The base material has a first end portion, a second end portion, and two side portions, wherein the first end portion is configured to be fixed to an anchoring object, so that the base material is disposed by a specific angle with respect to the anchoring object. The first horizontal pole is disposed at the second end portion of the base material. The prop is installed between the base material and the anchoring object, so that the retractable shade system is disposed with respect to the anchoring object in a stable condition. The retractable solar panel is disposed at the base material and configured to be deployed or retracted toward the first end portion of the base material. ## Claims ### Claim 1 A retractable shade system comprising: a base material of a rectangular shape having a first end portion, a second end portion, and two side portions, wherein the first end portion is configured to be fixed to an anchoring object, so that the base material is disposed by a specific angle with respect to the anchoring object; a first horizontal pole disposed at the first end portion of the base material; a prop installed between the base material and the anchoring object, so that the retractable shade system is disposed with respect to the anchoring object in a stable condition; and a retractable solar panel disposed at the base material and configured to be deployed or retracted toward the first end portion of the base material. ### Claim 2 (depends on 1) The retractable shade system of claim 1, further comprising a second horizontal pole disposed between the second end portion of the base material and the anchoring object. ### Claim 3 (depends on 1) The retractable shade system of claim 1, wherein the base material comprises a sunshade. ### Claim 4 (depends on 3) The retractable shade system of claim 3, wherein the retractable solar panel is disposed on a top of the sunshade. ### Claim 5 (depends on 3) The retractable shade system of claim 3, wherein the prop comprises a first prop portion and a second prop portion that are connected by a joint, so as to be folded so that the sunshade and the retractable solar panel are folded on the anchoring object. ### Claim 6 (depends on 1) The retractable shade system of claim 1, wherein the base material comprises a frame formed with a perimeter portion and one or more horizontal and vertical bar portions. ### Claim 7 (depends on 6) The retractable shade system of claim 6, wherein the retractable solar panel is disposed on a bottom side of the frame. ### Claim 8 (depends on 1) The retractable shade system of claim 1, further comprising a winding cylinder disposed at the first end portion of the base material, so that the retractable solar panel engages the winding cylinder and is configured to be retracted into the winding cylinder or deployed out of the winding cylinder. ### Claim 9 (depends on 1) The retractable shade system of claim 1, wherein the base material comprises a frame formed with a perimeter portion and one or more horizontal and vertical bar portions, wherein the retractable solar panel is disposed on a bottom side of the frame, and further comprising a plurality of light lamps attached to the bottom side of the retractable solar panel, wherein the plurality of light lamps are powered by electricity from the retractable solar panel. ### Claim 10 (depends on 1) The retractable shade system of claim 1, wherein the prop comprises a right prop portion and a left prop portion that are disposed to the two side portions of the base material, and each of the right and left prop portions comprises a first end portion and a second end portion, wherein the first end portion is fixed to the first horizontal pole and the second end portion is fixed to the anchoring object perpendicularly. ### Claim 11 (depends on 1) The retractable shade system of claim 1, wherein the base material comprises a frame formed with a perimeter portion and one or more horizontal and vertical bar portions, wherein the retractable solar panel is disposed on a bottom side of the frame, and further comprising a plurality of rings, each of which being attached to a top side of the retractable solar panel and queued to a corresponding vertical bar portion of the frame so as to slide along the corresponding vertical bar portion. ### Claim 12 (depends on 1) The retractable shade system of claim 1, wherein the anchoring object comprises a wall, and wherein the specific angle is between zero (0) and ninety (90) degrees.
