How to maintain Solar Panel for better efficiency?

How to maintain Solar Panel for better efficiency?

The hustle doesn’t end merely after successful installation of solar panels. They require periodic monitoring for ensuring optimal performance and security. But the good news is, their maintenance costs are minuscule when compared to the benefits they provide in terms of power supply, energy saving, emission control, sustainable option and also being pocket friendly. However, a bit care can pass an extended way. 
Regular upkeeps will prevent you from hefty maintenance costs down the road, and sustain your panels exceptionally well.

Be mindful in checking up following aspects so you don’t have to compromise with their efficiency later:

Be mindful in checking up following aspects so you don’t have to compromise with their efficiency later:

Dirt and Debris accumulation

If your solar panels are tilted then you don’t have to go an extra mile to clean the dirt or debris because the rain itself cleanses the area. It is of paramount importance to keep the panels clean so that it doesn’t obstruct the solar radiation eventually compromising the performance. However if there are extended periods without rain then it is recommended to clean your panels two to four times per year. But if somehow your location encounters snowfall you need a hand with extra maintenance since the panels are made up of tempered glasses and temperature disparity affects its efficiency. So it’s better to get rid of any debris from the panel.

  • Watch out your mounting and roof penetration

The mounting racks have an important role to play in the efficiency of solar panels. The components are examined properly to ensure the durability and soundness of the structure. In case you come across any leakage do reach out your service provider instead of self-correcting it.

  • Review after extreme weather conditions

There is no doubt that the solar panels are durable and have a shelf life of close to 25 years but extreme weather conditions could possibly impact the efficiency. Although they can withstand even the hail and harsh weather, wind but if in a case they suffer any visible damage you will have to walk through the steps of either replacement or repairing.

  • System Monitoring

    A monitoring device if included into your setup, may tune about the performance of your solar panel and the percentage of carbon emission on any given day, and what is the energy yield over time. This helps you to look precisely how diverse external factors have an effect on your panel’s overall performance and how well they maintain their performance throughout the life. Not only it helps you to evaluate the performance but also alerts you in case of any impairment or malfunction so that you could actively work on their redressal.

  • Keep Solar Panel out of shade

    Ensure that your panel is out of the shade and there isn’t any hindrance in the absorption of the sunlight by the panels. The maximum exposure offers the best results.

    Now there is a very clear distinction when we talk about maintenance as there is something called as solar panel maintenance and another is PV system maintenance. The latter involves the repair and replacement of components of the system if something goes wrong. Whereas the solar panel maintenance refers to the things like cleansing the dirt off or snow to maintain the health and durability and soundness of the panels. So all we need is

  • Proper Inspection

  • Periodic cleaning

  • Proper Exposure

  • Well-functioning components

  • And keep a track of energy yield and usage.

Now Let us rule out the common problems that can lead to underperformance of your solar panel. Prior knowledge and clear understanding of the causes might help you alleviate the foreseen investment.

Yeah that’s right the good tidings continue because you don’t have to bother yourself with the maintenance part since your solar EPC Company has your back in looking after O&M of your solar panels. Half of your work is done when you decide to go with the best EPC service. Usually the Solar Panels requires less maintenance overtime if the assembling was done cautiously in the first place. If there was no bad part involved initially then you don’t have to drain yourself for its wear and tear. Since the panels are static and no moving parts so the look up is considerably less.

So the best way to mitigate even the slightest possible risk is by starting off on the right foot. When you partner with the reliable and dignified Solar EPC Company like Soleos it enhances your experience throughout the process. We provide peaceful and untroubled journey to our customers down the road. We are the best you can ask for be it in terms of installation or O & M. We have an uncompromised frame of mind towards the quality of our services. We provide our customers with the most efficient solar panels manufactured with high class German and technology with innovations at its par.

  • Micro cracks and hotspots
    They appear on the glass surface of the solar panels and they tend to grow in size with time compromising the effectiveness of the solar panel. However the lamination waterproofing and stuff are preserved despite of the cracks. The cause may be attributed to temperature disparity, weather conditions, or mishandling of the panels during shipping. Its repair depends upon the type of mounting. So it is utmost important to ascertain the level of damage that is leading to underperformance of the panels.

  • Loose wiring
    The wiring faults causes failed connections and may lead to unanticipated issues with power generation. So it is important to assess the connections with appropriate tools for a better experience.

  • Potential Induced degradation (PID)
    It occurs due to the voltage fluctuations that take place between the voltage generated by the panel and the earthling of the panel. This can affect the stability and lead to varying percentage of discharged voltage in the main power circuit.

  • Damage of inner module
    Internal damages are attributed to poor quality of products and their production. They cause potential wear and tear like discoloration of solar cells, snail trails, delamination, burning out of back and front of the solar modules. It can be eliminated by opting for better quality products in the first place so that it can outperform the other panels.

    Lightning, bad weather conditions, huge disparity in the temperature fluctuation can lead to damage of the modules. However the panels of good quality are resistant and withstand extreme conditions but if the panels are exposed to persistent conditions then the damage is unsalvageable.

Maintenance cost of solar Panels

The maintenance cost of solar system is between Rs. 1,000 / kW to Rs. 3,000 / kW. The larger the system, smaller is the per kilowatt price and vice versa. Different systems have different maintenance costs. If the solar panel is installed on a grid system then the maintenance cost is negligible because it’s a battery free system and all other components like solar panels, solar inverter, distribution boxes, AC, DC cable easily work for 15 – 20 years without much maintenance. In maintenance you will have to do periodic cleaning as dust forms a layer on top of your solar panels and doesn’t allow sunlight to hit the solar cells, which results in diminished generation of electricity and hence leading to underperformance.

The maintenance can be your look out or you are also available with the option of your partnering Solar EPC Company who can render their service of O & M of the panels after installation. Below mentioned is the average maintenance cost of Solar panels on grid system.

11kw – 10 kWRs. 2,000 / kW – Rs. 3,000 / kW
211kW – 30kWRs. 1,500 / kW – Rs. 2,000 / kW
330kW – 50kWRs. 1,000 / kW – Rs. 1,500 / kW

So here is a quick go to checklist that can make your task easy :-

  • Solar panels are spotless and free of defects and debris

  • No signs of corrosion or deterioration

  • The vents are clean

  • No visible defects in the switches
