Recom Technologies and Derex Develop the 1st Floating Solar Power Plant in Latvia, with 2.1 MW of RECOM Panther 550Wp Solar Modules.

Recom Technologies and Derex collaborated to create the first floating solar power plant in Latvia.

The floating station, with a capacity of 2.1 MW, is located on the water surface via floating pontoons and will provide power to the ‘Sloka’ wastewater treatment plant in Jurmala, showcasing the potential of solar energy as a sustainable power source.

Solar Energy at the Sloka Wastewater Treatment Plant: Cost and Emission Reduction

The ‘Sloka’ WTP consumes 40% of the total energy expenses of ‘Jūrmalas ūdens’, the utility company that operates the wastewater station. The installation of the solar station allows ‘Sloka’ to generate its own energy, effectively reducing the electricity costs for ‘Jūrmalas ūdens’ and decreasing the organization’s dependence on fluctuations in energy market rates. The project aims to reduce carbon dioxide emissions by 231,657 tons per year, decreasing the region’s carbon footprint and helping to preserve its resources in the long term, while maintaining ecological balance.

Benefits of Renewable Energy in the Baltic Region

Over the guaranteed operational life of 30 years, the floating solar station will be able to operate continuously in the harsh local environment. Thanks to specially designed solutions, the system is resistant to salt, fog, snow, and ice – typical precipitation of Latvia’s climate – as well as to the effects of ammonia and hydrogen sulfide on the station’s materials and equipment. Floating stations have not yet gained significant popularity in Latvia and the Baltic region, although this is the safest option for the typical fragile ecosystems of the region. The ‘islands’ on the water protect the surface from excessive sunlight, preventing the growth of underwater vegetation and preserving the balance and purity of the aquatic ecosystem, said Yulia Nikulina, project manager and Director of the green energy division at DEREX.

Additionally, the aquatic environment is ideal for the panels themselves, as the natural cooling effect of the water helps the station maintain a stable temperature. Even greater performance from the station is achieved with bifacial panels (front and back), which absorb sunlight reflected off the water surface. The project includes 3,820 RECOM Panther 550Wp Half Cut mono bifacial double glass modules, each with a capacity of 550 Wp. They are installed on the ‘island’ at an angle of 12° to optimize solar light collection.

While in Brazil a 10-story building takes 2 years to complete, in China a company stacks pre-fabricated modules and raises the entire building in just 28 hours and 45 minutes.

BRICS is preparing a payment system inspired by the Brazilian PIX that will allow direct transactions between countries using national digital currencies without relying on the dollar or Western banks as intermediaries.

The oldest tree in the world, alive since before the birth of Jesus Christ, is cut down in a scientific study and the case changes environmental preservation rules.

An entire island in the Pacific wants to surround itself with a colossal barrier against the ocean to try to escape increasingly violent waves and not be swallowed by the sea in the coming decades.

After ten days orbiting the Moon, science confirms that the astronauts of the Artemis II mission return with altered bodies.

Peru built a tunnel at an altitude of 4,738 meters cutting through the Andes Mountains, and the road leading to it reaches 4,818 meters, making it the highest paved road in the entire world.

Seen from space, an image taken by an astronaut shows in Argentine Patagonia the exact point where a colossal glacier, a turquoise-blue lake, and a greenish arm of water meet, creating one of the rarest and most impressive landscapes in the region.

Instead of torpedoes, American submarines will now launch autonomous drones through the same tubes — and when the drone reaches the surface, it transmits everything the submarine sees at the bottom of the ocean.

Cyclist from Suzano tackles 928 km to Vitória on a bamboo bike he made himself and draws attention with his sustainable achievement.

This 3,000-year-old invention cools any house by 15 degrees without spending a cent on energy, and the reason no one talks about it is that the industry profits billions selling machines designed to break down.

Scientists glued moss to the exterior of the International Space Station, exposed it to vacuum, radiation, and temperatures of -196°C for 283 days, and more than 80% of the spores survived, regenerated on Earth, and managed to reproduce.

Valued at $20 billion, the galleon San José, the “Holy Grail of shipwrecks,” has finally begun to be explored: robots retrieved bronze cannons, coins, and 18th-century Chinese porcelain from the depths of the Caribbean after 318 years.
