About the introduction of solar panels

With the development of science and technology, many high-tech products appear in our lives, such as computers and air conditioners. Solar energy is a high-tech product. To put it bluntly, solar energy is the use of the sun's energy to heat water. Almost all of our homes are equipped with solar energy, because in this way, we can take a bath with solar energy. However, many people want to know the price of household solar panels. Today, I will introduce them to you in a small series. Everyone must listen carefully.

Household solar panels

1: The price of household solar panels is currently 10 yuan per watt, and there are many types, from tens of watts to more than 300 watts. Install according to your household electricity. Affected by the international market this year, the price of solar panels has fallen to historical highs. Now is a good time to buy. http://dghoppt.com/products-2138616.html

2. If you want to use the panel to generate electricity and heat, it is theoretically possible. However, due to the short sunshine time in winter and other reasons, the power generation may not be particularly large, requiring more panels, which is very costly and is affected by various aspects such as storage batteries. Personal feeling is not particularly reliable. Although the panel is a low-carbon and environmentally friendly product, it will take some time for this product to be commercialized in China due to the price. Italy and Germany are the countries with the most panels installed in the world.

The composition of the solar power system

The solar power generation system is composed of solar cells, solar controllers and storage batteries. If the output power is AC 220V or 110V, you need to configure an inverter. The function of each part is:

(1) Solar panel: The solar panel is the core part of the solar power system, and it is also a valuable part of the solar power system. Its function is to convert the sun's radiation capacity into electric energy, or send it to the storage battery, or drive the load to work.

(2) Solar controller: The function of the solar controller is to control the working status of the entire system and protect the battery from being overcharged and over-discharged. In places with large temperature differences, a qualified controller should also have temperature compensation. Other additional functions of the controller, such as light control switch and time control switch, should be optional.

(3) Batteries: generally lead-acid batteries. In small and micro systems, nickel-metal hydride batteries, nickel-cadmium batteries or lithium batteries can also be used. Its function is to store the electricity generated by solar panels when there is light, and then release it when needed.

Inverter: The direct output of solar energy is generally 12V DC, 24V DC, 48V DC. In order to provide electrical energy to 220V AC equipment, the DC energy generated by the solar power generation system needs to be converted into AC power, so a DC-AC inverter is required.

The above is the price of household solar panels introduced by Bian Xiao. The price of different watts is different. You can refer to the price introduced by Bian Xiao. In addition, Bian Xiao wants to tell everyone here that using solar energy in summer may be good for us, but in winter, the sunshine time is very short, so if we take a bath, the water will not be too hot. So choose according to your own situation. This concludes Bian Xiao’s introduction, and I hope it will be helpful to everyone.
