Abstract

A support frame is for a photovoltaic power generation system. The support frame includes a frame member including a first portion positioned at one surface of a solar cell panel and a second portion positioned at the other surface of the solar cell panel, wherein the second portion is openably coupled to the first portion.

First claim

What is claimed is:

1. A support frame for a photovoltaic power generation system, wherein a solar cell panel is insertable into and fixed by the support frame, wherein a solar cell panel including a solar cell, a front substrate disposed on a front surface of the solar cell, a rear substrate disposed on a rear surface of the solar cell, a first sealing film positioned between the solar cell and the front substrate, and a second sealing film positioned between the solar cell and the rear substrate, wherein the support frame comprising:
a frame member comprising a first portion to position at a first surface of the solar cell panel and a second portion to position at a second surface of the solar cell panel, and the second portion having an opening to expose the second surface of the solar cell panel such that sunlight can be incident through the opening of the second portion,
wherein a first side of the first portion and a first side of the second portion are hinged-coupled such that the first portion is rotatably coupled with the second portion with respect to the first side of the first portion and the second portion, and
the second portion opens and closes on the first portion,
wherein at least one of the first portion and the second portion comprises a guide portion for guiding the solar cell panel during insertion such that the solar cell panel is inserted by sliding into the support frame from a second side of the first portion opposite to the first side of the first portion or a second side of the second portion opposite to the first side of the second portion,
a support member where the frame member is fixed, the support member to make contact with ground when the support frame is placed on the ground,
wherein the support member supports the frame member to be inclined from the ground,
wherein when the first portion and the second portion are coupled with respect to each other, all sides of the solar cell panel are covered by the first portion and the second portion with the second surface of the solar cell panel exposed through the opening of the second portion.

2. The support frame according to claim 1 , wherein at least one of the first portion and the second portion is formed along an edge of the solar cell panel.

3. The support frame according to claim 1 , further comprising:
a fastener for fastening the second side of the first portion with the second side of the second portion.

4. The support frame according to claim 3 , wherein the fastener comprises a bolt.

5. The support frame according to claim 1 , wherein the guide portion is positioned at a side surface of the at least one of the first portion and the second portion, and
the guide portion has a height the same as or larger than a thickness of the solar cell panel.

6. The support frame according to claim 1 , wherein the frame member comprises a fiber reinforced plastic material.

7. The support frame according to claim 1 , further comprising:
a cushioning member positioned on an inner surface of the frame member where the solar cell panel is positioned.

8. The support frame according to claim 7 , wherein the cushioning member comprises a rubber material.

9. The support frame according to claim 8 , wherein the cushioning member comprises ethylene propylene diene monomer (EPDM).

10. The support frame according to claim 1 , wherein the support member comprises a ground portion and a vertical portion perpendicularly connected to the ground portion.

11. The support frame according to claim 10 , wherein the first side of the first portion is fixed to a first side of the ground portion, and
the second side of the first portion is fixed to an upper end portion of the vertical portion.

12. The support frame according to claim 11 , wherein a length of the vertical portion is variable, and
an inclined angle of the frame member is adjusted by variation of the length of the vertical portion.

13. The support frame according to claim 1 , wherein the first portion is fixed to the support member,
wherein the first portion comprises a plurality of guide portions formed at both lateral sides of the first portion for guiding the solar cell panel when the solar cell panel is inserted, and the first side of the first portion for supporting a lower portion of the solar cell panel, and
wherein the second portion comprises a top side that positions on the second surface of solar cell panel and the second side the covers an upper portion of the solar cell panel.

14. The support frame according to claim 1 , wherein the first portion having an opening to expose the first surface of the solar cell panel such that sunlight can be incident through the opening of the first portion.

15. A photovoltaic power generation system, comprising:
a solar cell panel including a solar cell, a front substrate disposed on a front surface of the solar cell, a rear substrate disposed on a rear surface of the solar cell, a first sealing film positioned between the solar cell and the front substrate, and a second sealing film positioned between the solar cell and the rear substrate; and
a frame member comprising a first portion positioned at a first surface of the solar cell panel and a second portion positioned at a second surface of the solar cell panel and the second portion having an opening to expose the second surface of the solar cell panel such that sunlight can be incident through the opening of the second portion, wherein the second portion is openably coupled to the first portion,
wherein the solar cell panel is inserted into the support frame when the support frame is open and the solar cell panel is supported by and fixed to the support frame through coupling the first portion and the second portion,
wherein a first side of the second portion is rotatably coupled to a first side of the first portion, and a second side opposite of the first side of the first portion is openably coupled to a second side opposite of the first side of the second portion,
wherein the first side of the first portion and the first side of the second portion are hinged-coupled, and
wherein at least one of the first portion and the second portion comprises a guide portion for guiding the solar cell panel during insertion such that the solar cell panel is inserted by sliding into the support frame from the second side of the first portion or the second side of the second portion,
a support member for fixing the frame member,
wherein the support member supports the frame member to be inclined from ground when the frame member is placed on the ground,
wherein the hinged coupled first and second portions are located where the frame member and the support member are coupled.

16. The photovoltaic power generation system according to claim 15 , wherein the first portion having an opening to expose the first surface of the solar cell panel such that sunlight can be incident through the opening of the first portion.
