Runs on solar without problems. For the construction you do not need instructions. That goes with a little mind quite quickly. Use pots, attach hose to the upper pot, fill the pump in the bottom pot, lower pan of water, connect pump with solar panel (on the socket is "pump"). Finish - fountain running - as I think even with relatively low-noise motor. The batteries are in principle unnecessary, unless you want to leave the fountain running at night. The pity is that the well must always turn on the solar panel if it is not running overnight. I'll probably switch the bridge. The fountain is in my garden, it is illuminated at night with external spotlights - so the lamp was not necessary. He looks good and the birds are happy. Buy recommendation !!!
