How much does a 5 kW and 10 kW solar power plant cost in 2026: prices and turnkey installation
Today, owning your own solar power plant (SPP) is no longer just an environmental trend, but a vital necessity for Ukrainian families. Regular power outages and rising tariffs force owners of private homes to look for autonomous solutions.
The most popular for the private sector are hybrid systems based on 5 kW and 10 kW. They allow you to not only use free solar energy during the day, but also store it in powerful batteries in case of a blackout.
In this article, we will analyze in detail how much the equipment included in it costs using the example of a modern kit with a LiFePO4 battery, and how to independently calculate the full cost of a turnkey system.
1. How much does equipment for a 5 kW solar power plant cost?
To understand the price range, let's take as a basis a real professional kit - Hybrid sunny 5 kW power plant with LiFePO4 battery.
The retail price of such a ready-made set of equipment is 100 585.00 UAH (or approximately $2 241 at the current exchange rate).
What is included in the price of the 5 kW kit?
This is a balanced technical solution, where every detail is selected for maximum efficiency:
| Component name | Number | Price per piece. | Total |
|---|---|---|---|
| Hybrid inverter Sako Sunon Pro 5.5 kW | 1 pc. | $600 | $600 |
| LiFePO4 battery Enersun-WM-100 (51.2V 100Ah) | 1 pc. | $858 | $858 |
| Premium solar panels (Axioma 585W / Risen 590W) | 8-9 pcs. | ~$87 | $783 |
| TOTAL EQUIPMENT: | $2 241 (100,585 UAH) |
Technical advantages of this kit:
- The reliable heart of the system: Inverter Sako Sunon Pro at 5.5 kW withstands peak loads up to 11000 VA and has a built-in high-efficiency MPPT controller at 100A (efficiency 98%). It can work even without batteries, simply transforming sunlight into household electricity.
- Long-lasting battery: Battery Enersun-WM-100 with a capacity of 5.12 kWh is built on lithium iron phosphate (LiFePO4) technology. It has a resource over 6000 cycles charge-discharge, which provides about 15 years of daily operation. Safety is controlled by the built-in BMS system.
- Powerful generation: Monocrystalline solar panels (N-type, half-cell, 16 MBB bus technology) have an efficiency of over 22.6% and generate energy perfectly even in low or diffuse lighting (in cloudy weather). Their service life is over 30 years.
What can a 5 kW solar power plant provide? This is enough to fully power the critical appliances in the house: refrigerator, lighting, internet router, TV, water pump, computers, and occasional use of the washing machine or boiler during daytime hours.
2. How much does equipment for a 10 kW solar power plant cost?
If your house has an area of more than 120-150 sq m, and among the consumers there are powerful air conditioners, an electric stove, a heated floor or an electric boiler, a 5 kW system may not be enough. In this case, choose 10 kW station.
For a 10 kW station, most system parameters are doubled:
- Inverter: A more powerful hybrid inverter of 10-11 kW is needed (or two 5 kW inverters operating in parallel). Price: ~$1 100 – $1 400.
- Batteries: For a 10 kW system, it is desirable to have a larger energy reserve - at least two LiFePO4 blocks of 5.12 kWh each (total 10.24 kWh). Price of two batteries: ~$1 716.
- Solar panels: The number increases to 16–18 pcs. (with a total capacity of about 10-10.5 kW). Price of the array of panels: ~$1 400 – $1 600.
Approximate cost of a 10 kW equipment set: $4 200 – $4 700 (about 188,000 – 210,000 UAH).
3. How to calculate the cost of turnkey installation?
Buying the kit itself (inverter, panels, batteries) is about 65-75% of the total cost of the finished system. For the station to work, additional costs must be taken into account.
The formula for calculating a turnkey solar power plant consists of the following elements:
Total cost = Equipment set + Mounting system + Electricity and protection + Installation work
1. Mounting system for solar panels
The panels must be securely fixed to the roof (sloped or flat) or to a ground-based metal structure. The fasteners are made of galvanized steel or aluminum, resistant to wind and snow (the panels withstand wind up to 2400 Pa and snow up to 5400 Pa).
- For 5 kW (8-9 panels): ~$250 – $400
- For 10 kW (16-18 panels): ~$500 – $800
2. Electrical fittings, cables and protection
For safe operation, you need a special solar cable (with ultraviolet protection), power cables for the battery, a solar power plant protection board (including DC and AC circuit breakers, fuses, grounding, and surge protection (SPS)).
- For 5 kW: ~$200 – $350
- For 10 kW: ~$350 – $550
3. Installation and commissioning work
The work of a professional team of installers includes: design, lifting and installation of panels, laying lines, assembling the protection shield, connecting the inverter and batteries, as well as programming the inverter operating modes. Typically, the cost of the work is about 15–20% of the cost of the equipment.
- For 5 kW: ~$400 – $600
- For 10 kW: ~$700 – $1,000
Final turnkey estimate (approximate):
- 5 kW turnkey station: ~$3 100 – $3 600 (140,000 – 160,000 UAH)
- 10 kW turnkey station: ~$5 800 – $7 000 (260,000 – 315,000 UAH)
Efficiency and savings tips from experts
To make your investment pay off faster, use simple but effective rules:
- Optimize consumption: Set the most energy-intensive appliances (water heaters, washing machines, dishwashers, pumps) to operate during daylight hours (11:00 AM to 4:00 PM). At this time, solar generation is at its peak, and you will use clean energy directly without draining your batteries.
- Minimize current losses: Never skimp on cables. Using a high-quality copper solar cable with the correct cross-section and minimum resistance allows you to save from 3% to 5% useful energy produced.
- Regular care: Solar panels get covered in dust, pollen, or bird droppings. Cleaning your panels with water just 2-3 times a year increases their performance by 10-15%.
Frequently Asked Questions (FAQ)
Can the system be expanded to 5 kW in the future? Yes, this is one of the main advantages of modern systems. A hybrid inverter allows you to easily scale the system: you can later purchase and connect additional battery packs to increase the battery life or deliver solar panels (the Sako 5.5 kW inverter supports a PV array of up to 6000 W).
Will the station operate without solar panels at all? Yes! If you have a limited budget at the first stage, you can purchase inverter and LiFePO4 battery. The system will work as a high-power uninterruptible power supply (UPS): when the network is available, it will quickly charge the battery, and during a power outage, it will instantly switch the house to autonomous power. The panels can be purchased and installed later.
Installing a hybrid solar station is a capital investment that fully pays for itself in the first year of operation. The kit includes: 5 kW (from 100,585 UAH for equipment) — an ideal starting option for most Ukrainian homes, which guarantees complete energy independence, comfort and peace of mind for your family under any conditions in the power system.
