Except for a few cities, most of the cities will let their streetlights run through the night and waste power in the process. What is the best way to save power? You do not leave lights on all night, which is exactly why we have seen quite a number of teams come up with streetlights containing solar panels. However, this Spanish team is planning to take things up a notch or two by coming up with a standalone streetlight that relies on solar and wind power both.Streetlight that Runs on Wind and Solar Energy

The project is a joint venture of Universitat Politècnica de Catalunya and Elogreen (Spanish startup). The current prototype has a height of 10 meters and comes equipped with an array of LED lighting. The prototype also sports photovoltaic panels, a battery pack, a wind turbine and an electronic control system that is responsible for the flow of energy that takes place between these components.Streetlight that Runs on Wind and Solar Energy2

The turbine has composite-blades and it springs into action when wind speed reaches 1.7 meters per second. It executes 10-200 revolutions per minute and cranks up a power output of 400 watts. There are plans of incorporating a 2nd gen turbine that will work with an rpm of 10-60 while creating 100 watts in the process.Streetlight that Runs on Wind and Solar Energy4

As per plans, the commercialized version will feature two solar panels  with a power rating of 100 watts along with an array of Phillips LEDs that can generate 3500-4000 lumens based upon the model of the streetlight. The product will also be containing a battery pack which will reportedly be able to store enough power to keep the light running for almost 3.5 nights per single charge. Streetlight that Runs on Wind and Solar Energy5 Streetlight that Runs on Wind and Solar Energy6

99 of these lights will be able to relay status updates over UHF to the central station while working off the grid once every 30 minutes. This will enable the station staff to take care of any technical problem when and if it arises. Elogreen has entered into partnership with a number of Spanish municipalities and has plans of coming up with 700 lights this year only. Let’s wait and see how this light performs once it rolls out.
