6 FAQs about [Solar backsheet accounts for the price of photovoltaic modules]
What is a PV backsheet?
PV backsheets play a very important role in ensuring a solar module lifetime of 25 years or even longer. They have the function of protecting the solar cells, the metallic contacts and the encapsulant against ultraviolet radiation, as well as against the penetration of water vapour and moisture from the atmosphere.
Does a backsheet affect the efficiency of a PV module?
The efficiency of a PV module is influenced by the backsheet. In this respect, and for backsheets with similar global reflectances, an improvement in efficiency of 0.22% rel. can be achieved in a standard PV module with the use of a backsheet having a low specular reflectance compared with another having a high specular component.
What is a solar backsheet?
Initially, solar backsheets had a three-layer structure (PVDF/PET/PVDF). The outer PVDF layer offers excellent environmental corrosion resistance, the middle PET layer provides insulation, and the inner PVDF layer, combined with EVA, ensures good adhesion.
Why do solar panels have backsheets?
Backsheets act as insulators, safeguarding the system against temperature extremes and mitigating thermal stress. Additionally, they help regulate solar heat absorption by preventing high-energy photons from reaching the photovoltaic cells, thus averting overheating that can compromise performance.
Do you need a backsheet for solar panels?
In most cases, normal backsheets are sufficient to meet the requirements of PERC (Passivated Emitter Rear Cell) solar panels. However, when it comes to N-type or N-type TOPCon (Tunnel Oxide Passivated Contact) solar panels, a more specialized approach is necessary.
Why do photovoltaic cells need a backsheet?
Water and dust particles can lead to corrosion and pitting, posing a threat to photovoltaic cells. The backsheet’s role is to shield against moisture-related damage, including corrosion of electrical connections, insulation degradation, and the risk of short circuits.
