This decorative solar with battery backup fountain is sure to bring elements of peace, and serenity to any garden, patio, porch or deck. The water gracefully flows from the top of the feature down to the bottom tier where it then recirculates with the help of the submersible pump. Plus, no plumbing is required; once the feature is assembled, simply connect the cord from the pump to the solar panel and place the panel in direct sunlight. No more unsightly extension cords running across the yard and hogging those plugins; just mount and conceal the panel in a sunny place and enjoy! The solar with battery backup option allows this fountain to harness energy even when there is no sunlight! The rechargeable battery pack charges throughout the day (with or without the fountain running) so the gentle water sounds can be enjoyed in the evening as well.
