How Can You Slow The Degradation Of Your Solar Panels
Weve listed many of the ways that solar panels degrade above.
However, theres one large way that you can slow degradation in your solar panels, and it starts before theyre even installed.
DONT CUT CORNERS.
Too many people want to install solar panels on their residential homes, but they try to do so with low-quality products and labor.
Doing this will lead to faster degradation.
Instead, find a reputable solar installer and spend money upfront on a higher quality product.
Additionally, once youve installed your high-quality solar panels, make sure you maintain them according to the manufacturers instructions.
Although solar panels dont typically need too much care, a little bit of maintenance can go a long way!
Be sure to remove debris that may get caught in them and keep your panels clean.
Can You Charge Solar Light Through The Window
If the window is made up of a transparent, thin material then the efficiency of charging is not much different from the charging by using direct sunlight.
But if your window is thick the efficiency will be less as the window absorbs a portion of the sunlight received throughout the day. If the window is made up of dark, tinted, or opaque material then the solar light efficiency will be very low or they might not even charge as the lights do not receive any sunlight through the window.
How Much Does Cloud Cover Reduce Solar Power
Its evident that on a sunny day, solar panels operate at a higher output than on a cloudy or rainy day, but how much?
When the weather changes, there is a change in how much electric energy is generated by solar panels, simply because all of the suns energy cant reach the panel surface.
Lets find out how a cloudy day affects solar cell efficiency and output.

Cloudy Weather Vs Electricity Charge
Compared to bright, sunny weather, solar panels produce about get energy independence than to pay high electricity bills to power their homes. Its not difficult to see solar system owners making a profit on their investment regardless of the weather.
The following are the five most cloudy cities in the U.S. as of 2022:
It is no surprise that the Pacific Northwest has the most cloudy cities. Even cities in California the top solar state, like San Francisco, have lingering fog most of the year. Despite the fog, the city has a warm climate and soft sunlight throughout the year. It is a great spot for solar.
How Do Solar Cells Work
Solar lights use photovoltaic cells, which are able to convert sunlight directly into electricity. Solar panels are made up of groups of cells connected together and placed in a frame.
The cells themselves are made with special materials known as semiconductors. Silicon is the most common material used for this purpose.
When light hits a cell, some of this energy from the sun is absorbed into the semiconductor. The energy knocks electrons loose from their atoms.
An electric field forces these electrons to flow in a certain direction. This flow of electrons is an electrical current, and this current will flow through metal. In solar lights, a diode prevents this energy from flowing back out of the battery.

The Basics Of Solar Cells
The photovoltaic cells and amorphous cells used in solar panels can turn solar radiation into electricity. These cells are only able to effectively convert specific types of visible light into electrical energy. For example, infrared and ultraviolet light dont contribute much to power production.
The most efficient form of visible light for power production is within the spectrum of violet to red, or the wavelengths of 380nm to 750nm . You can either harvest this light naturally , or artificially .
Solar Lights During Winter
Sunlight exposure is limited during winter, and solar lights will also not be at total capacity in charging during the day. Additionally, accumulated snow on the panels would not allow electricity generation. You can ensure to mount panels facing the sun and in sloping orientation to shed snow during winter.
Nevertheless, solar lights can still be safely left outside during winter, and the strong winds can aid in blowing accumulated snow into the panels.

How To Fully Charge Solar Lights
The first tip is to place the solar light near a window. The more direct sunlight it gets, the quicker it will charge up. This makes sense, as the suns power is most potent during the day, hence why your solar light will only be charging during daylight hours.
You can also place your solar light in a sunny area outside if you cannot put it by a window and want to make sure that it is fully charged for nighttime use. However, be aware that the suns rays can be powerful on sunny days and cause damage to your skin and eyes.
Another tip is to keep your light facing the sun at all times. When the solar panel is resting on its stand, make sure that its facing the sun even when you think it might have reached full charge! If you need to move your solar light after its reached maximum charge, simply unplug it and turn it off before moving it, then do the same when placing it back down or plugging it back in.
If its the first time charging your solar lights then read here for a more in-depth article.
Situation One: Cloudy Days
Cloudy days can really get in the way of your solar lights charging to their maximum potential. That doesnt mean that your lights will not charge at all, but they just dont benefit from the same power that full sunlight exposure can provide. The best way to go around this is to use an amorphous solar panel, which is a great alternative to monocrystalline or polycrystalline solar panels.
For the most part, an amorphous solar panel isnt as efficient as the other two options, but it is more effective in capturing sunlight even if the weather outside is a bit cloudy.

Do Solar Lights Charge On Cloudy Days
The short answer is yes! Although direct sunlight is key to charging solar panels, they continue to charge even on cloudy, overcast days. Sols innovative lighting systems and products, for example, are designed to work for at least four days with no direct sunlight! This is what we refer to as the autonomy of our system. Four days is what we consider to be the industry standard.
Which Solar Panels Work Best In Cloudy Conditions
Solar panels that are more efficient will produce more energy in the cloudy conditions.
This is true for all types of PV cells used in solar panels. Some solar cells can capture more UV light than others, including the red and blue wavelengths. This allows for higher energy production even in cloudy days.
SunPower panels are the most efficient panels and can produce more energy than the ones below them. The backside mirror is a thin aluminum layer that bounces light photons back into the solar cells. Light has a second chance to absorb.
This increases your energy output, especially when you have limited UV light hitting your panels.

Do Outdoor Solar Lights Work In Extreme Weather
As a general rule of thumb, solar lights can be used all-year round in various temperatures.
While many people note that their solar lights may not work as well in the winter, this is likely more attributable to the cloud cover than it is to the freezing cold. In fact, some solar lights may actually work better in the cold than in other types of weather, as they function more efficiently in cold weather than in hot weather.
While there is no set temperature that you should bring your lights inside for, you should keep a watch on other elements of extreme weather, both hot and cold. For example, high-speed winds might knock them over, or large amounts of snow could cover them up, greatly reducing their ability to effectively perform at a high brightness level.
If you do decide to bring your lights in to store during such times, make sure that they are in the off position and stored in a dark place.

Do Solar Lights Work In Shade
The simple answer is, yes they work under shades.
The only thing solar panels need to work on is sunlight so the panels do not have to be always placed under direct sunlight. But when you are placed under the shade, the amount of sunlight it will get will be decreased. So this will decrease the efficiency of the solar lights. But it does not make solar panels completely useless.
But if you placed solar lights in a very dark area it will decrease the efficiency a lot. So always try to place the panels in an area with an adequate amount of sunlight. From that, you can get the best out of it.
How Do Solar Lights Charge
Solar lights consist of solar panels that enable solar energy to generate power. The generated power is then stored in a rechargeable battery which typically comes as a set with solar panels and lights. The set also has an intelligent controller that prevents the battery from overcharging.
The smart controller is responsible for switching solar lights on and off or charging. Specifically, the controller can detect when there is available sunlight for charging during the day. As day turns to night, it automatically turns on the solar lights and vice versa.
The rechargeable batteries store energy daily when there is available sunlight through the controllers guidance. As night arrives, batteries release the stored energy to emit light.
