200kW Solar Power Plant For High-Altitude 4000m Areas

How to install a 200kW solar power plant in a rugged, high-altitude area?

Located in Yunnan Province, China, the project presented unique challenges due to its location and local farmers’ specific requirements.

Solar energy company PVMars bravely broke through and after an in-depth understanding, customized a 200kW solar power plant for them.

This case illustrates PVMars’ solar system design considerations and solutions. To ensure the successful installation and operation of this high-altitude solar farm.

A touch of blue against the 4000-meter mountain:

How off grid solar system work

Seen from a distance, hundreds of solar panels look like a blue field. This is particularly prominent in the rolling mountains.

One of the major issues when installing solar power plants at high altitudes is extreme environmental conditions, including low temperatures and challenging terrain. PVMars addresses these challenges through tailor-made design.

Battery options for a 200kW solar plant:

This is a solar system installed at an altitude of 4,000 meters, far away from urban power sources and underdeveloped transportation.

Batteries are critical as a backup power source.

As winter approaches, temperatures at high altitudes may drop to minus 20 degrees Celsius or lower, so we need to think carefully about this project.

Battery in solar energy storage system

Not only do these 2V batteries have a larger capacity than lithium batteries, but they also have excellent cold resistance.

In environments with temperatures as low as -40 degrees Celsius, the 2V battery system remains stable, ensuring uninterrupted power supply during severe winters.

The 2V1500Ah gel battery has the following parameters:

Model: MG2V- 1500

How to install 200kW solar panels?

Installing hundreds of solar panels on uneven and steep surfaces is not easy.

PVMars uses specially designed high-strength solar panel brackets to fix photovoltaic panels to the ground even in loose soil conditions.

This innovative solution prevents solar panel damage and ensures maximum energy capture.

How does a 200kW solar power plant power a water pump?

One of the unique challenges faced by local farmers is the need for powerful pumps to pump river water to 4,000 meters.

Electrical requirements to pump water to such heights require powerful pumping systems.

PVMars designed and integrated two 80kW three-phase AC water pumps with variable frequency drives (VFD).

PVMARS VFD solve your inductive load startup problem

VFDs allow for a soft start of the water pump, reducing instantaneous power surges.

This design solution optimizes power consumption and reduces the overall cost of purchasing a high-capacity solar inverter.

200kW off-grid solar system provides a reliable power source for remote mountainous areas.

Through PVMars’ installation team, cold-resistant 2V batteries, and optimized pumping solutions, we overcame the numerous challenges posed by the terrain and climate.

Let local farmers live a sustainable and pleasant life and meet their energy needs at any time.
