About us
An engineer who is on-site, not just on paper
Hadži Energy is led by Željko Janković, a civil engineer registered in engineering and technical consulting activities since 10 December 2014. Besides preparing project documentation, he regularly takes on the role of site supervisor — meaning the solutions he designs are also followed through to completion on site, in person.
The focus is on renewable energy: solar power plants and photovoltaic systems, as well as wind farms and wind turbines, together with the supporting electrical and civil engineering documentation.

Client reviews
What people we've worked with say
An example of how this section looks — replace with real client statements before publishing.
The solar plant project for our farm was done quickly, with a clear explanation of every step. We got our permits without a single objection.
MI
Marko IlićIlić Agrar d.o.o.
We needed someone who understood both winemaking and the technical side of solar. The proposal was tailored to our actual consumption, not a generic package.
JP
Jovana PetrovićPetrović Winery
Site supervision was regular, not just a formality. Every change during construction was immediately logged in the documentation.
DS
Dragan StankovićStanković Logistics
As a small business we weren't sure our own power plant would pay off. The feasibility analysis gave us a clear answer before we signed anything.
AN
Ana NikolićEco Hostel Sunčev Breg
Our production plant runs all year, so power stability was our priority. Grid connection went through without disrupting production.
NR
Nenad RistićRistić Dairy
The site study for our wind farm was thorough and honest — it included the risks, not just the potential. That saved us time further down the investment process.

Process
How we work
Four steps from the first idea to a power plant producing electricity.
01
Consultation and site visit
A conversation about your needs, an inspection of the plot or roof, and an assessment of technical feasibility.
02
Concept design and calculation
Sizing the system, estimating energy output and indicative payback period.
03
Main project and permits
Preparing complete technical documentation and obtaining the required approvals.
04
Supervision and commissioning
Following construction on site, grid connection and handover of the finished plant.
Fields of work
Who we design for
Households
Solar systems for own consumption, with or without battery storage.
Business & agriculture
Higher-capacity plants for production facilities, warehouses and farms.
Wind energy investors
Site studies and technical documentation for wind farms and turbines.
