How durable is Photovoltaic Glass?

It’s important for photovoltaic glass to be durable, but it also needs to transmit light to the PV cells. Without a high degree of transparency and solar radiance — a measurement of how much solar energy can pass through the glass — durability doesn’t matter all that much, as energy production will fall steeply.

What is Photovoltaic Glass?

Our photovoltaic glass offers a cutting-edge solution for both new construction and renovation projects. When integrated into ventilated façades, this glass enhances building aesthetics while providing key benefits such as radiation protection, thermal and acoustic insulation, and improved occupant comfort.

Is glass a good choice for solar panels?

Glass is highly transparent and lets up to 99.95% of all light pass through it. 2 This means the large majority of the sunlight hitting the face of your panels will be transmitted to your solar cells for energy production. Glass varies in degrees of transparency, but most types of clear glass are suitable for PV panels.

Is Photovoltaic Glass a good investment?

Photovoltaic glass not only offsets conventional building material costs but also provides a tangible return on investment through energy generation. With an average payback time of 4 years and yearly ROIs of up to 20%, it stands as a sound economic choice.

Do rooftop solar panels have glass?

Virtually every rooftop solar panel you see has a protective sheet of glass over the solar cells. Glass is one of the key components of a photovoltaic (PV) panel, and the material is used for very specific reasons.

Why is cheap Photovoltaic Glass better?

As mentioned above, cheap photovoltaic glass is less resistant to extreme heat, extreme cold and changes in moisture. Low-quality glass is more likely to expand and contract with changes in outdoor conditions, which means the panels are more likely to fail in a shorter amount of time.
