How Do Solar Lights Work

Nicholas Gordon

Description

The most volts a single cell holds is 1.2 volts, it depends on how mu ch Sun it gets as to how long the light last, in the winter with less hours of sunlight and the light doesn't last more them 8 hours.

How Do Solar Lights Work

In my yard I have a lot of different

Solar lights

, Some were so cute they twinkled in the night.

Some marked the pathways through the yard, I even had them on the privacy fence. Most all of

them come with On/Off switch. I lost power one night and brought in a few Solar lights and I

wasn't in the dark anymore. This had me wondering how they were made. So I read up on

them, this is what I found out.

Each light has 4 parts Lamp 1. cover(at

the bottom ) 2.Then LED light, controller

board, NI- CAD battery(rechargeable)

cover. The Solar Cell is what gathers the

energy then sends it to the Battery for

storing. All Solar cells stop producing

power when evening comes. It is stored

in the NI-CAD Battery until the photo

resistor( it is a window to say its dark)

says it's night and now needs the light

bulb to come on. The most volts a single

cell holds is 1.2 volts, it depends on how

much Sun it gets as to how long the light

last, in the winter with less hours of

sunlight and the light doesn't last more

them 8 hours. The Solar cell is wired through a DIODE straight to the battery. The DIODE stops

the current from flowing back out of the solar cell.

One 1.2 volt can store up to 700 milli amp-hours. The Photo resistor turns the LED light on

when it gets dark. It produces half the light a candle would have. These little bulbs if they have

a lot of Sun to store can last up to 15 hours but most go for 10 to 12 hours. Solar Lights are still

expensive because the solar cells are made from Silicon Crystals in a clean room,which make it

costly. I have found different types of solars for a fair price.

Some

Solar Lighting

may have a small Halogen Bulb and LED bulb, also found in flashlights.The

ones with both light bulbs are more expensive and come with a motion detector and come on

for a minute when someone passes the light. These are the best ones to have as they serve as a

nite light. Have them following your pathways and your Gardens at night. Patios look great with

these little lights to glow bright. They come in all sorts of styles.
