Solar Street Light System Varieties
Solar-powered lights are becoming more and more popular these days. These stunning solar street lights can be seen on highways, public places, and even inside homes. You may be considering to purchase a company that is fitted with standard electric street lighting and desire to convert it into a green company; for reducing maintenance costs. Furthermore, apart from the benefits of energy conservation and lower costs, solar street lights are the ideal solution for those areas that completely lack electricity.
The complete solar street light set comprises of the following:
- A solar panel
- A LED light
- A battery and a battery box
- Light controller
- A light pole or post
Off-grid systemMany solar light projects are targeting those areas where it’s not feasible to undertake electrical wiring due to higher overall installation costs. In an off-grid system, each light pole is equipped with an independent unit; consisting of a solar panel, battery, LED light, and light controller. This unit can be conveniently placed in any place that has sufficient exposure to sunlight.
An off-grid solar-powered street light operates by charging a battery during the daytime; the power thus stored will then be utilized at night for the switching on of the solar LED light. The solar panel functions as a photocell, switching the light fixture to ON/OFF positions. Although this system is more costly, it does offer free energy for the total lifespan of the systems, which is normally 30 years or more. However, the batteries require replacement every 5-7 years.
Grid-tie systemThe grid-tie solar systems are the most favored by homes and businesses. They don’t require batteries; making use of common solar inverters and are linked to the public electricity grid. Any surplus solar power being created is transferred to the electricity grid and customers benefit by receiving a feed-in-tariff (FiT) or credits for the transfer of energy. The size of the solar panel to be installed here will be determined by the required amount of power generation during the day. A local electrical contractor can assist with this; the local power company can install a special device to track power generation. In addition, using energy-efficient LED fixtures can contribute to a further reduction in costs.
Hybrid systemModern hybrid systems are a combination of solar and battery storage; they are currently being sold in various forms and configurations. These systems are either off-grid solar with backup power from the utility company or grid-tied solar with a surplus amount of battery storage. Owing to the decline in battery storage costs, systems linked to the electricity grid can benefit from battery storage. This enables solar energy produced in the daytime to be conveniently stored and used at night. When all the stored energy has been used up, the grid is present to take over, permitting effective usage of both power sources. Moreover, hybrid systems are capable of battery-charging using lower-cost, off-peak electricity.
Battery backup systemsIn this, power is generated for the batteries, the batteries are not as large as the ones for complete off-grid systems, with any surplus power being fed into the grid. The batteries can be utilized to switch on lights for a fixed period of time at night, after which grid power takes over, or they can be put to use in the event of a power blackout in the area; the perfect solution for locations lacking dependable grid energy. Similar to off-grid systems, this system can offer more storage using a trickle charger and a larger battery backup, and only be utilized when there is an occurrence of grid blackouts. This system consists of automatic motion sensors for adjusting the LED light’s brightness. This automatic control of brightness, in accordance with movement detection in the area surrounding the light, helps to save energy. The solar street light has a longer backup time, its lithium-ion battery is maintenance-free with a better lifespan. The light is easily installed due to its compact size and the automatic dawn to dusk working function requires minimal maintenance after installation.
The sun is a renewable, dependable, and pollution-free power source. Solar-powered lighting systems offer the perfect solution for the illumination of regions where electricity is unavailable. Apart from this, these lights are highly beneficial in urban areas as they lower dependency on conventional power and favor the advancement of green energy. Solar-powered streets offer long-lasting solutions with the acquisition of an effective and affordable lighting system.
