil fuels with electrified machines. I am very proud to set bold ambitions for green innovation by testing new solutions in partnerships with industry leaders like Husqvarna and having researchers from the Swedish University of Agricultural Sciences evaluating and qualifying the results. The solar energy industry is growing rapidly and we hope the results can be applied across the industry to optimize the management of solar parks from both an economic and environmental point of view”.

Glen Instone, President Husqvarna Division, says “We are excited to participate in this pilot, as it is very much in line with our own ambitions for the coming years – to help our customers make more sustainable choices by offering a broader range of products that are electric, smart and autonomous. This will require a lot of investments into new product development from our side, and this pilot offers an excellent opportunity to take a leap in the right direction. We are excited to test some of our latest innovations in the field next year, together with such knowledgeable partners as Alight and SLU”.

Tobias Emilsson, researcher at SLU, says “Within this project we are developing new knowledge in an exciting rapidly growing field together with leading industry partners. We will likely see a continued expansion of solar parks in Sweden and it is therefore important to find ways to manage vegetation at a reasonable cost at the same time as achieving high energy production and sustained ecosystem service provision such as e.g. biodiversity”.
