Comments on: Sunlight powers streetlights, Wi-Fi access

A Scottish university is testing solar-powered streetlights that also deliver wireless Internet access.

Climate?

Pardon if I'm displaying abysmal ignorance of solar technology, but would this still function in communities that don't get a lot of sunlight, either from seasonal problems in the far north, or due to prepetual overcast? How much power would these require to operate?

Solar Street Lights

As HEad of CTL let me address some comments.
Firstly our power device is cutting edge technology able to recharge in 'minimal daylight' (yes even up north where its cold...)The power source is strong enough when fully charged to provide Wifi-WiMax-microwave tech and street lighting for over 18 days...without recharging.....
The device does not have a conventional 'solar panel' the UV collection device is moulded to the shape of a street light lamp allowing maximum UV collection throughout the day. Finally, the 'next' stage of development for the project is to have solar powered 'self cleaning' units that are totally maintenance free. Look for more information on this and other related sites.
Kind regards

Director and Head of CTL Scotland

Obviously.

Obviously these would not be installed up north where there is no sunlight in the winter months. Not many people live there anyway. And they do not suit every climate. I'm sure however, that these have regular power from the power grid connected to them for backup, because it indeed would be not logical not to for those situations when there is limited sunlight. And it would be great to have illuminated streets/wifi during a power outage.

Birds ??

If you use a solar panel, it either has to be steeply angled - losing sunlight efficiency - and/or cleaned often due to bird droppings.

These would require an expensive amount of battery time.

Windshield wipers?

Maybe they could add solar-powered windshield wipers.
