Technical FAQs 4

What G-value should a Photovoltaic Glass have?

Photovoltaic glass can be customized to achieve a solar factor between 6% and 41%. A low g-value is desirable to prevent overheating, especially in warm climates, as it prevents the interior temperature from rising too high due to the greenhouse effect.

What is Photovoltaic Glass?

We have manufactured the first photovoltaic glass in the market that comes with low-emissivity properties, provides UV and IR filter, promotes natural light, and generates power. All our solutions offer a multi-functional value. The multifunctional properties of photovoltaic glass surpass those of conventional glass.

Can tempered glass be used in solar modules?

The only feasible way for tempered glass to be widely used in solar modules is its application in single-glass modules. The prevailing benchmark for hail resistance, which stipulates that solar modules must be capable of withstanding impacts from hailstones up to 35mm in diameter, may fall short in areas frequently subjected to larger hailstones.

Why should you choose glass in a PV module?

The choice of glass in a PV module has become a key consideration in efforts to improve durability in the face of extreme weather conditions.
