In 2021, the photovoltaic (PV) glass industry experienced unprecedented growth driven by global renewable energy commitments. This article explores key trends, applications, and data-backed insights into solar glass demand – a critical component for modern solar panels and building-integrated photovoltaics (BIPV).

Why Photovoltaic Glass Became a 2021 Game-Changer

The year 2021 marked a turning point for solar energy adoption, with PV glass demand increasing by 23% year-over-year according to SolarPower Europe. Three primary drivers fueled this surge:

• Government net-zero carbon pledges at COP26
• Architectural shift toward energy-efficient buildings
• Improved solar glass efficiency rates (now averaging 18-22%)

Key Market Data: 2021 PV Glass Landscape

Metric	Value	Growth vs 2020
Global Production Capacity	15.8 billion m²	+19%
BIPV Installations	4.3 GW	+31%
Average Price per m²	$28.50	-7% (economies of scale)

Emerging Applications Driving Demand

While traditional solar farms still account for 62% of PV glass usage, innovative applications are reshaping the market:

1. Solar Skins for Commercial Buildings

Transparent solar glass facades became a status symbol for eco-conscious corporations. The "see-through solar" technology allowed companies like EK SOLAR to deliver 40%-efficient window solutions for high-rise buildings.

2. Agricultural Photovoltaics

Semi-transparent glass panels enabled dual-use farmland, protecting crops while generating electricity. Japan''s solar-sharing farms achieved 93% light transmission with 15% energy conversion rates.
