What Is A Low Light Solar Panel And Who Is This For


Having a solar power system is advantageous because it can provide you with electricity using just the sun’s energy. But that is also precisely one of its apparent limitations – solar panels work well only with direct sunlight.

The whole point of installing a solar panel system is to have it exposed to direct sunlight to generate electricity.

One of the factors you need to consider and significantly affects your solar panel’s performance is the shade and sunlight your panels receive. Conventional solar panels rely much on sunlight and might not work well in areas that receive little to no sunlight throughout the year.

Fortunately, with the advancement of technology, low light solar panels are now made available. A low light solar panel, as it is called, is viable and efficient even in areas with low sunlight. It can efficiently generate power even on a shady or cloudy day.

Suppose you live in a region with less sunlight availability but would like to have your solar power system for that off-the-grid power source. In that case, a low light solar panel is your perfect option. You are sure to have your much-needed power supply available even with scarce sunlight.

A low light solar panel can be installed wherever you want. You never have to worry about the shade or the weather. This is an excellent system for your RV, boat, or car for that backup power you need.

How Does It Work

Solar power systems have become more mainstream today. You can see a lot of different brands coming out with their models of low light solar panels. They have become popular among homeowners because they serve as a convenient source of power with low maintenance costs. And you only need sunlight to make it work. But how exactly do low light solar panels work?

Solar panels are installed in an area where they can receive sunlight. The panels then absorb and transform solar energy into electricity through the photovoltaic effect. Solar panels have silicon photovoltaic cells responsible for converting the radiation from the sun into electric power.

When the solar radiation is absorbed and interacts with the photovoltaic cells, the electrons begin to move, thereby creating an electric current. The generated power is a direct current.

Before it can be used to power up your devices or appliance, it is first converted into alternating current using the inverted technology in the solar panel system.

Most low light solar panels you can see in the market today feature monocrystalline solar panels. This solar panel technology is known for its high efficiency and power capacity, even under dim light conditions.

Another critical feature that significantly affects the efficiency of low light solar panels is the bypass diodes.

These bypass diodes help reduce power drop due to shading or low light conditions. Solar technology is still developing, but the low light solar panel is an excellent innovation from the standard solar panels.

Advantages And Disadvantages Of Using A Low Light Solar Panel



  • Works well under poor light conditions

One of the apparent benefits of using a low light solar panel, especially compared to the conventional ones, is that it works even in areas that receive less sunlight throughout the year.

Frequently Asked Questions


Is there a solar panel that works at night?

The whole point of a solar panel is it absorbs solar energy and converts it into electricity. Following that logic, solar panels are useless at night when there is no sunlight.

Even with our advanced technologies, there is yet to be invented a solar panel that works at night. But with further research and developments, a solar panel that works at night is not far from becoming a fully functional reality.

Studies have been done on this matter, and a recent paper co-authored by Jeremy Munday, a professor at the Department of Electrical and Computer Engineering at UC Davis, has cracked the code.

A new solar cell design capable of generating 50 watts of power per square meter is on the works. This power output is equivalent to a quarter of a conventional solar panel generated during the day.

This new thermoradiative cell works in reverse to a typical solar cell that absorbs light from the sun. The new cell radiates infrared light towards the cooler outer space that then generates electricity. Prototypes of these new cells are still being developed. But just imagine a solar panel that works throughout the day. It is a step closer to overcoming one of the main limitations of solar panels.

Do solar panels work in the shade?

A common misconception about solar panels is that it doesn’t work in the shade. However, although shading does affect its efficiency, solar panels still do work in the shade.

There are various sources of shade to solar panels. It can be due to cloudy weather, the trees near the solar panels, or the nearby roofs or buildings. These can affect the amount of power your solar panels can provide. But how exactly do these affect the performance of your solar panels?

As mentioned, solar panels have solar cells absorbing the sunlight that hits on the panels. But in the shade, these standard solar cells will not work effectively and cannot generate sufficient power. The power loss depends on the amount of shade that hits your solar panels. If half of the solar panel is in the shade, then the panel’s efficiency will be reduced to half.

