Streetlights have somewhat become a very popular feature of the urban nights. They are found on public roads, in estates, parks and on the fence walls of residential buildings. In rural areas as well, streetlights are becoming ubiquitous as Nigerian politicians have made delivering streetlights a part of their campaign promises.
Streetlights are installed mainly for security reasons. They also help pedestrians, drivers and vulnerable users of the road at night thus reducing the risk of accidents. Also, they have aesthetic value as they help beautify the night.

How Solar Streetlights Work
Incorporated solar panels trap sunlight and convert it into electricity. This process occurs during the day. As solar streetlights do not work at night, this energy is stored in the battery for use at night time.
At night, photoreceptors shutdown the solar cells and the battery in turn will start supplying power to the LED lamp through wiring in the lamp.
Solar streetlamps are 'intelligent' in the sense that the photocells activate the lamp automatically when needed, at times when there is little to no ambient light, such as at dusk or dawn or at the onset of dark weather conditions.
Unlike the conventional streetlights that are uses low-pressure sodium lamps, solar lamps are mostly LED lights.
Also, they come with controllers that help prevent overcharge and overload and any damage to the lamp and battery.
Types of Solar Streetlamps
Solar streetlights may have its different parts, battery, lamp and solar panel incorporated into one single piece. Or its different parts may be split either entirely or in semi-incorporated units.
A semi-split streetlight comes in two parts, lamp body and solar panel. A full-split streetlight will have all its different parts separated and installed manually. Local manufacturers can make streetlamps by using local materials to weld together a solar panel, a battery and a lamp.
Solar streetlamps require much less maintenance in comparison to conventional streetlights. Since wiring is not required, the risks of accidents are reduced. Also, they are more durable and have a longer lifespan than conventional streetlamps.
Solar streetlights are an option for public roads, estates, grounds and residential homes and as always SolarKobo helps its clients make the best choice of all solar-based systems. We also have university-trained electrical engineers that offer high-value installation and post-installation maintenance services on order.
