An Informative Guide on Mono Perc Solar Panels: Price, Pros, and Cons

Paving the way for a dramatic increase in the efficiency of photovoltaic systems, mono perc solar panels are gaining popularity in recent times. 

The technology behind a mono perc solar panel is an ideal combination of rear wafer surface passivation and local rear contacts, maximising light capture. 

These panels meet the needs of commercial and utility customers, helping solar power systems of all sizes unlock value and accelerate energy production. 

The upcoming sections will provide insights into the working of a mono perc solar panel, mono perc solar panel price, the pros and cons of purchasing a mono perc solar panel, and more. 

How does a Mono Perc Solar Panel Work? 

PERC is the abbreviation of Passivated Emitter and Rear Cell. It is a modern technology, largely used to enhance the efficiency of solar modules. 

Adding a passivated layer in the rear of the cell brings about a change in the working of the solar panels.  

In standard modules, the sunlight that falls on the surface is either reflected, passed through the surface, or absorbed. Contrastingly, in the case of a solar panel mono perc, the light passed through the perc solar cell can be used again. 

The passivated layer present on the rear side of the solar panel is capable of reflecting the photons; thereby, increasing the amount of light absorbed by the module. It ensures a higher energy production.

The Efficiency of a Mono Perc Solar Panel

A mono perc solar panel is one of the most innovative devices for capturing solar energy. The latest technology in designing these solar panels boosts their energy efficiency between 22% to 25%. 

They are suitable for harnessing energy even in low light or cloudy weather and justify the high capital expenditure. Moreover, fewer numbers of mono perc solar panels can achieve the required energy production. 

The following points elucidate the efficiency of a mono perc solar panel:

  • Exceptional performance under high temperature and low-light conditions.
  • Provides enhanced energy density per square foot than conventional panels. 
  • The reflection of unabsorbed light back into the solar cell increases light absorption.
  • The anti-reflective coating further enhances efficiency and captures more light.

Pros and Cons of Buying A Mono Perc Solar Panel

The perks of buying a mono perc solar panel outnumber the demerits. However, you must go through both before making a choice. 


  • Cost-Effective: Although mono perc panel costs are high, the enhanced efficiency justifies the capital expenditure. It also decreases the number of solar panels needed and installation costs. 
  • Highly Flexible: Mono perc solar panels come with better flexibility as the extra layers make them better equipped for low-light conditions and high temperatures. They generate power early during the day and continue to perform late till the evening. 
  • Minimal Modifications Required: They require minimum modifications from manufacturing to installation. 
  • Slow power degradation rate: They degrade much more slowly than traditional modules. Thus, they generate more electricity in their lifespan. They have a sustenance capability of more than 25 years.
  • Higher energy density: Low energy cost with lower payback periods.


  • High purchasing cost: The cost of mono perc solar panels is high compared to other traditional solar panels. 
  • Performance: The performance can slightly decline due to increasing temperature.

Mono Perc Solar Panels Price

The price of mono perc solar panels is high in comparison to mono solar panel price. The following table enumerates the average mono perc solar panel price range. 

The prices can vary ± 10% -12% based on the brand, location, promotions, and availability. 

Solar Panel Model (Watt)Selling PricePrice Per Watt
165 W Mono perc solar panelRs. 4500 -5000Rs. 27-30
200 W Mono perc solar panelRs. 5500- 6000Rs. 28-30
375 W Mono perc solar panelRs. 10,000-10,500Rs. 26-28
400 W Mono perc solar panelRs. 11000-11500Rs. 27- 28

Subsidies on Mono Perc Solar Panel

The government encourages the adoption of renewable solar energy by offering a subsidy on solar panels. It financially supports the installation of solar power systems in residential homes. 

Consumers must note that the solar subsidy is only available on DCR panels for residential use. 

In other words, there’s no subsidy available for mono perc solar panels since these panels are not entirely manufactured in India. 

Maintenance of a Mono Perc Solar Panel

Consider the following pointers to take good care of your mono perc solar panels:

  • While installing the panels, ensure that you set the right orientation. Install them in shade-free places. 
  • Opt for proper periodic cleaning.⁣
  • Adopt measures to prevent overheating during hot sunny days.⁣
  • Use a solar concentrator to maximise the output.


Efficiency is a key parameter to consider when selecting a solar panel.⁣ On average, a mono perc solar panel comes with a 22%-25% efficiency boost promise. 

Opting for a mono perc solar panel is a cost-effective option and these panels take up less space. 

The innumerable benefits that easily compensate for the high purchase cost are the main contributing factors to the skyrocketing popularity of mono perc solar panels.


Q1. Which one is better: Mono or Mono perc solar panel?

When taking into consideration the overall energy production and space requirement, mono-perc solar panels are better than standard mono panels. 

Q2. What is a bifacial mono perc solar panel?

Mono perc bifacial panels are formed by using the perc technology with bifacial modules. Bifacial solar panels have two sides of solar cells collecting light. 

Q3. Are bifacial mono perc solar panels suitable for residential purposes?

Bifacial solar panels are more suitable for commercial and utility solar developers rather than residential rooftop projects. 

Also, these panels need space behind them so the reflected light can reach the panel. Therefore, it isn’t appropriate to install them on rooftops.
