• When to Adjust the Working Mode of Your Solar Lights for Winter Operation?

  Dec 03, 2025

  Adjusting the working mode of your solar lights for winter is critical to address reduced sunlight (lower battery charging) and longer nights (higher energy demand)—two core challenges that can leave lights dim, short-lived, or non-functional if unaddressed. The key is to prioritize battery preservation without sacrificing essential illumination. Below is a clear guide on when to make adjustments, what to adjust, and why it matters.   When to Start Adjusting: Key Triggers for Winter Mode Begin modifying your solar lights’ settings 1–2 weeks before the onset of consistent winter conditions (e.g., shorter days, frequent cloud cover, temperatures below 10°C/50°F). Use these cues to act:   Daylight Hours Drop Below 9–10 Hours   Winter solstice (Dec 21 in Northern Hemisphere, Jun 21 in Southern Hemisphere) brings the shortest days (often 8 hours or less of usable sunlight). Even before the solstice, when daily sunlight falls below 9–10 hours, solar panels struggle to fully charge batteries. This is the most important trigger—act when you notice your lights dimming by midnight or turning off early. Consistent Cloud Cover or Rain/Snow   Overcast skies reduce solar panel efficiency by 30–60%. If your region experiences 3+ consecutive days of clouds, snow, or rain, adjust settings immediately to avoid draining the battery completely (deep discharge can damage batteries long-term). Temperatures Stay Below 10°C (50°F)   Cold temperatures slow battery chemistry (lithium-ion and NiMH batteries lose 10–30% of their capacity in freezing weather). Even with adequate sunlight, a cold battery stores less energy—so you’ll need to reduce power usage to extend runtime.   Lights Fail to Stay On Through Critical Hours   If your solar lights (e.g., security lights, path lights) turn off before dawn or dim drastically by 2–3 AM, it’s a clear sign the battery isn’t holding enough charge for winter’s longer nights. Adjustments are necessary to align energy use with reduced charging. New Installation in Late Fall   If you install solar lights in October/November (Northern Hemisphere) or April/May (Southern Hemisphere), set them to winter mode immediately—don’t wait for performance issues. This prevents premature battery depletion as days shorten.   What to Adjust: Winter-Friendly Settings Most solar lights (path lights, security lights, floodlights) have adjustable modes via a switch, remote, or app. Focus on these settings to optimize winter performance: 1. Brightness Level (Priority #1) Winter Adjustment: Lower from "High" to "Medium" or "Low."   Example: A 1000-lumen security light on "Medium" (500 lumens) uses half the energy, doubling runtime. Path lights can switch from "Steady On" to "Dim Steady + Bright Motion" (if available). Why: Brightness directly correlates to energy use—reducing it is the easiest way to preserve battery life without eliminating light entirely. 2. Motion Sensor Duration (For Security Lights) Winter Adjustment: Shorten the "on time" after motion is detected (e.g., from 5 minutes to 1–2 minutes). Why: Security lights often stay on longer than needed. Cutting the duration reduces energy waste, especially if motion is frequent (e.g., pets, passersby). 3. Motion Sensor Sensitivity (For Security Lights) Winter Adjustment: Lower sensitivity (if adjustable) or narrow the detection range. Why: Cold weather can trigger false alarms (e.g., wind-blown debris, frost melting), and lower sensitivity reduces unnecessary activation—saving battery. Avoid disabling motion sensing entirely (unless you need constant low light). 4. Working Mode (Steady vs. Motion-Activated) Winter Adjustment: Switch from "Steady On" to "Motion-Activated" (for path/security lights) or "Dusk-to-Dawn Dim + Motion Bright" (hybrid mode). Why: Steady-on mode drains batteries quickly in winter. Motion-activated modes only use high power when needed, while hybrid modes provide low-level ambient light without depleting the battery. 5. Battery Optimization (If Applicable) For removable batteries: Ensure they’re fully charged before winter (replace old batteries >2 years old, as capacity degrades over time). For integrated batteries: Avoid deep discharge (don’t let lights die completely)—adjust settings to keep a partial charge.   When to Revert to Summer Mode Switch back to your solar lights’ original settings 1–2 weeks after spring equinox (Mar 20 in Northern Hemisphere, Sep 22 in Southern Hemisphere) or when:   Daylight hours exceed 11–12 hours consistently. Temperatures rise above 15°C (59°F) and cloud cover is minimal. Your lights hold a full charge and stay on through the night without dimming. Key Winter Pro Tip for Solar Lights Even with adjusted settings, clean your solar panels monthly in winter. Snow, ice, dust, or debris blocks sunlight—reducing charging efficiency by up to 80%. Wipe panels with a soft cloth (avoid sharp tools) to maximize energy intake.

