Stay cool in the shade with this solar patio umbrella. Be sure to use the patio market umbrella with an umbrella base and patio table (not included) for proper support. The 1.5" diameter pole allows for use with standard bases (not included). The push-button tilt feature lets you control the angle of the canopy for just the right amount of shade no matter the time of day. The crank makes opening and closing the canopy smooth. Also, the vented top gives the patio umbrella more stability in the wind. The solar panel is located on top and operates all 24 LED lights located on the umbrella ribs. When fully charged via solar power, the lights will last 6-8 hours.
