One secret

Let us tell you a secret.

Over many years of working with renewable energy and listening to our customers, we have come to one conclusion: the greatest benefit of solar energy is not the savings, even though savings are the main reason people invest. It is the comfort of living, and even more, a sense of satisfaction with oneself. Today, care for the environment has joined them.

A solar installation is the only investment in a home that pays for itself. Everything else is an expense; it is only a matter of time. The more you use, the sooner it pays off.

And there is one more benefit… which we'd tell you when we meet.

Why a solar plant

The sun shines on your roof 2,000 hours a year. You still pay the grid for power.

Tap a part of the house. Switch to night to see where the power comes from then.

Tap a part of the house to see what it does.

Every kilowatt your roof produces is a kilowatt you do not pay for.

Serbia gets 2,000 to 2,300 hours of sunshine a year, according to measurements by the national weather service.

Solutions

Solar power plants. From design to monitoring.

We design the plant for your property, install the panels and inverter, connect everything up to the electrical panel and track how it works.

Installing solar panels on the roof of a family house

01 · ElectricitySolar power plant

Power from your own roof

ELSOL ESM panels turn sunlight into electricity. An on-grid plant works together with the grid and lowers your bill, and an off-grid plant powers a property that has no grid connection.

Power even when the grid is down

Panels, grid and batteries together. By day, extra power charges the batteries. In the evening the house runs on them, and when the grid goes down, it keeps running.

History

Milić Nikolić, founder of ELSOL.

The founder of ELSOL, Mr. Milić Nikolić, an electrical engineer, was a visionary. In the difficult 1990s he managed to build the company on sound foundations, on work and knowledge, always looking for new technological solutions and investing in new knowledge and technology.

We, the heirs of his character and his work, strive to maintain the quality of his work and business.

To Mića Nikolić, cheers!

About us

We started with collectors. In Požarevac, in 1993.

For more than 30 years we have made and installed solar collectors for homes, hotels, care homes, pools and industry. Today we put the same experience with roofs, installation work and the sun into solar power plants.

“We put in a solar collector to heat the water in a 220 liter tank with two heat exchangers. The water is hot, and I am very happy.”

Measured result

22,602 kWh

That is how much solar energy one building with a pool got during 2012. From May to September the gas boilers were off, and the hot water and pool kept running.

Questions

What people ask us most.

Pick a question. The answer arrives as a message from us.

How big a solar plant do I need?

It depends on how much electricity you use in a year. Send us your electricity bill or your yearly use in kWh, and we work out the power and the number of panels.

Does a solar plant work during a power outage?

An on-grid plant switches off during an outage, for the safety of people working on the grid. If you need power without the grid, we build a hybrid system with batteries, which switches to the batteries in under 10 ms.

Do you monitor the plant after installation?

Yes. We have monitoring for every solar plant we have built, so we can see how each system performs.

Are there subsidies for solar plants?

Yes, through the energy renovation program in municipalities. How to apply is explained on the Subsidies page.

Do you also install heat pumps?

Yes. We can connect a heat pump to your solar plant, so your heating runs on power from your roof. More on the Heat pumps page.

How long is the warranty?

The ELSOL ESM 600–620 W panel has a 30 year warranty, the 450 W panel 20 years, and power output 30 years. The Blue Tec Al collector has 20 years.

Will collectors give me hot water in winter too?

Yes. In winter, with sunshine at -5°C, the water in the collector reaches 35 to 40°C. The water heater then only tops up the rest with electricity or from central heating.

Your question is not here?

Ask us directly. For a solar plant, your power bill and your town are enough.

Every sunny day without a solar plant is paid to the grid.

Every month you pay for power your roof could have produced. The quote does not commit you to anything, and afterward you know the exact price.
