Abstract

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.
