• Gujarat Renewable Energy Park (India): A 30 GW hybrid solar-wind park under development.

How Does a Photovoltaic Power Station Work?

While massive PV power plants look like endless seas of panels, their operation can be explained in four simple steps:

1. Capturing Sunlight (Solar Cells): Solar panels use the photoelectric effect to convert photons into direct current (DC).

2. Collecting Power (PV Arrays): Thousands of solar panels are connected in series and parallel to create a strong DC output.

3. Converting Current (Inverters): Inverters transform DC into alternating current (AC), making the electricity grid-compatible.

4. Boosting Voltage (Transformers): Substations increase the voltage for long-distance transmission into the national grid.

Simplified Workflow

Sunlight → Solar Cells (DC) → PV Array → Inverter (AC) → Transformer → Grid → Homes & Industry

️ Smart Technology in Modern PV Power Stations

• Solar tracking systems: Panels rotate with the sun to increase efficiency by 15–25%.

• O&M solutions: Drones, AI monitoring, and cleaning robots ensure stable and optimized operation.

 Conclusion

From China’s Tengger Desert Solar Park to Egypt’s Benban Solar Farm, the world’s largest photovoltaic power stations demonstrate the scale and impact of solar energy. At the same time, their underlying principle remains simple: converting sunlight into electricity through the photoelectric effect.

With upcoming mega solar projects in China, India, and Australia, photovoltaic power will continue to reshape the global energy landscape.
