Examining Rooftop Solar Power with Integrated Storage Systems under Current Vietnam Pricing Mechanism

With growing concerns about climate change, energy security, and rising electricity costs, a rooftop solar system with storage offers a compelling solution for both residential and commercial consumers. Over the past decade, Vietnam has consistently implemented a series of mechanisms aimed at determining renewable energy pricing and supporting developers due to the high costs of self-investment and the imperative for profitable subsidies. The study examines a rooftop solar system with battery energy storage for a banking office building. By employing the self-consumption method, the system's installed capacity is optimized for economic efficiency. This smart investment solution not only reduces electricity costs for the building but also minimizes reliance on the grid, leading to reduced losses for utilities and a decreased carbon footprint. Furthermore, it encourages sustainable practices and demonstrates social responsibility by reducing the environmental impact of electricity generation.
