Description

Photovoltaic module Technical Field The invention belongs to the field of photovoltaic power generation, and particularly relates to a photovoltaic module. Background Since the photovoltaic module has a service life cycle (typically 15-25 years), with the rapid development of the installed market of photovoltaic modules in recent decades, it is expected that the recycling problem of a large amount of waste photovoltaic modules will be faced in the next 10-15 years. Because the most typical photovoltaic module still adopts glass packaging photovoltaic module (simply referred to as glass photovoltaic module) at present, because glass weight is heavy, and is the biggest part of proportion among the photovoltaic module, the prior art is to dismantling the method of old and useless glass photovoltaic module all with loaded down with trivial details, with high costs, then carry out recycle to the various materials of old and useless glass photovoltaic module, recycle efficiency is still comparatively lower.
