The impact of photovoltaic power generation on the roof is: the installation of photovoltaic panels will cause damage to the roof, and the installation of photovoltaics on the roof will also increase the burden on the roof. The installation of photovoltaic panels will affect the insulation effect of the roof. .
First of all, the installation of photovoltaic panels can cause damage to the roof. Because photovoltaic panels need to be drilled and fixed, they will leave large and small holes on the roof, which will affect the waterproofing and maintenance of the roof.
Secondly, installing photovoltaics on the roof will also increase the burden on the roof. Photovoltaic panels not only have their own weight, but also exert greater pressure on the roof under the action of wind, increasing the burden on the roof and easily leading to problems such as roof leakage and cracking.
In addition, the installation of photovoltaic panels will also affect the insulation effect of the roof. Photovoltaic panels block part of the sunlight, reducing the insulation effect of the roof, thereby increasing the difficulty and cost of roof maintenance.
Advantages of photovoltaic power generation
1. Energy independence: Most people have always relied on the national grid to provide them with electricity services. When the power grid is out for an extended period of time, there is a sense of helplessness.
If you have a solar system with energy storage, you can continue to generate electricity during emergencies. If you live in a place where the power grid is unreliable, or are often threatened by severe weather such as typhoons, then this kind of energy storage system is very necessary.
Public power also limits those who want to live off the grid, such as in remote mountainous areas. Solar energy can generate electricity in places where power lines are difficult to carry. Generating electricity completely autonomously is liberating. And as the cost of electricity rises, the use of lower-cost renewable resources in the coming decades will also make low-carbon living a reality.
2. Save electricity bills: With a photovoltaic power generation system, you can reduce electricity bills or convert the generated electricity into monthly fixed income. Even if you use a loan to install a distributed photovoltaic power generation system, although the investment payback period is extended, you can still enjoy visible benefits from solar power generation from the moment the photovoltaic system is connected to the grid for power generation.
