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.

Why should you choose Onyx Solar Photovoltaic Glass?

The multifunctional properties of photovoltaic glass surpass those of conventional glass. Onyx Solar photovoltaic glass can be customized to optimize its performance under different climatic conditions. The solar factor, also known as “g-value” or SHGC, is key to achieve thermal comfort in any building.

What U-values does Onyx Solar offer?

Onyx Solar photovoltaic glass also offers a wide range of U-Values, according to the architectural spec. We just follow the design intention and manufacture the glass to meet these specifications. Accordingly, we offer single laminated, double and triple glazing, Air and Argon chambers, and other configurations.

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.
