How much does a solar module weigh?
Typical dimensions of a domestic PV module are 1.4–1.7 m 2, with >90% covered by soda–lime–silica (SLS) float glass. 9 The glass alone weighs ~20–25 kg since the density of SLS glass is ~2520 kg/m 3. This presents engineering challenges as current solar panels are rigid and need strong, heavy support structures.
Why is glass front sheet important for PV modules?
In addition to optical and environmental performance, the mechanical performance of PV modules is also of vital importance, and with the glass front sheet constituting a high proportion of the mass of PV modules, it also impacts on mechanical properties of the PV module composite.
Can SLS glass be used in PV modules?
SLS glass is ubiquitous for architectural and mobility applications; however, in terms of its application in PV modules, there remains room for improvement. In the current paper, we have reviewed the state of the art and conclude that improvements to PV modules can be made by optimizing the cover glass composition.
How important are thermal and mechanical properties in a PV system?
Optimization of the mechanical and chemical properties is of course interesting and important from a PV perspective; however, the thermal properties remain the most important from the perspective of being able to manufacture the glass.
Which cover material should be used for PV modules?
Currently, 3-mm-thick glass is the predominant cover material for PV modules, accounting for 10%–25% of the total cost. Here, we review the state-of-the-art of cover glasses for PV modules and present our recent results for improvement of the glass.
Why do solar cells have a cover glass?
This is augmented by broadband down-shifting of absorbed UV photons and re-emission as visible photons available for conversion by the solar cell. The compound effect of these compositional changes to the cover glass thereby enables both increased efficiency and increased lifetime of PV modules.
