New Modern Solar Energy Capacities in Lapovo – DeLasol North

Every new megawatt of energy produced from renewable sources represents an important step towards the energy transition and the development of a more modern and resilient energy system. Guided by this idea, at the end of March this year, MT-KOMEX commissioned the DeLasol North solar power plant in Lapovo, once again confirming its expertise and experience in developing and constructing modern solar power plants.

The facility, with an installed capacity of 9.9 MW, covers an area of 15.85 hectares and consists of 16,830 solar panels manufactured by Aiko Solar, each with a capacity of 650 Wp. The panels are mounted on a supporting substructure at a 20-degree angle to the horizontal and oriented towards the south, enabling optimal use of solar radiation and higher electricity generation during the summer months. All generated electricity is delivered to the distribution system, contributing to an increased share of renewable energy sources and the further development of Serbia’s sustainable electricity system.

Energy conversion is handled by 100 inverters, each with a capacity of 100 kW, manufactured by Huawei GmbH, while transmission is carried out via 10 power transformers with a capacity of 1,000 kVA. The power plant is also equipped with a lightning protection system, further improving the safety and reliability of the facility’s operation.

The average annual specific electricity generation is estimated at 1,328.9 kWh per installed kilowatt, confirming the high production potential of the location and the carefully designed technical solution.

Interestingly, approximately 10 percent of the installed capacity is oriented towards the southwest. Although such a configuration results in slightly lower total annual electricity generation than an optimal south-facing orientation, it enables higher production in the afternoon and evening hours, when market electricity prices are usually higher. This optimizes the market value of the generated energy and increases the power plant’s overall revenues.

World Sun Day and DeLasol North Power Plant Day

To mark the commissioning of the DeLasol North power plant, a ceremony was organized and attended by colleagues, the professional public, partners, and friends of MT-KOMEX.

The event combined socializing with the celebration of a successfully completed project, while also giving those present the opportunity to learn more about the operation of the solar power plant. Symbolically, the ceremony was held on World Sun Day, further emphasizing the importance of using solar energy and developing renewable energy sources in Serbia.

As part of the event, the Renewable Energy Sources of Serbia Association presented Director Miloš Kostić with an award marking five years of MT-KOMEX’s membership in the association, as recognition of the company’s long-standing contribution to the development of renewable energy sources and the advancement of the green transition in Serbia.

Company Director Miloš Kostić took the guests on a tour of the facility, during which he presented the key technical solutions of the system and the way the power plant operates. On that occasion, those present had the opportunity to learn about the project’s technical characteristics and its contribution to the domestic energy sector.

Kostić also pointed out the differences between conventional oil-filled and dry-type transformers. Unlike traditional solutions, dry-type transformers do not use oil, eliminating the need for regular oil quality checks, oil replacement, and the disposal of oil as potentially hazardous waste. In addition to environmental advantages, such solutions provide enhanced fire protection, making them a suitable choice for modern energy facilities.

The DeLasol North project demonstrates how modern technological solutions, expertise, and dedication can be integrated into a system that generates clean energy and contributes to a more sustainable future.

The DeLasol solar power plant, with a capacity of 9.9 MW, is also located at this site and was commissioned in April 2024. Together with the DeLasol North power plant, this area forms the company’s largest solar energy complex in Serbia, developed in several phases at the same location. The true scale of the complex was best experienced by guests on a quad bike tour, designed to offer a simple and dynamic way to visit the entire power plant.

MT-KOMEX views sustainability as a principle applied at every level — from design and construction to the operation and maintenance of the facilities themselves. It is precisely in this spirit that the agrosolar concept was developed at the Lapovo site, where more than 130 sheep help maintain vegetation in the power plant area.

Instead of conventional mowing and mechanized maintenance, the land is maintained naturally, reducing the need for machinery, optimizing costs, and further strengthening the system’s overall sustainability.

In this way, the same area gains a dual function — the production of clean electricity and the agricultural use of land. This approach increasingly demonstrates that solar power plants can simultaneously integrate energy production and agricultural land use in a mutually compatible way.
