No.
Solar panels are installed on the roof for the production of photovoltaic energy. The entire electricity generation process consumes no materials, involves no mechanical rotation and emits no emissions, including carbon dioxide. The exhaust gases do not emit any waste water or residue and cause no pollution. Therefore, solar panels installed on the roof do not harm the human body. will not cause physical symptoms.
Rooftop solar panels are a way to harness the sun's energy and convert it into electricity to power a home or business. Before installation, several factors must be considered: type of roof, type of solar panel, installation method, installation location, etc.
Is it OK to install solar panels on the roof?
The advantages and disadvantages of solar panelss on the roof are as follows:
1. Advantages
1. Solar energy resources can be used efficiently to generate electricity and electricity can be saved. Currently, the state provides certain subsidies for the installation of electricity generation panels. Solar power generation can allow us to use less electricity and save on our families' electricity bills.
2. Installing solar panels on the roof is relatively simple, generally speaking, it can be installed by a few workers in half a day.
2. Disadvantages
1. The investment in installing solar panels is relatively large. For some families, installation fees may be considered and will not be accepted.
2. This type of solar power generation panel is installed directly on the tor if exposed to wind and sun for a long time, corrosion problems may occur.
3. After all, solar panels are obtained from solar energy, so they can only be used on sunny days. However, if it is cloudy or the sunshine is not particularly sufficient, power consumption will be affected. .
4. During installation, holes must be drilled on the roof to penetrate the roof. If the subsequent installation is unreasonable, the roof will leak.
The principle of solar panels
A solar cell is a device that responds to light and can convert light energy into electricity, producing an effect photovoltaic. many kinds of materials, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper selenium indium, etc. Their principles of energy production arebasically the same. Now crystalline silicon is used as an example to describe the photovoltaic power production process. Crystalline P-type silicon is doped with phosphorus to obtain N-type silicon, forming a PN junction.
When light irradiates the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to transition and become free electrons. accumulate on both sides of the PN junction to form a potential difference. When an external circuit is connected, under the action of this voltage, a current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting photon energy into electrical energy.
Solar panels can be installed on the roof, which is alsoent one of the most common installation methods today.
Rooftop installation can maximize the use of home space, avoid ground obstructions that block sunlight, and improve power generation efficiency.
However, before installation, factors such as the bearing capacity of the house, the weight of the solar panels and the installation method should be considered to ensure the safety of the installation.
In addition, local climatic conditions and environmental factors, such as wind speed, precipitation, etc., should be considered in order to select the appropriate solar panels and installation methods .
