Abstract
According to the Electricity Generating Development Plan, 2018 an opportunity on the investment of new power plant construction (56,431 megawatts). Regarding renewable energy, there was a ten-year project in 100 megawatts solar power. The design of solar power plant everywhere would have power loss in the electricity generating system which included controllable and uncontrollable systems. Solar panel arrangement could reduce power loss in solar power plant. This research use data of 8 Megawatts solar power plant to analysis the voltage from the manufacturer (30,800 modules all the plant). Arrangement voltage nearby of solar panels making the electricity generating system was better than that of the non-arrangement. The difference in voltage and current of the whole project was 2.22 volt and 0.66 Ampere, resulted in the highly difference in each string and power loss in the electricity generating system (1.28% increase). Based on an economic analysis of the two types of solar power plants based on NPV at 3% discount rate, it was found that both types had a positive NPV. This denoted that it was worthwhile for the investment. For B/C ratio and internal returns rate it was found that the solar power of arrangement had a bit better worthiness (B/C ratio = 1.13 and 1.06; IRR= 3.86% and 3.38%, respectively). For the sensitivity analysis of the investment costs arrangement solar power panel, it was more worthwhile in the investment.
