Design, Simulation and Economic Analysis of A Rooftop Solar PV System in Vietnam

Abstract

Installing a grid-connected rooftop solar system for a household is an important issue; therefore, there are many factors that need to be considered before the installation is decided. The main factors to be noted are the total cost of the installation, the amount of electricity generated as well as the government's support policies for the development of solar energy. This article presents the design, simulation and economic analysis of an 8.36kWp grid-connected rooftop solar power project for a household in Thu Dau Mot City, Vietnam. The study calculates the generated electricity, the efficiency of the Photovoltaic (PV) power system, the ability to reduce the amount of CO2 emitted into the environment and the economic indicators of the project. This research is useful for stakeholders investing in residential rooftop solar PV systems and Vietnam's energy policymakers as well.

Calculating the energy capacity and capacity factor of floating photovoltaic (FPV) power plant in the cirata reservoir using different types of solar panels

“…Then, calculate the energy capacity and capacity factor values for the FPV Power Plant Cirata Reservoir by entering specification data for the monocrystalline, polycrystalline and thin film solar cell module types on "Energy" worksheet. For the required number of unit of solar panels (n) is given in the equation 1 below [21]:…”

Analisis Desain PLTS Atap Tipe Gable Roof menggunakan Metode Weight Score

“…PLN UPT Cirebon yang berkapasitas 258,88 kWp akan berpotensi menyebabkan penurunan emisi dari pengurangan penggunaan energi pembangkit eksisting yang mayoritas didominasi oleh PLTU. Penurunan emisi dapat dihitung dengan cara menghitung nilai produksi energi tahunan yang dikalikan dengan faktor emisi jaringan ketenagalistrikan wilayah Jawa-Madura Bali (Nguyen & Van, 2018). Sehingga menurut pedoman teknis perhitungan emisi yang dikeluarkan oleh Bappenas (Bappenas, 2014), total nilai penurunan emisi pada skenario 1, skenario 2 dan skenario 3 dapat dilihat pada Tabel 12.…”

Design and Techno-economic Simulation of a Standalone PV Solar Power Plant for a Typical Housing Estate in Owerri, Nigeria

“…The performance and economic viability of a grid-connected rooftop solar PV system in Vietnam was studied and the PVSyst simulation results show that an 8.36 kWp system will produce 11,106 kWh of electricity in a year, saving the planet about 8.7 tons of CO 2 per year [26]. The cost of installing the system, annual average system efficiency, and energy payback period were also estimated as 5,691.7 USD, 81.17%, and 12 years, respectively.…”
