About Us
ENERTRON – A Slovenian Family-Owned Company, a Pioneer in Solar Energy
Clean Energy. Clean Victory.
Gregor Jan, Founder
Ljubljana, 6. februar 2025
At Enertron, we believe that the future lies in clean energy. In 2010, we started with a vision to contribute to a better world through photovoltaics. Today, we are building the largest solar energy projects in Slovenia, but our story is just beginning.
From Humble Beginnings to Industry Leadership
We started with small steps—supplying equipment and refurbishing projects. Today, we deliver turnkey solutions, from small-scale installations to large industrial power plants. With a direct supply network in China and strict quality control, we ensure that every project meets the highest standards of reliability and sustainability.
TRON Group: 13 Power Plants and Innovative Development
Our journey led us to establish TRON Group, which manages 13 of its own solar power plants. We built Slovenia’s largest rooftop solar plant (3.8 MWp at Gorenje) and pioneered projects like Generatron, which combines solar energy with battery storage for greater system stability.
Hisense Europe: A Winning Partnership
With the Hisense Europe project, we proved that long-term collaboration is possible. We built six solar power plants with a total capacity of 4.347 MWp, expected to generate 100 GWh of energy over 25 years. At the end of the contract, ownership of the plant transfers to our partner—this is a clean victory for everyone.
The Future: Beyond the Sun
Our vision goes beyond solar energy. We are developing heat pumps, biogas plants, and wind farms—projects that will ensure Slovenia’s energy independence and sustainability. We believe that every step towards clean energy is also a step towards a clean victory.
Clean Energy. Clean Victory.
This is not just our slogan. It is our promise—a promise to build a future powered by the sun, benefiting us all.
