The solar lamps are an ecological and economical solution for outdoor lighting. You have installed them on the terrace, along the driveway or near your gate. But now the temperatures are falling, the days are getting shorter... and you wonder if it's still reasonable to rely on solar energy in winter. Good question.
At Lumihome, we know this topic well: yes, a solar lamp can work quite well in winter. But not just any one. And not just any way. Here's what it really takes to be sure not to be disappointed when mercury dives.
What is the operation of a solar lamp?
To understand the efficiency of solar lamps in winter, it is crucial to understand how they work. Solar lamps are equipped with photovoltaic panels that capture solar light and convert it into electricity (Read our article to learn more about how solar lamps workThis electricity is then stored in rechargeable batteries integrated into the lamp. When night falls or conditions require lighting, solar lamps activate automatically, using stored energy to produce light. It is important to note that even in winter, when the sun is reduced in exposure time, solar lamps can take advantage of ambient light to charge their batteries to operate.
Winter: a real challenge for solar lamps
Winter makes the life of solar lamps a lot more difficult, and that's quite normal.
First, there is less sunlight The sun is lower, the days are shorter, and some days it doesn't even appear. Batteries integrated into luminaires capture less energy and store less autonomy.
Then, the nights fall much earlier. A solar lamp that lights up at the dawn of the day will therefore operate longer every night...with less energy reserve.
Finally, the cold slows battery performanceAt low temperatures, lithium-ion accumulators lose efficiency. Even quality models have reduced their range.
"We all know at Lumihome: in winter, a solar lamp must be more efficient than ever. That's why we design and manufacture models only with a greater autonomy." Christophe Coelho, founder of Lumihome
What really happens when it's cold and gray?
In concrete terms, winter highlights the limits of the less efficient solar models.
- The Power reserve decrease: instead of 6 to 8 hours of autonomy, some low-end lamps will only last 2 or 3 hours.
- Light fixturesturn on at 5pmIf the battery is low, they may turn off in the evening.
- The frost, snow or dead leaves can cover the solar panel and prevent any recharge.
- L-l-l-orientation is crucial: a poorly exposed panel will not capture the little sun available.
What types of solar luminaires are well-resistant in winter?
- Models with high battery capacity, as at Lumihome : they store more and offer a higher range, even with a low daytime charge.
- Light fixtures equipped with motion detectors - they only turn on when they detect a presence, which saves the battery (Discover our solar lighting with motion sensors.)
- Models with Low-power LED : for efficient lighting while reducing energy needs.
- Lights tested for low temperatures : their electronic components are designed to withstand winter conditions.
"At Lumihome, we have equipped our models with a specific mode for winter (mode 3) which allows to extend the capacity of the Solar lamp to light up a greater part of the night."
Our tips for optimizing your solar lamps in winter
-
Always steer the panels south, with a pronounced inclination, to capture maximum light.
-
Clean regularly the surface of the panel with a soft cloth.
-
Avoid shaded areaseven though they seemed correct in summer.
- If the sky is covered several days in a row, temporarily disable the lamp to avoid total discharge of the battery.
Should we get his solar lamps in the winter?
It all depends on their quality and use.
Well-designed outdoor solar lamps — like those we offer at Lumihome — can stay out all year round. Just ensure that they are properly positioned and maintained.
However, the small purely decorative models, often less waterproof and less autonomous, can be stored until the beautiful days return. You will thus preserve their lifetime.
What to remember (and especially apply)
Solar lamps are not reserved for summer. With suitable products and minimum precautions, they can accompany you all year round – even in the middle of January.
And if you are looking for a model that is really designed for winter conditions, our team will be able to advise you on the most powerful lights of the moment.
