Depleting natural resources, the looming threat of climate change, and inevitable increases in electricity costs mean that there is a desperate need for renewable energy sources. The sun at the centre of our solar system has been a source of light and heat since the dawn of time. Now thanks to improvements in photo voltaic technology, the sun has become a viable source of power through the conversation of solar radiation into electricity.
Since street lighting was the first major application of the electricity grid, it is only fitting that street lighting also light the path towards a future of solar powered lighting.
What is a Solar Light system?
A solar light system is the combination of lighting and solar power technology, whereby the electricity generated by the solar light system during the day
is then used to power the solar light system – providing light – during the night. This autonomous system frees the lighting from the electricity grid, allowing for more freedom to locate and install lighting where it is needed, in addition to forgoing the associated utility grid costs and fossil fuel source.
Solar Lighting Components
A solar light system comprises a number of key components including:
Solar Photo Voltaic Module: these are the solar cell panels you would no doubt already be familiar with. An assembly of photo-voltaic cells mounted together which convert the suns solar energy (electromagnetic radiation) into direct current electricity.
Charge Controller: before the generated electricity can be stored in a battery or used to power any luminaires, it passes through a charge controller. The charge controller is necessary to ensure that electricity within the system is properly regulated and maintain the health of the battery. The charge controller also allows the luminaire to be switched remotely and programmed for dimming.
Solar Battery: as the name suggests, this is where electricity generated from the solar panels will eventually be stored for powering the connected luminaires.
Luminaires: LIGMAN has a growing range of luminaires that have solar photo-voltaic modules integrated to various degrees from vertical solar poles, NATURE SOURCE post top module and a growing range of solar integrated bollards which represent the future of solar light systems.
