Photovoltaic roofs, as an important form of combining green energy with buildings, have been widely used in recent years. However, the particularity of photovoltaic roofs also brings many challenges, especially in terms of waterproofing, load, and fire prevention. This article will deeply analyze the pain points of photovoltaic roofs and explore how TPO waterproof membrane composite roof tiles can effectively deal with these problems.
1. Six major pain points of photovoltaic roofs
1. Waterproofing and leakage problems
Pain point: The installation of photovoltaic brackets requires drilling and fixing, which may damage the original waterproof layer and cause leakage risks.
Impact: Leakage will corrode the steel structure, affect the operation of the photovoltaic system, and even cause a fire.
2. Load and structural safety issues
Pain point: The self-weight of the photovoltaic system and the wind and snow load increase the burden on the roof, which may exceed the design bearing capacity.
Impact: The structural strength of the roof of old buildings is insufficient, and there are safety hazards in installing photovoltaic systems.
3. Fire safety issues
Pain point: Photovoltaic modules may cause fires under high temperature, electric arc, etc., and the fire protection level of traditional roofing materials is insufficient.
Impact: High fire risk, which may cause significant economic losses.
4. Heat island effect and material aging
Pain point: The temperature on the back of the photovoltaic panel can reach above 80℃, and the heat is transferred to the roof, accelerating the aging of the material.
Impact: High temperature environment reduces the power generation efficiency of photovoltaic modules and affects the system benefits.
5. Operation and maintenance problems
Pain point: Photovoltaic panels block the roof, and the waterproof layer or equipment needs to be disassembled for maintenance, which is complicated.
Impact: There are many safety hazards in high-altitude operations and the maintenance cost is high.
6. System integration and compatibility issues
Pain point: Photovoltaic systems and roof design belong to different professions and lack coordination, resulting in installation difficulties.
Impact: The roofing material and photovoltaic bracket are not compatible, affecting the stability of the system.
