# What Does W And C Mean On Solar Lights? (answered)

Here’s What Does W And C Mean On Solar Lights? c=When dark, until motion is detected, turn off the lights, then strong light for 15 sec. F. Solar lights can be turned off when not in use because they have an on/off switch. Instead, you can activate the switch whenever you want your light to be on. Typically, they have an inbuilt sensor that controls when the lights charge and turn on.

## What Does W And C Mean On Solar Lights?

Before we get started, we must grasp the fundamental differences between solar and LED lighting. Solar energy is the battery power supply that needs to be charged, whereas LED lighting is the grid’s direct power supply (i.e., the voltage we use to connect home appliances).

Therefore, they cannot be entirely perplexed. I won’t go into depth about KW/H power because I think you are already familiar with it. I’ll now explain how to estimate the battery’s energy. W stands for tile, h for hour, and W is the energy unit.

The physical definition of battery capacity, according to popular usage, is how much charge the battery can keep or release. We frequently express it in terms of Ah (ampere time) or mAh (milliampere time).

We know that Q = It, mA (milliampere) in unit time of current I, T indicates time, unit hour (time). Thus our battery capacity unit is mAh. The definition of current is: I = Q / t. In other words, if a battery has a 1000 mAh capacity and a working current of 100 mA, the power source might theoretically be used for 10 hours.

But since the voltage is not a factor in the formula for Q, this unit can only represent the number of coulombs of charge that a battery can store. However, it is unable to specify how much work or how much power this battery is capable of producing at once.

Different types of items have varying working voltages. So, next to mAh, we frequently see a figure in Wh. The W in the battery is expressed in Wh, representing how much work the battery can do because the work W = UIt = UQ, and the unit of the voltage U* current I is W (watt).

The voltage of the previously indicated 6600 mAh battery is 14.4V, translating to a total work capacity of 6.6 * 14.4 * 3600 = 342144 joules. 14.4 * 6600 = 95.04 Wh.

The quantity Wh is inversely proportional to voltage, current, and time. MAh is frequently used as a measure of battery charge and discharge. It varies inversely with the battery’s charge (discharge) current and time. Knowing the battery voltage is important to convert it to a unit comparable to Wh. Wh is defined as mAh/1000 x voltage.

## What To Do If Your Solar Lights Don’t Work?

You must examine each component of your solar lights to determine which one has broken. Each light’s solar panel needs to be cleaned first since a layer of dirt might accumulate there and block the sunlight from passing through. Keep in mind to place your lights where they will receive the most sunshine, and if your solar lights are tiltable, make sure they are pointed in the direction of the sun.

It’s a good idea to look inside the battery compartment for any damage indications, such as rust, water damage, or frayed wires. Additionally, make sure the batteries are securely attached and look for corrosion.

A circuit board or charge controller simultaneously serves as a sensor or switch inside every solar lamp. The circuit board transfers the charge from the solar panel to the battery when the sun shines.

When it gets dark, the circuit board or sensor detects no light coming from the panel and stops the battery from being charged rather than using the battery to power the LED bulb. Once the backyard solar light has been cleaned, dried, and given time to recharge, they frequently begin to function once more.

Checking the LED or bulb is the next step if your light is still not functioning. Placing a regular non-rechargeable battery inside a solar light LED with AA or AAA installed is an easy way to test the light.

If the LED or bulb is functioning properly, completely cover the panel or place it in a room with no light. Unfortunately, it’s probably time to discard the light if the LED doesn’t function any further. Lastly, try changing the batteries in the solar lights.

## Why Do My Solar Light Batteries Need To Be Changed?

The rechargeable batteries within outdoor solar lights typically quit functioning because they are worn out. Your solar lights must use rechargeable batteries since the solar panel transforms sunshine into electricity to fuel the batteries, which power the light. Not everyone is aware that rechargeable solar light batteries exist.

Changing the batteries in your solar lights regularly, maybe once or twice a year is a good idea. Rechargeable batteries with limited capacity are used in almost all outdoor solar lights. Recently, 1.2V NiMH (Nickel Metal Hydride) batteries have been used in solar lamps. The more recent NiMH batteries have replaced the older NiCd ones.

## What Kind Of Batteries Should I Put In My Solar Garden Lights?

Solar lights employ rechargeable 1.2V NiCd and NiMH batteries, which come in various sizes and capacities. The most common size is AA, which measures 14.5mm in diameter and 50.5mm in height. Another common size is full-size AAA, slimmer than AA at 44.5mm high and 10.5mm in diameter.

Other, less common and more difficult-to-locate sizes include 2/3AA rechargeable batteries, which measure 31mm x 14.5mm and are two-thirds the size of a full AA. Rechargeable 2/3AAA batteries are 30mm long and 10.5mm in diameter, two-thirds the size of a AAA battery.

## What Are The Best Battery Alternatives For My Solar Garden Lights?

The batteries you remove from the solar lights must be replaced with ones of a similar voltage and capacity. For instance, we would advise replacing the 1.2V 600mAh AA NiCd or NiMH batteries in your solar lights with our 1.2V NIMH AA 600mAh solar light batteries. Your old batteries’ capacity is typically listed in the mAh rating.

As long as the battery is the same voltage, you can replace it with one that has a little different mAh capacity, although we advise selecting replacement batteries with the closest mAh rating you can. Replace your batteries with ones with a significantly higher mAh capacity if possible.

## Final Verdict

Did you get What Does W And C Mean On Solar Lights? Solar lights don’t require much maintenance, but they require regular clean solar panels. Every so often or whenever you see that the solar panels on your solar lights are becoming dirty, wash them with soap and water. Since any dirtiness won’t obstruct the sunlight, this will guarantee they function to their fullest capacity.

### Should I power my solar lights with high-capacity batteries?

It is simple to assume that the more capacity, the better the solar lights will function. This is not true. Recharging high-capacity rechargeable batteries typically require a higher current. It is preferable to utilize solar light batteries with a modest capacity because solar light produces such a low charge current.

### Why do my solar-powered lights turn on in the daytime?

This indicates that the light sensor isn’t functioning. The small solar panel should be cleaned because dirt commonly accumulates on them. The solar light circuit board will behave as if it is always dark or nighttime if the panel is dusty, which will cause the battery to supply power to the LED both during the day and at night. Fresh batteries cannot bring on this problem because they power the LED. If your lights remain on constantly, the batteries are in good condition.

### Can I power my solar lights with regular, non-rechargeable batteries?

The LED in the solar lights can be tested to see if it operates as previously specified using a standard non-rechargeable battery. In this case, you shouldn’t use non-rechargeable batteries in a garden solar light that can be recharged.

### Are solar lights’ plastic covers removed?

The most expensive component of solar light is typically the solar cell itself. The cost of photovoltaic technology is gradually declining as it develops. Be aware that certain panels are provided with a removable protective plastic covering. It must be taken out for the panel to charge correctly.
