The payment model for generated kilowatt-hours (kWh) has been phased out since 2013, followed by the discontinuation of Net Metering in 2024. Under the current Net Billing framework, a photovoltaic system is no longer installed to sell electricity to the utility grid; rather, it is designed for self-consumption, aimed at eliminating the need to purchase electricity from the power company. However, since PV systems generate electricity only during daylight hours while energy demands persist around the clock, implementing an energy storage solution is essential to ensure continuous and uninterrupted supply. This is achieved through the integration of batteries, which significantly increases real-time self-consumption and reduces energy exchange with the grid. Additionally, the battery system can function as a Backup Power Supply (UPS) to sustain critical household loads during power outages.
