Solar Lights Not Working After Rain? Troubleshooting Tips!

Although outdoor solar lights are built to withstand water and rain, they can be overwhelmed, especially during heavy rains, and end up not functioning. If the solar light is filled with water, disassemble it as needed and dry off all the accessories, paying close attention to the sensor.

If you often notice solar lights work too low after rain, this article is for you! We have explored different issues associated with a solar light sensor malfunctioning during rain. 

Keep reading as we delve into the reasons why solar lights malfunction. We will also offer detailed solutions and address frequently asked questions in this discussion. 

Can Rain Damage Solar Lights?

Solar lights use enough sunlight to emit light. That is why they are ideal for outdoor use. They comprise several components like solar panels, rechargeable batteries, LED bulbs, and light sensors. 

These components work together systematically. The panels absorb sunlight, converting it to electrical energy stored in batteries. As daylight fades, motion sensors activate, powering LEDs using stored energy. 

This cycle repeats during the night. Even if the lights get exposed to elements like rain or wind, they feature weather-resistant materials to remain functional. Continuous advancement in technology today ensures reliable operation in challenging outdoor conditions.

The IP Question

Water resistance in solar lights is essential for outdoor durability. Most solar lights are given a two-digit IP (Ingress Protection) rating. 

The IP rating system indicates a light’s resistance to solids and liquids. For example, an IP65 rating ensures the light is dust-tight and can withstand low-pressure water jets. 

Solar lights with IP65 or higher ratings are well-protected against rain. They safeguard internal components from water damage. Plus, they ensure reliable performance in the rainy season. 

Now, what does 65 mean in IP65? The first digit rates protection from solids (0 to 6), while the second rates water resistance (0 to 9). For example, an IP65 solar light is dust-tight (6) and resistant to low-pressure water jets (5), ideal for outdoor use. Understanding these ratings informs users about solar light suitability for outdoor applications. 

What Are The Most Common Reasons When Outdoor Solar Lights Not Working After Rain?

Rains can adversely affect the functioning of solar lights. But how do you detect a faulty sensor or water intrusion? 

You may avoid potential issues through proper installation and regular maintenance. We have mentioned a few common reasons that affect solar lights after exposure to rain.

Water Damage to Electrical Components

Water infiltration into the internal components can cause short circuits. This damage can lead to the lights failing to function correctly. You need water-resistant wiring insulation during harsh weather to prevent water inside your electrical items.

Moisture in the Solar Panel 

Moisture within the solar panel can impact its ability to convert sunlight into electrical energy effectively. It will reduce the brightness of solar lights. 

Corrosion of Contacts and Wiring 

Exposure to moisture can accelerate the corrosion of electrical contacts. It can also affect the wiring within the solar lights. It can disrupt the flow of electricity.

Improper Installation 

Incorrect installation, such as inadequate sealing, can leave solar lights vulnerable to water damage. It can decrease their resilience to adverse weather conditions.

Troubleshooting Tips To Fix Solar Lights After Rain

Water-related issues can often plague solar lights. They become more severe after getting exposed to rain or moisture. 

We’ll outline step-by-step instructions for diagnosing and fixing common water-related problems. These steps will cover techniques and leave solar lights outside gleaming all night.

1. Removing Water-Damaged Components

Most solar lights work on rainy days if you immediately make your solar components dry. If you feel the water has damaged the light, disconnect them from their power source. Try to remove any batteries or electrical components. 

Thoroughly dry out each component using a clean, dry cloth or towel. You must ensure no moisture remains inside the housing or around electrical connections. 

2. Inspecting for Water Damage

Carefully examine the interior of the solar lights for signs of water damage. Check if there is any rust, corrosion, or water residue. Pay close attention to battery compartments, circuit boards, and wiring. You may have to replace the light if the solar light sensor is faulty. 

3. Cleaning Corroded Contacts 

If you notice corrosion on electrical contacts or terminals, use a small brush or cloth to scrub away the corrosion gently. You can apply a small amount of electrical contact cleaner to dissolve stubborn corrosion. It will ensure good electrical conductivity.

4. Allowing Components to Air Dry

After cleaning, let all components air dry thoroughly before reassembling the solar lights. Make sure you leave no moisture inside the housing or around electrical connections. If you do, this can lead to further corrosion and damage.

5. Reassembling and Testing 

Now, reassemble the solar lights. You must ensure that all components are securely in place. Insert fully charged batteries and reconnect the lights to their power source. Test the functionality of the solar lights to ensure that they are operating well. 

6. Implementing Preventive Measures

Consider implementing preventive measures to protect your solar lights from future water damage. Regularly inspect and maintain your solar lights to prevent water-related issues.

Can Solar Lights Get Wet? Preventative Measures to Protect Outdoor Solar Lights in Rain 

Protecting outdoor solar lights from rain is critical to ensure longevity and performance. Implement preventative measures to help safeguard solar lights against water damage. Let us explore a few strategies for preventing water damage to outdoor solar lights.

Proper Installation and Placement

Installation and placement can help minimize exposure to rainwater runoff. It will reduce the risk of water pooling around the lights. We also suggest you buy solar lights with the latest technology. 

Regular Maintenance and Care

Cleaning solar panels and light fixtures can help remove dirt and moisture. Tightening loose connections and replacing worn-out components can prevent water-related issues from escalating.

Weatherproofing and Protective Measures

Apply waterproof sealant around seams, joints, and electrical connections. They can help prevent water intrusion. 

You can install protective covers over solar panels. They can provide additional protection against rain. Choose solar lights with higher IP ratings to ensure greater resistance to water.

Is It Time to Replace Your Solar Lights?

Knowing when to replace your solar lights is essential to maintain optimal illumination. Several signs indicate that it’s time to replace solar lights rather than attempting further repairs:

Diminished Light Output

If your solar lights are dimmer than when they were first installed, it may indicate that the batteries are reaching the end of their lifespan. Diminished light output can also result from degraded solar panels or damaged circuitry. So it may be difficult or costly to repair.

Corrosion and Physical Damage

Extensive corrosion, rust, or physical damage may compromise the function of the solar lights. So repairing may not help any severely damaged parts. In such cases, it’s better to replace the solar lights. 

Frequent Malfunctions

If your solar lights experience frequent malfunctions despite repeated repairs, it may indicate that it’s time to replace them. Troubleshooting and repairing malfunctioning solar lights can take time and may not guarantee long-term reliability.

Outdated Technology

As solar lighting technology advances, older models may become less efficient compared to newer ones. So you need to upgrade to newer solar lights with improved features. It’s a wise investment and saves you a lot of cost in the long run than dealing with outdated models.

End of Lifespan

Most solar lights have a finite lifespan. Depending on usage and environmental conditions, they range from 3 to 5 years.

If your solar lights have reached the end of their expected lifespan, replacing them with new units will be an intelligent decision.
