INFORMATION & IDEAS
PV backsheets need to have an optimum blend of three key properties – weatherability, mechanical strength, and adhesion – to perform in harsh climates for 30 years and enable reliable and safe operation of PV modules.
Focusing only on lowering the system’s cost per Watt, can reduce the system’s expected power output over its actual lifetime and therefore increase the levelized cost of energy (LCOE). Consequently this can impact the overall return on investment of PV projects.
PV system quality starts with quality materials. Today’s IEC standards do not predict actual panel aging in the field. Find out about the recommended DuPont Module Accelerated Sequential Testing (MAST), as the new standard in accurate, predictive backsheet field testing.
Glass/glass panels may not be as robust and durable as you think. Field observations point to higher power degradation, corrosion and glass breakage in these types of panels. Find out more about the types of risks that can be associated with this technology.
Hot spots can be caused by a variety of issues, including shading, soiling, cell damage or cell mismatch, and can lead to serious power degradation of the system. Some hot spots may be remedied by using backsheet materials with the highest thermal stability. Find out more about the recommendations from DuPont.
