PURPOSE:To utilize energy effectively by a method wherein a blind is made up of solar cells, or the solar cells are provided to the outer side of the blind, and electricity generated therefrom is supplied to equipment such as security lamps, ornamental illumination and others that require electric power constantly. CONSTITUTION:At least a part of a blind 2 is made up of solar cells 1, or the solar cells 1 are arranged to slats 3 of the blind. The angle of the light- receiving surface of the solar cell is made adjustable so that solar rays can be received efficiently. Furthermore, a storage battery is provided and electric energy from the solar cells is accumulated therein. Electric power from the solar cells is supplied to equipment such as security lamps, lamps for plant- growing, oxygen supply devices for aquarium fish and others that require electric power constantly. Thereby, solar energy can be utilized efficiently. |
