Solar Powered Street Lights
These two pictures by Capsat on Flickr are making rounds on the various Pakistani mailing lists. We received this tip from Jamal Shamsi first. The second picture showing the truck installing the solar powered street light seems to be inside some CDGK compound.
CDGK has gone a great job in replacing regular white street lights with sodium (yellow) lights in many localities. It gives a good lightening effect. However, a very high number of non-system connected street lights remain on 24/7 (see a previous entry on KMB on this topic) and this causes great power loss in a time when power is most needed. Street light power consumption is estimated at 24 megawatts in Karachi.
Theft security (apart from the price) of the solar panels atop these experimental arrangements might become an obstacle in mass deployment. Also, how long thru the night can these batteries last?
