Alternative Energy HQ solar power for homes, wind energy, and bio fuel issues
You’ll be wondering how solar-powered lights work. Solar lights are used when the sun goes down. Thus how is it attainable for them to figure in the dark?
1st of all, understand that lighting devices which depends on solar power usually use a backup battery to operate. Solar cells are used to charge the battery during the day, and also the battery powers the light throughout the night. The solar cells might be connected to the device, or would possibly be located nearby.
This type of lighting is often employed in remote locations, where standard power sources are unavailable, and lights can not be connected to the power grid. They’re conjointly used for out of doors lighting, or as landscape lights around the house or garden.
Parts of Solar Powered Lights
There are four basic parts of a solar powered light. Many solar lighting systems are sold with these components already integrated, but it’s good to understand what they’re:
* The solar cells
* The lamp
* The batteries
* A charge controller
When purchasing solar lights, the bulk of the value concerned can be for the solar cells. These are the most expensive elements of the device or system. Be positive your system is installed among some type of weatherproof housing, therefore that the solar cells and electrical connections will withstand the elements. Guarantee that the electrical elements are protected against moisture in the slightest degree times.
The charge controller is like the “brain” of a solar-powered light. It protects the batteries from overcharging, and maximizes the electrical output of your solar cell array. It conjointly controls the period that the light can operate. While not a charge controller, your setup can not function properly.
Uses of Solar Lights
Most solar powered lights are used to illuminate outside gardens and walkways. The lights are usually cordless, and you’ll therefore move them around easily (unlike with standard lighting systems, where you want to dig ditches and run the wires through).
One disadvantage solar lighting has, as compared to traditional lighting, is that its stored solar power diminishes over time. That means the light might be robust throughout the first few hours of operation, but will then gradually grow dim because the night goes on. This might not be seen as a disadvantage by some, as a result of most outside activities occur throughout the first evening hours. Totally different solar lighting systems conjointly have totally different capacities, and a few last longer than others.
Bear in mind that solar-powered lights depend on the sun to operate, and their performance can be influenced by weather conditions. If the weather is cloudy or rainy, then the battery power can be lesser than it’d be on a sunny day. There also are completely different levels of quality, where solar lights are concerned – the cheaper ones are less economical and don’t last as long.
Hopefully within the close to future, enhancements in solar technology can create solar lighting less costly, and more economical, even during unhealthy weather.
