Field capacity of solar glass

How much solar energy does commercial glass produce?

Base-line commercial glass has a solar transmission of 83.7%. I.e. 16.3% of the sun's energy do not even get to the PV material. The energy loss is due - in equal parts - to reflection on the surface and absorption within the glass due to iron impurities. The density of glass is about 2,500 kg/m 3 or 2.5kg/m 2 per 1mm width.

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 are the characteristics of glass for solar applications?

For solar applications the main attributes of glass are transmission, mechanical strength and specific weight. Transmission factors measure the ratio of energy of the transmitted to the incoming light for a specific glass and glass width. Ratio of the total energy from an AM1-5 source over whole solar spectrum from 300 - 2,500nm wavelength.

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.
