Electricity that produced by renewable energy sources are countinously increased, but some place in Indonesia have not utilize the renewable sources maximally, for instance Kolorai, South Morotai. Based on data from NASA, solar radiation in kolorai is around 5,99 kWh/m2/day, so solar power plant is one of solution to solve electricity needs in remote area like Kolorai. Futhermore, in solar power plant project, determining the load profile and designing the stand alone PV with simulation is important to make a great system. So the optimal methods are needed to build those system, the methods that have higher energy output, less excess energy, dan have a low Net Present Cost. In this paper, Australian/New Zealand standart and manual calculation are used to create an economical design. The result of the HOMER simulation shows that using Australian/New Zealand standart have a suitable result with excess electricity value is 8,56% and Net Present Cost is 1.439.160.000 rupiah.

“…However, off grid system is more sensitive to factors such as shading, design on shorter day in the year, activities during the day and the future demand. These factors can increase the size of the component and directly influence the capital cost of the system as demonstrated [16,17,18].…”

The state of charge (SOC) estimation plays important role in the battery energy storage system (BESS).Nowadays many semiconductor companies are paying more and more attention and investment to support many researchers to implement the state of charge for the batteries storage. the key to optimize the batteries storage is determine SOC value based on accuracy methods. a number of brief methods for SOC determination have been studied and compared with traditional methods the adaptive methods shown precise result because didn't consider the dynamic effect of the batteries. In this paper, we use combination methods to estimate the SOC for lead-acid battery storage under two charge techniques namely Maximum Power Point Tracking -Plus Width Module (MPPT-PWM) when considering the effect of voltage drops on the estimation of SOC. The model uses the coulomb counting as an algorithm to determine the SOC and set it as a target in the backpropagation function in artificial neural network in MATLAB program (R2016a 64-bit (win64)). The simulation results show that the model is very precise to estimate the SOC in realistic operation.

In this study, the design of the components in the system was carried out in order to meet the energy of a stand-alone farm house in Bilecik city only by a photovoltaic (PV) system. Firstly, the loads to be used in the farm house have been determined and it has been calculated that the average energy consumption of the house is 5.58 kWh per day. It was determined that it would be appropriate to use OPzS batteries in the system in order not to have power outage even if there is no solar radiation for 4 days. Under these conditions, it was estimated that 28 batteries 2 OPzS 100 model and 12 V values would be needed in the system. Since the farm house is thought to be used during the whole year, PV panels are estimated to be located at the tilt angle of 40° on the roof, which is the latitude of the city. It has been calculated that 12 PV panels with Per Light 100 Wp PLM-100P/12 model should be used for the system. It has been proposed to use a central inverter system for the design and it is calculated that the inverter should be at least 6 kW power.
