4. 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 .

12. 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.
