Hybrid solar power plant with BESS, 500 kW capacity
General information
Hybrid solar plant with battery storage, 500 kW
A 500 kW hybrid solar power plant with battery storage is a solution for large manufacturing plants, agricultural holdings, grain elevators, meat and dairy processing facilities and logistics hubs. A plant of this scale replaces a substantial share of the facility's daytime consumption, while the batteries keep critical processes running during outages and smooth out peak loads.Engineering parameters of the 500 kW plant
- Module array: a 500 kW inverter group is typically paired with an array of ~550 kWp (DC/AC 1.1–1.2). That is roughly 930–950 modules rated 580–590 W (monocrystalline TOPCon, Tier-1 per the BloombergNEF classification).
- Area required: pitched or metal-sheet roof — approximately 3,000–3,300 m²; flat roof with ballasted mounting — 3,900–4,400 m²; ground-mounted rows — around 0.65–0.8 ha.
- Battery capacity: the typical range for 500 kW is 500 to 1,000 kWh (LiFePO4, modular expansion). The configuration is calculated from the consumption profile: backup for critical loads or shifting the evening peak onto your own generation.
- Estimated yield: for southern Ukraine (Odesa region) — about 1,360 kWh per 1 kWp per year with PR 0.80 taken into account; for a ~550 kWp array that is about 750,000 kWh per year, or on average ~2 MWh per day.
- Delivery time: installation works — approximately 8–12 weeks; the full cycle including TU, design and approvals — 5–7 months. The schedule is fixed in the contract.
Indicative cost
The grid-tied part of an industrial solar plant (modules, mounting structures, inverters, cabling, installation) costs approximately 450–650 $/kW depending on the roof or ground type and the equipment class. The battery part is priced separately based on the selected capacity. At 500 kW, an upgrade of the incoming switchgear or a dedicated transformer substation is needed more often than at smaller plants — this is determined by the audit. An exact price is quoted against your single-line diagram and consumption profile.Payback
Payback is calculated individually — based on your tariffs, consumption schedule and plant configuration. We prepare the calculation from your facility's input data.Scope of works
- Consumption audit, analysis of the permitted connection capacity, sizing of the plant and batteries.
- Design, obtaining TU from the distribution system operator, approval of the connection scheme.
- Upgrading the main distribution board, VRP, ShchO panels or KTP substation; if required — a dedicated transformer substation of our own manufacture (plant in Odesa).
- Installation of mounting structures, modules, inverters and batteries; cable routing.
- Commissioning by our own certified electrical testing laboratory, putting into operation, monitoring and dispatch.

Questions & answers
FAQ
What is the minimum investment volume for an industrial solar power plant?
It depends on the plant's capacity and the investment format. Typically, the starting amount is from EUR 100,000 for small projects (1 MW) and higher for large-scale plants.
What is the average return on investment for solar power plants in Ukraine?
Project profitability depends on construction costs, electricity tariffs and grid connection conditions, so it is calculated individually for each project. We provide indicative return figures in a financial model based on your input data.
How much time is needed to build and commission a solar power plant?
The typical project implementation timeline is 5–8 months: from site selection and obtaining permits to commissioning the plant.
What warranties apply to the equipment?
The warranty periods below are set by the equipment manufacturers according to their warranty certificates. LK Energy's warranty covers installation and commissioning works under the contract.
- Solar panels – up to 25 years of manufacturer's performance warranty.
- Inverters – 5–10 years (with an option to extend).
- Monitoring systems and storage units – typically 5–7 years.
How does the investor earn income?
Income is generated from:
- selling electricity on the market (balancing market, bilateral agreements, auctions),
- savings on own consumption (for corporate clients),
- participation in "green" generation programs in the EU (in the future – cross-border PPA).
What risks exist?
The main risks are:
- regulatory changes in the electricity market,
- technical equipment failures,
- weather fluctuations (solar activity).
Is it possible to participate in a project without full financing?
Yes. We work with phased payment against the works schedule. If you are arranging a bank loan or leasing, we prepare the technical part of your application: a technical and commercial proposal, a generation estimate and a cost breakdown. The financing decision and its terms are made by the financial institution.
Is grant or donor support available?
Ukraine periodically has renewable energy support programmes run by international financial institutions and donors. The set of programmes and eligibility terms change, so we check what is currently available for your specific project at the time of enquiry. Support is not guaranteed and is outside our control.
Who handles the operation of the plant after launch?
Under a service agreement we cover the technical side: plant monitoring, scheduled maintenance, and repair or replacement of equipment within the scope and on the terms set out in the agreement. Legal support and accounting remain with the plant owner.
Is it possible to invest remotely?
Yes. All legal procedures can be arranged without the investor's mandatory presence in Ukraine – through a power of attorney and electronic document management.
