While solar lights generate their own power, it’s prime value is a much lower install cost. For a wired solution, the minimum cost of trenching for wires and a connection to the electrical grid is $50 a foot. This per foot cost can quickly increase depending on the terrain.

Over time, solar solutions are proven to be much more cost-efficient than grid-connected lighting. Installation of a PV streetlight doesn’t require any major work, such as groundwork, trenches, cable laying or electrical cabinets. Our solutions don’t need any maintenance for the first 10 years.

What’s more, by choosing streetlights running on green energy, there’s no more electricity bills. Together, these savings make solar streetlights much more competitive than their conventional, grid-tied counterparts. Today, the return on investment is very quick on some projects and immediate on others.

Off-grid solar street lights are entirely self-contained, making them ideal for isolated locations, without all the costs of cabling and grid connection. Also called photovoltaic or PV streetlights, they’re quick and easy to install, with no earthwork or trenches needed, allowing you to avoid the disruption and cost of trenching and remediation for electrical wires, so the range of possible applications is virtually limitless.

The key difference between led street public lighting and solar street lighting is their power source. Solar street lights use renewable energy. And because solar energy is free and will never run out, solar-powered led street lights are an ecologically friendly, cost-efficient and completely autonomous solution. They’re a perfect fit with the energy transition led by the government. Solar lighting also offers better availability, since it’s not affected by power outages.

If you’re looking at providing lighting for an outdoor space like a park, parking lot or pathway, solar is particularly well suited when:

The location would require a costly connection to an electrical grid
The install location gets at least 2 hours of direct sunlight a day
Lighting design specifications are within IES recommendation requirements

To recap, the key benefits of solar lighting are:

– no civil engineering, trenches, no wiring, grid connection or electrical cabinets
– no electricity bills & risk of blackouts.
-50% reduction in install cost
– 100% green energy & a smaller carbon footprint
– no maintenance for the first 10 years

During the daytime,the solar panels on top of the pole absorb the solar energy, turn them into electrical energy via a solar charge controller and store it in our Lithium-ion battery system, the smart battery gets recharged.. With PV light control technology, when dusk approaches, the built-in dusk sensor prompted the streetlight to turn on, after sunrise or at dawn, it switches off.

How does solar street light working ecoolpower ECOOL POWER

The level of lighting power is adjusted as part of the project to meet the specific requirements of each customer. For example, it can be set to produce brighter lighting at nightfall and in the early morning, with a lower level of illumination in the middle hours of the night to limit light nuisance and pollution. You can also customize with sensor dimming function as your project requirement.

EcoolPower®’s solar streetlights provide guaranteed lighting 365 nights a year, whatever the weather.

Here’s process:

  1. Design and Engineering: The process begins with the design and engineering of the solar street light. This involves creating detailed plans and specifications for the various components, including the solar panels, LED lights, battery storage, and housing.

  2. Component Procurement: Once the design is finalized, the manufacturer procures the necessary components from suppliers. This may include high-quality solar panels, LEDs, batteries, controllers, sensors, and other electronic and mechanical parts.

  3. Solar Panel Production: Solar panels are typically manufactured separately by specialized facilities. The panels are made using silicon cells, which are assembled into modules and encapsulated in protective materials such as tempered glass and aluminum frames.

  4. Battery Assembly: Battery packs for solar street lights are assembled using rechargeable lithium-ion or lithium-ion phosphate (LiFePO4) cells. These cells are connected in series or parallel configurations to achieve the desired voltage and capacity.

  5. LED Light Production: LED lights are manufactured separately and then integrated into the solar street light assembly. LED chips are mounted onto circuit boards and encapsulated in heat sinks and lenses to ensure optimal performance and durability.

  6. Controller and Sensor Integration: The control and monitoring components, such as charge controllers, light sensors, motion sensors, and programmable timers, are integrated into the system to regulate the charging and discharging of the battery and control the operation of the LED lights.

  7. Assembly and Testing: The various components are assembled into the final solar street light unit. This includes mounting the solar panel on top of the light fixture, connecting the battery pack and LED lights, and installing the control electronics. Each unit undergoes rigorous testing to ensure proper functionality, performance, and durability.

  8. Quality Assurance: Throughout the manufacturing process, quality control measures are implemented to ensure that each solar street light meets the highest standards of quality and reliability. This may include inspections, testing, and certification by regulatory authorities.

  9. Packaging and Shipping: Once the solar street lights pass quality assurance checks, they are packaged and prepared for shipping to customers. Proper packaging is essential to protect the units during transit and ensure they arrive in perfect condition.

  10. Installation and Maintenance: Finally, the solar street lights are installed at their designated locations, typically on poles or mounting brackets. Regular maintenance and servicing may be required to ensure optimal performance and longevity of the solar street light system.

  1. Aluminum: Aluminum is commonly used for the housing or casing of solar street lights due to its lightweight, corrosion-resistant, and durable properties. It provides protection for the internal components against environmental factors such as rain, humidity, and UV exposure.

  2. Tempered Glass: Tempered glass is used to cover the solar panels in solar street lights. It is highly transparent, scratch-resistant, and able to withstand harsh weather conditions, ensuring maximum sunlight absorption while protecting the solar cells from damage.

