Global Solar PV Price Drop: What the Numbers Say

The solar industry has witnessed a 62% price reduction for photovoltaic panels since 2018, according to BloombergNEF data. Let''s break down the annual changes:

• 2018: $0.38 per watt
• 2020: $0.27 per watt
• 2022: $0.23 per watt
• 2023: $0.18-$0.21 per watt

3 Key Drivers Behind Falling Solar Prices

1. Manufacturing Scale-Up

China''s solar production capacity grew 400% since 2018, creating economies of scale that benefit global buyers.

2. Technology Improvements

New PERC and bifacial panels deliver 21-23% efficiency compared to 15-17% in 2018 models.

3. Supply Chain Optimization

Automated production lines now output 10,000 panels daily versus 2,500 five years ago.

"The $0.15/Watt barrier will likely break by 2025 as TOPCon and heterojunction technologies mature."
