Customer requirement: A multi-megawatt (MW) solar photovoltaic power plant.

Our solution:

• Installed Capacity: Configured at 3.5 MWp. This exceeds the base load, primarily to provide a margin for system losses and component degradation.

• Module Selection:  Utilizes 550Wp+ high-efficiency monocrystalline bifacial modules, aiming to further reduce the cost per kilowatt-hour by improving power generation efficiency.

• Mounting System:  Recommended use of tracking or fixed-tilt systems (hot-dip galvanized steel), requiring customized structural design based on the geographical location and wind speed in Southwest China.

• Land Area: Estimated land requirement of 4.2 - 5.2 hectares (based on industry experience of 1.2 - 1.5 hectares/MW).

3. Energy Storage System (BESS)

The energy storage system is a critical component in ensuring the quality of power supply to the mining area:

• Storage Capacity: Configured at 3 MWh. Primarily used to provide basic load at night or support short-term operation in the absence of sunlight.

• Battery Type:  Uses lithium iron phosphate (LiFePO4) batteries.  Offers advantages of high safety, long cycle life (greater than 6000 cycles), and high energy density.

• Power Capacity: Configured at 2 MW. Focused on meeting rapid charging and discharging needs to handle load fluctuations.

• Core Equipment Components:

• Power Conversion System (PCS)

• Battery Management System (BMS)

• Energy Management System (EMS)

• Function: Achieves millisecond-level coordinated control between photovoltaic, energy storage, and the grid/generator.
