Solar Power Christmas Lights - Have a Green Christmas
Traditional Christmas lights use incandescent light bulbs and waste most of the
electricity in the form of heat. This energy waste is evident by the deep snow
wells around lights where the bulbs have melted the snow. These strings of lights
put a strain on the electrical grid and cause energy demand to reach seasonal
highs. As an alternative to traditional electric Christmas bulbs, solar power Christmas lights
use clean, environmentally friendly power from the sun to create decorative & fun displays.
Christmas can be made to be a green holiday. Saving electricity during the long
nights helps to reduce the amount of carbon emissions and toxic waste being generated.
An outdoor Christmas display using traditional lights can use more than 1 kiloWatt of power per
night. Across a city, that's a lot of extra power demand and a lot of extra pollution.
HOW THEY WORK
Solar power Christmas lights use Light Emitting Diodes (LED) as bulbs which may
not as bright as traditional Christmas bulbs, but provide the same festive and decorative
effect. They work the same way as solar garden lights and have a solar cell,
a battery, a light sensor and a string of LED bulbs. The light that is produced is bright
and clear but uses the free energy of the sun.
The amount of energy needed to power these LEDs require just a few hours of sunlight
to recharge a battery. During the day, the light sensor automatically turns off the LEDs
and allows the solar panel to re-charge the batteries.
As the winter sun sets, the LEDs turn on and the battery supplies the stored energy to the bulbs.
Depending on the amount of sunlight that was converted and stored in the battery, the lights can
stay on for up to 8 hours, well into the night. If the sky is overcast during the day, the battery
will only be partially recharged and the lights won't stay on as long.
PRODUCT CHOICES
Unlike the solar garden lights, Christmas
lights integrated with a solar cell are relatively new products. They come in a variety of shapes,
colors and lengths. The long-lasting bulbs are permanently attached to the string and if one were
to blow, the rest would continue to shine. A few products have replaceable LED bulbs.
Look for a unit where the solar panel can be place at a distance from the sting in an open area
clear of obstructions and shadows. The solar cells need as much
exposure as possible to the limited amount of winter sunlight available. Also, place the unit
where it is easily accessible in order to clear away snow that may have accumulated on the panel.
In the next few years, solar power Christmas lights will become as popular as solar power
garden lights. They are efficient, long-lasting and environmentally-friendly alternatives to
wasteful traditional lights. Even though the Christmas season is synonymous with snow and
ice, these lights will help make the holidays greener.
