What our clients say
We installed the roofs of five factories in one project. Heliora's structural analysis and permit management saved us from a burden that would have lasted months. Our payback is 4.3 years.
Fikret YalçınChairman, Ankara OIZ Producers' CooperativeThanks to the technical report and production guarantee we presented to the bank, financing was easy. In its first year the plant produced 102% of the planned output.
Hatice YıldızFinance Manager, Bursa Automotive SupplyIn summer, pump electricity was our biggest expense. Thanks to the solar-powered system the bill almost went to zero; the system can also be monitored from the mobile app.
