<span>Capacitor bank is a collection of power tools in the form of a capacitor that serves as a tool that can reduce or improve reactive power into the power grid. The load on the electricity network in general is an inductive load. If the average power factor (cos ϴ) is less than 0.85, the State Electricity Company will provide the reactive power in KVAR fines usage charges on customers. An effort should be done to reduce the reactive power. An installation of bank capacitor is suitable to be implemented in an industry AC loads. It will reduce the reactive power and improve the power factor. In the case of 380 V, 50 Hz, 500 kW AC loads are improved the power factor from 0.7 to 0.93 using genetic algorithm, thus the AC loads current and reactive power will be decreased. It is suitable that the AC loads current is inversely proportional to the power factor, and the reactive power is proportional to the AC loads current.</span>

Theoretically, the solar tracking system describe as the device to get the optimize amount of sunlight according to sun movement. So, the shading effect issues can be minimized. This paper is presents the finding of photovoltaic (PV) harvesting energy via dual axis tracking system. The operation of two direct current (DC) motors motion was programme using PIC kit SK40C by using the Lab View Programming software. The first motor system delay timer is set at 15° rotation per hour and second motor system delay timers is set to rotate 180° after 12 pm. The field testing was initially set up at Perlis, Malaysia climate. An actual testing was used to collect the daily data. The result shows that, the output voltage with solar tracking system is 12.93% higher than without tracking system in the sunny day condition.
