Company

We didn’t comefor a single project.

For 23 years we have been building a company in the Czech Republic that sells more than technology. We design, build, finance and service energy systems for homes and businesses — and stay with our clients for their entire lifetime.

Where we come from

We started in 2003. Today the BIDLI group brings together real estate, financing, energy and technology. That combination is rare in our industry — and it is why we can take on a project from start to finish.

What we see in South-East Europe

The region has the sun, the demand and new rules for both self-generation and utility-scale parks. What it lacks are companies that take on the whole project and stay after installation. That is exactly what we do.

What we are building

Our own companies in Greece and Romania, an office in Athens and local teams. We are not just a sales office — projects, permits and service are handled by our people in each country.

Bidli Technology enters new markets with the same model: a local company, a local team, the same quality standards and the same know-how from the Czech Republic. For you, that means you are not buying from a single installer, but from a group with a European reach.

Services

Six disciplines. One contractor.

All services on one page

We cover the whole life cycle of an energy project — from the first calculation to repowering fifteen years on. Click a service to read the detail.

How we work

We develop, build and operate.

Three phases, one responsibility. The investor deals with one team from day one to the last year of the asset’s life.

01

Develop

Study, 3D design, yield model, permits and grid connection agreement. A project ready to build or to finance.

02

Build

Turnkey EPC with Tier-1 components, in-house installation crews and site supervision through to successful energisation.

03

Operate

24/7 monitoring, preventive maintenance, repowering. We keep the plant’s yield at its maximum for its whole lifetime.

Intelligent energy management

Hardware is only half of it. We give it a brain.

The Smart A.I. Box links your PV, battery, heat pump and EV charger into one network and decides every fifteen minutes what is most profitable.

  • Buys when electricity is cheapest
  • Sells surplus in the most expensive hours
  • Plans around the weather and yield forecast
  • Cloud app control from anywhere
