A 121.2 kW rooftop hybrid solar power plant with a 130.56 kWh energy storage system was installed for the Solli Plus auto centre in Chernihiv.
Alteco provided modelling, design, equipment supply, installation, commissioning and maintenance. The system is designed for self-consumption with energy storage and zero export to the grid.

Project Objective
To install a hybrid solar power plant that would cover the auto centre’s own electricity demand, reduce electricity purchases from the grid and improve the facility’s resilience during outages.
System Configuration:
- 202 JA Solar 600 W modules — 121.2 kW;
- two 50 kW Deye hybrid inverters;
- battery storage — 130.56 kWh;
- ballast mounting system for PV modules;
- zero-export operation.
Roof Load Assessment and Ballast Mounting System
Before implementation, the roof’s load-bearing capacity was assessed. Based on the results, a ballast mounting system for the PV modules was proposed, and the structure was calculated for wind and snow loads.
System Configuration Tailored to the Auto Centre’s Consumption
The solar, inverter and battery components were sized to match the facility’s load profile. The system is designed to use solar energy for the auto centre’s own consumption, with the option to store excess energy in the batteries.
Results
Estimated annual generation is 111,800 kWh, while actual generation is 91,300 kWh.
According to Alteco data, solar generation covers 85% of the facility’s electricity consumption.
The project was completed in summer 2025.
