, Description:FIELD OF INVENTION
The present invention relates to a solar embedded weather proof roofing system with thermal insulation and ceiling unit comprising three layers, a solar photo voltaic power generating layer [200] a Mechanical Reinforcement layer [201] and the ceiling layer [202] wherein the Mechanical reinforcement layer [201] is placed in between the power generating layer [200] and the ceiling layer [202].
BACKGROUND OF THE INVENTION
Solar photovoltaics have witnessed exponential growth since 2007. During this period, solar photovoltaics have evolved from small scale energy applications to a mainstream electricity source. Power generated from solar projects has a share of 32% (~23 GW) of the total renewable energy capacity in India and the installed capacity has grown from a mere 10 MW in 2010 to 23,022 MW in 2018. The capacity addition of rooftop solar has yet not seen significant growth, contributing only around 6% to the total solar energy mix. However, with the availability of better technologies, rooftop solar is expected to make huge additions in coming years.
Conventional techniques to install solar roof top consist of solar panels supported by metal mounting structures which affect the aesthetic appearance of the buildings. Installation of solar panels supported by metal mounting structures cannot be installed stably on all buildings. Building integrated photovoltaics widely installed is an amorphous thin film solar cell integrated to a flexible polymer module which is attached to the roofing membrane using an adhesive sheet between the solar module back sheet and the roofing membrane.
The present invention is a viable alternative to the conventional techniques and is more economical and efficient.
Installations of solar photovoltaic technologies on building rooftops with solar photo voltaic modules and mounting structures are common in all part of the world. The common systems are composed of solar panels that are mounted on the roof using different types of mounting structures. System designs are most influenced by photovoltaic performance considerations and aesthetics are often secondary. Building Integrated Photovoltaics is the integration of photovoltaics into the building envelope. The photovoltaic modules serve the dual function of building skin—replacing conventional building envelope materials, roof, facades etc. and perform as a power generator.
The main disadvantage of the existing solar building integrated roofing products is the low efficiency due to the high operation temperature of solar cells compared to the rated operating temperature of the solar cells since no provisions given to prevent overheating. High operating temperature will reduce the efficiency of the solar cell and chances are high for solar cell degradation. The present invention overcomes this limitation as the hot air will be removed instantaneously through the space between the protruded sections provided because of the density difference of hot and cold air. Gradual removal of hot air will enhance cooling of solar photo voltaic power generating layer and the operating temperature of the Photo voltaic cell will reduce significantly which in turn will increase the overall power generation efficiency.
Existing Building Integrated Photovoltaics technologies cannot prevent heat infiltration in to the buildings – Usually solar cell converts less than 20% of the incidence solar energy in to electricity. The rest of the incident energy is absorbed by the Building Integrated Photovoltaics material and transfers to the building as heat energy, this leads to uncomfortable increase in the temperature of the building interior. The present invention by its three layers and an internal cavity filled with thermal insulation materials such as polyurethane, mineral wool, Styrofoam etc to prevent the transfer of heat into the building. The present invention also seeks to sink with the aesthetic appearance of the building unlike the conventional and building integrated photovoltaics which contradicts the aesthetics of the building. The conventional and building integrated photovoltaics have low impact strength and are prone to trespass. The present invention overcomes this limitation.

Another object of the present invention is to have three separate layers which can be detached from each other for easy maintenance.

Another object of the invention is to provide multilevel thermal insulation.
Yet another object of the invention is to increase the electricity generation from the solar system by reducing the operating temperature of the power generating layer.
A further object of the invention is the ease of installation, maintenance and handling.
Another object of the invention is to provide a cost effective alternative to solar roofing solutions.
Further objects and advantages of this invention will be more apparent from the ensuing description.

The Mechanical reinforcement layer [201] is the component which holds the power generating layer [200] and the ceiling layer [202] firmly in position. The mechanical reinforcement layer [201] is made up of metals or alloys or fiber or composite or plastic. The Mechanical reinforcement layer [201] has an internal cavity [213] and is filled with thermal insulation materials such as polyurethane, mineral wool, Styrofoam etc. Three numbers of protruded sections named ribs [203] are placed on the top surface of the Mechanical reinforcement layer [201]. The side surface of each left and right side rib has grooves [204] along the length of the rib and the central rib has a square groove along the top surface of the central rib to lock the Power generation Layer [200] in position. This protruded section are placed in such a way that 2 numbers of air columns is created between Mechanical reinforcement layer [201] and solar photo voltaic power generating layer [200] .
The air between the Mechanical reinforcement layer [201] and solar photo voltaic power generating layer [200] will be heated up during day time as the operating temperature of the solar photo voltaic power generating layer [200] increases due to sun light. This hot air will be removed instantaneously through the space between the protruded sections provided because of the density difference of hot and cold air. Gradual removal of hot air will enhance cooling of solar photo voltaic power generating layer [200] and the operating temperature of the Photo voltaic cell will reduce significantly which in turn will increase the overall power generation efficiency.

The edges of Mechanical reinforcement layer [201] are designed so as to ensure perfect overlapping and interlocking between adjacent roof units. The design of Mechanical reinforcement layer [201] ensures overlapping of each row to the immediate row below it by an overlapping tail [208]. To enhance the leak proofing of this overlapping joints, the upper edges of top surface of Mechanical reinforcement layer [201] is provided with beadings [209] and the lower edges of the bottom surface of the overlapping tail of Mechanical reinforcement layer [201] is provided with grooves [210].
There is a downward bend of depth 5cm from the upper right side of the base plate of mechanical reinforcement layer [201] throughout the width of base plate, named Fixing leg [211] with two screw holes. This leg is screwed to the metal reinforcement structure (truss) of the building. The legs of the mechanical reinforcement layer [201] will increase the overall strength of the roof and improve its ability to withstand wind. Once fixed, it cannot be dismantled from outside, which will increase the safety of the building from trespassing.
Bracket type fixtures [212] are integrated at the bottom surface of the Mechanical reinforcement layer [201], for fixing the ceiling layer [202] in position. It is a lock type mechanism which ensures easy installation of the ceiling layer [202].
The Power generating layer [200] is the solar power harvesting unit of the invention. The Power generating layer [200] contains crystalline or amorphous type photo voltaic cells [214] embedded between two glass layers. The top glass sheet used is Anti-Reflective coated tempered glass and the bottom glass sheet has three locking pins [215] which helps the power generation layer [200] locked into the mechanical reinforcement layer [201].
Ceiling Layer [202] is used at the indoor side of the roof. Metals or cement sheet or treated wood etc. are used to make the Ceiling Layer [202] which is primarily used to cover the truss elements of the building and further helps to reduce the passive thermal conductivity by providing a space between mechanical reinforcement layer [201] and Power generating layer [200].
The two adjacent edges of the Ceiling Layer [202] have a 1 cm overlapping groove [216] to perfectly overlap to each other while installing. The bottom side of the Ceiling Layer [202] is painted with textures or patterns to get aesthetic effect to indoor rooms. The Ceiling Layer [202] is fitted with two mechanical reinforcement layer connecters [217] 22cm apart from each other to fix the Ceiling Layer [202] with the mechanical reinforcement layer [201].
