A brief summary of our activities

Accredited training center by the Office of Technical Inspection

We have trained more than 1,800 people at SOLSUM Academy. We are accredited to provide training to obtain a Renewable Energy Sources Installer Certificate issued by the Office of Technical Inspection.


We are implementing RES solutions also at SOLSUM

Our company buildings are powered by photovoltaics, a heat pump and an energy storage system. SOLSUM’s company fleet includes 4 100% electric cars, which are charged from a fast charging station at the company’s headquarters during the day and at night. For the most part, the energy that charges the cars comes from photovoltaic installations. Our company building is one of the first office and production buildings in Europe to be powered entirely by renewable energy sources and is additionally completely energy independent thanks to system energy storage.

Our internal company communications are completely paperless and also without a printer. Notes that are necessary for project work, as well as contractor data, reports and statements are in electronic form. As well as proforma invoices, audit reports, product statements, development plans are created without the use of paper, which makes ecology go hand in hand with economy.

A zero-carbon economy is a bold vision, but even the farthest journey begins with the first step.

Feel free to contact us – we will help implement RES solutions in your company.
