Supply and Installation of 9 Polar Photovoltaic Systems in Peleduy, Russia

This project, located in the heart of Siberia, represents one of the most complex challenges undertaken by Enviroearth. It involved the supply and installation of nine high-performance polar photovoltaic systems designed to power a seismic station. Conducted in collaboration with our local partner and a team of subcontractors, this ambitious project was carried out over a three-week period under particularly harsh weather conditions.

The Enviroearth team faced temperatures dropping as low as -20°C, making on-site work demanding and occasionally interrupted. The construction sites were spread across remote areas, and damaged roads significantly complicated logistics and the transportation of materials.

Technical specifications of the installed system:

• High-performance polar power system, capable of operating in extreme weather conditions.

• 10.24 kWh lithium iron yttrium phosphate (LiFeYPO4) batteries, optimized for loads ranging from 20 to 50 W.

• Full active balancing for optimal energy management.

• Operating temperature range from -45°C to +85°C, with a heating option for better performance at low temperatures.

• Low self-discharge rate, not exceeding 3% per month at 20°C.

• Robust system with three input boards, each handling 25A current.

This project not only overcame major technical and logistical challenges but also demonstrated Enviroearth's expertise in executing projects in extreme environments.
