Sourcetec – Why Solar Street Lights?

WHY USE SOLAR STREETLIGHTS?

A Sourcetec Solar Outdoor Area Lighting system is a reliable and efficient stand-alone system. It consists of a Solar

PV module, a Battery & a Luminary with very high efficiency electronics all mounted onto a pole with necessary

hardware & cables.

The outdoor area lighting system is powered by a Solar Photovoltaic Panel and is completely independent from utility

power. There is no need to excavate for underground power lines, because the system is powered by clean solar

energy.

The energy is generated & utilized at the same place; there are no long distance cables running and hence less

transmission losses. You will enjoy freedom from monthly electricity bills as well as satisfaction that comes with

owning and operating a environmental friendly, renewable light source.

This fully integrated system combines the latest and the most innovative solar technologies available providing years

of convenient trouble free area lighting.

Applications:

� Major Roadways

� Residential Streets

� Pedestrian Walkways

� Parking Lots

� Docks and Piers

� Remote and Rural Locations

� Areas with safety concerns

Sourcetec – Solar Street Light

First: The Light


• The light delivered varies with the power factor

• Ballasts, photocells and lights can all fail. Lights can also lose their lumen efficacy.

• An LED has no ballast. A Sourcetec Solar LED street light uses no photocell. The solar panel generates voltage when there is light and the controller uses this information to determine when to switch the light on

• Traditionally the rated lamp life of light sources is determined by the average time it takes for 50% of lights to fail. LED’s do not typically fail; they decay.

• Lumens per watt for all lamps decay over time.

Light Type Typical lm/Wlm/W (actually

delivered)Lifetime (hrs)

Incandescent 17 14 3k

Halogen 16 16 10k

Metal halide 60 <40 5k-15k

LED 100 55-75 > 60k

High-pressure sodium 80 <50 20-24k

An example of the effects of lumen decay. When the light emitted drops

beyond an acceptable threshold they must be replaced. LEDs do not

typically fail and they decay at a much slower rate than non-SSL lights.


A more evenly distributed light…


Source: US DOE

A direct comparison: Same light pole, same distance between

poles. LED’s versus High Pressure Sodium lights. Notice the

concentration of light around HPS pole and the equal

distribution around the LED poles.


Second: The Power


Why Use Solar Energy?– Annual Cost of Power: Zero

– Solar Production of CO2: Zero

– Effect on Total Cost of Light Production: Profound

– No Trenching required

– No heavy cable, quick easy installation anywhere

– Have lights in days – not months

– Ultra-low maintenance and long product life.

LED light rated for 50,000 hours

– Sealed deep cycle maintenance free battery

(2,200 cycles)

– Solar panel warranty for 25 years.

– We can make it work in Canadian winter sunlight

so we can make it work for you

Actual Installation – Brampton,

Ontario


Third: A Financial Comparison


Source: LED Transformations

This chart describes the financial benefit of using solid state lighting (LEDs). It does not address the solar production.

The cost of the LED is high; the lower cost of solar production and negated cost of trenching installation is significant.

So? Using solar energy garners an additional benefit in further reduced upfront capital cost and ongoing energy cost.

19 Assumed Life 10 years

DESIGN PARAMETER


We have not

extended the

analysis to 20

or 30 years –

merely ten

years.

The annual cost savings are clearly significant.

The system capital cost can be closer if there is no revenue loss due to pavement trenching for a traditional system.
