The performance of an efficient solar domestic water heater based on an experimental study

Abstract

Urbanization, population and economic growth are nowadays among the major factors influencing the energy bill. This influence consequently leads to serious worldwide climate change. In the Moroccan context, this has pushed the country to a wise policy approach that allows it to increase the share of renewable energy, especially from solar and wind resources to improve energy efficiency. Approximately 93% of water is used for hygiene and cleaning, which consumes a lot of energy to heat it. In this context, a Flat Plate Collector (FPC) system is considered one of the most effective technologies since it is based on clean energy. Many people are in need for a FPC for domestic use. However, they can’t afford buying because it is expensive. The aim of this work is essentially to study and realize a locally made prototype which adopts welding technique and uses “Latin” in order to reduce costs and make it affordable for many people due to its low price. This technique is cheaper than what is in the local market. To achieve the ultimate goal of this study, a modulating and interpretation of the results were done followed by a simulation using MATLAB software. Photothermal conversion was studied using a heat transfer fluid (water) whose temperature could reach up to 65°C through flat plate collector.
