Desert photovoltaic reflective cloth capable of improving light incoming quantity

The invention discloses desert photovoltaic reflective cloth capable of improving light incoming quantity, which comprises photovoltaic reflective cloth, the top of the photovoltaic reflective cloth is in lap joint with a double-sided photovoltaic module, the outer surface of the photovoltaic reflective cloth is clamped with a photovoltaic fixing frame, and the double-sided photovoltaic module is clamped in the photovoltaic fixing frame; along with the rise of the temperature, the extension adjusting layer extends downwards to unfold the metal-plated reflective film layer and increase the focal length of the concave mirror integrally formed by the metal-plated reflective film layer, so that emitted light rays are divergently irradiated on the back surface of the double-sided photovoltaic module, and the phenomenon that the back surface of the double-sided photovoltaic module is sharply heated due to excessive light condensation at a certain position at the bottom of the module is avoided; and on the contrary,
