Abstract

The limited availability of natural resources and the impact on the environment that regularly using fossil-based electricity become the basis for the government to develop renewable energy. One of the potential uses of renewable energy in Indonesia is a rooftop solar power plant which in its design does not require a large area of land and space for the placement of solar modules. This research designing rooftop solar power plants with an on-grid system on the Udayana University Rusunawa building with the capacity scenario of 20 kWp, 15 kWp, and 10 kWp using HelioScope. Based on the results of rooftop solar power plants production can be seen the potential cost savings of electricity bills each year. Based on the results of the design for rooftop solar power plants scenario, the number of solar modules obtained is 40 pieces, 30 pieces and 20 pieces with potential savings in electricity bill costs of Rp. 33.391.515, Rp. 28.933.478 and Rp. 23.269.285 per year.

Abstract

Using sustainable energy as a source of electrical energy is a safe way to increase ecosystem energy. One of them is the utilization of photovoltaic directed energy by upgrading the PLTS on top of the structure as a mechanism for introducing photovoltaic modules. The study finalized the plan to install PLTS on the roof of the I Gusti Ngurah Rai Airport parking lot as a source of electrical energy to reduce PLN electricity bills. The I Gusti Ngurah Rai Airport Parking Roof Solar Power Plant uses a battery-free on gridsystem with 600 units of 555Wp monocrystalline solar-based modules and four 100kW inverter units. The solar power plant to be built on the car park of Terminal I Gusti Ngurah Rai will have a capacity of 333kWp and will produce 604.929kWh of energy annually. The required speculation cost is Rp 3.004.620.000 and payback period for 6 years.

Abstract

The government will continue to increase the use of new and renewable energy as a solution to meet electricity needs, one of which is the use of rooftop solar power plants. In this research, the location that will be planned to install rooftop PV solar system is the Udayana University Rusunawa Building. The produced energy will be able to meet the electrical energy need and as well as supporting the government programs in the utilization of new and renewable energy. The capacity of the rooftop PV solar system to be installed is determined based on the load profile of the Udayana University Rusunawa Building. Three different scenarios namely 20 kW, 15 kW and 10 kW PV solar systems have been simulated using a PV solar simulator. Results of the simulation scenarios then are compared to look at the differences among the produced energy.

Abstract

The installed PLTS capacity in Bali is currently still 3.44% of the target given by the General National Energy Plan (RUEN) of 108 MWp in 2025. The island of Bali has limited land availability so rooftop PLTS is a solution. The design of the rooftop PLTS was carried out on the roof of the Wisti Sabha Building at I Gusti Ngurah Rai International Airport. The research uses PVSyst simulation software while the investment feasibility method uses the Benefit-Cost Ratio (BCR), Net Present Value and discounted payback period (DPP) methods. Based on the simulation results, the rooftop PLTS capacity is 56.6 kWp with energy production of 98,009 kWh/year. The B-CR value obtained is 2.23, the net present value is IDR 707,436,838.55 and the DPP is 7 years, with a rooftop solar system life of 25 years.

Abstract

Indonesia has a huge potential for solar energy, but its utilization until 2024 only reach 573.8 MWp. The low utilization of solar energy is caused by the limited vacant land for solar power plant installations, especially in urban areas. Rooftop solar power plants are expected to increase the use of solar energy in urban areas. Choosing the right solar panels on rooftop solar is necessary to get the best performing solar panels even though they are placed on limited land. The development of cell arrangement and shape technology in solar panels has resulted in full cell, half-cut cell, and shingled cell solar panels. The weather parameter observed in this study is sunlight radiation. Direct observation was carried out for 4 days at 08.00-16.00 WIB in the Kediri Meteorological Station (BMKG Kediri), with data collection every 5 minutes. The results of the study show that sunlight radiation has a significant influence on the output power of solar panels. The determination coefficient (R2) value of sunlight radiation against solar panels is 0.60 in monocrystalline full cells, 0.65 in monocrystalline half-cut cells, and 0.66 in monocrystalline shingled cells.
