What are the effects of installing solar panels on a house?

The impact of roof solar panels is mainly due to the high installation cost and economic burden. Long-term wind and sun exposure on the roof may cause corrosion. Electricity consumption will be affected when it is cloudy. Punching holes in the roof during installation may cause roof leakage.

Damage to the roof structure. Solar photovoltaic power generation relies on the volt effect generated by the semiconductors inside the solar panels. If the roof structure is not reinforced at the beginning of the design. Since the photovoltaic power generation equipment itself is very heavy, it may damage the roof structure, especially if it is an old house, it is very likely to damage the roof.

Destroy the waterproof layer on the roof. The bracket for installing the photovoltaic power generation system needs to be drilled on the roof first. After drilling, the original waterproof layer of the house will be damaged. If the waterproof layer is not redone, water will leak when it rains. Due to the gap between the screws and the holes, the waterproof process is very demanding. If it is too thick, it will affect the installation. Too thin and ineffective. The effect of the second waterproofing is far less than that of the first time, which will increase the possibility of water leakage.

Light pollution problem. If there are relatively tall buildings near the installation of photovoltaic power generation equipment, it is likely to reflect part of the sunlight to the interior of nearby buildings, causing light pollution to the indoor environment. Relevant studies have shown that excessive light can lead to eye diseases, and even cause anxiety, fatigue, and decreased concentration in people's emotions.

Safety issues. If it encounters strong winds, the photovoltaic panel is likely to blow over. In particular, the installation of the panel is not firm or the screws are rusted and aged, the panel may be blown off by the wind, and the later maintenance cost is also higher.

What are the pros and cons of installing solar panels on roofs

advantage

Solar PV module power generation reduces electricity costs.

In foreign countries, solar power installation costs are largely or even completely offset. Instead of waiting to see savings increase, homeowners can directly feel a lighter wallet. In addition, excess unused solar energy can be stored in the grid.

Solar photovoltaic systems require very little maintenance.

Once the solar panel system is in place, perhaps just a few times a year to clean the panels, homeowners can rest assured that the solar panels will generate electricity every day (unless there are exceptional circumstances).

Disadvantage

Solar energy is not fixed.

Solar panels are not exposed to sunlight 24 hours a day, solar energy cannot be generated at night, and less electricity is generated in winter or in very cloudy and rainy weather.

Solar energy storage is expensive.

While the price of solar modules is falling, batteries and other ways of storing excess solar energy are still quite expensive (another reason to stay connected to the grid).

Need to occupy a certain space.

Generally, the power and area of a solar panel are related. The greater the power, the larger the area occupied.

Solar panel introduction

A solar cell, also known as a "solar chip" or "photovoltaic cell", is an optoelectronic semiconductor sheet that uses sunlight to directly generate electricity. A single solar cell cannot be used directly as a power source. For power supply, several single solar cells must be connected in series, parallel and tightly sealed into components.
