DC pump performance testing using solar power

The need for water for plant growth requires the provision of water by utilizing alternative energy. The cost of implementing solar energy is still quite high, but the operational costs are lower than the use of fossil energy. This research was conducted in 2 stages, namely the design of the solar panel system-battery-water pump, functional test, and water pump performance test. Measurement of voltage and electric current on a 100 wp solar panel, 70A 12V battery and a 5-watt DC water pump, then proceed with the calculation of the electrical power of the solar panel and battery. Pump performance testing includes water discharge and pump power. The results showed that the magnitude of the voltage, current and power produced by the 70 A 12 V battery was very good in sunny weather with an average value of 13.89 v with a current of 4.25 amperes while the DC pump at a voltage of 13.7v and a current of 4.59 amperage. The DC water pump used is capable of producing 0.167 l/s or the equivalent of 9.6 l/min. For its development, research on the durability of DC water pumps can be carried out.
