Thus, the solar modules may be elevated by the traction of the movable supporting lever set while the water amount in the floats is changed, to achieve the effect of tracking the sun following its east or west orientation.

DETAILED DESCRIPTION OF THE INVENTION;
Floating solar PV plant with overhanging solar panels mounted on the peripheral floaters comprises of: Twin pontoons-2 of HDPE material joined by hollow HDPE bolt-17 and nut-15 in a pattern as shown fig-3.
Fig- 6 shows the arrangement of fixing solar panels-1. GI / SS pipe-3 of standard length are used to connect three rows of HDPE pontoons-2. The connection is done using the help of SS stud-7, big washer-9, saddle clamp-5, small washer-6 and SS nut-10 as shown in the fig- 5. Special twisted fork- 12, 13 and 14 are used for fixing the panels-1 with GI/ SS pipe-3.The solar panels-1 are fixed to special fork by using Aluminum Pop rivets- 11 as shown in fig- 6 and 7.
The pontoons between the solar panels is adopted in the North South direction, as shown in fig-1,serves the dual function of walkway for erection, maintenance and for mounting solar panels-1.
Fig-7 shows the arrangement of fixing solar panels on the southern periphery; overhanging the pontoons 2. The South end panel mounting special fork-14 fitted at its lower end and projecting upwards. Each of the southern end overhanging panel has two of the special forks-14 fitted on the frame using rivets-11. The South end overhanging panels are thus fixed to the array by means of these special forks-14 and rivets-11. The lower end of the Southern end overhanging panel is held in position by bracing-4 again through specialforks-14.
Fig-8 shows the arrangement of fixing solar panels-1 on the Northern end overhanging from the pontoons. The upper North end of these overhanging panels at the requisite angle by special forks - 13. The bracing - 4 is attached to the pontoons-2, as shown in fig-8.

Fig-2 shows elevation view in the East west direction. It shows how the panels are disposed in the east west direction.
Fig-9 shows the arrangement of fixing string inverter-19 to floating pontoons. All the DC cables from the solar panels strings are connected to String inverter-lg. AC cable from the string inverter is connected to LT Panel fixed on the lake bank.

ADVANTAGES OF THE INVENTION:
a) Requires about 25 to 30% lesser number of pontoons as compared to
existing art.
b) Blocks lesser sunlight.
c) Structures being mostly cylindrical pipes has lesser wind obstruction
allowing air to easily pass through; reducing mooring cost.
d) Wind' smoothly passes below all the solar panels both mounted on the outer periphery as well as the inner rows. This smooth passage of air below the solar panels has significant cooling effect and a consequential increase in electrical energy generation.
e) The blocks of 50 kW joined with gaps, for fishing, (Ref Fig: 10) permits co¬existence of fisheries (Pisciculture) with floating solar plant giving additional utility of the lake area.
f) By mounting the solar panels on the outer periphery there is no need of walkway and guard chains/rails on the outer periphery thereby minimizing the number of pontoons and also avoids loss of generation due to shadow of guard rails on the solar panels.
