Solar Keymark collector database and hourly yield model for eleven hot-climate sites in the Middle East and North Africa
Description
This dataset supports the article "Solar collector certification for hot climates: a critical review and an analysis of 46 Solar Keymark collectors at eleven sites in the Middle East and North Africa" (M. Elmnefi, submitted to Renewable and Sustainable Energy Reviews). This dataset supports the article "Solar collector certification for hot climates: a critical review and an analysis of 46 Solar Keymark collectors at eleven sites in the Middle East and North Africa" (M. Elmnefi, submitted to Renewable and Sustainable Energy Reviews). It contains (1) a database of 88 Solar Keymark certificates (62 independent tests) with ISO 9806 collector parameters, incidence-angle modifier tables, stagnation temperatures and certified gross thermal yields; (2) a results workbook with all results reported in the article, including model validation, rank correlations at eleven hot sites, the equivalent-temperature rule, stagnation exposure, a domestic hot water check, sensitivity analyses, bootstrap intervals and a Monte Carlo analysis of parameter uncertainty; (3) the hourly ISO 9806 yield model in Python; and (4) the PVGIS 5.3 typical meteorological year files (SARAH-3, 2005-2023) used for all sites. Certificate data originate from the public Solar Keymark database (https://solarkeymark.eu/database/); weather data from PVGIS, European Commission Joint Research Centre (https://re.jrc.ec.europa.eu/pvg_tools/).

Steps to reproduce
1.Certificate data: Solar Keymark datasheets (collector sub-scheme, status November 2026) were downloaded from https://solarkeymark.eu/database/. For each certificate, the ISO 9806 parameters (η0,b, a1, a2, Kd), incidence-angle modifier tables, stagnation temperature and certified gross thermal yields were transcribed into S1_Collector_database.xlsx. Certificates based on the same test report were treated as one test. 2.Weather data: PVGIS 5.3 typical meteorological years (SARAH-3, 2005–2023) were downloaded for each site from https://re.jrc.ec.europa.eu/pvg_tools/ (files in PVGIS_input_files.zip). 3.Yield calculation: run the hourly ISO 9806 model with Python 3 (numpy, pandas, scipy): python S3_yield_model.py S1_Collector_database.xlsx athens.csv wurzburg.csv riyadh.csv ... Collectors face the equator at the Solar Keymark tilt rule (latitude − 15°, rounded to 5°) and operate at constant mean fluid temperatures of 25, 50 and 75 °C. 4.Validation and analysis: modelled yields at Athens and Würzburg are compared with the certified yields; rankings at the hot sites are compared using Spearman rank correlation. All results, including sensitivity, bootstrap and Monte Carlo analyses, are in S2_Results_workbook.xlsx, with one sheet per analysis.
