Do Solar Lights Require Light Alone or the Sun?

Sunlight is the primary power source for solar lights work, which also use it to recharge their batteries. Low light levels will only partially stop them from charging, but direct sunshine is necessary for best results. Artificial light sources like indoor or outdoor illumination often need to charge solar lights adequately.

What Amount of Direct Sunlight Does Each Location Get?

The quantity of direct sunlight varies according to the climate and season. Generally, places nearer the equator have more sunlight throughout the year, whereas those farther away may have fewer winter daylight hours. The location must be considered while estimating the solar lights’ charging capacity and general performance.

Understanding How Solar Lights Work

A solar lights work has four major components: one solar panel, an L.E.D. bulb, a photoreceptor, and one deep cycle battery. Energy is  generated and then stored, like the intensity of the light, it depends on manufacturing factors such as the lumens of the L.E.D., storage capacity of the solar energy, and the efficiency of the solar panel .

The working of a solar lights work is very simple. The solar panel generates energy during the day by the photovoltaic effect, and then the energy is stored in the battery. A photoreceptor turns on the L.E.D bulb in afternoon hours and night, powering it with the energy which is stored in the battery.

Solar lights are between us and have become the most popular alternative energy sources of lighting for our gardens and streets.  At the time when these devices do not require electricity from the grid, they can be easily installed at locations with no any extra  access to electricity, reduce costs in electricity by generating power, and even it can  reduce your carbon footprint.

Factors that Can Affect the Performance of Solar Light During Winter?

Cloudy Days

It is a common mistake that we make that solar lights aren’t able to charge during cloudy days. On the other hand there are aspects that reduce the overall performance of your panels in both cases, the solar light can still get charged by the solar panel receiving direct sunlight and while diffusing solar radiation.

While on cloudy days, the primary concern is the decreased availability of light. This can affect some types of solar panels more than others,  especially making sure that the density of the clouds in the sky. Solar lights are able to get 23.80% less power on light cloudy days and 66.75% with heavy clouds.

Snow and Solar Radiation

Reduction in the solar radiation in the snowy days also affects  the performance of your solar lights. Now also, there are three additional aspects affecting solar lights in winter: 1st one is called as snow covering the panels,  second one as the position of the sun in the sky, and third and last one the duration of the days.

Snow shall show its effect in reducing the performance of a PV system by the percentage of 15, but using solar panel cleaning tools for removing the snow and ensuring the operability of the module shall reduce those losses. You can counteract the lower height of the sun in the sky by tilting the solar module at the angle of 15º greater than the latitude of solar or verifying the specifics at your state by using a solar panel angle calculator.

Duration of the Day

As we know that you can clean snow from panels and tilt their angle, one factor that you cannot control is how long the duration of winter will be. As we know Because of the rotation of the earth and earth’s position in space, the winter season produces shorter days, which highly affect how solar light charges and performs.

How Long Does It Take for Solar Lights to Fully Charge?

For calculating  how long solar lights take to charge, you must have to understand these things such as how solar panels work, the factors affecting their power generation, and how this relates to the  capacity of the battery. In this paragraph , we will explain how all of this works.

As we know that solar panels can produce power during times with reduced sunlight, daily power output of  photovoltaic (PV) modules can be consider as its maximum generation capacity multiplied by PSH (the Peak Sun Hours). The Peak Sun Hours can vary at each state, so it is needed to consider specific values of each state .

Why Do I Need to Clean Snow From the Solar Panel?

As we know that the solar panel efficiency is improved under cold temperatures, snow, on the contrary, can be a difficult problem. Beginning from the perspective of a solar panel, snow is an object that by degree or entirely obstructs the light from these solar cells, affecting its  power generating capacity.

Snow is able to greatly reduce the performance of a PV module, that might lead you to turn on the additional lighting systems consuming grid electricity for  if the solar light does not charge in the daytime.

For avoiding the  losing hours of generation, you need to perform a solar panel cleaning to take snow off the solar light. You can get it by using one of these methods:

  • Raise the temperature: the greater option to clear snow from the solar light is using a hairdryer or some other equipment to increase temperature. This can cause the snow to fall off in a matter of seconds, ensuring power generation.
  • Water it down:  As we know that Snow can be melted by spraying water with a hose. The thing you need to consider  Before doing this, is to  make sure your solar light is rated for outdoor usage.
  • Sweep off the snow: If in a situation when the snow has not fully frozen in place, you can use a broom to easily brush it off.
  • Use an antifreeze product:  the last method is to use Antifreeze products that can melt snow in a matter of seconds, ensuring the panel keeps on generating. Furthermore , using this method you need to make sure that the product does not contain a chemical that would be able to damage the PV cells.

Tips and Recommendations for Optimizing Performance for Solar Lights

Optimizing the performance of a solar light in the winter is vital to keep your home safe and illuminated. These tips and recommendations shall be helpful for you to achieve it:

  1.  First one to Tilt the solar panel to the optimal angle during winter.
  2.  Second one is ton Avoid objects and structures from shading the panel at solar light.

  4. Try to Keep your solar light free of snow.
  5. Use opt for solar light with about 1.5 – 2 days of autonomy.

How to winter-proof your solar lights

1. Face your panels east and/or west

It is needed to make the most of the sunlight you have during the winters, by facing your panels east or west-facing panels shall be able to produce  plenty of electricity in winter.

As we know that the sun sits lower at this time, that means that facing your panels east or west will get the most electricity of the winter sky.

2. Angle Them at 60°

As we know that the best practice for facing Solar panels is 30°, you have  to reposition them at the angle of 60° during winter. Facing them this way shall make sure you get the most  of the sunshine during winter. When the winter has gone away,  then you can put them back to the default angle and settings.

3. Keep Them Away From Shadows

In  Winters  maybe new shadows may be introduced, and if possible, you have to relocate your panels. This will increase the performance of your lights more than in the shadow.

4. Keep Them Clean

During the winter, you must clean the dust and grime off from your panels as this will reduce the efficiency of your solar light and block out the limited sunlight.
