FIELD OF INVENTION:

The invention generally relates to roof top solar Photovoltaic (PV) plant. More particularly the invention describes about seasonal tilt arrangement for solar photovoltaic modules and also about using the heat absorbed by the module mounting structures for productive purpose.
BACKGROUND OF INVENTION:
The prior art of roof top solar power plants consists of module mounting structures which hold the solar Photovoltaic (PV) modules at fixed angle.
Drawbacks of this design are:
1. Water for module washing is provided by a separate arrangement of pipes and not through the module mounting structures.
2. The solar radiation falling on the module mounting structures is not tapped for productive purposes.
OBJECTS OF THE INVENTION:
An object of the invention is to provide an arrangement for seasonal tilt for a roof top solar Photovoltaic (PV) modules for more annual power generation as compared to fixed arrangement.
Another object of the invention is to provide suitable module mounting structure to absorb solar radiation for other utilities.
Yet another object of the invention is to fill the module mounting structures with water whose weight will assist in holding down the solar Photovoltaic (PV) modules.
Yet another object is to pass water through the structures for washing the solar Photovoltaic (PV) modules.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS:
Figure 1 shows an isometric view of Roof Top Solar PV Plant showing seasonal tilt arrangement & Heat soaking mounting structures.
A solar PV module (1) is mounted on a galvanized iron pipe (5) inclined by means of a long angle for seasonal tilting (3). The galvanized iron pipe (5) is painted black to ensure maximum absorption to solar light. A valve (8) is provided at the T-joint (7) for water circulation and module claiming. Each PV module (1) is inclined at a predetermined angle along the long angle (3) by means of a module holding angle (2) to hold the solar PV module (1).
The invention of roof top solar PV plant comprises of network of galvanized iron pipes laid on the roof top. The solar PV modules are connected to galvanized iron pipes through bicycle clamps and angles at the lower end and long angle with four holes at the higher end. Out of four holes in the longer angle one is to fix with pipe through pipe clamp and the other three holes are meant to maintain angular position of module corresponding to three different seasons of the year in order to increase annual power generation in comparison to fixed angle arrangement of prior art. By changing the position of bicycle saddle clamp along the pipe at the higher end of module and selecting a suitable hole in angle different combination of angles for seasonal tilt can be achieved.
Thus with this permutation combination one set of structures could cater to a wide band of latitudes thus doing away with customization required for roof top solar plants at different latitude.

Figure 2 shows a plan View of Roof Top Solar PV Plant with heat soaking mounting structures.
The figure shows plurality of solar PV module (1) interconnected by means of galvanized iron pipe (5).
Water is passed through the galvanized iron pipe structures, the outer surface of which are painted with blackboard paint to maximize absorption of solar radiation falling on the module mounting structures. The water which gets heated up is utilized for various other purposes.
The connection for water for washing of the modules is provided by giving a ‘T’ joint in the pipe structures and an isolating valve.
The weight of water in the galvanized iron pipe structures additionally reduce the weight of concrete blocks/ballast load required to hold the modules on roof against wind uplift and over turning forces.
Thus this invention increases the viability of roof top solar PV plant on account of increased electric power generation due to seasonal tilt arrangement water washing convenience, due to the generation of hot water as a secondary benefit.
Figure 3, 4 and 5 shows seasonal tilt arrangement and heat soaking structures. The module holding angle (2) is altered manually to the desired position of the PV module to achieve maximum absorption.
ADVANTAGES OF THE INVENTION:
1. The invention provides increased electric power generation due to seasonal tilt
arrangement.
2. The invention provides increased electric power generation due to water
washing of modules facilitated by convenient water washing connection provided
in the structure itself.

3. Weight of water contained in the galvanized iron pipes of the structures reduce the weight of the concrete blocks/ballast required to hold the solar PV modules against wind uplift and over turning forces.
4. Hot water as additional yield alongwith electric power increases the viability of roof top solar project with this invention.
5. The galvanized iron pipes and bicycle clamps with constitutes the bulk of structure can be purchased locally thus minimizing the transportation cost.
6. One design of long angle can cater to wide band of latitude thus minimizing customized designs.
