Utilization of solar modules (photovoltaic - PV) to generate electrical power is constrained by the low electrical efficiency. Efficiency will also decrease with increasing temperature of PV cells during operation. To hold up a rise temperature of PV, phase change materials can be used. Meanwhile, MPPT can be applied to get the maximum power of PV. Phase change material (Phase Change Material - PCM) used in this research was crude palm oil (CPO). Tests conducted on regular PV, PV that uses PCM, and PV using MPPT, and PV with PCM and MPPT. PCM put in a rectangular tube then mounted on the lower surface of the PV module. MPPT was arrange in series on the PV. Variables measured during the test is the current (I) and voltage (V) from each PV. From the I-V data of the PV, then electrical power and electrical efficiency of each PV can be calculated. From the test results it was found that the use of MPPT on PV can improve the electrical efficiency of PV. average from 10,71% to 16,55%. While PCM applied can increase the average electrical efficiency from 6,42% to 7,72%. When MPPT is used together with PCM, average PV electrical efficiencyc is increased from 9,64% to 16,27%. From the experiment result can be concluded that application of PCM and MPPT can increase electrical efficiency of solar electric module significantly.
