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.

Battery Maintenance Checklist

One of the most effective ways to extend the life of your solar batteries and reduce the lifetime cost of your off-grid solar electricity system is to maintain them properly. Maintenance of batteries focuses on proper charging, electrolyte condition, battery terminals, and safety.

When you take good care of your batteries, they will last longer and perform better. Battery life relies on parameters like storage temperature and depth of discharge (DOD).

Here’s a checklist for optimal battery performance and maintenance-free batteries:

Things to Know Before Starting:

Before you start maintenance, make sure all the safety equipment is ready to go. The following is a list of typical maintenance tools you will require.

  • Hydrometer;
  • Glass bulb type thermometer;
  • Distilled water;
  • Handheld voltmeter or multi meter;
  • Anti-oxidant coating;
  • Hand gloves and protective eyewear;
  • Baking soda – for cleaning of batteries.

Prevent unauthorised access:

Batteries should be placed per manufacturer instructions. The battery bank must be safeguarded by a proper enclosure that is only accessible to authorized personnel. Proper safety signs should caution people about the risks.

Check the battery:

A comprehensive and detailed visual inspection of the battery is needed as part of routine maintenance. This inspection should also include:

  • cleanliness of batteries;
  • level of electrolyte;
  • condition of battery terminals;
  • signs of any electrolyte in the safety trays on the floor, indicating a battery leak or overfilling;
  • condition of battery containers; and
  • battery voltage level.

Charging your batteries

To maximise the life of a battery bank, it is best to ensure that it is regularly receiving a full charge. Some solar lead acid batteries can go down to a maximum depth of discharge of 70- 80% while, for some deep cycle lead acid batteries, the recommended maximum depth of discharge is 50%.

  • For flooded batteries, the battery bank also requires an equalisation charge to ensure that all individual cells in the bank are at a similar charge. This is achieved by charging the battery until bubbling or gassing occurs.
  • The period between equalisation charges is dependent upon manufacturer and typically vary from 7–28 days but some batteries can be as high as 90 days. Please check with your system supplier.

How To Check the Fluid Level

The only type of battery that requires this procedure is a flooded lead acid battery (FLA). Open the top of your battery and look inside. To ensure that no metallic lead surfaces are visible, the cells should be filled with distilled water.

Most batteries contain a “fill line” that indicates the proper electrolyte level. The maximum liquid level is about 1/2 inch below the cap. Do not overfill your batteries, since this could cause them to spill!

How To Check the Charge Level           

  • Determine the state of charge or depth of discharge (DOD) by checking the specific gravity and voltage of the battery.
  • The specific gravity table below will help you determine the state of charge of your battery.
  • If your batteries are 6V instead of 12V then simply divide the voltages by two. Similarly, double the voltage values for a 24V system.
  • If you do not properly monitor these two factors, your battery will undergo significant sulfation.

Battery Tests:

After you finish visually inspecting your batteries, there are two important tests you should do as part of regular maintenance: 

  • Open Circuit Voltage Testing and
  • Specific Gravity Testing.

Performing these tests monthly will give you with key information regarding the condition, lifespan, and charging level of the batteries. Additionally, they will assist you in identifying issues like overcharging, undercharging, and overwatering. Identifying these issues early is crucial for maintaining the condition of the battery.

Cleaning Batteries:

  • Cleaning the battery terminals on a regular basis requires a mixture of baking soda and distilled water applied with a battery terminal cleaner brush.
  • Then, rinse the terminals with water, ensuring that all connections are secure, and apply a commercial sealant or high temperature grease to the metallic components.
  • Clean up the space around the batteries; it should be dry and well-organized.

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. And triple dash indicates that the article is a sub classification of the preceding article that has a double dash or triple dash.

SAC code in GST

SAC and HSN are the similar codes under GST. In case of services, for each type of service provided is given a unified code for recognition, measurement and taxation. These are known as SAC codes. In the current service tax regime, SAC codes are already defined for each type of service.

  • The small dealers under composition scheme will not require to mention SAC codes in their invoices. The codes will be mentioned in invoice and in the GST tax return details which will be uploaded on the GST portal.
  • The small business under composition scheme will not be required to mention SAC codes in their invoice.

Services will continue to be classified under Services Accounting Code (SAC) which is issued by the government for service tax. This is expected to remain in GST regime.

How it affects Solar Industry?

Though our Honourable Prime Minister Mr. Narendra Modi has announced in his speech that all Renewable energy equipments will be taxed 5% GST, traders are confused as there have been no written statements or Orders passed yet which has stalled the market since a week.

As per our understanding, HSN Numbers and GST % are as follows:

This May we had published a preliminary guide on expected GST rates for the rooftop solar industry. Now that the dust has settled, the final rates are clear. Below information serves as a ready reference for the GST rates 

applicable along with relevant HSN codes for the solar industry in India:

Item HSN/SAC Code GST Rate Applicable
Battery 8507 28%
Solar Module 8541 5%
Charge Controller 8504 28%
LED Lights 9405 12%
