Technical FAQs 4

How much iron is in solar glass?

As one of the most crucial components of solar installations, photovoltaic glass demands high transparency. Therefore, strict requirements are imposed on the iron content in the silicon raw materials used for producing solar glass, with Fe2O3 content typically ranging from 140 to 150 ppm.

How does iron affect the color of glass?

The presence of iron impurities not only causes the glass to become colored but also increases its heat absorption rate, thereby reducing its light transmission. Iron in glass comes from raw materials, refractory materials, or metal equipment used in production, and it is impossible to completely avoid its presence.

How does glass affect solar panel efficiency?

The glass covering a solar panel plays a significant role in protecting the cells while influencing how effectively they convert sunlight into energy. Understanding how glass thickness and composition affect solar panel efficiency is essential for optimizing their performance.

What factors affect solar panels' efficiency?

Both the thickness and composition of the glass in solar panels are crucial factors affecting their efficiency. Thicker glass offers better durability but might limit light transmission, while glass composition, such as the use of anti-reflective coatings and low-iron glass, can enhance light penetration and overall performance.
