Are you satisfied with your actual Solar generation? Let’s have a look on this.
Solar Photovoltaic System (SPV) is one of the growing green energy sources having immense penetration in the national grid as well as the off-grid around the globe. Regardless of different solar insolation level at various regions of the world, SPV performance is also affected by several factors: conversion efficiency of PV cell technology, ambient temperature and humidity, soiling and seasonal/weather patterns. Solar PV is expected to be one of the renewable energy sources having a 25% share in total energy demand as forecasted in the year 2050 by deploying more than 8,500GW capacity. The operation of the projected capacity of PV plants will be a challenging job, mostly regarding its reliable, economic, and sustainability.
In recent years, an increase in PV systems installed close to the equator line has occurred due to the higher irradiation afforded at these locations. Closer to the equator, the soiling effect becomes more decisive because of the lower tilt angle of the installed PV modules. The operation of the projected capacity of PV plants will be a challenging job, mostly regarding its reliable, economic, and sustainability. Atmospheric dust is likely to absorb the solar radiations which would otherwise hit on module surface whereas soiling is an issue caused by the deposition of dust and other opaque particles over the module surface. On long term perspective, soiling can result in degradation of the expected life of PV modules and seasonality in spectral response. According to a case study of 186 PV sites in USA, it has been observed that by cleaning a solar PV plant half the way of dry summer without rainfall, 0.81% to 4.7% improvement. Can be seen in energy harvest action throughout a year, and up to 9.8% by implementing an automated cleaning system. Here is a small curve regarding Soiling Loss for a curve of 30 days is shown below:
There is also another problem regarding degradation of actual solar power generation is Loose Connection. Faulty wire connection is the main reason behind this. Loose wiring can cause unexpected electrical issues. To correct wiring faults, Installers with electrical experience use meters and other tools to pinpoint problems. They can also disconnect faulty parts to keep them from damaging other sections of Solar system.
