A solar house is a house that uses energy from solar radiation to replace part of conventional energy for heating, electricity generation, dehumidification, cooling and ventilation. Solar houses can effectively absorb and store solar heat in winter, prevent excessive solar radiation in summer, and dissipate indoor heat to the outside, thereby achieving the effect of keeping warm in winter and cool in summer.

Advantages and disadvantages of rooftop solar panels
It is not harmful to the human body d install solar panels on the roof.
Rooftop solar panels are devices that convert solar energy into electrical energy using photovoltaic power generation technology. The energy production process is based on the photoelectric effect, which converts energye photons in energy of. of electrons and involves no harmful emissions In terms of material emissions, compared to traditional methods of energy production, such as coal-fired power generation or nuclear power generation, power generation Solar energy does not produce harmful substances such as carbon dioxide, sulphide or radioactive waste. , and has no negative impact on the environment and human health.
How to judge if a house can be installed with solar panels? What are the precautions to take when installing solar panels in a house?
The advantages and disadvantages of Solar panels on the roof are as follows:
1. Advantages
1. Solar energy resources can be used efficiently to generate electricity and the electricity can be used. to be saved. Currently, the stategrants certain subsidies for the installation of electricity production 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 roof 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.illes. However, if it is cloudy or the sunshine is not particularly sufficient, power consumption will be affected. .
4. During installation, you need to drill holes in the roof and penetrate the roof. If the installation is not reasonable later, 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 are basically the same. Now crystalline silicon is used as an example to describe the photovoltaic power production process. P-type crystalline silicon is doped with phosphorus to obtain N-type silicon, formant a PN junction.
When light shines on the surface of the solar cell, some 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. on both sides of the PN junction. The agglomeration creates 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 provide people with abundant solar energy and enough energy for their daily lives. Therefore, many people want to install solar energy on their homes. So how to judge whether the house can be. installed? Solar panels ? If you want to make sureer that your house can be installed with solar panels, you also need to know what are the precautions to take to install solar panels in your house?
1. if your house can be installed with solar panels
House property It must be clear, the roof area and surrounding environment are feasible, provide a valid ID card, the angle of roof slope is moderate and sign a letter of commitment.
2. What are the precautions to take when installing solar panels in a house?
1. Solar water heaters are installed outdoors, so the water heater and roof must be installed securely so that they can withstand high winds.
2. During the northern winter, water heater pipes must be insulated and frost-proof to prevent water pipes from freezing and cracking.
3. The water heater must be designed and installed by the manufactureror a professional installation team.
4. Most water tanks are designed as pressure-free structures. The overflow port and exhaust port at the top of the water tank must not be blocked, otherwise the water tank will break due to excess water. pressure in the water tank. If the tap water pressure is relatively high, close the valve when filling the water, otherwise the water tank will burst because you will not have time to release the water.
5. The temperature of the solar water heater vacuum tube can reach more than 200℃ when exposed to air. It is not possible to fill the water for the first time or when it is difficult to determine whether. there is water in the tube. Do not fill the water under the scorching sun, otherwise the glass tube will be damaged if broken, it is better to fill it with water early in the morning or evening or after covering the collector during. ahour.
6. The water temperature of the vacuum tube water heater of the solar water heater can reach 70℃~90℃, and the maximum temperature of the flat water heater can reach 60℃~70℃ when bathing. , hot and cold water should be adjusted first into cold water and then into hot water, to avoid scalding.
7. Check once a year if the water tank is leaking, if the collector is damaged, if the parts are aging, if the bracket is rusty, etc. If problems are found, they should be replaced. and repaired on time. It is best to have them installed and maintained by a professional.
How to judge if a house can be installed with solar panels? The structure and construction conditions of each house are different, which also determines whether they can be installed with solar panels. What precautions should be taken when installing solar panels on a house? During theinstalling solar panels, you also need to choose the right installation location to ensure that solar energy can be absorbed and used to the maximum extent.
