Solar Street Lights
Solar streetlights work by using daylight to charge the battery cells built into the light unit. When night falls the lights automatically come on using energy charged into the batteries in the daytime. There is no requirement for any mains electricity to be wired to the lighting columns.
ALL IN ONE (TWO) SOLAR STREET LIGHT
Integrated Solar Street Light 40W-120W
All In One Solar Street Light 30W-120W
Solar Road Light All In One 60W-100W
Solar Street Lamp 30W-120W
All In Two Solar Street Light Sys
Solar streetlights require no mains electricity; the saving on installation is vast as costly groundwork to lay mains cables is not required. Once installed there are no running costs associated with the solar units.
Do solar streetlights work in bad weather with no sunshine?
Yes, ExpoTech Solar streetlights work all year round even in the Northern Hemisphere. The light units have been designed and developed for the Bangladeshi market and the large solar panels and high-capacity batteries enable the light units to work through the winter months. What is the expected lifespan of a solar streetlight?
The led units in the lights have a service life of 100,000 hours, the battery system has a warranty of 5 years and the solar panels 10 years.
Can I change and control the light unit myself?
ExpoTech Solar streetlights can be programmed and set to different parameters depending on your requirements. They can be set to come on at dusk for a period of time or to come on all night, there are many options. This can all be done via an app on your phone.
What cost savings can I expect to make between a solar and mains streetlight?
Solar streetlights can be installed in one step, no need to dig trenches, lay cables and backfill, so there is a considerable saving on the initial installation. There is no need to increase power capacity in the area either. Once installed, ExpoTech Solar streetlights have no running costs.
How does the light unit know when to turn on?
The light units are fitted with dusk-to-dawn sensors so they only operate when night falls.
Is there any maintenance required on solar streetlights?
We recommend that the solar panels are cleaned and battery units checked annually. We can offer a service agreement to carry this out.
Can solar streetlights be fitted anywhere?
One of the main advantages of solar streetlights is that they can be fitted anywhere, from roads to parks, farms to marinas; the list is endless. We offer a roof mount fitting and a surface mount unit.
Solar Floodlights
ExpoTech can provide different types and functions of solar street lights or solar powered parking lot lights, such as wind solar hybrid street light, AC/DC hybrid solar street light, motion sensor solar street lights, human body induction control solar street lights, timer dimming solar street lights, etc. . Additional accessories for solar street lighting systems such as foundation cages, street lighting poles, cables, etc. are available. These solar street lights can be widely used as garden lighting, road lighting, school campus.
Structure of Integrated Solar Streetlight
1. LED Module
Using high-efficiency Lumileds LED chips, the luminous efficiency is up to 205LM/W, the same luminous flux, and the power can be reduced by 50%, which greatly reduces the overall cost.
2. Lithium Battery
Integrated solar street light usually use lithium batteries as energy storage. Lithium battery is divided into ternary lithium batteries and lithium iron phosphate batteries (LiFePo4 batteries), Lithium battery is a key component in solar street lights, and the cost is also the highest.
3. Solar Controller
At present, most of the solar street lights on the market use PWM controllers, which are relatively cheap. With the continuous development of technology, more and more solar street lights use high-efficiency MPPT controllers, which are relatively expensive.
4. Sensor device
For integrated solar street lights, sensor devices generally include motion sensors, also known as microwave sensors, human body sensors, also known as infrared sensors, and radar sensors.
5. Solar Panels
Solar panels are divided into monocrystalline and polycrystalline solar panels. the conversion efficiency of monocrystalline is higher and the price is higher, polycrystalline solar panels are a little cheaper but with low efficiency, now most integrated solar street lights use mono solar panels.
Why Choose Solar Led Street Lights?
The solar street light is a new type of road lighting fixture. During the day, monocrystalline or polycrystalline silicon solar panels convert solar sun energy into electricity, which is stored in maintenance-free valve-sealed batteries or lithium batteries through the solar controller, and at night, the solar controller controls the discharge of the batteries for the LED lights to work. It will bring many benefits.
- Energy saving
Convert solar energy into electricity to drive LED street lamps to work. Solar energy is inexhaustible.
- Safety
Solar street lights are powered by 12-36V solar panels, which are within the safe voltage range and will not cause electric shock accidents to people, making them safer to use.
- Flexible application
Off-grid solar street lights do not require a grid power supply and can operate autonomously as long as there is sunlight, which is very flexible, so they can use even in remote power-deficient areas.
- Less investment
The solar street light system not need power supply equipment, can be completely automated operation, no need for personnel management, so low operation, and maintenance costs.
