The price of environmental monitoring instruments for photovoltaic (PV) projects depends primarily on the monitoring parameters and configuration level

Prices for PV project environmental monitoring instruments range from 6,800 to 9,800 yuan, depending on the number of monitoring parameters and equipment configuration. Basic models monitor three core parameters: temperature, humidity, wind speed, and solar radiation. Standard and high-end research models can monitor more than ten meteorological data points, meeting the operation and maintenance needs of different PV power plants.

The price of PV project environmental monitoring instruments has always been a major concern in PV power plant investment and operation and maintenance. Currently, the price of mainstream PV environmental monitoring instruments is not fixed but rather varies in tiers depending on the model, configuration, and monitoring parameters.

From the perspective of monitoring parameters, basic environmental monitoring instruments typically only monitor three core parameters: temperature, humidity, wind speed, and solar radiation. These devices have a simple structure and are easy to operate, mainly suitable for small-scale distributed PV projects and rooftop PV systems, with prices ranging from 6,800 to 8,800 yuan. Taking the FT-WQX8B as an example, this eight-element micro-meteorological instrument integrates wind speed, wind direction, temperature, humidity, air pressure, total thermoelectric radiation, daily cumulative total radiation, and module temperature into one unit, with a reference price of 6800 yuan.

Standard photovoltaic environmental monitoring instruments add more monitoring dimensions to the basic model. The FT-FGF11, as a standard distributed photovoltaic weather station, has a reference price of 7800 yuan and can monitor multiple indicators such as solar radiation, ambient temperature and humidity, wind speed and direction. The FT-WQX10C adopts an integrated structural design and can collect and analyze more than ten types of meteorological data for photovoltaic areas, including ambient temperature, ambient humidity, atmospheric pressure, wind speed, wind direction, total thermoelectric radiation, and daily, monthly, and annual cumulative total radiation, with a reference price of 8800 yuan.

For photovoltaic power plants with higher precision and more comprehensive monitoring needs, the high-end research models offer more options. The FT-FGF11H is solar-powered and monitors parameters including wind speed, wind direction, temperature, humidity, air pressure, total thermal radiation, sunshine duration, and photovoltaic module temperature. Its reference price is 9800 yuan. This model meets national standards and complies with the latest data requirements and logical correspondences reported by the provincial dispatch center for photovoltaic power plants. It also supports secondary upgrades for new parameters.

Besides the hardware configuration of the equipment itself, the final purchase price of environmental monitoring instruments for photovoltaic projects is also affected by factors such as power supply method, data transmission protocol, mounting bracket type, and whether it is connected to a monitoring system. Mains-powered models are generally cheaper than solar-powered models, while equipment with RS485 MODBUS RTU protocol output and support for remote data transmission is relatively more expensive. Some high-end or customized equipment can cost over 20,000 yuan. When purchasing environmental monitoring instruments, photovoltaic power plant investors should comprehensively evaluate the power plant scale, monitoring accuracy requirements, and budget to choose the configuration most suitable for their project.
