Typically, solar lights are installed in open areas, whether in a park, square, parking lot, or driveway. This means that you will most likely have people around you while installing your solar street light. It is vital to pay attention to the task and also ensure the safety of everyone around by creating a barrier to mark your work perimeter.
This gear will go a long way in minimizing your risks of getting injured during the installation. It is also imperative to remove every form of jewelry or watch because they are conductors of electricity. They can hinder you from effectively installing your all-in-one solar street light. It is necessary to gather everything you need to complete the installation because it is not a project that you should stop midway. Your wires and metals can get damaged if you leave them exposed overnight.
Here are some of the things you need to put in place:. Typically, the weight of the solar street light pole will determine how much assistance you require.
Installing your all-in-one solar street light is simple, and you only need a few steps and tools. Follow the circuit diagram when you connect the light fixture to the controller. Connect and secure the light fixture to the lamp pole. Check installation and connections to confirm that everything is in the right place.
Make sure that wires and components are connected according to the electrical circuit diagram. Use a crane to erect the lamp pole. Ensure that the lamp pole is upright on the bottom plate. Fix and secure it with bolts. Place the controller inside the lamp pole , with the correct wires and leads properly connected to the controller. Check that the erected street light is working and behaving as expected. You have now successfully erected and installed Your Solar Street Light. Make sure to follow the instructions and safety guidelines to ensure a successful installation.
You may say we should increase the size of both battery bank and solar panels. Well, this sounds plausible in engineering respect, but when it comes to the project budget, this also means the raising of outlay significantly since the cost of battery accounts for a larger part. Then, why not adopt the ones with advanced technology, all in one solar street lights. All-in-one solar street lights are one type of integrated solar street lights, which integrates into a product the four main components: solar panel, light source, battery, solar energy cables , and solar controller.
Monocrystalline and polycrystalline solar panels are two different solar panels that are widely applied in the solar industry. Generally speaking, monocrystalline performs better than polycrystalline, especially in cold weather they have higher energy conversion rates than polycrystalline. To data, Sunpower monocrystalline solar panels can reach as much as So, Monocrystalline panels are installed in all-in-one solar street lights due to their limited size.
These solar panels act as the role of energy collecting and conversion, in the daytime, they collect energy from the sun and then convert them into electric power which will be stored in batteries as chemical energy. Suffice it to say, as light sources LEDs are prevailing among illuminating market, for their high performance in energy-saving.
It definitely can be counted as a new generation of lighting solutions. LED types vary in size and watts, such as , , , , to adapt to different applications. Furthermore, an aluminum heatsink is always applied to the rear side of the led modules to help dissipate the heat generated by LEDs. This is very important, for although manufacturers claim that LED has a lifespan of more than 50, hours, its light depreciation can be abnormally high if it is working at a temperature larger than 70 Celsius.
So we must make sure that the LED junction temperature is under 70 Celsius. Rather than car batteries, which are designed to discharge a large amount of energy in a short period of time, renewable energy industries prefer deep-cycle batteries , for their excellent characteristics in the enduring power supply, deep discharges, and far more cycle times, times, twice or three times more than that of car batteries.
Batteries cycle times are also affected by the depth of discharge DoD , we will talk more in Chapter 5. There are two main types of deep-cycle batteries that existed in the solar battery market: lead-acid and lithium.
What we have learned, from the comparison table above, is that LiFePO4 battery is more expensive, but its chemical substance inside is more stable, which makes it kind of high-temperature resistance, while ternary lithium battery is relatively low-temperature resistance, for its materials are more active and can work under 0 Celsius.
So, if your project is in the tropics, a LiFePO4 battery is recommended. But if the project is in northern countries, we advise ternary lithium battery. As the main functional component, MPPT solar charge controllers have some basic functions as below. The controller is always monitoring the voltage of the solar panel, which increases or decreases with the intensity of the sunlight. When it is lower than 5v, towards dusk, the control will switch on the LED lights.
And when it is towards daybreak and the voltage is larger than 5v, the LED lights will be turned off. The solar controller can also control the power output according to the time schedule, for instance, you want.
Commonly, a controller has around 5 time-slots you can use to set according to different requirements of projects. Time control is often used in conjunction with motion sensor control. By doing this, we can save a lot of energy to boost the duration of off-grid solar street lights and ramp up the days of autonomy. A controller can take action when it receives a signal from the motion sensor to increase LED brightness when someone is in the sensor area, and then revert to the former level of brightness when it moves out of the area.
Either overcharge or over-discharge can dramatically reduce the lifespan of batteries, although batteries modules themselves have this sort of protection, solar charge controllers usually have the same function analogous to that of battery modules. But be rest assured, the two are not conflicting with each other, for they function in different dimensions.
Infrared and microwave motion sensors are two popular types in all-in-one integrated solar street lights, the infrared motion sensor detects heat source movement, while microwave ones send microwave radar and receive the bounced signals to analyze the changes in bounced signals.
Our all-in-one solar street lights incorporate infrared types, which have a degree working angle and can detect a squat cone space under the lights. We do not prefer microwave ones, although they have a larger working angle, they are rather too sensitive and more likely to respond to some wrong movements, such as swaying trees, flapping birds, and fluttering flags. However, as integrated solar street lights, all in one solar street lights can also integrate some other functioning modules, such as Bluetooth, CCTV Closed Circuit TV , or even a wireless monitoring system, which enables end-users to monitor the status of each light or even to control every light by PC or mobile phone at any places where there are internet services.
First, the solar charge controller will turn off LED lights towards dawn once solar panel voltage rise to 5v, which is accounted for a little sunlight in the morning. When there is enough sunshine during the day, the solar panel will work together with the solar charge controller to collect the solar energy. Commonly, in a 12v solar system, with the effect of insolation, the voltage of its solar panel will rise to around 18v so as to charge the 12v battery bank.
Meanwhile, the solar charge controller will prevent overcharge to protect the batteries. When there is not enough sunlight towards dusk and solar panel voltage drops to a value under 5v, the LEDs will be turned on accordingly. As primary function, Time control is used to customize different brightness in different time slots.
For example:. In the past, why people do not tend to choose solar-powered street lights is due to three major reasons,. In those days, although LEDs had been on the market in commercial outdoor lighting for a few years, the technology was still not mature. Furthermore, since LEDs were newly developed at that time, the cost was rather expensive and the average man on the street could not afford to buy. The third reason is the solar battery. The lithium-ion battery has the longest lifespan as one kind of deep cycle battery, but they were not stable and would fail to work under 0 Celsius.
Thanks for the technological breakthrough in both the lithium-ion battery and LED lighting. Networked lighting can tender extra public security measures and diminish or light up dependent on specific conditions. As in the past, this is the expense of solitary road light. Envision 10 lights? All of a sudden, the reserves with solar are clear-cut.
In the skirmish of the lighting frameworks, innovation and development prevail. While conventional lighting frameworks may have triumph a few fights solar-powered street lights succeed the war for road light costs. The Secret Behind Solar Powered Street Lights Cost Solar-powered street lights are incredible for brightening regions without electricity, for example, parks, courtyards, gardens, streets, walkways, campuses, and above!
Energy invoices As a matter of fact solar-powered street lights assemble their energy from the sun, so there are nix energy costs!
