Abstract
The increase in conventional electricity or PLN electricity for non-subsidized homes reached 9.7% per year. The cause is influenced by many factors, one of which is the increase in the price of major fuels. One effort to save expenses is to use solar cells as electricity, if this is applied in households, it can save expenses and saved funds can be allocated for other purposes and electricity bills can be reduced by an average of up to 50%. The optimal operating temperature of the Solar Cell itself is 250C, The increase in ambient temperature can reduce the output power. To maximize the performance of the solar cell, an additional system is needed, namely the speed of the water cooling flow in order to produce the maximum voltage or electric current to produce the highest output. The purpose of adding water velocity variations is to reduce the temperature losses in the Solar Cell and optimize the performance of the Solar Cell. From the test results, the greater the flow velocity used, the greater the performance value of the resulting solar cell. The greatest performance of the solar cell lies in the speed variation of 1.18 m/s where the resulting voltage is 19.08 volts, the resulting output power is 7.21 watts and the efficiency of the solar cell is 8.53% and the highest performance low in the solar cell test without variations in water coling flow velocity which has the lowest efficiency of 4.98%. So that with the variation of water cooling flow rate can produce the best solar cell performance value.
