Top 7 Solar Panel Faults

If you choose a solar energy system, you should be able to reap its benefits with minimal effort. Solar panels are relatively low-maintenance.

Despite this, nothing can be guaranteed to work. It’s important to take swift action once you detect a problem with your system’s operation to prevent the escalation of existing issues.

Here we’ve listed some of the most common problems affecting solar panels:

Hot spots on the panels: Hot spots are places where the panels are overloaded and get warm. Hotspots on solar panels are typically produced by poorly soldered connections or a mechanical defect in the solar cells.

The PV panel’s performance and longevity are decreased by this phenomenon, which can ultimately result in a short-circuit.

Roof issues

The solar system should not affect the structural integrity of your roof. On the other hand, it can function as a protective covering for the roof materials beneath. However, there are specific circumstances when the installation can negatively impact your roof. Make sure to check your roof every so often and call the people who put in your PV system if it seems to be damaged in any way.


The occurrence of “micro-cracks” in crystalline PV panels is a condition that happens commonly. These small tears in the solar cells are virtually undetectable.

Micro-cracks can appear during the manufacture of PV modules, but they can also happen during transport or as a result of sloppy handling techniques during installation. Larger micro-cracks will cause damage to the solar cells, resulting in production loss.

Potential Induced Degradation effect

Potential Induced Degradation effect

PID can occur due to the voltage difference between the earthing and the solar panel. When this happens, the primary power circuit ends up producing partial voltage discharge. PID effect may degrade the efficiency and performance of the panels and lower their lifespan. Luckily, a solar professional can help to reverse or prevent the problem.

Internal corrosion and delamination

Internal corrosion (rusting) occurs when moisture penetrates into the panel. Panels must be air- and water-tight. In order to achieve this, the components of panels (the glass layer, the solar cells and the back sheet) are laminated under vacuum.

 However, if the lamination process has been not done properly or was too short, this can lead to delamination during operation.

Delamination is the detachment of the laminated components. Delamination – but also incorrectly fitted module trim. Moisture leads to corrosion, which becomes visible as darker spots on the panel.

Snail trail contamination

  • The contamination known as “snail trails” is another common issue with solar panels. The name derives from the brown lines on your panels, which give the impression that snails have crossed the surface.
  • Snail trails are caused by a number of circumstances, including poor silver paste, and often appear only after a few years.
  • This leads to moisture, which in turn causes oxidation between the encapsulating material and the silver paste.
  • Additionally, tiny flaws in the PV system could cause contamination from snail trails. The issue lowers the solar system’s efficiency and hastens its early failure.

Inverter problems

  • Solar panels require an inverter to convert the direct energy produced by the sun into the alternating current that your home now uses. An inverter resembles a box and is frequently put on the upper floor.
  • Inverters are not as durable as solar panels, which typically have a 20-year lifespan. It has been reported that inverters used in solar energy systems need to be replaced every 10–15 years.
  • PV systems can be incredible powerhouses, but they are not flawless. They are susceptible to manufacturing flaws and deterioration, just like any other device.
  • The most important thing is that you be aware of how your system works and what it produces, and that you promptly report any changes.

If you suspect that your solar modules are suffering from one of the problems listed above, we can help you specify and execute specific tests in order to identify and potentially mitigate them.

Solar Panel Maintenance Checklist

If you have solar panels installed in your home, these are probably the questions you will want answers for!

How do I know if my solar panels need maintenance?

The best way to identify solar panel maintenance issues is to check if the system is generating the optimum energy. Compare your recent electricity bills with those from the previous few months or years to obtain it. Output data is also shown in the monitoring application.

It is a warning sign that your solar panels require maintenance if you find significant deviations from the normal or discrepancies in their performance.

You’ll have to do a few basic tasks to maintain your solar panels in good condition, but most of the time, keeping your solar panels is simple and few things you can perform on your own.

Let’s look into some of the important Solar Panel Maintenance checklist

You should always have a maintenance checklist for your solar panels on standby so that you can do timely inspections and identify any defects. Your checklist should include the following:

Visual inspection:

solar panel maintenance and repair
  • Debris removal from surface of the panels (such as leaves and nesting material).
  • Remove any dust or dirt that has accumulated around the inverter.
  • A build-up of dirt in the inverter’s heat sink acts as an insulator, reducing the inverter’s performance and lifespan.
  • Whether any of your panels have faded in colour, cracked, or become cloudy, you should contact your provider to see if they need to be replaced.
  • Frequency of inspections recommended once in every 6-12 months.

