Understanding the Main Components of Solar Street Lights
Before the solar street light-making process is described, the six main components of the system must be fist presented. It is necessary to highlight that every element has an indispensable input to the functioning of the light
- Solar Photovoltaic (PV) Cell or Solar Panel: This is the core of the system working, as it absorbs sunlight and converts the same to electricity to enable the lamp to work.
- Solar Charge Controller: This instrument controls the voltage and current flow from a solar panel in respect of the battery so that it can neither suffer damage through over charge or deep discharge.
- Solar Inverter: This converts the direct current obtained from the solar panel into its alternate current that is meant to light the street lamp.
- Battery: Stores the energy that was produced all through the day to be utilized in the night.
- Street Lamp: The light source, generally LED bulb owing to it being of low energy consumption.
- Cables and Pole: Connects the system together, with the pole supporting the solar panel and lamp.
These components are readily available in the market, making it easier for anyone to start their own DIY solar street light project. You can know more about our solar lights by clicking on this detailed article.
Solar Street Light Design
1. Assess Power Consumption
The first step in how to make solar street light is to determine how much power your system will need. This requires assessing the amount of light required to cover the area. For instance, a small residential street may require a different amount of light as compared to a parking lot or a public park.
The lumen requirement (which is an intensity of illumination) will help you determine the specific kind of street light lamp to be used. Most solar street lights use LED bulbs because they provide a lot of light while consuming less energy.
Once you know the lumen output required, proceed to class the bulb. Eg. A 50-watt LED would be sufficient to light up a small street or passage.
To get the total watt-hours the system requires, take the wattage of the bulb and multiply it by the number of hours you would want the light on each night.
2. Calculate Battery Capacity
Next, size your battery according to the energy storage requirement of the system. The battery has to be sized such that it can be able to run the light during the night and also during the day when there is no sun and it is cloudy.
In this regard, let’s say that if a solar street light is using 600 watt-hours in a day and that is in the night time, then one requires a battery that can support that much worth. The same can be achieved when the size of the battery is computed by the number of watt-hours and dividing this value by the nominal voltage of the battery which is commonly 12V.
This means you’ll need a battery of about capacity 50Ah at least. However, to allow the system to function in periods when less solar energy is available, let the battery be slightly oversized.
When working with solar street lights, deep-cycle batteries are almost an absolute requirement since they are built for repetitive charging and discharging. These include lithium-ion, lead acid, selection of gel-cell batteries and others. Among these lithium ion has the highest longevity efficiency, less weight and greater energy efficiency.
3. Size the Solar PV Panel
The next stage of how to make the solar street light is calculating the dimensions of the solar panel. The panel needs to provide enough daylight energy input to fully load the battery for the night operations.
The maximum Ũc close to the modular batteries is achieved by multiplying the total woke hours of the bad debt by a loss factor (Since their system is not that perfect), this is usually in the range of 1.2 to 1.3.
For now, this is done to calculate the required watt-hours. A total of required watt-hours will be divided by the average number of peak sunlight hours available in your geographical region, for which you can roughly say that, if your area records direct sun exposure for at least 5 hours/day.
Thus you should get a solar panel of around 144Wp to cover your basic needs. In general, when it comes to how to make solar street lights, Do It Yourself enthusiasts will always confirm local sunlight information before heading straight to the panel size.
4. Select the Right Solar Charge Controller
The solar charge controller is a very important part of the overall solar system in terms of safety and efficiency. It controls the voltage and current from the solar panel to the battery so as to prevent both overcharging and over discharging.
There are two primary types of solar charge controllers:
- PWM (Pulse Width Modulation): PWM (Pulse Width Modulation): Low cost but not so effective in performance. Best for small scale or less sophisticated systems.
- MPPT (Maximum Power Point Tracking): More costly but highly effective. It modifies the energy from the solar panel in order to reap as much as possible.
To choose the right controller, ensure it matches the voltage and current output of your solar panel and battery. As a general rule, pick a charge controller that can handle the highest possible current generated by your solar panel.
5. Determine the Angle of Tilt
Tilt angle is the most significant parameter affecting solar energy absorbed by the solar street light. Most tilt angles for installed solar panels hovers around its geographical latitude. Increasing the angle helps improve the solar panel efficiency, for the case during winters when the sun is lower.
Solar Street Light Optimization
It is essential to optimize every constituent towards achieving efficiency and cost-effectiveness for your solar street light system. This includes energy-efficient lighting considerations, battery selection, minimal losses in wiring and more. Learn about the working of solar street light by clicking.
1. Use Energy-Efficient Lighting
In order to optimize your solar street light system, the solution lies in the use of LED lights. This is because up to 80% energy is conserved as compared to other kinds of lighting sources like incandescent or halogen. Well made LEDs can also be used for a long time, lasting for about 50000 hours which translates into less maintenance costs over time.
In your DIY project, utilizing a high-lumen LED, means well, bright illumination with the solar street light will be achieved without too much power loss.
2. Optimize Battery Performance
The type of battery you choose has a significant impact on the overall performance of your solar street light. As mentioned, lithium-ion batteries are an excellent option due to their higher energy density and ability to handle repeated charging and discharging cycles. However, they tend to be more expensive than other types like lead-acid and gel batteries.
To optimize battery performance:
- Choose a battery with a capacity slightly higher than your calculated requirement to account for cloudy days or other interruptions in solar generation.
- Regularly monitor the battery health to ensure it is holding a charge efficiently.
3. Minimize Energy Losses in Wiring
The solar street light system is also seriously less efficient due to inappropriate wiring and bad connections with energy loss. In order to avoid that, high-quality wires of the corresponding market. Proper insulation is important to avoid any short circuits, and energy loss as much as possible.
Also, it is worth mentioning that energy loss can be decreased by decreasing the amount of wiring runs, especially during the connection of the solar panel to the battery.
4. Choose High-Efficiency Solar Panels
To further optimize the energy generation in your solar street light, use high-efficiency solar panels. Monocrystalline panels are widely regarded as the best choice because they offer higher conversion efficiency, especially in low-light conditions. Polycrystalline panels are also effective, but they generally have a lower conversion rate.
By choosing a high-efficiency panel, you’ll ensure that your solar street light generates more electricity per square meter, maximizing the energy captured during daylight hours.
5. Introduce Smart Control Systems
Smart technologies are also incorporated into sophisticated solar powered lights for better management of energy. Attaching motion sensing or light sensing devices to the system makes it possible for the lights to utilize only the necessary energy by adjusting its intensity in relation to the external conditions, for example the presence of pedestrian traffic and vehicles.
If you want to consume unnecessary power in your DIY project, you can use smart features which will save you the use of electricity and thereby the operational time of your solar street lighting will be increased per day.
