Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically a photovoltaic support for concrete roofs. Background Technology

[0002] The advent of photovoltaic panels has brought solar energy utilization to a new level. In particular, with the increasing emphasis on sustainable development in recent years, the attention given to solar energy utilization technology has also risen. Solar energy conversion efficiency is a reflection of photovoltaic panel technology. The higher the solar energy conversion efficiency, the more popular photovoltaic panels are with users.
