With the growing energy needs, a conscious effort has been made to use non-conventional
energy sources to generate clean energy efficiently. Solar energy has always been popular …

One popular simulation tool for predicting solar thermal (ST) performance is the F-chart
model, which has not been validated for the conditions in equatorial-climate countries. In this …

In this work, the optimization of a low temperature, water-in-glass, evacuated tubes solar
collector is presented. The process of optimization combined the simulated annealing …

The integration of evacuated tube receivers with non-imaging compound parabolic
concentrators (CPCs) operating in thermosyphon mode provides the opportunity to deliver …

The performance of solar thermal technology under high-altitude equatorial climatic and
solar path conditions has not been determined. Evacuated tube solar collectors are more …

This study addresses the challenge of optimizing flat-plate solar collector design,
traditionally reliant on trial-and-error and simplified engineering design methods. We …

The Andean Equatorial Region, due to its geographic location, shows great potential for
using solar energy. Solar thermal energy is of interest in the residential sector in Ecuador …

A solar radiation model is applied to a low temperature water-in-glass evacuated tubes solar
collector to predict its performance via computational fluid dynamics (CFD) numerical …

The most common natural flow water heating systems are in one-ended inclined pipes
today. This study aims to investigate the natural circulation solar energy system …
