Today, all statistical vocabulary is about how to improve grid reliability during peak hours. The immediate solution for the grid is to cut off certain loads to keep it stable. One of them is street lighting, especially during summer. This paper proposes an energy-free street lighting system because there is no electricity demand from the grid. Proposal for a standalone
Solar Road Lights LED system.
The system consists of photovoltaic panels, a storage system, LED lights, a power conditioning system (PCS), and a controller that manages power direction and system operation. Compared to other lamps,
LED Solar Road Lights have many advantages in lighting applications. This is very efficient (very efficient lighting source) and cost effective (very long life compared to other lamps).
Additionally,
Solar Road Lights require a low DC voltage source to operate. The storage system will be charged during the day using available sunlight. On the other hand, at night, the controller will signal the system to connect the
LED Solar Road Lights for use. Since LEDs require a low DC voltage to operate, a simple DC-DC converter will suffice for this system, thereby reducing overall system cost. In addition, a low-cost microcontroller is proposed to handle the operation of the entire system. Applying this concept on streets such as towns, villages, and highways can reduce the total energy of HID lamps by more than 50%, allowing small photovoltaic systems to be used. With this
Solar Road Lights system, streets can be lit with lower power lamps, no operating costs, no CO2 emissions, no grid, and environmental protection. Furthermore, the proposed solution can address the urban, rural as well as highway peak load demand crisis.
