Abstract
Malaysia, being a tropical country with abundant solar energy potential, has experienced a significant growth in the adoption of solar power systems. However, the variability of solar irradiation due to factors like cloud cover, fluctuating sun intensity, and rainy season conditions poses challenges for optimal power generation from solar panels. To overcome these challenges, it is crucial to implement a DC-DC boost converter to stabilize the output power. The project aims to boost the low solar panel voltage for charging the battery on cloudy days and analyse the current and voltage readings for this purpose. The project involves exploring MPPT modules, integrating an MPPT module with a DC-DC boost converter, and conducting tests with and without the boost converter using a solar panel to charge a battery. The results of the tests are compared and analysed, highlighting the effectiveness of the boost converter. The findings demonstrate that the boost converter is essential in charging the battery even during cloudy days, enabling efficient charging at a low voltage of around 6.5V. This showcases the boost converter's effectiveness in increasing the voltage of the low solar panel voltage to effectively charge the battery under unpredictable weather conditions.
