Solar garden lights use poly-crystalline panels, which recognise when sunlight strikes them and then store energy in the battery. Lithium ion (Li-ion), lead acid, or nickel metal hydride (NiMH) batteries are all utilised in solar garden lighting. Due to the various materials used in their construction, these batteries offer varying performance. Although NiMH batteries are environmentally beneficial, it is not suggested to use them in solar illumination due to their high self-discharge rate and decreased performance in high temperatures. Although lead acid batteries require frequent maintenance, they are quite inexpensive. In gloomy situations, it may take longer for the panel to produce the necessary 6 to 12 V to charge the battery.
To charge the battery, the panel must produce at least 6 to 12 volts, therefore under cloudy situations, charging the battery may take longer.
Li-on batteries are easier to charge on overcast days since they are more compact, dependable, and low maintenance than NiMH batteries. Although more expensive, lithium ion batteries last longer than lead acid batteries but less than NiMH batteries due to their weight and fast self-discharge rate, which causes NiMH batteries to lose a significant amount of their charge each month.
