Solar glass bulk density

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.

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 is the density of glass?

The density of glass is about 2,500 kg/m 3 or 2.5kg/m 2 per 1mm width. Typical crystalline modules use 3mm front glass, whereas thin-film modules contain two laminated glass layers of 3mm each for front and back. As a result, assuming 3mm glass, 96% of the weight of a thin-film module and 67% of a crystalline module is glass!

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.
