On-grid plant
No batteries. Power goes straight to the site's consumers and reduces what you buy from the grid. The fastest payback option for factories, shopping centres and warehouses.
Solar power plants and BESS
Uzbekistan gets considerably more sun than Europe, and electricity has become more expensive since 2026. An on-site solar power plant cuts the energy you buy from the grid, while a battery energy storage system (BESS) provides backup during outages and lets you use daytime generation in the evening.
Which plant to choose
Hybrid plant
A hybrid inverter plus batteries. Provides backup power during outages and stores daytime generation for the evening. Suits homes, offices and production sites with critical loads.
Off-grid plant
For sites with no grid connection: remote locations, pumping stations, farms, site cabins. Batteries are a must, and the capacity is sized for the worst days.
A simple rule: if there is a grid and you need no backup, choose an on-grid plant. If you need backup, go hybrid. If there is no grid, go off-grid. Surplus power can be sold to the grid under a contract with the utility; we check the terms for each specific site.
Connection layouts
What a BESS gives you
Backup
When the grid goes down, the load switches to the batteries: within 1–2 seconds in an on-grid layout and with no interruption in a layout with an online UPS. Servers, refrigerators and boilers keep running.
Your own kilowatt-hours in the evening
Surplus daytime solar generation charges the batteries and is used in the evening and at night instead of going to the grid.
Peak shaving
The batteries cover short power peaks such as machine tools, compressors and pumps starting up. You may not need to increase your connected capacity.
Stable voltage
The inverter smooths out voltage dips and fluctuations, so equipment runs within its normal operating range.
Equipment
Solar panels
Monocrystalline and bifacial modules rated 430–630 W with 22–23% efficiency. They retain at least 80% of their output after 25 years.
Inverters
On-grid, hybrid and off-grid, with MPPT controllers. Three-phase units with remote monitoring for businesses.
LFP and LTO batteries
Lithium iron phosphate (LiFePO4): 4,000–6,000 cycles at 80% depth of discharge. Lithium titanate (LTO) batteries work even at −30 °C.
BESS cabinets
Ready-made storage systems from 60 to 215 kWh in a single cabinet, expandable with modules.
Plants built by our group
Since 2020 our group companies have built solar plants in Belarus with a total capacity of about 370 kW, from a hybrid system for a private house to 209 kW on a factory roof.
Sample calculation
A 100 kW on-grid plant on a factory roof. With an estimated yield of 1,500 kWh per kW per year, it produces about 150,000 kWh. If all of it is consumed on site, that is about 147,321,000 UZS a year at a tariff of 982.14 UZS/kWh excluding VAT.
The yield is an indicative figure. For your site we model it hour by hour, taking into account orientation, tilt, shading and your load profile, together with the payback period and the reduction in Scope 2 emissions.
Solar power and Uzbekistan's requirements
On-site renewable generation reduces Scope 2 emissions and is part of corporate energy-saving and decarbonization programmes. For exporters it is also a way to lower the carbon footprint of their products. Learn more in ESG and decarbonization.
How we work
- We analyse the site's consumption from utility bills and the load profile.
- We model generation using an hourly climate model for Tashkent and size the solar plant and BESS capacity.
- We prepare a feasibility study: savings in UZS, payback period, CO₂ reduction.
- We obtain the technical specifications for connection, design the system and get it approved.
- We supply the equipment and install the mounting structures, panels, inverters and batteries.
- We commission the system, connect monitoring and support its operation.
