What is a 'bill of materials' of a PV module?

The ‘bill of materials’ (BoM) of a PV module include the encapsulants, front surface, back sheet (for mono-facial) and cell interconnections. An encapsulant is important for solar cell adhesion to the front and rear surfaces of the module.

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.

What is included in a BOM report for PV panels?

A typical BOM report for PV panels includes the following key components: Grade and type of solar cells (e.g., monocrystalline or polycrystalline). Supplier information, cell efficiency, and quality grade. We’ve extensively covered cell efficiency and quality grades in our previous article about EL Test.

Can SLS glass be used in PV modules?
