Most of the issues with the performance of solar panels are related to the production of electricity. That is why most installers recommend that you monitor the production of your system. When you pay close attention to the changes in the production of electricity, you will proactively identify the issues and address them. 

1. Solar Panel Cleaning 

So many people still wonder whether they need to clean their solar panels. Since these systems are normally installed at an angle on rooftops, rainwater tends to clean them naturally. However, if you reside in an area that is characterized by dirt, dust, and smog, you will record a reduction in your production over time. 

Check Time To Time

The main remedy to this problem is cleaning your solar panels from time to time. If you are not sure how to do this, it is advisable to hire a professional cleaning company to do this work for you.

That is why it is important to know how to clean and clear this debris. The accumulation has a negative impact on the amount of energy that the energy solar system will generate per month. It will, in turn, affect the monthly solar savings that you get. 

  • It is better to occasionally rinse your solar panel system with a garden hose than to do nothing. If the water that you are using is not treated, it can leave behind grime or residue. 
  • The other common problem with solar panels is streaking, as is the case when washing windows. You only need to clean the solar panels during particular times of the day i.e. when the weather is not too hot.

2. Internal Malfunction Fixing

There are so many internal malfunctions that happen to solar panels. These include shoddy workmanship, glitchy inverters or panels, and faults in the wiring systems.  All this tends to reduce the savings in your wallet and cause performance dips in the system. 

  • Remember, each time you put an electronic gadget outside exposes it to adverse elements like heavy rains. This, in turn, increases the chance of this item getting broken. 
  • The beauty of solar panels and their components is the fact that they come with a warranty. However, you may have to pay for the removal of faulty panels from your pocket and then get free installation replacements. 
  • The sad news is that the warranty does not often cover workmanship and wiring. Therefore, you have to read through the warrant requirements carefully before you purchase a solar panel system. Check whether the solar panel maintenance covers most of these issues. 

Whether the solar panel is fully covered or not, make sure you correct all the underlying issues to get maximum benefits from the system.

Tree limbs, hail, and hurricanes, among the other “Acts of God,” can either dislodge or break the solar panel. It is something that can hamper your savings severely and end up damaging the roof.  

  • Most warranties don’t cover this kind of damage. However, there are so many insurance policies that include solar panel protection in their package.
  • Therefore, you need to check the solar panel maintenance clause with your homeowner’s insurance. It is good to confirm whether they cover your solar installation or not.

There are manufacturers who also provide an extra warranty that guarantees you a higher level of output for a short period. For instance, it can state that the production will not be less than 90% of the initial output in the first ten years. 

Solar panels typically have a workmanship warranty to protect you against any defective parts. In most cases, this warranty will cover you for the first five years of operation.

Solar inverters also come with an average warranty of ten years. With these warranties, you will pay either little or no solar panel maintenance costs over the system’s lifespan. The attractive warranty is among the main selling points that solar manufacturers have at their disposal.
