In Solar street and garden lighting systems, many people mistake solar panels for batteries. In fact, their functions are completely

different. For example: The solar panel is like an eye, receiving sunlight; the battery is like a stomach, storing energy.

1. Core functions: One for generating electricity, the other for storing electricity

Solar panel (solar cell panel): It is a power generation component, composed of single/multi-crystalline silicon semiconductors,

and converts light energy into electrical energy through sunlight exposure.

Features: It generates electricity as long as there is sunlight, but it cannot store electricity itself.

Battery (storage battery, lithium battery / gel / lead-acid): It is an energy storage component, capable of converting electrical

energy and chemical energy.

The electricity generated by the solar panel during the day is stored in the battery, and it is used to power the lamps at night.

Both are indispensable: Without the solar panel, the battery will run out of power eventually; without the battery, the

electricity generated cannot be retained.

2. Appearance and location, quick identification

Solar panel: Installed above the lamps, with a larger area, black / dark blue in color, having grid-like textures on the surface, facing

upwards to receive sunlight.

Simple judgment: If it is blocked by sunlight, it will stop generating electricity.

Battery: Mostly hidden in the lamp head, control box, or external boxes, usually not visible externally; for the external-mounted

type, it is a sealed box with marked voltage and capacity.

3. Common faults and misunderstandings & maintenance

1. The lamp not turning on does not necessarily mean the battery is damaged. If the solar panel is covered with dust or blocked

by leaves, it cannot receive electricity, and the battery will be depleted, even if a new battery is replaced. The priority is to clean

the solar panel and remove the obstruction.

2. Solar panel glass cracking cannot be used as is. It will be affected by moisture and oxidation, resulting in a significant decrease

in power generation capacity. Even if the battery is intact, the lamp's battery life will be poor, and the solar panel needs to be

replaced.

Simple mnemonic: Panel generates electricity, battery stores electricity.

The key points of daily maintenance are to wipe the solar panel, check if the battery connections are loose, and extend

the lifespan of the lamps.
