RECONFIGURATION SOLUTION FOR EXTRACTING MAXIMUM POWER IN THE AGED SOLAR PV SYSTEMS

Photovoltaics (PV) is a simple method of harnessing the sun's energy by using solar cells which directly converts the incident solar radiation into electricity, with no noise, pollution or moving parts, making them robust, reliable and long lasting. Because of the above natures we go for Solar PV. The problem behind solar PV is its efficiency. Efficiency of the panel is highly reduced because of the following (i) physical damage, (ii) improper maintenance and cleaning and (iii) aging. Aging is caused by the expose of solar PV panels to weather and wind for years. Because of this, output power of the individual panel varies due to dame and overheating of the panel. This leads to loss in their maximum efficiency. The rated power output of solar panels typically degrades at about 0.5% per year. In this paper the analysis and reconfiguration solutions for the aged or old solar PV panels for getting maximum power is proposed. This will be very much helpful for all solar power plants in the future. Keyword: Solar PV, Aged Panel, Reconfiguration, Maximum Power Generation.
