This paper presents and discusses the performance evaluation, monitoring and analysis of a Heating, Ventilation and Air Conditioning (HVAC) system in a residence in Saudi Arabia. The installed air conditioning (A/C) system operates in extreme and severe weather conditions. The local area is characterized by a high level of ambient temperature, high irradiation, high humidity and frequent dust storms...
In this paper, we introduce a detailed photovoltaic panel (PV) model that includes Bishop circuit representation for the hot spot phenomena. The hot spot phenomenon is considered as preliminary damage occurring in solar panels. The main reasons are shading and possibly dust accumulation. The hot spot reduces the output power of the panel and it life time. The developed model was based on Matlab /Simulink...
This paper presents an experimental investigation for the performance of a PV generator using Cassy System environment. Two PV panels were exposed to severe environmental conditions such as high temperature, high humidity, relatively high irradiation and frequently high levels of dust deposition. Each PV panel of 150 W rating was feeding a variable resistive load. The measurement was taken through...
