ALL-IN-ONE LED SOLAR STREET LIGHTS
A standalone solar photo-voltaic compound lighting system is an outdoor lighting unit used for illuminating a compound or an open area.
Recent advances in LED lighting have brought very promising opportunities for application in compound lighting. Combining LED’s low power, high illumination characteristics with current photo-voltaic (PV) technology, PV powered street light utilizing LED has become a norm in many places. In today’s application, most of the common High Intensity Discharge (HID) lamps, often High Pressure Sodium (HPS) lamps are being replaced by more low powered Light Emitting Diode (LED) lamps. |
Integrated LED solar street lights with solar panels (last for 25yrs), LED bulb (last for 50,000hrs) and latest Li-Ion batteries (last for 2,000 charging)
Sun charges the solar panel during daylights and store the energy in battery bank for use at nights. If no sunshine, batteries will energize the LED bulbs for maximum of 3 days. Wide ranging applications covering all lighting requirements from compound to highway lightings. Independent units. No interconnecting underground cabling and substations More that 70% reduction in CAPEX and OPEX as compared to normal grid lights Once installed, ZERO monthly TNB bills |

components
A basic solar powered LED compound light system components are:
The Solar Panel will provide electricity to charge the battery during day time. The battery’s charging is controlled by a charge controller. The operation of the LED bulb is controlled by a control circuit either by using sensors such as Light Dependent Resistor (LDR) or voltage or current sensor. All these components will be fixed on a pole. |

checklist prior to installation
- Check whether electrical power already exist: Bringing in standard power can be very costly.
- Get dimensions of the area: Knowing how large an area needs to be lit is important.
- What are your light level requirements: Do you need bright lights or lower light levels?
- Where is the installation location: Knowing the sun hours available makes sure the system is sized properly.
- How long does the light need to be switched on: Do you need them all night or only for a couple hours?
- What type of fixtures: Do you want something standard or more decorative? Both options are available.
- Wind load ratings: Is the installation in a hurricane / strong storm prone area?
- What is the ambient temperature: For the LiFePO4 battery of the solar powered street lights, the working temperature is between -20°C and +60°C.
- No obstructions that may leave shadow on the solar panel. With shadow on it, the solar panel may become open circuit and won’t work.
- No other light sources around. The other light sources around the solar street light may influence the light sensor.
