Philips develops efficient solar powered LED street lighting

January 24, 2012

Philips has developed what is said to be the world’s most efficient and cost effective solar powered LED street lighting solution per km of road.

Philips’ latest Solar Gen2 innovation is developed together with NXP Semiconductors N.V. and presents a total solution for highly sustainable and efficient that is a serious alternative to grid connected systems, cutting back energy costs and CO2 emissions. 

Solar Gen2 offers a highly energy-efficient solution which is superior to any conventional lighting and allows for a lamp post spacing of up to 50 meters, much wider than with other solutions, while at the same time complying with stringent EU road lighting standards (ME3). By charging street lighting during the day, Solar Gen2 can supplement the capacity of the conventional electricity grid. 

Solar Gen2 is especially valuable for towns and cities near the equator, which can take advantage of the many hours of sunlight to supplement the capacity of their conventional electricity grid – and so address their growing concerns about their ability to meet the steep increase in energy demand. In rural areas it can literally light up the lives of an estimated 1.6 billion people who don’t have access to conventional electricity.

“The Solar Gen 2 breakthrough underlines ’ commitment to provide innovative, meaningful solutions that help increase people’s sense of well-being, comfort and safety around the world, while saving energy costs and avoiding CO2 emissions,” reacted Marc de Jong, CEO Professional Lighting Solutions. “By combining the latest LED lighting with solar and battery developments, Solar Gen2 offers a best-in class, reliable and cost-effective off-grid lighting solution that can help cities meet their growing energy demand and significantly improve the lives of people who currently live without electricity,” he further commented. 

René Penning de Vries, CTO at NXP Semiconductors, says: “We’re very proud to have developed this solution in collaboration with Philips Lighting. By making Solar Gen2 as power efficient as possible, we’ve produced something which is genuinely groundbreaking while remaining affordable in those countries that can benefit the most from it. Harnessing the energy of the sun as effectively as possible means reduced electricity demand and a more robust infrastructure.”

The key to the breakthrough lies in the combination of new High Brightness LEDs along with unique patented optics to create the most efficient and robust outdoor lighting system. On top of that, an intelligent charge controller, developed by NXP Semiconductors N.V., ensures the transfer of a maximum amount of power from the solar panels to the batteries. A smart way of charging and discharging maximizes battery life and light levels can be dimmed based on a self learning intelligence and a history log. 

A further benefit of the new solution is that it is future proofed by the inclusion of the Philips LEDGINE, which allows LED modules and drivers over time to be simply replaced and upgraded. In addition, Solar Gen2 includes theft prevention.

Focus markets for Philips solar street lighting solutions are South East Asia, Africa, China, India and North America.

So how much does one cost? How big are the panels? How many watts or lumens do the LED's put out? Does it have batteries?

The answers to your questions depend on many factors- this is not a one-size-fits-all solution. To get an idea of the variables involved when specifying roadway lighting, search for "ME3 roadway lighting standards". I found the OSRAM document regarding the application of LEDs to roadway lighting to be very informative.

What happens if he sun goes dark? There won't be any more street lighting.

There won't be any life left on Earth to care...

This makes more sense than solar-powered crosswalks, which are adjacent to mains and use the equivalent of a few flashlights of power.

Glad to see the have the theft question addressed. Otherwise, they would be showing up in all sorts of unusual places in no time at all.

SolarGen1 was about $3900.00 cdn. 11/2 years ago, one was being considered for an area near where I live in the middle of a park. It had no anti theft which in the end made it a no sale. The lumen output depends on the distribution pattern, but the base array can generate 4500, with multiple array capability to compensate for increased mounting height.
The batteries used are the same as in your computer UPS, building FA system or any emergency lighting battery pack (weatherproof housing added of course). The panel on Solargen1 was a 200 watt. I would imagine the price has come down since then and the panel wattage has been increased. Batteries last app. 5 years before requiring replacements.
It was gonna go in Dundurn Park Vendi.