• LiFePO4 vs. Lead-Acid: Why Battery Chemistry Matters for Solar Lights

  Nov 20, 2025

  The chemical properties of LiFePO4 (lithium iron phosphate) and lead-acid batteries determine their significant differences in lifespan, energy efficiency, installation difficulty, and maintenance demands. These differences directly affect the operational stability, long-term costs, and applicability of solar lights. For solar lighting systems that rely on intermittent solar energy storage and need long-term outdoor operation, the choice of battery chemistry is crucial.   Cycle Life and Long-Term Reliability LiFePO4 batteries: Their chemical structure is stable, enabling them to undergo 3000 - 5000 charge - discharge cycles. Even with deep discharge, they can maintain a long service life of 8 - 15 years. For solar lights that need daily charging and discharging, this means they can operate stably for a long time without frequent replacement. Moreover, the built-in Battery Management System (BMS) can prevent overcharge, over-discharge and other issues that damage the battery, further extending its service life.     Lead-acid batteries: Their chemical reaction mechanism leads to a much shorter cycle life, usually only 300 - 1000 charge - discharge cycles. They can only last 2 - 4 years in solar light applications. After multiple cycles, the lead - based electrode materials are prone to aging and sulfation, which rapidly reduces battery capacity. Solar lights using lead-acid batteries need frequent battery replacement, which not only increases the workload but also may cause the lights to be out of service during the replacement period.   Energy Conversion Efficiency LiFePO4 batteries: The electrochemical reaction during charging and discharging is efficient, with a conversion efficiency of over 90%, and some high-quality products can even reach 95 - 98%. This means that most of the solar energy collected by solar panels can be stored and converted into electrical energy for lighting. It only takes 2 - 4 hours to fully charge, allowing the battery to quickly store energy even on days with short sunny hours, ensuring the solar lights have sufficient power at night.     Lead-acid batteries: Their charge-discharge efficiency is only 70 - 80%. The internal resistance of the battery is relatively large, and a lot of energy is lost in the form of heat during charging and discharging. In addition, they need 6 - 12 hours to be fully charged. In areas with insufficient sunlight, they may not be fully charged, resulting in insufficient lighting time for solar lights at night, which seriously affects the user experience.   Installation and Structural Adaptability LiFePO4 batteries: They have high energy density and are lightweight. A 100Ah LiFePO4 battery only weighs 11 - 15kg. This feature makes the installation of solar lights very convenient. There is no need for heavy lifting equipment, and a small number of workers can complete the installation. Meanwhile, its compact size allows flexible installation methods such as vertical or horizontal placement, which can be well-matched with integrated solar street lights and other compact solar lighting products without putting too much structural pressure on the light pole. Lead-acid batteries: They are bulky and heavy. A 100Ah lead-acid battery weighs 25 - 30kg. When installing solar lights, it requires more labor or even lifting tools. Moreover, due to their heavy weight, higher requirements are imposed on the load-bearing capacity of the light pole and the installation foundation. For some lightweight solar light brackets or complex terrain installation scenarios such as mountain trails, the use of lead-acid batteries is very restrictive.     Environmental Adaptability and Safety LiFePO4 batteries: They have excellent thermal stability and can work normally in the temperature range of -20°C to 60°C, with a capacity loss of less than 15%. They are not prone to fire or explosion even in extreme weather such as high temperatures. In addition, the materials of LiFePO4 batteries are non-toxic and pollution-free, which is in line with environmental protection requirements. Lead-acid batteries: Their performance is greatly affected by temperature. When the temperature is lower than 0°C, their capacity will be reduced by 30 - 50%. At high temperatures above 40°C, there is a risk of thermal runaway.   Moreover, lead-acid batteries contain lead and sulfuric acid electrolyte. If they are damaged, the electrolyte will leak and cause soil and water pollution. At the same time, lead is a toxic heavy metal, which will also cause harm to the environment and human health during production and recycling.     Maintenance and Long-Term Cost LiFePO4 batteries: They are maintenance-free. There is no need to add electrolyte or perform other regular maintenance operations during use. Although their initial purchase cost is high, the long service life and low replacement frequency mean that the long-term cost per cycle is only 1/3 of that of lead-acid batteries. For large-scale solar lighting projects, it can save a lot of replacement and maintenance costs. Lead-acid batteries: They require regular maintenance. The electrolyte will volatilize during use, and it is necessary to regularly check and supplement the electrolyte to avoid battery failure. Their low initial cost is offset by frequent replacement and maintenance costs.   For example, a lead-acid battery for solar lights needs to be replaced every 2 - 3 years, and the cumulative replacement cost over 10 years is much higher than the cost of a LiFePO4 battery.

