Our vision

Our vision

We are passionate about innovation, quality and customer service. Together with our clients, our people, and our partners we want to make a noticeable difference in providing the world with clean and renewable energy through widespread adoption of solar power. We are here due to a genuine desire to transform the world – not just to make a quick profit.

Clean solar energy

Clean solar energy

We offer a high-quality service and we are committed to make solar energy work for you – from the no-obligation site survey through design to installation and beyond; we take care of everything. Give us an opportunity and we will guide you through the entire process up to the production of clean solar energy.



We understand the diverse and complex nature of PV solar installation projects. Whether it’s developing design solutions for rare roof structures, dealing with problematic engineering matters or helping you settle planning and logistics issues. We have the experience and skills that your project needs.



We don’t just engineer and install the PV solar technology for the present moment. Solar energy plants which we provide will power your property for twenty years or more without any output losses. To guarantee such an economical work of the solar plants, it is necessary to maintain and to service the whole PV solar system. We also offer this service separately.

02 What we do?

At Ecotec, we are passionate about renewable energy and the condition of our environment. We are convinced that renewable energy and energy efficiency have a huge role to play in helping the world reduce its dependence on fossil fuels and their impact on the environment.

Since the sun is an incredible source of energy, our mission is to increase the adoption of solar power and allow otherwise useless surfaces to be used to harness the energy of the sun and convert it directly into electricity without any noise or carbon emissions.

Our commitment to making solar energy accessible is abiding and inexhaustible, and our firmly settled business is in the steady growth process. We feel that the world has some enormous challenges ahead of it - from climate change to the resource exhaustion and the potential economic problems that will follow. With solar energy, solar farms and solar parks, people take the course to be independent of raw materials. The use of solar energy strengthens independence in terms of the scarcity of fossil materials and price increases. Therefore, as a company that is founded on environmental objectives, we consider solar farms as an ecological and economical necessity.
