Solar Lights in Winter

Here is your ultimate guide. Do solar lights work in winter? All the sub-queries triggered by this main question will be addressed in this guide for a solar street lighting system. Are you ready? Let’s proceed!

Question #1: Can solar lights work in winter?

The answer is yes–so long as the solar panels are storing an amount of sunlight adequate to charge and initialize the batteries. If that’s the case, your solar street lights will definitely work given that there are no occurrent problems detected. Solar lights, granted that they receive the right value of sunlight, will always perform well as they are designed that way.

Question #2: Do I need rechargeable batteries for my solar lights?

Definitely. Solar street lights work using rechargeable batteries that get powered up as the solar panels receive light from the sun. Your solar lamps should shed illumination once the sun has set and the darkness came peeping in.

Question #3: How can I charge my solar lights in winter?

Bear in mind that the batteries do charge in the same way at any season of the year. It’s just that, the sun appears at a longer period during the summer solstice, and at a shorter period during the winter solstice. The best thing to do is to find the perfect spot for your solar lights, install them where the sun can light them up for at least or more than 8 hours a day.

Question #4: How can I charge my solar lights without the sun?

In the same way, your solar panels do their work and perform their tasks even on a cloudy day. How do your solar lights charge without the sun? They also absorb the energy from daylight, not only from the direct sunlight. However, dark clouds will really reduce the output of your solar street lights and solar panels. The sun’s rays would need to pass through thick components of the atmosphere; thus, the clouds will absorb more daylight.

In this situation, you can store your solar lamps inside for a while.

Question #5: Why are my solar lights not working at night?

If your solar street lights are not functioning, you can try to carry out some troubleshooting steps to identify the problem of your solar units and have them resolved.

  • Check if the power is activated
  • When testing at daytime, try to simulate darkness to see if it will work.
  • Remove the battery’s pull tab (if there is).
  • Reposition the solar panels.
  • Replace the batteries, they might have been overused, which resulted in dysfunction.
  • Maintain the cleanliness of the solar panels.
  • Go for the ‘deep charge’ technique. Expose the solar panels to the sun’s heat for at least 72 hours without using them at night. See if this makes a difference.
  • Ask for the help of a professional.
  • Contact the supplier or manufacturer of solar street lamps.

Question #6: Can solar lights work in the shade?

Yes, of course. The solar lights can still absorb energy from the daylight scattered in the environment, so they will still function. However, if you are looking to achieve the lights’ best and maximum performance, you should avoid shades, place them where they can get direct sunlight, and tilt the solar panels at an angle that faces the direction of the sun.

Question #7: What are the best solar street lights for winter?

You can check out the different manufacturers around your area, set an appointment with them, and have them discuss the features of their solar street lights. Many solar lights can be really great for winter but have a poor performance for certain applications. So, you need to ask yourself first, what is the purpose of using solar street lights? What is the application?

Upon identifying the application, you can narrow down your options already. Bluesmart’s various solar street lighting products include the following types: fly hawk, swan, moonlight, and fly egret series. You can also ask for their assistance in helping you select the right solar lamps for your application which are best for the winter.

But the good news is, we can still figure out some ways to troubleshoot or turn the disadvantages into practical solutions. As a client or buyer of solar street lights, you should not fear that you will not get the best out of your solar lamps. If you are to compare the positive features of the product with its weaknesses, it still gives you a win-win situation!

The solar-powered street lighting system is eco-friendly; it reduces carbon footprints. It upholds renewable energy and cost-efficiency. It produces zero greenhouse gas emissions, and it does not stimulate any hazards. And yes, solar lamps can still operate during the winter.