Not only the efficiency but also the lifespan of your solar panel will be affected. When part of the solar panels cannot work due to the shade, the other parts will have to double its capacity to compensate for the power loss. This might result in overheating and permanent damage to your solar panels. That is why, for shady areas, low light solar panels are highly recommended.

Are polycrystalline solar panels better in low light?

No, polycrystalline solar panels are not better in low light than monocrystalline photovoltaic cell panels. On the contrary, this type of solar panel is less efficient in converting solar energy into electricity, no matter the weather.

To be specific, in optimal conditions, polycrystalline cells’ efficiency is 13-16%, whereas monocrystalline is at least 20%.

In general, solar panel efficiency on cloudy days will decrease by 10-25% of its average power input. For example, a 100 watt solar panel output will be down to 75 to 90 watts. However, as monocrystalline cells are more efficient than polycrystalline, they can still perform better than their counterparts.

Hence, the top-rated solar panels for cloudy days should have monocrystalline cells.

What is the minimum light for a solar panel?

Manufacturers test their solar panels under three test conditions: 25℃ photovoltaic cell temperature, 1000 watts per square meter solar irradiance, and 1.5 air mass. Hence, determining the minimum light requirements for a solar panel in real-world settings can be tricky because the parameters are never constant.

In theory, solar panels need a minimum of four hours of direct sunlight daily. Sunlight can produce at least 6,000 lumens on a bright and sunny day. However, placing the solar panels in a shaded area may receive only around 1,000 lumens. In cloudy weather, the sun’s luminous intensity will reduce to about 100 to 3,000 lumens.

So, four hours of sunlight exposure on an overcast day may not always be enough. While solar panels don’t need direct sunlight and can convert energy from artificial lighting, it can be counter-productive to charge the solar cells using electricity.

How long do low-light solar panels last?

Solar panels that work on cloudy days should last as long as other photovoltaic cell systems for sunny weather. They can stay operational for at least a quarter of a century, with a half-percent average annual degradation.

For instance, a 100-watt solar panel will only produce 99.5 watts in its second year, 99 watts in the third year, and so on. You can deduct 0.5% each year from the solar panel’s power output to determine how long the solar panel will last.

Solar panel type can also impact its longevity. Monocrystalline solar panels last longer than polycrystalline and thin-film versions because they have more robust construction and greater efficiency, regardless of weather conditions.

How to use & install?

Installing a solar panel can be tricky, especially if you have zero knowledge of wirings and electronics. Add also the fact that some products do not come with a clear and simple instruction manual. But here is a general guide on how to use and install your solar panels.

  • Plan out the area where you want to install your solar panels

First things first, you must think of where you want to put your solar panels. It can be anywhere you want if it gets enough sunlight and away from any shade sources to work correctly.

You need to measure the solar panels’ dimension itself to find a space that you can fit them.

Plan on mounting it on the roofs or other elevated areas. You also must make sure that the structure can support the solar panels’ weight to avoid any accidents.

  • Install the physical supports and solar panels

After determining the exact area where you want to install your solar panels, it is time to put on the supports. There are brackets for sloped roofs and mount rails on flat surfaces. Make sure that it is tight and secure. After making sure that it is secured, you can mount the solar panels on the supports. Position it in an angle that gets maximum sunlight exposure.

  • Connect the wires and electricals components

Make sure that the wires are correctly well insulated to avoid unwanted accidents. The top-tier solar panels for shaded areas include the necessary cables and connections that you need for your solar panel. Make sure that connections between the different components are correctly connected.

That is what you need to do to install your solar panel. You can now do your test run and see if your solar panels work.


The best low light solar panels work even when structures, buildings, or trees cast partial shadows on them. Their efficiency and power will not drop, but instead, keep on working as they should. They are designed to handle a drop in the sunlight they receive and work even in the shade.

To find the right solar panels for shady areas, compare their features, weigh your options, and determine your needs. Which among them can offer just the sufficient power amount for your requirements? How easy or difficult is the installation? What about maintenance? Nevertheless, know the basics to set your expectations and avoid any surprises. Refer to the above buying guide for help today!
