When you invest in solar panel installation, it feels great, lower electricity bills, reliable power, and the satisfaction of using clean energy. But here’s the thing many people forget: solar panels are not “install and forget.” though we agree that the life span of solar panels is supposed to be 20 - 25 years. Just like your bike or car needs regular servicing, your solar panels also need some care to keep performing well for years.
In fact, one of the most common questions people ask is – “Why do solar panels need maintenance?” or “Why is solar panel servicing mandatory?”
The answer is simple: without servicing, your solar system won’t give you the benefits you expect. In India, where we face dust, heat, rains, and sometimes power fluctuations, solar panel maintenance service becomes even more important.
In this article, let’s look at the 10 signs that tell you your solar panels need maintenance and why it’s worth paying attention.
Think of solar panels as the heart of your solar system. They sit outside, facing the sun all day, every day. That also means they face dust, rain, heat, and even bird droppings. Over time, these things reduce their efficiency.
Here are some reasons why solar panels maintenance servicing is a must:
So, servicing is not an extra cost – it’s actually a way of protecting your investment.
Now, let’s come to the main part. How do you know it’s time for servicing? Here are the 10 clear warning signs:
If your bill suddenly looks higher even though your usage is the same, it probably means your panels are not generating enough power. That’s the first big sign they need a check-up.
In most Indian towns and cities, dust is everywhere. Add bird droppings and leaves, and your panels can quickly get dirty. Even a thin layer of dust can reduce output by 10–20%. If you can see the dirt, it’s time for cleaning.
One reason could be that your panels have gotten shade, this could be due to a tree that has grown or maybe in some cases a new building got built. And this will lead to a drop in power generation for your panels. A technician can adjust the angle or suggest the right solution.
If there has been some storm, or anything as such and for some reason your panels have gotten scratched or even small cracks, minor or major, they’ll let moisture inside and will damage the solar cells. Always get them checked if you notice cracks.
After heavy rains, if you see water inside the panel frame or around the wiring, it’s a danger sign. Moisture can short-circuit the system. In that case getting servicing then will be a very good choice.
If you have an off grid solar system, the inverter is like the “brain” of your solar system. If it makes strange sounds, or shows red/error signals, it means something is wrong with the panels or the wiring. Don’t ignore it.
If your bill has suddenly shot up for no reason, it means your solar isn’t generating enough. This is one of the most common signs people notice before calling for servicing.
In India’s humid or coastal areas, wires and joints can rust over time. Loose wiring not only reduces efficiency but can also be a safety risk.
Solar panels get hot, but if they are too hot to touch and you notice low performance, there may be a ventilation issue. Servicing will help identify and fix this.
See, we know that solar panels last at least 20-25 years but that doesn’t mean they won’t need our help surviving. If your solar system is more than 5 years old and hasn’t been serviced, it’s time. Even if it looks fine, small issues may be hiding inside.
Let’s put it simply. You spent good money on installing solar panels because you wanted savings and reliability. Without solar maintenance service, your system won’t deliver what you expect.
Here’s why maintenance is needed:
