What is a solar LED street light?

Solar LED street lights are lights made of a crystalline silicon PV panel (power supply), smart controller, lithium or lead-acid battery (stock power), higher LED source and other components. A special PIR sensor can provide smart control capabilities or multi-function extension.

How do traditional light sources and LED light sources compare?

LED lights are 30-50% more efficient than most traditional street lights.

What are the advantages of the all-in-one solar street light?

The all-in-one solar street light features a more efficient mono PV panel, long lifespan LiFePO4 lithium battery, brighter brand LED, smart controller and PIR sensor in one cabinet. The AE Series is easy to install — it takes two workers only five minutes to finish installation and no heavy equipment is required.

What is the evaluation index of roadway illumination?

1. Car lane: average illumination, illumination uniformity and lengthways uniformity, glare limit, surround ratio and inductivity
2. Sidewalk: average illumination, mix illumination and vertical illumination

How do solar PV panels work?

PV Panels are made of a semiconductor material like silicon, along with phosphorous and boron which create conductivity within the cell and activate the movement of electrons. When activated by the sunlight’s energy, the electrons move across the cell and into the electrical circuit attached to the solar panel.

How much shading is too much for solar photovoltaic panels?

Shading a photovoltaic system dramatically decreases its output. Just shading the bottom row of wafers alone amounts to an 80% reduction in efficiency.

What are LEDs?

LEDs are light-emitting diodes, or electronic components that produce light by converting electrical energy directly to light by the movement of electrons within the material of the diode. Because LEDs are highly efficient, they are beginning to replace most conventional light sources.

Why is LED technology called solid-state lighting?

The term solid-state lighting is used because the electronics produce light directly from solid materials in which the electrons are embedded. This is unlike other technologies; for example, fluorescent technology requires a gaseous discharge medium to initiate production of light.

What makes LEDs more robust than other light sources?

LEDs have no gases, filaments or other moving parts. They provide light through a one-step process that takes place within the diode. You don’t have to worry about broken glass or other parts breaking or coming loose.

What are the advantages of switching to LED?

LEDs have no gases, filaments or other moving parts. They provide light through a one-step process that takes place within the diode. You don’t have to worry about broken glass or other parts breaking or coming loose.

What is a controller?

Controllers are very important for solar street lights because they can remotely turn lights on or off. Some modern controllers are programmable so the user can decide the appropriate amounts of charging, lighting and dimming.

What type of controller should I use with high voltage panels?

The only way to get full power out of high voltage grid tie solar panels is to use an MPPT controller. Since most MPPT controls can take up to 150 volts DC (some can go up to 600 VDC) on the solar panel input side, you can often series two or more of the high voltage panels to reduce wire losses or use smaller wires. With the 175-watt panel mentioned above, putting two of them in a series would give you 66 volts at 7.6 amps into the MPPT controller, but the controller would convert that to about 29 amps at 12 volts.

What’s type of battery do these lights use?

A lithium-ion battery is a rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.

How long does the battery last?

Normally five to eight years. If you are using double batteries interactively, they would have an even longer life.

What are the installation requirements?

1. Protect the PV panel from sharp/hard objects
2. Clean the PV panel to maintain its conversion efficiency
3. Avoid sheltering or shading the PV panel
4. Make sure the PV panel faces the sun in order to absorb maximum energy

Is it easy to maintain the all-in-one solar street light?

The all-in-one design with modular structure is easy to check, maintain, and replace as necessary.
