Experimental dataset for the thermal performance of a low-cost serpentine CPVC solar water heater under high-Andean climatic conditions

<p dir="ltr">This dataset contains the experimental and meteorological data supporting the study “Experimental thermal performance of a low-cost solar water heater with a serpentine CPVC collector under high-Andean climatic conditions: A case study.” The experiments were conducted in Chachapoyas, Amazonas, Peru, over 30 consecutive days from February 10 to March 12, 2023. The dataset includes temperature measurements from four DS18B20 sensors located at the cold-water inlet, midpoint of the CPVC collector, hot-water outlet, and storage tank; solar radiation and daily solar energy data; ambient temperature and precipitation records; and data used to estimate daily thermal efficiency under daytime-use, nighttime-use, and no-use operating conditions.

The files also contain the data used for the statistical analyses and figures reported in the manuscript.</p>
