Q1: We like the zen three tier solar step fountain but were wondering two things: does it store energy in a battery so that it can also run at night and does it have an on/off switch?

A: Our solar fountains do not store energy. They require the direct sunlight to operate the pump. There is no shut off on the fountain you can disconnect the solar panel or put the panel in a shady place.

Q2: How far can the solar panel be from the fountain?

A: The solar panel is located on the very top of the fountain so it will need to be placed in direct sunlight to operate.

Q3: If there's NO direct sunlight (shadow) does it still work? What is the total hight of the fountain? Thank you, Ted

A: If there is no direct sunlight the fountain will not work. The overall height is 9 inches.

Q4: Can Smart Solar fountains be plugged in to house current?

A: At this time there is not an AC adapter.

Q5: How much does it weigh? When the water evaporates (it'll be on my roof) will the pump keep pumping and burn out?

A: This weighs 64 lbs and if the fountain runs dry it will burn out the pump.

Q6: Can the water volume be adjusted? (Specifically to increase water sound.)

A: Yes, there is a flow adjustment on the pump.

Q7: what s the 3 tier fountain actually made of. Does it store enough solar power to work at night? Can I use water plants in all three tiers?

A: This is made from a slate material. These solar fountains do not store energy. We do not suggest plants as they could clog the filter for the pump.

Q8: Is the total height from bottom to top tier is 9 inches?

A: The total height of 9 inches includes the fountain sprayer.

Q9: what is the mesh looking stuff in the bottom

A: It is to help keep the debris from getting into the fountain and clogging the pump.
