Value Addition is a specialist in the design, supply, installation, commissioning and maintenance of standalone solar street lighting systems. We have extensive experience in the implementation of solar outdoor lighting units, be it street, car park or walkway lighting right from concept to commissioning. The solar street lighting systems are meticulously designed to achieve
trouble-free performance that works from dusk-to dawn automatically, round the year. This is achieved by the use of high efficiency solar photovoltaic modules coupled with MPPT charge control and 4 – 5 days battery autonomy.

The two main types of solar street lighting are LED and Induction. Both have superior characteristics when it comes to lifetime, visual efficacy and CRI (Colour Rendering Index). The light beam angle of a LED lamp is normally very narrow and requires a lens to make it wider so as to provide more coverage. Whereas; the Induction lamp, which is essentially a fluorescent lamp without electrodes, gives out a more well spread light output and use a reflector unlike LEDs. With the absence of electrodes, the induction lamp relies on the fundamental principles of gas discharge and electromagnetic induction to produce light. The result of this is a lamp with an unmatched life span of 100,000 hours. The LED also has a lifetime of about 100,000 hours with the lamps showing degradation of output after 50,000 hours. The biggest advantage of LED is it’s high visual efficacy, which means it can replace a conventional HPS lamp with roughly 1/3rd power consumption. The induction lamps, which have slightly lower visual efficacy, can replace an HPS with about ½ the power consumption. The LEDs however are available at various colour temperatures ranging from 3000 to 6500K, which is close to daylight.
