LED Solar Lights Buying Guide


There is no doubt that the emergence of LED solar lamps has brought great convenience to our life, not only longer service life, but also more low-carbon environmental protection. In this guide, we will describe in detail what LED solar lamps are and how to choose LED solar lamps.

  • What is LED Solar Lights?


    A solar lamp also known as solar light or solar lantern, is a lighting system composed of a LED lamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar photovoltaic panel.

    Difference between LED Solar Lights & Conventional LED Lights

    The comparison between solar powered LED light and conventional light is that the LED lamps have a greater lifespan and electrical efficiency that is many times better than the conventional lighting system. Beside this, LED lights are significantly much better than the most fluorescent lamps as well.


    How Does Solar Lighting Work?


    Solar LED lights are extremely efficient in the same way standard solar energy is efficient, solar LED lights are completely off-grid and incorporate battery technology.


    The world is pushing for more renewable energy to avoid the adverse effects of climate change. According to World Energy, just the average global solar radiation per year can produce just as much energy needed as 140 m3 of natural gas, 200 kg of coal, or a barrel of oil. This means, under the right optimisation process, solar energy can indeed replace modern energy sources we have today.


    If we’re to talk about the basics, it's obvious that solar LED street lights work by utilising solar energy – however, it doesn’t stop there. These street lights are actually dependent on photovoltaic cells, which are the ones responsible for absorbing solar energy during daytime. These cells eventually convert this solar energy into usable electrical energy that can power the lamps during night-time. This process repeats everyday, and potentially even be a way for the street light to have a sustainable source of energy for as long as the sun is up.

    Solar LED street lights rely on the photovoltaic process, which allows the solar cell to convert sunlight into usable electrical energy. This is done when negatively-charged electrons push solar energy into positively-charged spaces in the cells. This process allows solar energy to transfer into the electrons – becoming direct current electricity. Similar to how electricity-based gadgets work, wires from the solar cell are then connected to the battery in order to transfer the fresh direct current electricity from sunlight.

    It's when night arrives that the solar cell will stop the conversion process as sunlight disappears. Photoreceptors will help shut the solar cell down when there’s not enough sunlight to convert. This is when the battery will start supplying power to the LED lamp via other wiring.

    Solar LED street lights work in all areas, especially in areas without much access to electricity. The portable and environment-friendly nature of a solar LED street light can make them an ample replacement for ordinary street lights, and a sound option for areas with no access or limited access to an electrical grid.


    Benefits of LED Solar lights


    1. No cabling, trenching, or metering
    2. No power outages
    3. Battery backup for cloudy or rainy weather conditions
    4. Distributed light and power – no single point of failure for enhanced security
    5. Easy to install with quick connect plugs – less than 1 hour
    6. No scheduled maintenance for up to 5 years
    7. No cost of transformers or meters
    8. Qualify for savings from grants and interest free loans on technology
    9. No ongoing electric bills
    10. Controlled charging to prolong battery service life
    11. Long-life PV modules with more than 25 years of power generation capacity and 10 year warranty
    12. Environmentally-friendly – 100% powered by the sun, solar panels reduce fossil fuel consumption, eliminating pollution
    13. Self-contained solution – Light on/off controlled by automatic daylight sensing or hour preset, no running or maintenance cost
    14. Improved light source – LED lights feature cool white light without flickering and higher brightness than sodium lights
    15. Safe 12 volt/24 volt circuit, no risk of electric shock


    4 things to consider before buying LED Solar Lights


    LED light source.
    Solar street lamps generally use LED light source, and mostly use 1W high-power lamp beads, generally a lamp bead power of 1W, the number of lamp beads is the number of watts.


    Battery board.
    Solar street lamp panels are generally single crystal and polycrystal, and the price of single crystal is higher than that of polycrystal. General customers do not have professional measuring instruments, it is recommended to use size area to measure and balance, the larger the size area, the larger the size of the panel is proportional to the power of the panel.


    Accumulator battery.
    Solar street lamp batteries are generally divided into three types: lead-acid battery, colloid battery and lithium battery. At present, colloid and lithium batteries are commonly used. The cost of lithium battery is higher than that of colloid, and that of colloid is higher than that of lead acid battery.


    Lamp pole.
    Lamp pole mainly considers height and shape and parameters, the higher the lamp pole height, the corresponding parameters should be increased, the price will also increase, the more complex the shape of the lamp pole, the price will also increase.
