Photovoltaic Weather Station

Product Introduction:

Meteorological environmental data is an important indicator for determining solar power generation, and plays a decisive role in the quality of solar power generation; it also provides effective data guarantee for the design of solar power stations. The photovoltaic environment monitor is a standard environmental monitoring station designed and produced in accordance with the meteorological observation standards of the International Meteorological Organization WMO and the IEC (International Electrotechnical Commission) specifications. The equipment meets the national standards and meets the latest data requirements and logical correspondence of the photovoltaic power station reported to the province. It has the characteristics of stable performance, high detection accuracy, and unattended operation, which can meet the business requirements of professional photovoltaic environment observation.

Functional features:

1. Collector: It adopts industrial-grade processing chip and ABS shell, which is light, sturdy and beautiful as a whole. It has a 192*64 full-dot LCD display, which can complete graphic display or 12*4 Chinese character display (optional 7-inch LCD display screen), suitable for various harsh environments.

2. Fully automatic tracker: The tracking methods of the fully automatic solar tracker include sensor tracking method and solar trajectory tracking method. The sensor tracking method is to sample in real time through the photoelectric converter, calculate and analyze the changes in the intensity of the sun, and then drive the mechanical mechanism to achieve solar tracking. Make the direct radiation tracking measurement more accurate.

3. Sensors: various meteorological element sensors such as ambient temperature, humidity, wind speed, wind direction, air pressure, component temperature, direct radiation sensor, scattered radiation sensor, total radiation sensor, sunshine hours, etc. (optional according to needs). 

4. With external USB storage expansion function. 

5. Bracket: The surface of the main pole is treated with hot-dip galvanizing and electrostatic spraying, which has strong corrosion resistance and oxidation resistance. 

6. 1 set of meteorological data analysis platform:

Data query function: support query, export and print functions of various real-time data and historical data in any time period.

Data statistics function: support single element statistics function: statistics of single element maximum, minimum and average values can be performed by year, month, day, hour, 10 minutes or any time period.

Data chart function: A real-time curve can be formed based on the collected data, and can be presented in an intuitive way such as a bar chart or pie chart.
