The solar controller is a device placed between the solar panel and the battery pack to control the electric energy generated by the solar panel entering the battery. The main function is to ensure that the battery is properly charged and prevent overcharging. There is no better pwm or mppt solar controller, and the choice depends on personal needs.

If the maximum output voltage of the measured solar panel is 9V, this voltage is called open circuit voltage, which will change with the change of light intensity.

Working principle of solar panel

Solar panel is a power generation device that converts light energy into electric energy. Although the working efficiency of solar panel made of current technology and materials is still relatively low, it is still very beneficial for such clean and energy utilization without subsequent cost input. It uses photovoltaic effect or photochemical effect to realize the conversion of light and electric energy, and its main manufacturing material is silicon.

With the growth of global population and the rapid development of economy and society, the demand for energy is also increasing day by day. Although traditional fossil energy still occupies the dominant position in the global energy structure, these energy sources will inevitably release a variety of pollutants and carbon dioxide greenhouse gases in the process of consumption, which will have a serious impact on the global ecological environment protection and the response to climate change.

Therefore, countries around the world are vigorously developing new energy technologies, such as wind power, solar energy, nuclear energy, geothermal energy Biomass energy, etc.

The sun not only gives us life, but also constantly transmits energy to us on earth. Can we convert this energy into electrical energy to supply power for our electrical equipment? To achieve this goal, we need to use the device of solar panel.

Solar panel, also known as solar panel, is a device that converts solar radiation energy directly or indirectly into electric energy through photoelectric effect or photochemical effect by absorbing sunlight. With it, we can provide clean and quiet electric energy for the RV. When the sun comes out, we can charge the battery.

The term photovoltaic power generation will be familiar to you. In short, it is a new power generation system that uses the photovoltaic effect of solar cell semiconductor materials to convert solar energy into electric energy.

As an inexhaustible and clean energy, solar energy facilitates human life through solar water heaters, solar street lamps, solar power stations and other forms.

With the rapid development of new energy vehicles in recent years, can solar panels be used for the endurance supply of new energy vehicles?

Why should solar panels be protected by frames?

The solar frame plays the role of protecting solar modules and facilitating the connection and fixation of solar modules. Because solar panels are mainly composed of monocrystalline silicon or polycrystalline silicon solar cells and tempered glass, they are particularly brittle and easy to break, so they must be protected by a frame outside.

Composition of solar power generation system

The application of solar system to RV is not only a charging system, but also a small energy storage system. This system is composed of solar photovoltaic modules, solar charging controller and the battery you need. The most common length of solar panels is about 1 m2, and the power varies from 100W to 400W. This solar module is used to receive sunlight and is usually placed on the roof.

Many touring car players come to the conclusion that the electricity on the touring car is less and less sufficient through long-term experience. Yes, because with the development of science and technology, when we travel, we will carry a lot of electronic equipment in the car, resulting in more and more places using electricity. Not enough electricity has become a pain point for many RV players.

In order to solve this problem, more and more RV manufacturers have begun to include solar charging system into the optional column of car purchase, which has also attracted many potential buyers of RV. How to choose solar panels? How high-power solar panels are suitable for installation? Today, let’s talk about the solar panels of RV.

Automatic spool mounting tin coated copper strip

PV welding strip is an important part of every mainstream solar panel, which is used to interconnect solar cells and provide connection with junction box. PV welding strip is tinned copper strip, with a width of 1-6mm, a thickness of 0.08-0.5mm and a thickness of 10-30 μ M thick flux coating.

There are two forms of PV welding strip applied to photovoltaic modules: interconnection strip or bus bar and PV bus bar. In typical silicon solar cells, both are needed.
