Photovoltaic Solar Panel

Photovoltaic Solar panels are a type of panel that converts the radiant energy of sunlight into electricity. It consists of many solar cell modules, which can be connected in series or parallel to form a solar power system. Photovoltaic panels can be used in a variety of different applications, including residential, commercial, and industrial sectors.

The working principle of photovoltaic panels is based on the photogenerated effect. When the sun's rays hit the photovoltaic panels, the energy of the light activates the electrons in the photovoltaic panels, causing them to be released from the atomic orbitals and flow within the photovoltaic panels. This current is then captured by wires and can be effectively used in a variety of applications, such as rechargeable batteries and powering home appliances.

Solar panels convert solar energy into electricity, while DC motors convert electrical energy into mechanical energy. Therefore, it is theoretically possible for solar panels to drive DC motors directly. Specifically, solar panels convert solar energy into direct current and pass it through a converter, or inverter, into a direct current that can be used to drive a DC motor.

The first oil crisis in the 1970s prompted developed countries to increase policy support and capital investment in renewable energy, including solar energy. After entering the 21st century, developed countries such as Europe and America began to incorporate photovoltaic grid connected and off grid power generation systems into their development direction. At the same time, under the severe situation of energy substitution and the pressure of human ecological environment, and with the gradual improvement of laws, regulations and policies in various countries, the global photovoltaic industry is showing a rapid development trend.

In 2015, a large European listed photovoltaic solar energy company approached us through Google and provided us with a complete introduction to their projects and the future development trends of the industry. Our company has always been interested in the photovoltaic solar panel industry, but it's hard for us to imagine this product using an electric motor.

It is understood that solar panels are placed in open deserts, grasslands, or mountainous areas. Due to the different exposure times and directions of the sun, they need to absorb more sunlight. Therefore, it is necessary to install an omnidirectional light sensor or an omnidirectional sensor composed of multiple sensors to compare the light intensity in all directions. The main function of the motor is to control the rotation direction of the solar panel, ensuring that the solar panel can follow the strongest direction.

Due to the harsh environment in desert areas, the temperature of solar panels may reach 70 ° C or even not work, while the operating temperature of motors sometimes exceeds 100 ° C. So we must consider details such as the material and appearance size of the motor, and the cable conduit for the output must also be able to withstand sufficient high temperatures. Due to the large quantity, we also need to help customers save costs as much as possible.

In addition, under high temperature conditions, all raw materials should use insulation materials above 150 ℃. The insulation level of the motor is required to reach F level, while we have achieved H level.

The lubricating oil of the planetary reducer forms an oil film between the contact surfaces of various working parts of the reducer, reducing friction between the contact surfaces of the parts and taking away the heat generated in the transmission, so that the temperature of the parts is not too high, absorbing impact and vibration, reducing noise, and expelling impurities. We also use customized materials for bearings, and the lubricating oil temperature also reaches the required range of -35 ℃ to 100 ℃.

Due to the high power of the motor, the driver cannot be built-in into the motor. We suggest that customers customize external mini drivers directly, which can better save costs.

In addition, it is best to integrate the driver and motor, with a built-in driver. The motor must be completely sealed and have a protection level of IP65.

After various testing applications, we have successfully reached a cooperation agreement and the motor ultimately met the customer's requirements. We conducted large-scale procurement and ultimately obtained Mr. Faber's recognition.
