Solar 3 Weather Station

The Weather MicroServer is the heart of this system. Sensors connect directly to it.

Solar 3 Weather Station offers required parameters with individual sensor options. The most cost-effective system, individual sensors can be located separately for optimal placement.

“We required your weather monitoring systems for the resource assessment and performance monitoring of our solar PV power plants... Columbia Weather Systems was able to provide us with a solution tailored to our specific requirements.”

Solar 3 Weather Station System Includes

  • Weather MicroServer with weatherproof enclosure
  • Air Temperature Sensor with radiation shield and 50-foot cable
  • Panel Temperature Sensor with 50-foot cable
  • Solar Radiation Sensor(s) with 50-foot cable (Click the Sensor tab to view solar radiation sensor options.)

Solar Radiation

Catalog No. 82605: This thermopile sensor meets ISO 9060 second class requirements. It measures solar radiation received by a plane surface, in W/m², from a 180° field of view angle. SR05 is ideal for general solar radiation measurements in meteorological networks and PV monitoring. The pyranometer is easy to mount and install, in particular with its ball leveling mechanism. The sensor outputs 0 to 1 VDC signal and can be interfaced directly to the Weather MicroServer’s analog channels.

ISO classification: ISO 9060 Second Class

SR05 Solar Radiation

Catalog No. 82603-6A: This thermopile sensor meets ISO 9060:1990 First Class requirements and features a sixty-four thermocouple junction (series connected) sensing element. The sensing element is coated with a highly stable carbon based non-organic coating, which delivers excellent spectral absorption and long term stability characteristics. It has improved performance due to the increased thermal mass and the double glass dome construction. The integral bubble level is raised to the top of the housing and can be viewed without removing the redesigned snap-on sun shield, which also covers the connector. The connector with gold-plated contacts allows for easy exchange and re-calibration.

The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets.

The sensor outputs 0 to 1 VDC signal and can be interfaced directly to the MicroServer’s analog channels.

ISO classification: ISO 9060:1990 First Class
Spectral range (20% point): 280 to 3000 nm
Spectral range (50% point): 285 to 2800 nm

Output: 0 to 1VDC

Includes 50-foot cable. Optional mounting brackets available.

KZ Pyranometer

Catalog No. 82603-10A: This thermopile sensor meets ISO 9060:1990 Secondary Standard requirements (highest possible ISO pyranometer performance category). The SMP10 extends this quality to applications where maintenance is difficult and/or forms a major part of the cost of ownership. The Internal drying cartridge is rated to 10 years if the housing is not opened.

The SMP10 uses a temperature compensated detector and has better linearity and long-term stability, lower thermal offset and faster response than a first class pyranometer.

The faster response time meets the requirements for solar energy monitoring.

ISO classification: ISO 9060 Secondary Standard
Spectral range (50% point): 285 to 2800 nm
Response time (63%): <0.7 s
Response time (95%): <2 s
