Low-lighting and cloudy environment are holding you back to save the planet – or that’s what you might think. There has always been a misconception regarding solar panels that they can’t perform well in low light, and their efficiency drops so much that it is a bad investment. If you are bothered by this, then we have good news for you. Because now there are low-light solar panels that can perform insanely well under bad climate, cloudy weather, or in low lights. So, if you are looking for panels to work in low light or shaded situations, then our pick of best low-light solar panels is just for you!
How Low-Light Solar Panels Works
Before going through the nitty-gritty details of the best low-light solar panels, you should understand how the solar panels function to know what you need to look for and what you are getting into.
Solar panels generate energy revolving around the PV or photovoltaic system, and the PV system doesn’t require heat to function; instead, it needs light, and if it gets an adequate amount of light, it will perform the same whether it is in a low light situation or under the bright sun.
When the light hits the PV cells of the solar panels, they generate light or solar energy to DC, which follows through the cables to the inverter to get converted into AC, which we later use as the source of electricity.
If the cells receive enough light in this scenario, the solar panels will work at their maximum efficiency. So, you need to ensure that your panels are receiving their required amount to perform. Not overflowing sunlight as overheating might damage the PV cells located in the panels.
Now that you have a clear concept of how low-light solar panel functions next, you need to know about the attributes that you need to keep a lookout for when selecting the best low-light solar panel for yourself.
Types of Solar Panel
Traditionally, solar panels can be divided into three types.
- Monocrystalline Solar Panels
- Polycrystalline Solar Panels
- Thin-Film Amorphous Silicon Solar Panel
There are various mix and hybrid types out there, but for low-light solar panels, the best of the best is monocrystalline solar panels due to their high efficiency and smooth power generation.
Hybrid models, a mix of monocrystalline and amorphous solar panels, are also a good option for low-light solar panels. They provide the best of both panels and ensures a reasonable efficiency rate and durability. Also, they come in cheap than a proper monocrystalline solar panel.
When it comes to low-light solar panels, the higher the power capacity is, the better. A light solar panel that needs more than 100 watts is regarded as the best power choice for low-light panels. The panels which have a capacity greater than 100 watts are called high-powered panels.
A proper low-light solar panel must come with bypass diodes. A standard solar panel has around 60 PV cells connected; here, the wiring is connected in series, so when the light comes in contact with the PV cells, they generate electricity from start to finish.
So, if a portion of the solar panel gets shaded or doesn’t receive light properly, then that cell builds up electric resistance, which blocks the flow of electricity generated from the other cells.
That’s where bypass diodes come in. Bypass diodes create an alternate route around the shaded cells that create resistance so that the flow of electricity stays uninterrupted and the solar panels can work properly.
Therefore, without bypass diodes, solar panels will lose a good amount of efficiency, especially if working in low light situations.
