Photovoltaic meteorological station

Product Introduction:

Meteorological environmental data is an important indicator that determines the quality of solar power generation and plays a decisive role in it; At the same time, it also provides effective data assurance for the design of solar power plants. The photovoltaic environmental monitoring instrument is designed and produced in accordance with the meteorological observation standards of the International Meteorological Organization (WMO) and the IEC (International Electrotechnical Commission) standards. The equipment meets national standards and meets the latest data requirements and logical correspondence of the photovoltaic power plant submitted to the provincial survey. It has the characteristics of stable performance, high detection accuracy, and unmanned operation, which can meet the business requirements of professional photovoltaic environmental observation.

Functional features:

1. Collector: Equipped with industrial grade processing chips and ABS casing, it is lightweight, sturdy, and aesthetically pleasing overall. Equipped with a 192 * 64 full dot matrix LCD display, capable of displaying graphics or 12 * 4 Chinese characters (optional with a 7-inch LCD screen), suitable for various harsh environments.

2. Fully automatic tracker: The tracking methods of the fully automatic sun tracker include sensor tracking and sun trajectory tracking. The sensor tracking method is achieved by real-time sampling through photoelectric converters, calculating and analyzing changes in solar intensity, and driving mechanical mechanisms to achieve solar tracking. Make direct radiation tracking measurements 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. Equipped with external USB storage expansion function.

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

6. 1 set of meteorological data analysis platform:

Data query function: supports the query, export, and printing of various real-time and historical data for any time period.

Data statistics function: supports single element statistics function: can perform statistics on the maximum, minimum, and average values of a single element by year, month, day, hour, 10 minutes, or any time period.

Data chart function: Based on the collected data, real-time curves can be formed and presented in intuitive ways such as bar charts and pie charts.
