Turnkey Solar Power Plant Installation – Montenegro and Serbia

Topla Kuća designs, supplies and installs solar power plants for homes, holiday houses, hotels and businesses. We build hybrid and off-grid solar systems with batteries, as well as on-grid systems connected to the grid. Solar systems reduce electricity costs and give energy independence. One contractor manages the entire job: from measuring the roof to commissioning and service.

What turnkey solar panel installation includes

• Site visit, roof measurement and analysis of electricity consumption
• Calculation of system power, battery capacity and annual energy production
• Solar system design and equipment selection
• Equipment delivery: solar panels, inverter, batteries, mounting structure, cables and protection
• Installation of the mounting structure and solar panels on the roof or a carport
• Connecting the inverter and batteries, configuration and commissioning
• System monitoring and user training
• Service and maintenance

How the work goes: 5 steps

1. Site visit and measurement

We check the roof, orientation, shading and electricity consumption based on your power bills.

2. Calculation and quote

Within 24 hours you receive a system proposal: power, batteries, expected production, price and payback period.

3. Equipment supply

Panels, inverter, batteries and mounting structure arrive at the site as one set, matched to the project.

4. Installing the solar panels

Installation time depends on the condition of the roof and the system capacity, and the work is carried out without damaging the roof.

5. Commissioning and maintenance

We connect the system, configure the inverter, train the user and remain available for service.

Solar systems we install

• Hybrid solar system with batteries. Works together with the grid, and during a power outage the household uses energy from the batteries.
• Off-grid (autonomous) system. For holiday houses and buildings without a grid connection. Solar system for a holiday home.
• On-grid system. No batteries; it reduces the electricity bill, and surplus energy goes to the grid.
• Solar power plants for hotels, restaurants and businesses. Rooftop systems and solar car parks for higher consumption.

Equipment and warranty

We install equipment from Deye, Afore and Felicity Solar: hybrid inverters, lithium LiFePO4 batteries and solar panels. All equipment comes with a manufacturer warranty and service. You can view the equipment in the catalog: solar panels, inverters and lithium batteries.

Cost of solar panel installation

The price depends on system power, battery capacity, roof type and distance to the site. That is why we give a quote after measuring, when we know the actual consumption and installation conditions. You can get an approximate estimate right away in the calculator. The payback period of our projects is 4–7 years, and long-term savings grow with the price of electricity.

Montenegro and Serbia

In Montenegro we work from Đenovići near Herceg Novi and travel to sites on the coast and inland. So far we have installed solar systems in Tivat, on Luštica, in Krimovica, Grahovo and Kolašin. Most often these are hybrid solar systems with batteries for houses, villas and apartments, where backup power during an outage matters. More about these systems: Solar power plants with batteries in Montenegro.

In Serbia, a household with the status of a customer-producer (kupac-proizvođač) can apply for a state subsidy. We handle the project, equipment delivery and installation, while the application for the subsidy is submitted by the property owner. A 5 kW hybrid system with a battery costs from about 990,000 dinars.

Frequently asked questions

How long does solar panel installation take?

It depends on the condition of the roof and the system capacity. The time can increase if difficulties arise during installation: for example, if old roof tiles start to crack, repairing or replacing them extends the work. Larger solar power plants for hotels and businesses are built according to an agreed work plan.

Is the roof damaged during installation?

No. We choose the mounting structure to suit the roofing type, and the panels are installed without damaging the roof.

How much energy does a solar system produce?

A 5 kW system produces about 7,000 kWh per year on average. Exact production depends on the location, tilt and orientation of the roof.

Can I add batteries to an existing on-grid system?

Yes. We add a hybrid inverter and batteries, so the system keeps working even when the grid power is out.

Do you build solar power plants for businesses and hotels?

Yes. We design and install systems for commercial buildings, including rooftop power plants and a solar car park of over 120 kW.
