6 FAQs about [The temperature of photovoltaic panels during pyrolysis]
What happens during pyrolysis of silicon PV solar modules?
During the thermal treatment (pyrolysis) of silicon PV solar modules, hazardous byproducts could get released into the environment. In a study reported earlier, the PV module is placed inside a closed furnace and heated at 500 °C for pyrolysis, and complete degradation of the encapsulant (EVA) is achieved .
How does PV module pyrolysis work?
In a study reported earlier, the PV module is placed inside a closed furnace and heated at 500 °C for pyrolysis, and complete degradation of the encapsulant (EVA) is achieved . Later the trapped gases were analyzed to quantify the release of metals, if any.
How pyrolysis of PV modules can reduce the environmental impact?
Based study reported herein, we can suggest that, one can go with the pyrolysis of modules at 500 °C after removing the backsheet, followed by the pyrolysis gas passing through the water bubble to minimize the exhaust gas impact on the environment. Further the recycled glass may re-use for fabrication/lamination of new PV module.
Can pyrolysis technology be used to recycle PV modules and Eva?
As a proven environmental protection technology, a few studies have considered the application of pyrolysis technology to recycling PV modules and EVA, and most of them are limited to pyrolysis characteristics and product analysis, and there are few studies on EVA pyrolysis mechanism.
Can pyrolysis remove Eva from shredded PV panels?
Next, we examined a pyrolysis treatment of the shredded module with the backing removed by either chemical treatment or cryogenic treatment. Pyrolysis treatment of the PV panel allows for the complete removal of the EVA and therefore liberation of the cell and glass from the EVA.
What is the optimum pyrolysis temperature?
In order to gain an understanding of the physical pyrolysis process, mass balance experiments were carried out over the temperature range of 480–500 °C for samples V-EVA, UB and VB. This narrow temperature range was used due to a contrast of opinion on optimum pyrolysis temperature for EVA and PV backsheets published in literature 33, 59, 65.