Electrical inspection:

This can be done by a solar maintenance professional to ensure that:

  • The earthing point and earth cable are connected and free of corrosion.
  • Rooftop isolators are not damaged by heat and the inverter is functioning normally.

Remove potential dangers: PV panels are vulnerable to shading; any overhanging tree branches must be removed to prevent any hazards to the panels. If you notice any trees growing too large since the system was built, cut them down.

Clean your solar panels: Sloping roof installations are generally washed by natural rainfall, although those on flat roofs or in places with drastic pollution or debris need be cleaned at least once in every twelve months; however, this depends:

  • pitch of panels.
  • proximity to dust sources.
  • frequency of rain events.

Track the Performance of Your panels:

Compare performance data with the preceding week, month, and/or the same period last year in order to assess performance. It is recommended to check the performance of your solar panel once in every six months in order to identify issues earlier and fix problems, if required.

Maintaining a logbook:

If you want to keep your solar system in a good condition, it’s always necessary to keep a track of any maintenance work done. This can also include inspecting and cleaning parts, or replacing them if necessary.

You can extend the life and increase the performance of your solar panels by following this simple checklist. Simple upkeep protects your solar investment.

Get your panels serviced – We highly recommend that you do this at least once every year. Solar panels must be maintained in order to last as long and generate energy at a high rate of efficiency.

GST Rates & HSN Codes for Solar Rooftop Products


GST Rates and HSN Codes for Solar Rooftop Products in India

HSN (Harmonized System Nomenclature) Number and SAC (Services Accounting Code) Number got its place as a new column in invoices for Solar Equipment after the implementation of the GST. Yes, it is mandatory to give a column in invoices for HSN/ SAC. Confused? Here’s an attempt to make it simpler for you.

Solar energy has been emerging as a progressive and effective power generation alternative for residential, commercial, industrial use. Government policies have so far have remained favorable, and this had an advantage for the solar industry to have a 3-fold increment on Year-on-Year basis. The GST rate for the material used for equipment stood at 5% and it was making a smooth progress. Customers were understanding the need and have been inclined to buy such solar solutions that help them reduce their dependence on grid power.

But now as per government’s new norms, from October 01, the GST rate will be 12%, due to which the price of solar power equipment will increase by 7% – 10 %.


What has HSN and SAC got to do with the GST?

We all know that GST is Goods and Service Tax. Which means the tax on Goods or Services or Both. HSN number is used to classify the Goods that come under GST into “22 sections and 99 chapters”. SAC codes are similar to HSN codes and have been used since before implementation of GST.

Why HSN and SAC?
GST is followed in around 160 countries out of 196. Globally, most of them follow similar HSN/ SAC codes with a very slight difference between one another. This helps in attracting foreign trade as (import or export) by easing the taxations.

How is HSN code classified?

It has 21 sections with 99 chapters, 1,244 headings and 5,224 subheadings. They are arranged based on the product degree of manufacture or in terms of its technological complexity. The natural products that include plants and animals come under the initial sections. While the man-made or technologically advanced products that include machinery come later.

The HS comprises approximately 5,300 article/product descriptions that appear as headings and subheadings, arranged in 99 chapters, grouped in 21 sections. The six digits can be broken down into three parts. The first two digits represent the chapter the goods are classified in, e.g. 09 = Coffee, Tea, Maté and Spices. The next two digits identify groupings within that chapter, e.g. 09.02 = Tea, whether or not flavoured. The final two digits are even more specific, e.g. 09.02.10 Green tea (not fermented). All countries classify products in the same way, upto 6 digits filtering (a few exceptions exist where some countries apply old versions of the HS).

Every section is a collection of various chapters. The sections represent broader classification of goods and chapters represent a smaller section that filters down to particular product section.

In order to identify the goods better, India and some of the countries use this 8 digit code for a more specific classification. Some of the HSN codes use dashes in the beginning of description which denotes an article that belongs to a group covered under a heading. A double dash indicates that the article is sub-classification of the preceding article that has a single dash.
