How Solar Flood Light Works

Solar flood lights work by utilizing several electronic parts to capture solar energy to produce electrical energy.

Once they convert the solar energy to electrical energy, it stores them in batteries.

Solar panels will harness the solar light energy within the solar cells which converts it to electricity that the light operates on.

The batteries will enable the solar flood light to operate throughout the night.

Photosensors are components that determine whether is daytime or nighttime.

Besides, they assist in turning on the solar flood light at nighttime only.

Once the photosensor triggers, the LED will emit light once the batteries release electricity.

Factors Affecting The Cost Of Solar Flood Light

Besides, solar energy is free and renewable hence saving you money and is also environmentally friendly.

Easy And Flexible Installation

Solar flood lights are easy to install since they have fewer parts that need connecting.

Besides, when you need to reinstall the lights, you can perform the task easily since they do not connect to the main electricity grid.

Also, you can install them anywhere as long as the solar panels directly face the sun.

How To Determine Brightness Of Solar Flood Light

The brightness of solar flood lights depends on the lumen value.

Lumen is how you measure the light output of solar flood lights and indicates their brightness.

Besides, when determining the brightness of solar flood lights, take into consideration the lumen value and not the wattage.

For instance, a 10W fluorescent solar flood light is less bright than a 10W LED solar flood light.

The average lumen rating for solar flood lights sits between 300 and 800.

How To Calculate Wattage For Solar Flood Light

Watts is how you will measure the work that electricity performs per second.

For instance, 100W of energy can light a 100W bulb for an hour.

How To Test Solar Flood Light

Some techniques you can use to test solar flood lights include:

Wall mount solar flood light

 Wall mount solar flood light

Electrical Performance Test

This test involves applying electrical current to the solar flood light.

Afterward, you will measure the actual versus the expected reading.

Besides, the electrical performance test ensures the output is suitable for the solar flood light.

Color Parameter Test

This test measures the ability of solar flood lights to produce the correct color as per the specifications.

Photometric Parameter Test

In this test, you will measure the visible light and how people will distinguish the brightness of solar flood lights.

It is measured in lumens [lm].

How Long Solar Flood Light Takes To Charge

Solar flood lights may take between 6 hours and 8 hours of direct sunlight to achieve a full charge.

However, the charge time increases during winter seasons or in indirect sunlight.

Factors Determining The Service Lifespan Of Solar Flood Light

These factors entail the following:


The lighting time of solar flood lights relies on the duration and intensity of the sun as it affects the energy the solar panels absorb.

When solar panels absorb more power, they convert more electricity ensuring ample lighting.

Material Component

Using core components of low quality will affect the lifespan of solar flood lights.

For this reason, low-quality components mean the solar flood light will require regular servicing.

Operating Environment

The working environment will impact the lifespan of solar flood lights, especially when using them outdoors.

Such environmental factors include dust, humidity, temperature, etc.

This is because the batteries of solar flood lights are sensitive to environmental temperatures.

When To Replace Batteries In Solar Flood Light

Replace the batteries in solar flood lights every one to two years as they tend to lose their capacity to hold an electrical charge.

Choosing Best Solar Panel For Solar Flood Light

Solar flood lights can use one of the three solar panels available.

Examples of these solar panels include the following:

Monocrystalline Solar Panels

These solar panels are the most efficient as their efficacy ranges between 15% and 21%.

Besides, they are costly than the other types of solar panels and are suitable for high-performance solar flood lights.

Also, you can use monocrystalline solar panels in commercial buildings and large premises.

Polycrystalline Solar Panels

These solar panels have an efficacy rate of around 16% and cost less to manufacture.

Polycrystalline solar panels have dark blue hues hence easy to set them apart from other types of solar panels in the market.

Besides, they can provide enough energy to power large solar flood lights for large buildings.

Amorphous Solar Panels

This type of solar panel has a low cell efficacy ranging between 7% and 10%.

Amorphous solar panels are also popular with electronic devices and solar flood lights whose power consumption is low.

Types Of Batteries To Use In Solar Flood Light

Solar flood lights have replaceable batteries hence can function for long durations.

Examples of the batteries you can use in solar flood lights entail the following:

Nickel Cadmium [NiCd]

This is the oldest and cheapest battery you can find.

Besides, they can function in very hot and cold environmental conditions ranging between -30°C to +50°C.

However, nickel-cadmium batteries suffer memory effects making them underutilize their cell capacity.

Besides, you can charge or recondition them properly to solve this issue, however, this is not practical for solar flood lights.

Nickel Metal Hydride [NiMH]

These batteries give more longevity of up to 40% above that of nickel-cadmium.

However, nickel-metal hydrides do not function efficiently in adverse temperature conditions.

Besides, they are not susceptible to memory effects but their run time will decrease over time.

Lithium-Ion [Li-Ion]

These batteries hold more power in small packages making them suitable for solar flood lights.

Besides, they are not susceptible to memory effects but are very volatile.

Their volatility is due to the lithium salts and non-dense metallic parts within them.

What C, F, And S On Solar Flood Light Mean

S is for static, F is for flashing, while C is for continuous mode.

Limitations Of Solar Flood Light

They include the following:

  • They will not charge at night
  • Highly efficient solar panels cost more
  • Also, you need large batteries for large applications
  • You need to frequently clean the solar panels to make them effective

How To Switch Solar Flood Lights ON/OFF

Not all solar flood lights come with an ON/OFF switch.

Those without the switch will automatically turn on in the absence of sunlight and on when the sun rises.

For those with the ON/OFF switch, ensure it remains ON so that it charges during the day and emits light at night.

How Long Solar Flood Light Stays On At Night

On a full charge, the solar flood lights will remain on for up to 8 hours.

Accessories You Need For Mounting Of Solar Flood Light

These include:

  • Mounting brackets
  • Screws
  • Bolts
  • Fasteners
  • Nuts

Causes Of Failure Of Solar Flood Light

Here are some reasons why the solar flood light may fail to operate:

  • Solar panels are not receiving enough direct sunlight hence fail to charge
  • The lifespan of the batteries have expired
  • Sensors within the solar flood lights are faulty
  • Dirt covers the solar panels hence they cannot charge
  • Water may buildup on the solar panels and damage the wiring and circuitry
  • The presence of other light sources close at by at night that interferes with photovoltaic cells that detect light

Quality Certifications And Standards For Solar Flood Light
