1. An Electrothermal insulation composite (ETC) sandwich structural FRP panel (100), wherein the Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) comprises:
a resin infused Glass Fibre Reinforced Plastic (GFRP) (102);
a Polyurethane Foam (PUF) (104);
a resin infused Glass Fibre Reinforced Plastic (GFRP) (106) an outer layer;
an aluminum layer (302);
a solar panel (108); and
a UV and abrasion resistance transparent hard coating (110).

2.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the Polyurethane Foam (PUF) (104) acted as a thermal core with a thickness ranges from 10 mm to 200 mm.

3.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the resin infused Glass Fibre Reinforced Plastic (GFRP) (102) & (106) a thickness ranges from 1-3 mm bonded externally on both sides of the Polyurethane Foam (PUF) (104).

4.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the resin infused Glass Fibre Reinforced Plastic (GFRP) (102) is optionally coated with a gel coat, a thin layer.

5.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the Electrothermal insulation composite (ETC) sandwich structural FRP panel (100), the total thickness ranges from 12 mm to 205 mm.

6.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the electrothermal insulation composite (ETC) sandwich structural FRP panel (100) offers thermal insulation protection from room temperature (25°C) to elevated temperature of 60°C with reduction of temperature gradient at least to 10°C depending on the environment and applied insulation thickness.
7.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the solar panel (108) is exposed to direct sun radiation to receive the sunlight and converted it into electricity.
8.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the aluminum layer (302) is an optional layer.
9.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the aluminum layer (302) is a thermal coolant that absorbs the heat generated by the solar panel (108) and increases the efficiency.
10.The Electrothermal insulation composite (ETC) sandwich structural FRP panel (100) as claimed in claim 1, wherein the UV and abrasion resistance transparent hard coating (110), a top layer, protects the solar panel (108) from the damaging effects of UV radiation, extending their lifespan and maintaining the efficiency of the solar panel (108).
