Why Track ?
Maximum energy is absorbed when a PV module is normal to the sun .
Stationary mounted PV panels are only normal to the sun once a day only .
Improved performance from each panel means With the same number of panels, more electrical power can be generated .

Deliverables
The optimum values of tilt angles and orientation of an PV panel in Padaliya, Gujarat were determined using a computer package.
the monthly optimum tilt angle for an PV panel changes throughout the year, with its minimum value as 00 in May, June, July, August and maximum value as 550 in January, November & December.
The gain in amount of solar radiation captured by the PV Modules tracked seasonally is 7.53% compared to fixed tilt.
The gain in amount of solar radiation captured by the PV Modules tracked monthly is 8.49% compared to fixed tilt.
