6 FAQs about [Is the photovoltaic panel backplane hard Why ]

What happens if a solar panel backsheet fails?

The main cause for solar panel degradation due to back-sheet failure is the delamination of the backsheet or the formation of cracks in the material. When the backsheet fails, the inner components of solar panels are exposed to external agents, and the lifespan of PV modules is reduced.

Why is polymeric backsheet degradation important in photovoltaic industry?

The insulation degradation in polymeric backsheets has been identified as a main cause of catastrophic accidents induced by short circuit or ground faults in photovoltaic module. To ensure quality, the photovoltaic industry is therefore faced with urgent demand in discovering degradation mechanisms.

Why do we need a backsheet for PV modules?

In addition, the backsheet can allow acetic acid to pass through effectively to reduce internal corrosion, and the excellent optical properties of such backsheets can also improve the output of PV module. The future of the co-extrusion process for the production of backsheets requires a high degree of attention.

Does electrical-induced degradation affect PV backsheet performance?

Electrical-induced degradation is also an important factor that affects PV backsheet easily during the operation of PV system. Since 2011, the influence of electrical-induced degradation on the performance of PV backsheet has received considerable attention, which provides significant theories and methods for subsequent research.

What are the problems with PV backsheet?

PV backsheet can suffer from several stressors in specific ambient; (c) Two main types of defects on backsheet observed in the field, including blistering (left) and cracking (right). The circles in the images indicate cracks and bubbles respectively.

Are co-extruded backsheets based on pp suitable for PV modules?

Summarized, co-extruded backsheets based on PP show great potential to be a valid replacement of standard PET based backsheets in PV modules. On the one hand, the PP backsheet so far proved excellent stability, exhibiting no severe material degradation after extended exposure to temperature, humidity and irradiation.
