FAQ

What reduces PV glass efficiency most significantly?

Temperature increases – for every 1°C above 25°C, efficiency drops 0.3-0.5%.

Can photovoltaic glass work in cloudy conditions?

Yes, but output decreases by 10-25% depending on cloud density.

How often should PV glass be cleaned?

In dusty environments, monthly cleaning maintains optimal performance.

Do colored PV glasses have lower efficiency?

Typically yes – blue-tinted glass loses 2-3% efficiency vs. clear variants.
