Solar energy is inexhaustible, clean, pollution-free, renewable energy, it is the most important new energy in the 21st century.

With the continuous development of solar energy technology, solar street lights are becoming more and more common in our life. We can see them on the main and secondary roads, residential areas, factories, tourist attractions, parking lots, and other places in the city. So how does the solar street light change the solar energy into electric energy, so that the lamp can illuminate? What parts does it contain? Now let’s have a detailed understanding.

Solar power generation is a technology that uses the solar effect of semiconductor interface to directly convert light energy into electric energy. The key component of this technology is solar cells. After the solar cells are packaged in series, a large area of solar panels can be formed, and then with the power controller and other components, the solar power generation system is formed.

The main components of a solar power generation system include solar panel, battery, controller, inverter, and tracking system

Many RV players have come to a conclusion through long-term experience: the electricity on the RV is less and less sufficient. It’s true that today, with the development of science and technology, when we travel, we will carry a lot of electronic equipment in the car, which leads to more and more places using electricity. Lack of electricity has become a pain point for many RV players. In order to solve this problem, more and more RV manufacturers begin to incorporate the solar charging system into the selection column of car purchases, which also attracts many potential buyers of RV. How to choose solar panels? How much power is suitable to install? Today, let’s talk about the solar panel of RV.

The maximum power of solar panel Pmax = open circuit voltage × Short circuit current, which is their ideal power, and usually, we measure the solar panel as the rated power PM. In practice, the rated power is less than the maximum power, mainly because the output efficiency U of solar panels is only about 70%. In use, due to the different light intensity, the power at different times is also different. According to the experimental data, its actual average power P = 0.7pm.

If the solar panel is to drive the load directly and make the load work stably for a long time, the rated power of the load is PR = 0.7pm. If the power of the solar panel is selected according to the power of the load, the power of the solar panel is PM = 1.43pr. That is to say, the power of the solar panel should be 1.43 times the load power.

The junction box is a connector between the solar array and the charging control device, it is an important part of the solar panel. It is a cross-domain comprehensive design combining electrical design, mechanical design, and material science. It provides users with a combination connection scheme of solar panels.

As a kind of solar panel connector, the main function of the solar photovoltaic junction box is to export the power generated by the solar cell module through the cable. Due to the particularity of the use of solar cells and their expensive value, the solar photovoltaic junction box must be specially designed to meet the requirements of the use of solar panels.

The solar panels you purchased have finally arrived, and the engineer is going to install them. You are so looking forward to generating enough electricity every day after the installation so that you can benefit from them. But do you know what matters need attention in the installation process of the solar panels? These matters are very important. If they are ignored, the power generation of the whole solar system will be affected.

People have been trying to harness the energy of the solar until 1839, when Edmond Becquerel, a French physicist, invented photovoltaic cells. This enables people to use solar energy more. Since then, solar photovoltaic technology began a long development.

So, when using solar panels, have you ever thought about how they work?

The energy shortage problem has attracted more and more attention from us. And we pay more and more attention to the development and use of new energy. Solar energy is a kind of inexhaustible renewable energy. It has become one of the key development energies of new energy use.

In recent years, solar energy has played an important role in our lives. But do you know how many applications the solar panel has? Here we share all of them with you.

With the development and progress of society, people put forward higher and higher requirements for energy. We must look for energy that can ensure long-term enough supply and will not cause environmental pollution. Solar energy is the most ideal new energy.

Solar panels are designed to have a service life of 25 years, but there are still various problems in the production process that lead to short service life. Here are the 19 most common problems and their analysis, and how to avoid them.
