What does Solar Expert do?
Solar Expert is a subsidiary of ExpertGrup and has been building solar power plants since 2014. With our engineering and technical teams we serve clients in Türkiye and abroad.
See our About page →Which services do you offer?
We work in four main areas:
Commercial rooftop solar — grid-connected plants on factory, warehouse and commercial roofs.
Residential solar — grid-connected systems on house roofs.
Ground-mount solar — for license-exempt generation facilities.
EPC and engineering — feasibility through commissioning, all under one contract.
We also work on EV charging stations, solar irrigation and post-commissioning operations and maintenance.
See all our services →How does the installation process work?
A typical flow: 1) site and roof survey, 2) consumption analysis and feasibility, 3) design, 4) procurement, 5) installation, 6) commissioning.
Duration depends on project size and the application process — we give firm figures for your specific case in the first meeting.What does it cost and how long is the payback?
Cost and payback depend on your consumption, roof area and orientation, and your tariff. A generic figure would be misleading — let us calculate it for your case.
Share your electricity bill and roof details in the form and we can talk specifics in the first call.

Yes — residential solar is one of our services. We install grid-connected systems on house roofs and handle the process from roof orientation and shading assessment through to turnkey installation.
We size the system against your household consumption — share your electricity bill and roof details and we will work it out for you.

Yes — we offer operations and maintenance after installation. Once the plant is commissioned we provide technical support for running and maintaining it.
Scope and terms depend on the type and size of the plant, so let us talk about your specific case.