  3. Stainless Steel: Stainless steel is often used for mounting brackets, poles, and hardware in solar street lights. It offers excellent strength, corrosion resistance, and longevity, making it suitable for outdoor applications where exposure to moisture and environmental elements is common.

  4. Polycarbonate: Polycarbonate may be used for lens covers or diffusers in solar street lights. It is lightweight, impact-resistant, and UV-stable, providing protection for the LED lights while allowing for even light distribution and minimizing glare.

  5. Silicon Cells: Silicon cells are the key component of solar panels, responsible for converting sunlight into electricity. These cells are typically made from high-quality crystalline silicon or thin-film materials, encapsulated in protective layers to enhance durability and efficiency.

  6. Lithium-ion Batteries: Lithium-ion batteries are commonly used in solar street lights for energy storage. These batteries are lightweight, compact, and offer high energy density, allowing for efficient energy storage and prolonged battery life.

  7. LED Lights: Light Emitting Diodes (LEDs) are used as the light source in solar street lights due to their energy efficiency, long lifespan, and high brightness. LEDs are typically housed in durable casings made from materials such as aluminum or polycarbonate.

Yes. All of our solar lights turn on at dusk and turn off at dawn by default.

12hours at night, 3-5 backup rainy days

Yes,Our solar lights have the capacity to stay on all night provided they get an average of 2–3 hours of direct sunlight a day and their lighting profile is set to stay on all night. For times when conditions are less ideal, we have incorporated adaptive capabilities to ensure that the lights adjust their output so that they can stay on all night, every night.

Yes, all of our solar light equiped with microwave sensor technology, when it detect any movement objects, illumination levels will automatically be regulated from a ‘dim-mode’ to ‘full-brightness. Detect distance up to 15 meters, more accurate and sensitive.

What’s the difference between Motion sensor and PIR sensor?

Microwave sensor also called radar sensor, works by emitting high-frequency electric wave and detecting people movement.

PIR sensor works by detecting environment temperature changing, which usually is 3-5 meters sensor distance.

Yes, each solar lights comes with a remoter which can be use for switches different working mode, we have 4 working mode can choose from

Yes, the lighting profile setting at the time of order will be programmed at the factory. A lighting profile can be changed for luminaires at any time through our big remoter ( only for technical person use).

Our fixtures’ estimated useful life is 15–20 years. PV module guarantees optimal power delivery for 25 years.LifePO4 battery lifetime 10year,after 15 years,only replace battery,cheap cost. 

Our high-performance lithium batteries have a typical useful lifespan of 8–10 years.

During storage, lithium batteries will slowly discharge but should remain usable for a long time. Our lights’ adaptive capability will recharge a discharged battery in most circumstances by simply installing our light in a sunny location. When you connect the battery, you will see one of three scenarios, the light illuminates on for about 20 seconds, indicating a high charge level, the light flashes three times, indicating a low charge level,
or the light does not illuminate.

If you see either the steady illumination or the flashes, the light will easily charge itself in the bright sun. If the light does not illuminate at all, the battery is likely very low and may need recharging. 

Our lights work best with 2–3 hours of direct sunlight. Without this, all of our solar-powered lights are equipped with our innovative Solar Lighting Controller (MPPT). The smart controller in each light is self-learning which allows the lights to predicatively adapt to their surroundings, providing a level of lighting performance and reliability unmatched in other solar products. A brief conversation will determine if we can provide the lighting levels you require.

Unlike most solar lights, our Smart control system of solar lights learn and adapt to its environment and therefore have the ability to predict and set the appropriate reserve levels to maintain good operation in adverse conditions. Under worst-case scenarios, the battery’s “autonomy” – its ability to operate without a re-charge – would be approximately 7 days.

Yes, our lights are designed and constructed to resist damage from vandalism. Most of our systems are designed for 145 mph winds. In hurricane zones, we’ve created systems that can handle winds up to 180 mph

Yes, our lamp housing material is all die-casting aluminum, anti-rust, anti-corrosion

The mounting height for luminaires will depend on the area to be illuminated and wind zone. Please refer to the installation height recommendation of each model on specification.

This varies by project. Generally, we recommend spacing luminaries at a distance approximately 5 to 6 times the mounting height. For example, luminaires mounted on a 16-foot pole would be spaced 80 to 96 feet apart. Please refer to the installation distance recommendation of each model on specification.

Yes, we can provide IES files for your project to do Dialux simulation

The right lighting distribution will depend on the goals and specifics of your project. Normally Type II for road lighting, Type III for area lighting. We’d be happy to discuss what would work best.

Absolutely! We’re always happy to talk about what light would be most suitable for your project. 

We find that it typically takes about 5-7 minutes to install solar street light, solar bollards lights, solar flood light and 3-5 minutes for our solar garden lights

No. Because our lights are not tied to the electrical grid and they’re low voltage, it’s not required to have an electrical contractor.

Our lights have been designed to be easy to install, especially compared to both wired and other types of solar lighting. This is because:

Solar does not require a connection to the electrical grid, eliminating the need for trenching.
Our lights are integrated self-contained. This means that no assembly is required and there is no need to run wiring through the mounting pole from the solar module to the light.

We recommend concrete footings for luminaire poles and some solar garden lights that are mounted on the wall by using expansion screws.
