Solar power generation has experienced significant growth in the last few years, and according to the International Energy Agency (IEA), solar photovoltaic (PV) generation is set to increase further by record amounts. An average annual generation growth of 25% is needed from 2022-2030 to meet the Net Zero Emissions by 2050 Scenario set out by the IEA.
With heavy investment on a global scale, solar power farms are being developed worldwide, increasing the demand for photovoltaic cable. However, what needs to be considered when manufacturing photovoltaic cable?
We asked Meenali Parsekar, Product Manager, Wire and Cable at Avient, to find out.
1. What are photovoltaic cables, and how are they used?
Photovoltaic cables are low-voltage, high-weather-resistant cables that connect solar panels to an inverter. They are specifically designed to carry the electricity harvested from solar panels to the battery that stores the energy.
2. What types of polymers are typically used for photovoltaic cables?
Cross-linked polyethylene is typically used to produce this type of cable. Polymers must be cross-linked to withstand the high temperatures generated by the metal wires they protect.
3. What unique characteristics should a quality photovoltaic cable have?
4. What challenges do solar panel cables present?
5. How can Avient help?
Avient has recently launched a portfolio of cross-linkable formulations for photovoltaic cable, ECCOH™ XL Cross-Linkable Solutions (ECCOH XL 8148), that achieve the key characteristics listed above. They are cross-linked using sioplast technology and offer good processing and line speeds. Avient’s Technical Services Team can assist with material testing and processing optimization.
