The solar panel is used to generate electricity by converting light energy into electrical energy. The conversion efficiency of a solar panel is inversely proportional to the size of it. Solar panels are made up multiple solar cells and the two types of solar cells that are used are mono-crystalline and poly crystalline.

It is device that determines when to turn on or off the lighting and charging. The controller prevents overcharging or undercharging of the battery. The device will transmit the energy generated by the solar panels to the batteries during the day and at night the controller will supply the stored power from the battery to the LED streetlight.\u003C/p\u003E\n\u003Cp\u003EA smart charge controller provides for an excellent energy generation, performance optimization and monitoring of each streetlight by cloud-based software.\u00A0 The use of a built-in communication network with a dedicated software assists for the control and proactive maintenance of the entire street light network.\u003C/p\u003E\n\u003Cp\u003EControllers are classified as either a simple ON/OFF control, Pulse Width Modulation (PWM) or a Maximum Power Point Tracking (MPPT) device. ON/OFF control is used to provide protection for the battery by preventing overcharging, undercharging or the reversal of current.\u00A0 PWM is used to control the current charging the battery and provides trickle charging. MPPT is implemented in street lighting systems for high efficiency battery charging.\u003C/p\u003E\n\u003Cp\u003EThe battery is the energy storage component of the solar streetlight as it stores electricity generated during the day and powers the LED lamp at night. Lead acid batteries or lithium-ion batteries are the two most common types of batteries that are implemented. Lead acid batteries have a life span of 3-5 years and a cycle life of 1500-2500 cycles but have the disadvantage of taking a significant amount of time to charge. Lithium-ion batteries have a greater energy density as well as cycle life and are used in integrated streetlights that require a long cycle life, high energy density and small footprint. These batteries are also advantageous as it has a good thermal stability, high charging efficiency and a short charge time.\u003C/p\u003E\n\u003Cp\u003ESolar streetlights implement LED technology as it delivers a much higher lumen whilst using less energy.

A panic that is initiated by darkness with the addition of smoke-filled corridors can cause stampedes, and confusion which can lead to an increase in injuries, or even a fatality.\u003C/p\u003E\n\u003Cp\u003E\u003Cfigure role=\u0022group\u0022 class=\u0022caption caption-img\u0022\u003E\n\u003Ca href=\u0022https://www.magnet.co.za/contactus.html\u0022\u003E\u003Cimg alt=\u0022Fig1\u0022 data-entity-type=\u0022file\u0022 data-entity-uuid=\u0022b4e045fc-4317-4401-bafd-375d08c4812b\u0022 height=\u0022365\u0022 src=\u0022/cms/drupal8-magnetgroup/sites/default/files/inline-images/a_1.png\u0022 width=\u0022885\u0022 /\u003E\u003C/a\u003E\n\u003Cfigcaption\u003E\u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 \u00A0 Figure 1 : How an Emergency Lighting System Operates\u003C/figcaption\u003E\n\u003C/figure\u003E\n\u003C/p\u003E\n\u003Cp\u003E\u003Cstrong\u003E\u003Cu\u003EEmergency Lighting Technologies\u003C/u\u003E\u003C/strong\u003E\u003C/p\u003E\n\u003Cp\u003EThe 2 types of technologies that exist for emergency lighting systems are the self-contained (SC) system and the central battery system (CBS).\u003C/p\u003E\n\u003Cp\u003EA self-contained emergency luminaire has its own battery to provide the required power.
