The massive target of installing renewable energy is the focus of this research. Several industrial sectors continue to install PLTS to support green energy. One of the focuses in this research is to see the maximum impact of installing PLTS at 1 point and sharing capacity for each customer. This research uses a radial distribution network system close to the distribution network in Indonesia, where the load profile takes into account the characteristics of Industrial loads, Commercial loads, and Residential loads. This study uses the line equation theorem method to calculate the voltage increase by considering 2 current measurement points, namely the current at the end and the current at the base. The voltage increase obtained is accumulated to be summed up with the customer afterwards. The results are obtained by considering several scenarios such as voltage limits, voltage limits and line loading, and voltage limits, thermal, harmonics in accordance with regulations. The results obtained are close to those of the simulations performed on the software hosting capacity at DIgSILENT. In the Voltage limit scenario, the distribution of each capacity gets the highest voltage of 1.019 pu. The voltage and thermal limits of 40%, the highest voltage yield is 0.999 pu and the channel load is 19.106% based on the capacity division of each customer. The scenarios with voltage and thermal limits of 100%, the highest voltage results are 1.026 pu and the highest thermal is 93,926%. Meanwhile, the regulatory limits that consider voltage, thermal, harmonics, and reverse. The results obtained for the highest voltage is 1,003pu, the highest line loading is 39.556s%, for the voltage distortion value obtained is 36,338 kV
