## Abstract

Embodiments herein provide a solar appliance. The solar appliance comprises an outer shell and an inner shell having at least one platform for placing one or more containers. Each of the inner shell and the outer shell are made of a preselected material. The inner shell is configured for receiving the sunlight for heating content inside the one or more containers. The solar appliance further comprises a gap provision provided between the outer shell and the inner shell for allowing a circulation of a medium. The medium insulates the inner shell and conserves the heat inside the inner shell.

## Claims

### Claim 1

A solar appliance, comprising:
an outer shell;
an inner shell having at least one platform for placing one or more containers, wherein each of the inner shell and the outer shell are made of a preselected material, and wherein the inner shell is configured to receive the sunlight for heating content inside the one or more containers; and
a gap provision provided between the outer shell and the inner shell for allowing a circulation of a medium, wherein the medium insulates the inner shell and conserves the heat inside the inner shell.

### Claim 2 (depends on 1)

The solar appliance as claimed in claim 1, wherein the solar appliance comprises a length in a range of 550 mm to 580 mm, a width in a range of 520 mm to 550 mm and a height in a range of 280 mm to 320 mm.

### Claim 3 (depends on 1)

The solar appliance as claimed in claim 1, wherein the preselected material of the outer shell comprises a transparent material.

### Claim 4 (depends on 1)

The solar appliance as claimed in claim 1, wherein the preselected material of the inner shell comprises one of a transparent material, a semi-transparent material, or a non-transparent material.

### Claim 5 (depends on 1)

The solar appliance as claimed in claim 1, wherein the at least one platform of the inner shell is provided with a radiation absorbing coating.

### Claim 6 (depends on 1)

The solar appliance as claimed in claim 1, wherein the medium comprises an air.

### Claim 7 (depends on 1)

The solar appliance as claimed in claim 1, wherein the medium comprises a non-inflammable non-reactive gas maintained at one of an atmospheric pressure, a pressure higher than the atmospheric pressure or a pressure lower than the atmospheric pressure.

### Claim 8 (depends on 1)

The solar appliance as claimed in claim 1, comprising:
a door covering an opening of the solar appliance.

### Claim 9 (depends on 1)

The solar appliance as claimed in claim 1, comprising:
a mounting flange for mounting the solar appliance over a predefined place; and
a mounting bolt for supporting the mounting of the solar appliance.

### Claim 10 (depends on 1)

The solar appliance as claimed in claim 1, wherein the predefined place comprises one of a window, a wall, or a vertical, or a stand-alone place.

### Claim 11 (depends on 1)

The solar appliance as claimed in claim 1, comprises:
a temperature control knob for enabling an exit of the medium from the inner shell, wherein the exit of the medium controls the temperature inside the inner shell.
