choose the best pyranometer - 1

Thermal Sensors Choose the best pyranometer Next level instruments in every class at the most attractive price level Hukseflux offers a wide range of solutions for measurement of solar radiation. This brochure offers you general guidelines for selection of the right instrument. The application of pyranometers in PV system performance monitoring according to IEC 61724-1 is highlighted as an example. Sensors specific for diffuse radiation and meteorological networks are also addressed in this selection guide. The right instrument for the application Choosing the right instrument for your application is not an easy task. We can offer assistance. But first, you should ask yourself the following questions: • are there standards for my application? • what level of accuracy do I need? • what will be the instrument maintenance level? • what are the interfacing possibilities? When discussing with Hukseflux, our recommendation for the best suited pyranometer will be based on: • recommended pyranometer class • recommended maintenance level • estimate of the measurement accuracy • recommended calibration policy • recommended interface Figure 1 SR30 pyranometers, our most popular solution for PV system performance monitoring according to IEC 61724-1 class A Accuracy improvement by a factor 2 Pyranometers are subject to classification according to ISO 9060. The 3 classes are: • secondary standard • first class • second class From second class to first class and from first class to secondary standard, the achievable accuracy improves by a factor 2. (see Figure 3) Hukseflux pyranometers Measurand ISO 9060 classification secondary standard, first class, second class Options Figure 2 Example of a Hukseflux pyranometer: SR25 secondary standard pyranometer with sapphire outer dome. This model is recommended for research grade diffuse radiation measurement. Output is either analogue millivolt or digital via Modbus RTU over RS485 and analogue 4-20 mA (current loop). hemispherical solar radiation analogue and / or digital output; with Recirculating Ventilation and Heating (RVH TM), sapphire outer dome, or use with VU01 ventilation unit; cable length; heaters and internal temperature sensors; various mounting and levelling fixtures Copyright by Hukseflux.

Thermal Sensors by Hukseflux, suppresses dew and frost deposition and is as effective as traditional ventilation systems, without the maintenance hassle and large footprint. • low power consumption: SR30 requires only 2 W, compared to 10 W for traditional ventilation systems low maintenance: SR30 does not require filter cleaning Figure 3 Frost and dew deposition: clear difference between a non-heated pyranometer (back) and SR30 with RVHTM technology (front) The dome of SR30 pyranometer is heated by ventilating the area between the inner and outer dome. RVH TM is much more efficient than...

leads to a higher measurement reliability. For lower class instruments, the relative loss of accuracy at a low maintenance level is less significant. At low maintenance intervals, although this is not formally complying with the IEC, ASTM and ISO standards, use of multiple low class instruments is a good alternative to using a single high class instrument. Table 1 gives an overview of pyranometers and the most common considerations for choosing a particular one. Interfacing We can assist you in optimising the interfacing of the pyranometer to the data collection platform at the measurement...
