An emergency power resource can be provided through photovoltaic (PV) panels attached to a motorcycle. This work proposes a solar energy based system that can generate electricity for motorcycles when the batteries are out of power. An appropriate-sized solar panel is used to first generate electricity that is stored in a lithium battery. When there is shortage of power in motorcycles’ battery, the lithium battery will be used to power up the motorcycle battery so as to supply power. This is very useful in case of emergencies when the batteries are completely out of energy. This research uses 2 pieces of 230 x 155 mm polycrystalline silicon solar panel with 3.5WP to generate power into 4 pieces of 3.7V lithium batteries. Owing to the characteristics of fast charging of lithium batteries , the high voltage, and the low discharge, this method greatly improves the charging time and the unpredictable problem of sunlight, when compared to directly charging power into the storage battery using the solar panel. Experiments show that the proposed system requires only 3 hours 20 minutes , compared to the 4 hours required when direct solar charging is used.
