What is photovoltaic?

Photovoltaic industry, PV for short. 76% of China’s land has abundant light and the distribution of light energy resources is relatively uniform; Compared with hydropower, wind power, and nuclear power, solar power generation has no emission and noise, mature application technology, safety, and reliability.

In addition to large-scale grid-connected power generation and off-grid applications, solar energy can also be stored by pumping, superconductivity, storage battery, hydrogen production, and other ways.

1. Solar power generation uses the natural energy of the sun to generate electricity. Specifically, solar panels capture certain wavelengths of solar radiation and convert it into electricity for homes, calculators, etc.

2. Photovoltaic cells in solar panels cause the reaction between photons and electrons on the atomic scale. When photons (light) collide with electrons, electrons bounce up. The electrons are then captured and directed into available electricity.

“Photovoltaic + agricultural greenhouse” is a hot rural income generation model at present. Maybe you just listen to us: photovoltaic agricultural greenhouse, don’t know what’s going on. So what are the advantages and types of the photovoltaic greenhouse? How are the benefits? Now let’s learn about it.

Type of photovoltaic greenhouse

The technical experts and agricultural experts who designed the greenhouse told us that the crops suitable for different shed types are different. In combination with the differences in geographical environment, the crops will be different. At present, there are more than 20 shed types for 5 generations, among which the common photovoltaic shed types and planting types are as follows:

Many times, we see that the solar street lamp is not on at the roadside. What happened? In addition to life expiration, the following reasons will also cause solar street lamp does not work.

The solar panel is damaged. If the solar panel is damaged, there will be no electric energy storage in the whole solar street lamp system, resulting in no energy supply for the solar street lamp. At night, the solar street lamp does not light because there is no electric energy supply.

The working environment of solar panels is different, and the requirements for the adaptability and weather resistance of solar panels are very strict, which requires solar panel manufacturers to control the quality when selecting raw materials. In all raw materials, the importance of junction boxes is very prominent.

As an important component of solar panels, the solar photovoltaic junction box is a connector between the solar cell array composed of solar panels and the solar charging control device. It is a cross-domain comprehensive design integrating electrical design, mechanical design, and material science, which provides users with a combined connection scheme of solar panels.

1. Selection of construction site

Inspect the construction site and surrounding environment to ensure the feasibility of project implementation.

There shall be no shelter around the installation site to ensure the normal daylighting of solar panels. If it is difficult to ensure that there is no shelter all day, try to ensure that there is no shelter between 9:00 a.m. and 15:00 p.m.

Household photovoltaic system generally includes ① solar panel, ② lightning protection box, ③ cable, ④ grid-connected inverter, ⑤ metering instrument. But for the general public, how to build a suitable distributed photovoltaic grid-connected power generation system?

Which places are suitable for installing distributed photovoltaic power generation systems?

1. Workshop in industrial field: especially in factories with large power consumption and expensive online purchase price, the workshop usually has a large roof area and an open and flat roof, which is suitable for the installation of photovoltaic arrays; Moreover, due to the large power load, the distributed photovoltaic grid-connected system can achieve local consumption and offset part of the online purchase power, so as to save users’ electricity charges.

Are you curious: Where does the electricity around us come from? How does electric energy come out? What are the advantages and disadvantages of each power generation method? Next, let’s introduce the mysteries of each power generation mode.

In recent years, with the large-scale construction of photovoltaic power stations, there have been varying degrees of quality and safety hazards. Safety and quality have become the number one killer of long-term stable power generation of photovoltaic power stations.

Once there is a serious accident such as an aircraft explosion or even a fire, it will not only affect the power generation but also have a very bad impact on national property and even human life.
