Types of Solar Street Lamps
When you pick solar street lamps, you will find two main types. These are integrated and semi-integrated. Each type has a special design. Each works best in different places.
Integrated Lamps
Integrated solar street lamps have all parts in one unit. The solar panel, battery, controller, and LED light are together. You can set up these lamps fast. You do not need to join separate pieces. The design protects the parts from rain and dust. This means you do not need to fix them often. People use integrated lamps where they want easy setups. You see them on small roads, in parks, or on private driveways.
Semi-Integrated Lamps
Semi-integrated solar street lamps have a solar panel that is separate. The battery, controller, and LED light stay together. This lets you put the solar panel where it gets the most sun. The lamp post can be in the shade. You need more time to set up these lamps. You must connect the panel and the lamp. Semi-integrated lamps are good for places with hard sunlight. They also work if you want to upgrade the solar panel later.
Tip: Always look at your site to check sunlight before you choose a lamp type.
Here is a quick chart to help you pick:
| Feature | Integrated Solar Street Lamps | Semi-Integrated Solar Street Lamps |
|---|---|---|
