This solar research site is located in the Tabernas Desert, 30 km from Almeria and is a perfect location to challenge our DustIQ to a dusty environment.<\/p><p>This desert is also the stage for some well-known films; scenes of the westerns of Sergio Leone (the Good, the Bad and the Ugly), Indiana Jones and Conan the Barbarian were recorded here. This harsh environment provides a good test location for the DustIQ. The site receives a direct annual insolation of over 2100 kWh\/m2 and the average annual temperature is around 17\u00b0C.<\/p><p><a href=\"http:\/\/www.psa.es\/en\/\">PSA<\/a> is the largest research, development and test centre in Europe dedicated to concentrated solar energy and belongs to CIEMAT (the Spanish Centre of Energy, Environmental and Technology Research). At PSA, CIEMAT and DLR (German Aerospace Center) work closely together to evaluate solar power technologies. The PSA research centre is fully equipped with a unique network with over 10 automatic solar trackers with pyrheliometers and over 50 pyranometers distributed within approximately 1 km\u00b2 and you will find many Kipp &amp; Zonen instruments around their facilities.<\/p><p>When I arrived at the site, I was welcomed by Dr. Stefan Wilbert from DLR and Sergio Gonzales from CIEMAT. They work on radiation measurements, nowcasting, data resources, soiling, and other topics.<\/p><p>They were excited to have a DustIQ at PSA because, although it is initially designed for photovoltaic solar energy plants, it also offers potential for concentrated solar thermal power applications. Soiling also has a significant impact on the performance of mirrors, reflectors and absorber tubes of heliostats and troughs.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8ef12cf elementor-widget elementor-widget-image\" data-id=\"8ef12cf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/plataforma_solar_de_Almeria.png\" data-elementor-open-lightbox=\"yes\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6MjMxNiwidXJsIjoiaHR0cHM6XC9cL2Jsb2cub3R0aHlkcm9tZXQuY29tXC93cC1jb250ZW50XC91cGxvYWRzXC8yMDIxXC8wMVwvcGxhdGFmb3JtYV9zb2xhcl9kZV9BbG1lcmlhLnBuZyJ9\">\n\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"750\" height=\"366\" src=\"https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/plataforma_solar_de_Almeria.png\" class=\"attachment-large size-large wp-image-2316\" alt=\"Platforma solar de Almeria\" srcset=\"https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/plataforma_solar_de_Almeria.png 750w, https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/plataforma_solar_de_Almeria-300x146.png 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-507b97e elementor-widget elementor-widget-text-editor\" data-id=\"507b97e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>Soiling measurements at PSA<\/h3><p>Currently, the Soiling Ratio at PSA is determined in several different ways:<\/p><ul><li>With 2 pyrheliometers on a Kipp &amp; Zonen 2AP sun tracker, where one looks directly at the sun, and the other looks at it through a mirror.

One DustIQ was mounted vertically on the side and the other one horizontally on top of the frame. The output of both DustIQs will be compared to the other soiling measurements on site.<\/p><p>Additionally, we have installed a CMP3 to measure the POA (plane of array) irradiance of this specific set up. The installation went smoothly and by the end of the day we were collecting measurements through a Campbell Scientific CR1000X data logger. Every 10 minutes data is sent directly to the Kipp &amp; Zonen FTP server at our headquarters in the Netherlands.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-831f285 elementor-widget elementor-widget-image\" data-id=\"831f285\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/different_solar_measurements-neu.jpg\" data-elementor-open-lightbox=\"yes\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6MjMyMCwidXJsIjoiaHR0cHM6XC9cL2Jsb2cub3R0aHlkcm9tZXQuY29tXC93cC1jb250ZW50XC91cGxvYWRzXC8yMDIxXC8wMVwvZGlmZmVyZW50X3NvbGFyX21lYXN1cmVtZW50cy1uZXUuanBnIn0%3D\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"750\" height=\"323\" src=\"https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/different_solar_measurements-neu.jpg\" class=\"attachment-large size-large wp-image-2320\" alt=\"Solar measurements\" srcset=\"https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/different_solar_measurements-neu.jpg 750w, https:\/\/blog.otthydromet.com\/wp-content\/uploads\/2021\/01\/different_solar_measurements-neu-300x129.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ed2d145 elementor-widget elementor-widget-text-editor\" data-id=\"ed2d145\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The scientists of DLR and CIEMAT will help us to perform the evaluation of the DustIQ\u2019s:<\/p><ul><li>We will decide in collaboration when the DustIQs are cleaned,<\/li><li>DLR will perform the local-dust calibration one or more times,<\/li><li>We will work together on the soiling data, and publish a paper about the performance.<\/li><\/ul><p><a href=\"https:\/\/pages.kippzonen.com\/DustIQ\">Subscribe to our DustIQ news feed<\/a>\u00a0to receive news and the test results in your mailbox.<\/p><h3>Dust samples to validate the calibration<\/h3><p>As standard, a DustIQ will be delivered calibrated for Arizona Test Dust. However, local dust may have a different colour and thus different scattering properties, which determines the signal strength as measured by the DustIQ. For the best performance of the DustIQ users should perform a field calibration, a simple procedure that takes 5 minutes and enables the DustIQ to determine the scattering properties of the soiling.<\/p><p>I\u2019ve collected local dust samples from the site and brought them back to Delft, where we will characterize the dust. We want to compare the scattering properties obtained by these two DustiQ\u2019s using their local-dust-calibration procedure with the values we can obtain in the lab.<\/p><p>At R&amp;D we are looking forward to further cooperation with DLR and PSA. More soiling studies are being planned, such as a \u2018desert test\u2019 where we will perform a comparison of pyranometers with and without ventilation, test the AirShield\u00ae DNI for pyrheliometers and the instruments of the RaZON+ for their resistance to soiling.<\/p><p>A big thank you to everybody at PSA, DLR and CIEMAT for your help and enthusiasm!<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1bccd15 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"1bccd15\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6aa8f3b elementor-widget elementor-widget-text-editor\" data-id=\"6aa8f3b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Written by \u00a0Joop Mes, Research &amp; Science Manager<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>I\u2019ve just returned from Spain where I installed a new test setup for DustIQ at Plataforma Solar de Almeria (PSA).
