Photoresistor In Solar Panels

Model without visible photoresistor has only two wires coming from solar panel.

Photoresistor in solar panels.

One clearly has a photoresistor while others do not have a photoresistor. Confusion reigns over photocells and solar cells but there is an easy way to tell them apart. Some solar lights have a battery with a capacity of 2000 mah milliamp hours which is a good amount of power storage capacity. A solar cell produces power for an electrical circuit while a photocell is a light activated control switch.

The model with photoresistor has 2 wires coming from solar cell and two wires coming from photoresistor. A photoresistor is the component of the solar light that allows it to detect whether it is light or dark outside.

A photoresistor like leds and solar panels consists of semiconductors. They all turn on at dark off when there is sun. Photocells have been used since the mid 1900s in light meters while solar cells have only become popular since 1990. This component is useful in some projects such as a solar panel light follower or home automation to create a smart lamp that only turns on when it is dark or to set up an alarm with a laser diode.

A solar tracker aims to increase energy generation by pointing the pv panel straight to the sun providing more light to it. Despite the energy required for the control system the comparison between a static panel and the other with solar tracker represents a 15 average increase of generation for the one with solar tracker.
