Our own installation company

We know our products not just from technical descriptions, but from real-world experience. Our installation company, Green Technology, builds solar power plants in the Odesa region, giving us a deep understanding of how equipment performs under actual conditions. This allows us to select and offer solutions whose reliability and effectiveness we are confident in.

32 kW solar station at a gas station in Chernomorsk.

The business now significantly reduces its electricity costs. Sunerise brand solar panels, rated at 450W and 585W, were installed. A 50 kW inverter and a 50 kWh battery from Deye were also installed.

9 kW Solar Energy System for a private house

The client wanted to eliminate electricity bills entirely, but there wasn't enough space on the house roof for all the panels. We found a solution: we designed and installed a special metal structure, enabling the owner to become completely energy independent!

9 kW station in a private house

The owner wants complete autonomy, so a 9 kW solar station was required. We installed 450W panels, an 11kW inverter, and two 15kW lithium-iron-phosphate batteries each.

Private house: 12 kW solar station

Now the client's home is fully equipped with its own electricity and does not depend on external suppliers. Another step towards an energy independent Ukraine!
