Investigation effects of environmental and operating factors on PV panel efficiency using by multivariate linear regression

Abstract

The aim of this study is to show the investigation effects of environmental and operating factors on photovoltaic (PV) panel efficiency using by multivariate linear regression. Also in this study, the relationship between PV panel efficiency and some environmental and operating factors (solar radiation, opencircuit voltage, short circuit current (I sc), power, fill factor, outside temperature, humidity, wind speed, and voltage) were investigated using multivariate linear regression. The effect of binary parameter interactions on panel performance was investigated using the backward elimination (or deletion) method. The data used in the analysis were obtained from monocrystal and polycrystal panels in December in the winter season. In all analyzes, the regression values are close to 1, which indicates that the compatibility between binary parameters and performance characteristics is perfect. In addition, the three most effective parameters on panel efficiency were found to be solar radiation, maximum power (P max), and I sc , respectively.

Multi-criteria solar power plant siting problem solution using a GIS-Taguchi loss function based interval type-2 fuzzy approach: The case of Kars Province/Turkey

“…This leads to a decrease in the frictional force near the ground as well as a decrease in wind intensity and thus in the Coriolis force. This phenomenon reduces the overall movement of the atmosphere and wind generation [ 19 , 33 , 82 , 83 ]. Fig.…”

Inductor based I-V curve measurement method for photovoltaic panels

“…PV panels convert sunlight directly to electricity without environmental pollution and they require minimal maintenance. However, the energy efficiency of PV systems ranges between 8% and 20% [1]. The performance of photovoltaic panels is directly affected by the irradiance, temperature, electrical load and age of the panel.…”

Güneş Enerjisi Santrallerinde Yağmursuyu Hasadı

“…Güneş enerjisi santrallerinde performans, PV (fotovoltaik) modüllerinin dönüşüm verimliliği, meteorolojik etkiler, kirlilik, PV eğim açısı, PV hücre sıcaklığı gibi faktörlerden etkilenmektedir. Araştırmacıların panel verimini artıracak yönde çalışmalara odaklanmasının yanında çeşitli sebeplerle düşen panel verimliliğinin geri kazanılması da önemli bir araştırma konusu olarak karşımıza çıkmaktadır [23][24][25]. Bu çerçevede karşılaşılan en büyük problem PV panel camı üzerinde biriken toz ve partikül kirliliği olarak ifade edilebilir [26,27].…”
