1GW = 1000MW = 1,000,000kW = 1,000,000,000W. For a 1GW photovoltaic power station, assuming an average daily effective power generation duration of 4 hours, it can generate 4 million kWh per day. If one household consumes 10 kWh of electricity a day, this means a 1GW PV plant can meet the daily electricity demand of 400,000 households.
Currently, the mainstream efficiency of the widely adopted N-TOPCon solar cells on the market stands at 25.2%, with a power output of 8.39W per cell. Using these figures as the baseline, we can calculate the required quantities of products across the industrial chain.
1GW = 1,000,000,000W ÷ 8.39W = 119,189,511 cells, approximately 120 million cells.
The quantity of silicon wafers matches that of solar cells, also around 120 million pieces.
Calculated based on the most prevalent 72-cell module type rated at 585W per unit: 1GW = 1,000,000,000W ÷ 585W = 1,709,401 modules, roughly 1.71 million modules.
Generally speaking, the land occupation of a power station cannot be calculated merely by the area of PV modules. Multiplying the module area by a factor of 3 is a common practice to obtain the total site area. The typical dimension of the 72-cell module is about 2.278m × 1.134m ≈ 2.58 m². The total station land area is calculated as: 1,710,000 × 2.58 × 3 ≈ 13,235,400 m² = 20,753.1 mu ≈ 21,000 mu.
The above values are theoretical estimates, and actual data will not deviate significantly.
