Solar outdoor lights could turn out to be inexpensive and feasible alternatives for the traditional outdoor lights. However, it would be good learning a bit about the inside of the solar light fixtures before one installs them in his or her garden or backyard. Single Mounting Flipping open the cover of the solar light, one can see that the entire structure comprises of a single mounting. Other things that would immediately attract the attention of the user are the battery, controller board, and the LED. Once again, the battery is a single unit. When the sensor cover is put on the LED is turned on. Entire lighting system is regulated using the control board attached to the unit. Other Parts of the Solar Light System Some other components of the solar light system are ††Four cell solar array that measures two squire inches or five square centimeters in size. †The photo-resistor that helps the device to identify darkness. How the System Works †Battery of the outdoor solar lights or other solar light fixtures gets charged day time. †It does not mean that the charging involves bright light all along. Though the charging could be nicer with bright light, even in the faded light during rainy or winter seasons, the battery can get charged well. Lighting the Yard at Night One of the major conveniences in using the outdoor solar lights or garden lights is that they can generate illumination automatically by turning on during the night or when darkness creeps in. Usually the solar yard lights will use the standard solar cells. The application is quite straightforward. While the battery remains charged storing power just in the same way the cell phone batteries work, the photo-resistor works to generate automatic lights once the environment gets darker. Solar Cell Components Components of solar cells in the solar outdoor light or indoor solar decorations are as follows ††Glass covers protecting the cells. †Front contact grid. †An anti reflective coating that absorbs sunlight without reflecting it away. †Solar cells sandwich that contains N type free electron and P type silicon those together forms the electric field. †N type negative silicon and P type positive silicon in the device works to generate the power from stored energies. Back contact in the device helps the cells to obtain power from the battery.
