With the increasing threat of power outages from weather-related events or grid failures, emergency lighting has become essential for both homes and businesses. One solution to mitigate the risk of darkness during these events is the solar powered emergency lighting system. This article will provide a detailed overview of the system, including its components, benefits, considerations for selection and installation, and some leading models in the current market.
## Components of a Solar Powered Emergency Lighting System
The central components of a solar powered emergency lighting system include solar panels, LED lights, a battery for energy storage, and a control circuit.
Solar panels are responsible for converting sunlight into electricity. The size and number of panels required depend on the number of lights to be powered and the magnitude of sunlight available.
LED lights are chosen for their longevity and energy efficiency. These lights have longer lifespans and lower energy consumptions compared to conventional incandescent or fluorescent bulbs.
The battery is a crucial component that stores the produced electrical energy which can be used during outages. It is generally of rechargeable type – lead-acid or Lithium-ion – and its capacity determines how long the lights stay on during a power outage.
Lastly, the control circuit serves as the system’s brain. It manages the flow of electricity, switching between normal and emergency power sources, and coordinating the system’s charging and discharging processes.
## Benefits of Solar Powered Emergency Lighting
There are numerous benefits associated with solar powered emergency lighting. These systems promise reliable and instant backup lighting during power failures. Being powered by the sun, they offer a sustainable energy solution, reducing carbon footprint and dependence on grid electricity. They may also provide cost savings over time, reducing demand on primary energy sources and thereby lowering monthly energy bills.
Another significant advantage lies in its grid independency – being off-the-grid, these systems continue to operate even when there’s an entire grid failure, making them effective during extensive blackouts, storms, or natural disasters.
## Selecting and Installing a Solar Powered Emergency Lighting System
When choosing a solar powered emergency lighting system, several factors must be considered. First is the system’s capacity, which should be guided by the required duration of light and intensity.
Second, examine the solar panel’s effectiveness. Since the system’s performance relies on sunlight conversion, it is necessary to choose high-efficiency solar panels. Similarly, the battery’s quality and capacity must be substantial enough to cater to the specific requirements.
Lastly, the control circuit must be of high quality, ensuring immediate and seamless transition between regular and emergency power sources.
Installation should be undertaken by a professional to ensure optimal lighting coverage and solar panel orientation for maximum solar absorption. The panels should ideally be north-facing (in the Southern Hemisphere) or south-facing (in the Northern Hemisphere) and installed at the optimal tilt angle based on the location.
## Market-leading Solar Powered Emergency Lighting Systems
Several models of solar powered emergency lighting systems have stood out in the current market due to their efficiency and reliability.
The BioLite SolarHome 620 is a portable kit perfect for off-grid households. It includes a 6W solar panel, control box with a built-in radio and MP3 player, multiple hanging lights, and a motion sensor light.
Goal Zero’s Lighthouse 400 Lantern is notable for its built-in solar panel and hand crank. Additionally, it can also be charged on a traditional grid, ensuring versatility and dependability.
The RunningSnail Solar Crank NOAA Weather Radio for Emergency is another excellent choice with its radio, 2000mAh power bank, and 1W LED flashlight. Its multiple charging options ensure users will never be left in the dark.
SunKing’s Home 60, a robust and versatile model, contains three bright lights, a portable radio, and a motion-sensing security light. The system is built to last for at least five years and delivers up to 24 hours of light on a single day’s charge.
While these are but a few examples, the market is teeming with innovative solar powered emergency lighting systems designed to suit various needs, from home use to remote cabins, RVs, and campsites.
Solar powered emergency lighting indeed offers a practical solution for uninterrupted lighting during power outages. By harnessing the ubiquitous sun, it not only provides a sustainable solution but also promotes energy independence, helping citizens to face any power disruptions without fear. With careful selection based on requirements and professional installation, a solar powered emergency lighting system indeed can be a reliable asset for both households and businesses.
