Solar power was playing an illuminating role in Johannesburg inner city regeneration efforts, as solar streetlights have been installed on Kenmare street, in Yeoville as a part of the Hillbrow, Berea, Yeoville upgrade being carried out by the Johannesburg Development Agency (JDA).
Broadwing Technologies installed the three solar streetlights.
"Evaluation was done together with the JDA, to monitor performance, and it was found that the solar street lights were not only satisfactory, but exceeded their [JDA's] expectations," according to Broadwing Technologies director Dan Hurwitz.
The cost of the installation of solar streetlights was said to compare favourably with the cost of installation of conventional streetlights. "The capital cost is more or less equal to the traditional grid-connected streetlight, but there are a number of additional benefits," Hurwitz added.
Lifecycle maintenance costs of the installation are favourable as the Light Emitting Diode (LED) bulbs used in the streetlights, use a lower voltage to produce a brighter light and can be used without replacement for about 20 years. "The thin-film solar panel used has a very high temperature tolerance, and is immune to damage from hail," stated Hurwitz.