• What is the reason for the battery failure of solar street lights

  Aug 02, 2023

  Solar street lamps are outdoor lighting devices that utilize solar power supply. If the battery of solar street lights malfunctions, there may be several reasons: 1. Battery aging: The battery life of solar street lamps is limited, and after prolonged use, the battery may gradually age. Aging batteries will reduce their capacity and cannot store enough energy to supply streetlights. This may result in the street lights not working properly or their working hours becoming shorter. 2. Charger failure: The battery of the solar street lamp is charged from the solar panel through the charger. If the charger malfunctions, it may not be possible to convert solar energy into electrical energy and store it in the battery, resulting in the battery not being able to charge properly. 3. Solar panel issue: The solar street lamp panel is responsible for converting solar energy into electrical energy to charge the battery. If the battery panel is damaged, dirty, or obstructed, it may not be able to effectively absorb solar energy, resulting in the battery not being able to obtain sufficient charging capacity. 4. Over discharge or overcharging: If the charging control system of solar street lights malfunctions, it may cause the battery to be over discharged or overcharged. Excessive discharge can damage the battery and prevent it from working properly. Overcharging may lead to a decrease in battery life. 5. Environmental factors: Solar street lamps are often exposed to outdoor environments and are influenced by factors such as climate, humidity, and temperature. Extreme environmental conditions may have adverse effects on batteries, such as in extremely cold winter or hot summer, where battery performance may decrease. If the battery of the solar street lamp is found to be malfunctioning, it is recommended to contact professional solar street lamp maintenance personnel for inspection and repair. They can help identify specific issues and take corresponding repair measures. Hello!

• Reasons for solar panels not generating electricity in solar photovoltaic systems

  Aug 04, 2023

  The cross-section of a solar panel consists of five layers: photovoltaic glass, EVA, solar cells, EVA, and backplane. Reasons for solar panels not generating electricity in solar photovoltaic systems If the customer asks if the solar panel does not generate electricity, if the customer has purchased a controller, first ask the customer to provide a photo of the controller and see where the indicator light of the controller is not on. If the solar panel indicator light is not on, it may be: 1、 If the customer has a multimeter, they should first test it to see if it is a problem with the solar panel itself. It is rare for the quality of the solar panel itself to be very poor, and it is generally due to improper use. 2、 The customer's MC4 connector was not properly connected and the wire was not properly clamped, causing it to become loose. The customer can check if it is a wiring issue. 3、 Ask the customer if there is sunlight or obstruction at the installation site. If there is obstruction or absence of sunlight, it can also affect power generation. 4、 Ask the customer what the voltage of the battery is. Some customers may purchase an 18V solar panel to charge a 24V battery, which is definitely not enough. If this is the case, we can guide the customer to purchase another solar battery of the same specification in series 5、 Another possibility is that the diode has burned out. Customers can open the solar panel junction box and then open it to see if there are any signs of burning out of the diode 2. Is the current of the solar panel low or low? The main causes of low current in solar panels The customer has issues with the usage environment, the environment is obstructed, or the angle is incorrect. There were issues during the customer's testing period, and the best time to test and replace parts is between 12:00 noon and 14:00 pm. The current measured facing south is the highest. The same as before, the diode burned out, which may be caused by the customer's reverse polarity. 3. Controller issues. 1、 The 150 151 controllers we make ourselves all have light timing, and the load does not work or does not charge, 90% of which is caused by customers accidentally pressing the dimming timing switch. Please refer to the manual for details and ask the customer to switch back to the general mode 2、 Many customers ask us not to charge, and there are basically many things that we haven't connected to the battery. They tell them that the controller is also a load that needs to be connected to the battery to work. 3、 The wire is not properly connected or the connector is loose. Customers can check if there are any issues with the wiring. 4、 The voltage of the photovoltaic battery does not match, and some may buy a 200W 12V battery. If the voltage does not match, the battery cannot be charged. Hello! Feel free to contact us if you have any questions during use, and we will provide you with satisfactory solutions as soon as possible! I hope to bring you better products and services.
