Description

Photovoltaic power generation is a technology that directly converts sunlight into electrical energy using the photovoltaic effect at the semiconductor interface. With the goal of high-quality development set by the country, there has been a significant push for the application of clean energy. Solar energy, with its wide and inexhaustible resource distribution, aligns with the policy shift towards new types of energy in the country. In 2022, China's installed capacity of solar photovoltaic power increased by 57% compared to the previous year, reaching a historic high. The solar photovoltaic power generation capacity reached 96.6 GW, accounting for 42% of the world's total.

2. Customer Challenges：

①Due to the rotation of the earth, the illumination changes with the seasons and daily times. Compared with the illumination at a fixed location, it is necessary to keep the illumination angle of the solar panel facing the sun in real time to ensure the best power generation efficiency.

②Photovoltaic power plants basically lay out photovoltaic power generation units on a large scale. Relying on traditional manual inspection methods is a huge undertaking and requires equipment that saves more manpower and material resources.

③The equipment installation environment is relatively complex. When encountering extreme weather disturbances, a smarter method of early detection and early warning is needed.

Unable to track sunlight in real time          Traditional inspection workload is heavy         Need early detection

3. WITMOTION Solution

Solar photovoltaic power generation equipment includes multiple subsystems such as photovoltaic conversion, bracket structure, tracking control, and power storage. The WITMOTION Solar Inclination Sensing Tracking System allows the panel to face the sun at all times and allows light to illuminate the panel vertically at any time. The system device is significantly Improve the power generation efficiency of photovoltaic modules.

Combined with the sun tracking control algorithm, it adopts time control + inclination sensor closed-loop control, without angle accumulation error. The sensor is installed at the center of the back bracket of the solar panel and runs synchronously with the power generation panel to achieve high-precision and reliable heading and inclination tracking and attitude control. , allowing the panels to face the sun at all times, significantly improving the power generation efficiency of photovoltaic modules. Synchronous sensors can transmit the attitude data of each solar power panel to the management platform in real time, enabling early detection and early warning of faults, saving unnecessary manpower and material resources.
