What we do
enginerji is a marketplace connecting homeowners and businesses in Türkiye who want a solar system installed with registered installation contractors. It does two things at once:
- AI-assisted preliminary design. You mark your roof or land on a map; the system uses PVGIS (EU JRC) satellite irradiance data and the consumption on your electricity bill to work out a suitable system size, an annual output estimate and a payback period.
- Competitive bidding. Your finished design goes to verified contractors in your area, and the bids are compared side by side in one format. Your contact details are shared only once you pick a contractor.
enginerji is not a party to the installation contract signed between customer and contractor. Designs produced on the platform are preliminary estimates; they do not replace an engineer-approved installation project. The final project is prepared by your chosen contractor after a site survey.
