What Is A Solar Light And How Do They Work?

Many years ago, harnessing the power of the sun to solar lights sounded like speculative fiction. Solar panels, however, may now be seen on the rooftops of buildings and residences, as well as on-street lighting in some towns. This indicates that, with the proper optimization, solar energy may replace the current energy sources we have today. 

To avoid the negative impacts of climate change, the world is striving for more renewable energy. According to World Energy, the average annual worldwide solar radiation can provide the same amount of energy as 140 m3 of natural gas, 200 tonnes of coal, or a barrel of oil. In addition, solar lights, like conventional solar energy, are very efficient, so let’s know a bit about them.

What Is Solar Light?

The solar cell is the most significant component of solar light. The solar cell is the component responsible for converting sunlight into a direct electrical current. The solar cell is visible as a black panel at the top of a solar light. It is the photovoltaic solar panel that converts solar energy into light.

A solar cell comprises many layers of crystalline chemicals and silicone that combine to form layers of positively charged spaces and negatively charged electrons. As sunlight travels through the solar cell, it stimulates negatively charged electrons and forces them into positively charged regions. The photovoltaic effect is what makes solar lights operate. 

How Do Solar Lights Work?

How Do Solar Lights Work

When the sun shines, shines, a solar panel absorbs the light and converts it into electrical energy. The energy can then be saved in a battery or utilized right away. Most solar lights are designed to supply electricity at night, so they will either include a battery or connect to one. 

Given the availability of solar energy, the cell itself does not need to have an enormous capacity. Still, it should be highly durable to compensate for the problems of changing batteries in many areas worldwide.

Enough sunshine is required to charge the solar panel completely. This should not be an issue during the summer, as long as the lamp is situated to receive direct sunshine for most of the day. If possible, make sure that no trees or shrubs generate shade that might interfere with the solar light’s recharging.

However, a solar light may not receive enough sunshine during the winter to charge the battery sufficiently to stay lighted all night. This happens because the nights are longer, and the days are shorter in the winter, resulting in fewer hours of sunshine to charge the battery. Furthermore, snow typically falls during the winter, obstructing the solar cell and impeding charging throughout the day.

How To Make Solar Light At Home?

The photovoltaic solar cell is the most significant component of solar light. It is the component responsible for converting sunlight into a direct electrical current. It’s never been easier to make a solar light. Obtaining a solar light does not need any technical or electrical skills. You can follow our guidelines, and you’ll be fine.

Step 1: Collect Your Products

If you want to know how to make solar light, you will integrate various gadgets and equipment. You do not require raw materials as factories or industries do. You can’t build everything from scratch. As a result, purchasing spare parts and installation kits is the best option. The products you will need are;

  • Hot Glue.
  • Jar.
  • LED Lights.
  • Soldering Machine.
  • Battery Holder.
  • Solar Panel.
  • NiMH Battery.
  • Circuit Board.

Step 2: Prepare The Wires

Choose the wire and make sure it is perfectly sized. Before joining the wire, it must be precisely trimmed. A precise trimming will allow you to install the cable in the correct location. Cutting is also necessary for perfectly connecting various edges. Furthermore, you should be aware of the cable’s length from one end to the other.

Step 3: Put The Light On The Circuit Board

You must precisely attach the light to the circuit board. The light will be powered by the board via the connection you have previously placed. Before you finish, check the voltage to make sure you’ve connected it correctly. Check the connected ports and hubs as well to ensure safe functioning. When attaching the light to the circuit board, there is no tight connection.

Step 4: Connect The Circuit Board On The Battery Holder

Solar lights cannot be powered directly from solar panels, so you’ll need solar power inverters for that. The circuit must be connected to the battery. A technical aspect of building a solar light is touching the circuit to the battery. You must comprehend the input and output voltages. Depending on the type of connection, you must consider an inverter, cable length, and thickness. 

Step 5: Drill The Lid

Set the circuit board aside and grab the jar lid. Make a hole in the jar’s lid and take care not to set it on a surface that may harm it. Assuring that your hands are not too close together when drilling since you might injure yourself. The hole you drill must be in the middle of the lid for the panels to be sturdy and the red and black wires to fit correctly.

Step 6: Connect The Panel To The Circuit Board

The solar circuit board collects and supplies electricity from the solar panel to the circuit board. It’s straightforward, and the system will create and provide electricity to the lights automatically. However, before placing the solar panel in the sun, you must double-check all of the connections. 

Step 7: Attach All The Parts

You can use any waterproof adhesive that is appropriate for plastic attachment. To securely adhere the components together, use hot glue. Gently apply glue to the solar panel edge and firmly push the wires next to it to ensure a strong bond. Close the jar’s lid, and you’ve got yourself a solar light.

Step 8: Install The Switch

Special solar switches that operate well with both DC and AC output are required for solar lighting. A high-voltage switch is incompatible with solar panels and lights. You may have complete control of the light by switching between the solar light and the battery. When placing the switch with the solar light, try to maintain it in a readily accessible location.

Step 9: Select A Location

You now have a fully functional solar light in your hands. You may have chosen the location while making it, right?. So, just keep your solar light in place while you add the installation frame and screws with exact measurements. It is preferable to put them away from where they will spend most of their time.

Step 10: Test Your Solar Light

You should test the performance of any electrical equipment, especially solar electricity. To begin, it is critical to examine the solar panel’s energy output rate. Next, analyze the battery’s performance. Finally, you may evaluate the battery’s charging / discharging performance.

What Are The Benefits Of Solar Street Lights?

Solar LED street lights rely on the photovoltaic process, which converts sunlight into useable electrical energy in the solar cell. This is accomplished by pushing negatively charged electrons into positively charged regions within the cells. The benefits of solar street lights are;

  1. There will be no cabling, trenching, or metering.
  2. There are no power outages.
  3. In case of gloomy or wet weather, a battery backup is available.
  4. Distributed lighting and electricity – no single point of failure for increased security.
  5. With fast connect connectors, installation takes less than an hour.
  6. There will be no planned maintenance for up to 5 years.
  7. There is no need for transformers or meters.
  8. You may be eligible for grants and interest-free loans for technology.
  9. There is no continuous electricity.
  10. Controlled charging to extend battery life.
  11. Long-life PV modules come with a power generating capability of more than 25 years and a guarantee of ten years.

Final Thoughts

Please maintain the solar light clean at all times, avoiding dust and dirt buildup. If you want to use the solar light in your living space, dirt might prohibit it from illuminating it. The solar panel will also be shielded from direct sunshine, which is required to keep the solar light operating.
