What is Robotic Cleaning of Solar Panels? Pros and Cons

If you want to harness energy from the sun, using solar panels is one of the best ways to do it. However, it needs daily maintenance to be working efficiently.

The reduction in efficiency is mostly due to the dust that accumulates on the surface of the modules when no cleaning is done for months.

Residential systems (usually ranging between 1 to 5KW) can still be maintained and cleaned with a wiper or a brush. But it’s difficult to clean all the dust manually with a commercial solar panel system.

For commercial systems, hiring an expert team might seem to be a viable choice but that is quite an expensive and time-consuming task. Here is where automatic or robotic cleaning of solar panels comes in.

What is Robotic Cleaning?

Robotic cleaning is a way of cleaning solar panels without the use of water. The robots use dry brushes and air pressure to clean the PV panel.

Though cleaning with water is a more effective way of cleaning solar panels. But still, considering the lack of abundant water supply at places makes it difficult for cleaning the water systems manually. For that, robotic cleaning can be a great choice.

On top of that, doing wet cleaning of panels on a regular basis requires a lot of manpower, a great amount of water, incurring a lot of expenditure.

However, robotic systems are available to work each day.

Having said that, there are a few pros and cons associated with robotic cleaning that you must know before you invest in a robotic cleaning system. Here are a few of those.

Pros and Cons with Robotic Cleaning Systems

Like any other electronic device, a robotic cleaning system has its own advantages and challenges. Below we have discussed them. Go through them before you install a robotic cleaning system for your solar panel.


Save water: Installing a robotic solar panel cleaning system can be a great way to save water. Clean water, being one of the most precious things today, dry cleaning of solar panels using robots is a fantastic choice.

Cost-effective: Robotic cleaning systems just require a fixed initial cost and little maintenance. It can be really a boost for larger, commercial solar panels where a lot of trained manpower and a lot of expenditure goes into cleaning it.

Clean every day:

With robotic cleaning, you can clean your solar panels every day. However, this is difficult if you go for manual cleaning. If not impossible, it will take a lot of expenses and manpower to clean the panels every day.


Less Effective:

In comparison to cleaning with water, dry cleaning is less effective. This is because a medium like water has the property to wash away the dust completely.

High Initial Investment:

The initial investment in the case of robotic cleaners is quite high. So, it’s not ideal for residential use.

Electricity cost: Robotic cleaners use electricity to operate and that adds as an extra cost.

New technology: Robotic or dry cleaning is a comparatively newer technology and much research must still be done for it to run to its full potential.

So, that was all about the robotic cleaning of solar panels and the pros and cons of it. It’s quite a good alternative to cleaning with water and the advantages outweigh the cons by a large factor.

However, being a new technology, there is still a lot of development needed. Usage of AI can be one thing that still needs to be implemented.
