Abstract During the dry season farmers have struggled watering their crops, because they have to lift water from wells. To irrigate farm land by using his power to lift water to agricultural lands, it is not very effective work by farmers in producing agricultural products. Many of those who can not use water pumps for farm land because away from a source of electrical energy. Solar water pump technology is as an alternative energy to overcome these obstacles. This research was conducted to compare the efficiency of solar water pump using a battery energy source with a pump that only use a charged battery with solar power. A method used in this research is to compare the flow of water is obtained by using a solar electric pump with battery and only using a battery energy alone. When batteries are full and then used to drive the pump, the volume of water obtained is 4590 L. At the during testing by using a water pump battery is work from 9.00 am until 23:00 pm the water discharge obtained is 10710 L. While at the time of testing without using batteries, water pumps can not exist. There are several possibilities among which are the pump power needed for early movers insufficient and unstable voltage and current are get out of solar panels, therefore, solar water pumps without using the battery can not be done.
