Active solar still with solar concentrating systems, Review

Abstract

Clean water is quickly decreasing as the necessity for it rises year after year. Desalination of seawater is the only means to remedy this problem. The scientific community has focused on solar powered salty water desalination devices as a clean alternative throughout the last few decades. Solar stills convert solar energy into the heat required to generate clean water through the evaporation and condensation processes. The two very popular varieties of solar stills are active, and passive based on the heat source to evaporate the basin water, which can be either directly through the sun or indirectly using external heat sources such as concentrating collectors which are coupled with desalination units. This article provides an exhaustive analysis of active solar stills’ advancement with solar concentrating systems and techniques for improving performance, desalinated water production, efficiency, and maximum output. This work intends to keep researchers and the scientific community informed about developments in active solar stills equipped with solar concentrators.

Thermal Stress Mechanism of Thermochemical Reactor of 5 kW Solar Simulator with Temperature Distribution as the Load Condition

“…In concentrated solar thermal technology, the incident solar energy is reflected by the reflector and focused on the solar receiver, where it is converted into thermal energy [4][5][6]. This thermal energy is supplied to the cavity for thermochemical reactions [7][8][9][10][11].…”
