Three-tier venting across the 10 x 8.1 in canopy allows wind to pass through this solar patio umbrella, improving air circulation under the shade while enhancing stability. Eight heavy-duty metal ribs support the polyester fabric top, and ruffled edges extend the shaded area. Each rib holds four LED lights powered by a solar panel on top, providing about 6-8 hours of illumination controlled by a switch on the pole. A crank handle opens and closes the canopy, while a push-button tilt helps you angle shade as the sun moves.
