What Color of Light Is Charging a Solar Panel

Solar panels are quickly becoming one of the most ubiquitously installed and residentially applicable forms of renewable energy access out there, to the point where continued price drops have made these panels a reasonable investment for many households.

But if you’re to install a number of panels on your roofing system, it’s a good idea to be informed about what they do, how to get the most out of them, and why they’re installed in this manner in the first place.

Believe it or not, solar panels do not respond to all forms of light, as some wavelengths in the infrared spectrum are not potent enough to provide the panels with the light they lead. While some might be familiar with UV light (the kind of light that can detect stains and other cleaning worries), they are too potent with energy to the point where solar panels cannot properly handle them.

So, if solar panels require only a specific band of wavelengths in the light spectrum, what are they?

What color of light charges a solar panel?

Red to violet wavelengths provide enough energy for a solar panel to convert to electricity, which can ultimately bring down your energy costs. Funnily enough, solar energy isn’t necessarily ‘renewable,’ as the sun will die at some point, but thankfully, none of us will have to experience that and no regulation requires manufacturer warranties to last that long. 

How can you improve light exposure?

It’s very important to face your solar panels to the sun as much as you can during the day. Depending on where your house sits, this may mean installing them on one or another side of your home to make use of its natural orientation. While we may think that solar panels have to be installed on a roof, that’s not necessarily the case in wide-open environments such as open-plan fields where mechanisms can be installed to track the sun, but in residential areas, this heightened installation area will ensure there is little in the way of construction blocking it. Your solar panel will also be installed on a mount to make sure it’s leveraged correctly.

What about cleaning?

One of the best ways any homeowner can care for their solar panel after installation is to make sure that they’re cleaned semi-regularly. Even in relatively clean and construction-free environments, dirt and dust can accumulate, as can the conditions retained from intensive weather effects.

Solar panel cleaning kits exist for homeowners to use light brushes and biodegradable soap solutions in pursuit of cleaning this installation properly. But it’s not always enough and it can be quite awkward to access your roofing system with the correct harness and ropes a professional might use to secure safety. For this reason, it’s healthy to ask if your solar panel installers also offer a cleaning service, or if they have any cleaning advice for your particular installed model.

With this advice, we hope you can make the most of your solar panel and ensure their maximum contact with the light wavelengths they need for optimal function.
