What is solar street light?
Solar street light is a street light that uses crystalline silicon solar cells for power supply, maintenance-free valve regulated sealed battery (colloidal battery) for storing electric energy, ultra-high bright LED lamps as light source, and controlled by intelligent charge/discharge controller, used to replace traditional public electricity lighting.
How does the solar street light work?
Under the control of the intelligent controller, the solar panel absorbs solar light and converts it into electric energy after sunlight irradiation, and the solar cell module charges the battery pack during the day, and the battery pack provides power to the LED light source at night to realize the lighting function. The DC controller can ensure that the battery pack is not damaged by overcharging or over discharging. It also has the functions of light control, time control, temperature compensation, lightning protection, reverse polarity protection, etc.
What are the benefits of solar street lights?
Easy to install
Solar street light is simple and easy to install without complicated new wiring. It only needs a concrete base and a battery pit. The installation does not require a lot of labor, material, and financial resources.
Energy saving, and environmental protection
Solar street light can convert sunlight into electricity without using electricity. No pollution, no radiation, in line with today’s environmental protection concept.
Safe and durable
Traditional street lights may have safety hazards due to construction quality, aging materials, power supply disorder, etc.; while solar street lights do not use AC power, there will be no safety hazards. Today, most solar modules on the market are stable for at least ten years due to mature manufacturing technology. They can generate electricity for twenty-five years or even longer.
High technology, and low maintenance cost
Solar street lights are regulated by solar charge controllers, which can adjust the light intensity according to the natural brightness and people’s needs. In remote areas, traditional street lights have high maintenance costs. While solar street light only needs periodic inspection, the maintenance cost is relatively low.
What are the advantages of solar street lights?
Some other significant advantages of solar street lights are mentioned in the following mentioned points.
Solar street lights IP66/IP67 waterproof, weatherproof, and low glare and insect infestation rate.
The solar panels in these lights convert solar energy into electrical energy, stored in the built-in battery for dusk to dawn lighting operation.
The main feature of modern solar street lights is the battery management system, which contributes to the presence of motion and nighttime sensors.
The system performs at medium brightness for the first five hours of the night. The light intensity gradually decreases until dawn or the PIR sensor is activated by human activity.
With an intelligent lighting option, it automatically turns on full brightness when it senses human movement within a specific radius of the luminaire.
Solar outdoor luminaires require little to no maintenance compared to traditional street lights.
The Green Alternative
In traditional lighting, people rely on the power grid for energy. During a power outage, there will be no light. However, sunlight is available everywhere and is abundant in many parts of the world. Sunlight is the world’s leading source of renewable energy. The upfront cost may be a little more. However, once the installation is complete, the cost will be less. In the current scenario, solar energy is considered to be the cheapest source of energy.
Since it comes with a built-in battery system, you can power your street without sunlight. In addition, the batteries are recyclable and do not harm the environment.
Cost-effective solution
Solar street lights are cost-effective. There is not much difference between the installation of off-grid solar and grid-connected systems. The key difference is that the solar street light will not be metered. Installing meters will contribute to the final cost. In addition, trenching the grid will increase the cost of installation.
Safe Installation
When installing a grid system, some obstacles, such as underground utilities and root systems, may cause interruptions. If there are many obstacles, electric trenching will be a problem. However, you will not encounter this problem when using solar street lights. Users just need to erect a light pole at the place where they need to install the solar street light.
Maintenance-free
Solar street lights are maintenance free. They use photocells, which greatly reduces maintenance requirements. During the daytime, the controller keeps the lamps off. When the panel does not produce any charge during the dark hours, the controller turns the luminaire on. In addition, the batteries have a durability of five to seven years. Rain will clean the solar panels. The shape of the solar panels also makes them maintenance free.
No Energy Bill
With solar street lights, there is no electricity bill. Users will not have to pay a monthly electricity bill. This will make a difference. You can use the energy without paying a monthly energy bill.
