Product solution introduction and application

1. Scope of application of the scheme 
Distributed photovoltaic power generation refers to photovoltaic power generation facilities that are built and operated at or near the user's site, mainly for self-use on the user side, with excess electricity connected to the grid and balanced and regulated in the distribution network system. In order to ensure the normal operation and data analysis of photovoltaic power stations, it is usually necessary to equip distributed photovoltaic power generation environmental monitoring systems to monitor indicators such as total solar radiation, ambient temperature, wind speed and direction, and photovoltaic module temperature. The distributed photovoltaic power generation environmental monitoring system can be connected to the monitoring system, which displays, records and analyzes the data of the environmental monitoring system. It can also be connected to the inverter control system, and the control system analyzes the sensor data to ensure the effective operation of the photovoltaic power station.

2. Product Description

It adopts a new integrated high-integration design, and the overall weight and installation time are 30% of those of conventional weather stations. Ultrasonic wind direction and wind speed are used to replace mechanical sensors, which greatly reduces the repair caused by mechanical wear while improving accuracy. It adopts a high-stability solar total radiation sensor with perfect cosine characteristics, fast response, zero offset and wide temperature response performance to ensure accurate and stable radiation data. Our company has many years of rich experience in serving domestic and foreign photovoltaic power station users, with sufficient sensor inventory, complete production lines, mature instrument and equipment debugging technical capabilities, comprehensive after-sales tracking services, and fast logistics and transportation systems. (Note: The solar total radiation sensor can be equipped with imported sensors, with product-related certificates) 
III. Product implementation specifications 
The site selection of distributed photovoltaic power generation environmental monitoring systems needs to consider many factors, and the site should be established in a place that is not shaded from sunrise to sunset throughout the year. Based on international observation methods, national observation specifications, power industry standards and many years of rich experience in site selection and installation and commissioning of environmental monitoring systems, our company provides detailed and professional specification guidance documents to relevant personnel of photovoltaic power stations.
