Can You Leave Solar Lights Out in The Winter?

There are numerous compelling reasons to consider the installation of solar-powered lights both inside and outside your residence. Solar lighting presents an eco-friendly substitute for traditional lighting as it operates entirely off-grid, drawing absolutely no energy from conventional power sources. Instead, these systems rely entirely on the sun’s abundant and renewable energy, making it a prime example of sustainable energy utilization. However, when the winter season arrives, you might find yourself pondering whether it’s suitable to keep your solar lights outdoors during this period.

Yes, you can leave your solar lights out during the winter, but this could change depending on the climate you live in, whether you live in an area that is humid, arid, dry, or wet, and how long they could go without any sun.

Solar lights are also not only maintenance-free but are also low-cost installations that guarantee zero energy bills. Solar lights also offer versatility. Because solar lights don’t require complex electrical wiring, solar lights can be installed nearly anywhere that receives direct sunlight.

How do Solar Lights Work?

Solar lights have a very simple design. Whether it’s a small garden stake light or a large commercial solar lighting system, they all employ the same technology in terms of how they operate. Below is a basic overview of how these essential lighting fixtures work.

Solar lighting fixtures consist of four major components, including a solar panel, battery, control devices, and the light fixture itself. During the day, the solar panel gathers the energy to charge the battery thanks to the photons produced by the sun’s rays. These photons stimulate the electrons in the panel’s silicon cells.

The electrons are repeatedly knocked off and collected by the wiring of the solar panel and transferred to the battery for storage. It is imperative to note that this process occurs from the time the sun rises till it sets. Also, full power generation doesn’t occur till mid-day.

Regardless, the panels can generate energy in nearly any circumstance there is sunlight. The battery charges throughout the day as sunlight continues to be converted to electricity.

During the evening, the cells in the solar panel stop converting sunlight as it gradually weakens and eventually disappears. A photoreceptor on the fixture detects when the sun’s power subsides and turns on the light. The battery then provides power to the lighting fixtures throughout the night.

This process continues day after day. During the night, the battery supplies energy to the light until the energy is either used up or the photoreceptor shuts off the light when daylight reappears.

Solar Light Maintenance Techniques

To ensure optimal performance, you’ll ensure your solar power lights are well-serviced and properly maintained. Below are a few effective tips on how to service and maintain your solar power lighting equipment.

• Routinely prune all the nearby trees and shrubs: Because your solar lighting depends on the sun’s energy for power, any tree or shrub that is likely to block the sun’s rays needs to be removed to ensure the panels get full sunlight exposure. Depending on the growth rate of any surrounding vegetation, you may need to prune them as regularly as once every month.

• Clean the panels more regularly: This is equally a very critical step toward ensuring your solar power lights remain in tip-top condition. After all, solar panels have a layer of dust or any debris that prevents easy access to sunlight and this implies that the battery won’t charge fully. An undercharged battery will not only impact the performance and effectiveness of your solar lights but will also have its lifespan significantly shortened. You should clean your solar panels at least once every month for optimal function. Of course, if you reside in a particularly dusty area, you’ll have to clean your solar panels more often.

• Routinely check the fixtures for damage: As you clean your lighting fixtures, you should also inspect them for any visible damage, such as cracked casing, or dented metal components. Depending on the extent of the damage, you may need to replace the compromised parts.

• Replace the solar batteries, if needed: While solar power batteries are highly durable, their efficiency usually deteriorates with time. If your panel features a NiCd battery, you can expect it to have a relatively shorter lifespan. If you realize that your bulbs usually go out after a shorter period than they used to previously, it’s probably time to replace your batteries. Simply put, replace the solar lighting batteries if the voltages drop below normal levels.

Can solar lights stay out in winter? And where is the best place to install outdoor solar lights during the winter season?

First and foremost, it is imperative to note that most if not all solar lights work perfectly in winter provided the panels can get adequate sunlight to power up the batteries. Simply put, solar lights are designed to function effectively year-round.

Regardless, every season brings different weather challenges which will eventually impact the performance of your solar lights. In winter, because the Northern Hemisphere tilts away from the sun, this results in somewhat fewer daylight hours. This now means that your solar light fixture will have fewer hours to harness sunlight energy to power its battery. Depending on your location, the decrease in sunlight supply may vary between one and four hours.

Avoiding shadows is particularly essential during the cold season. Generally, all experts agree that lighting solar panels will generate more power when pitched at a 45-degrees angle rather than straight up. Of course, if you realize a place doesn’t allow your panel to garner adequate solar energy, consider moving the solar light or panel to a good location with better access to direct sunlight.

How Does Location Effect Solar Lights?

As previously mentioned, solar power lights work by absorbing direct sunlight and converting it to consumable energy. It doesn’t matter whether you are experiencing hot or cold ambient temperature. So long as the sun’s rays hit the PV panels, your solar lights will always function effectively. You only need sufficient sunlight to directly hit your fixture’s solar panels for at least six hours to have the batteries fully charged.

For both functional and aesthetic reasons, good placement of your solar light fixtures is crucial. To ensure they perform at peak levels, you’ll have to ensure they are installed or placed in an area where they can access as much sunlight as possible. What’s more, you also want to ensure they are placed far away from other light sources which could potentially trick them into thinking it is not dark enough to switch on.

Pay attention to trees, roofs, or walls that could shade the panels and impact their output as well as efficiency. As a rule of thumb, in America, you should adjust the panel’s tilt angle to about 45 degrees in winter and 30 degrees in summer. What’s more, during the winter season, always remove ice or snow debris from the panel using a dry towel. Additionally, if you live in a place that accumulates several inches of snow, you’ll need to make sure you clearing that snow on the ground. If it piles up, it can build up covering the collector cells.

Wrapping up Solar Lights in the Winter

Solar lighting fixtures are not only highly affordable and eco-friendly but incredibly reliable devices that guarantee peak performance year-round. They are also available in a plethora of designs to suit your aesthetic as well as functionality needs and preference. While every season brings different challenges, solar power lighting fixtures are just as reliable in the winter season as long as to take into account certain maintenance measures. Proper maintenance will not only boost their effectiveness but will also prolong their lifespan!
