Solar cell technology is always evolving and improving. PERC solar cells are a relatively new innovation in the solar industry – in this article, we’ll dive into what PERC solar cells are and how are they impacting solar panel technology.

Monocrystalline Solar Panels for Commercial and Utility-scale Projects

With a technology that combines rear wafer surface passivation and local rear contacts to maximize light capture, monocrystalline solar panels are paving the way for dramatically increased PV system efficiency.

Monocrystalline solar panels are manufactured from single silicon crystal. They have high efficiency, better low light performance and long life span owing to the fact that they are made from high quality silicon crystals. Polycrystalline (Poly) Modules, as the name implies, are made from melting multiple silicon crystals. They are simple to manufacture, cost-effective and produces less wastage.

However, rapid changes in cell manufacturing processes are beginning to narrow this cost advantage that poly modules enjoyed over their mono counter parts.

Important Aspects:-

1. Better flexibility – Provides the end-users with more tilt and placement options without sacrificing efficiency. Convenient for residential consumers with space restrictions on roofs.
2. Higher energy density– Lower levelized energy cost leads to lower payback periods.

Advantages:-

•  Efficiency-  Monocrystalline solar panels are able to convert the highest amount of solar energy into electricity of any type of flat solar panel. Consequently, if your goal is to produce the maximum electricity from a specific area (e.g., on a roof), this panel should certainly be considered. Consequently, Monocrystalline panels are a great choice for urban settings or where space is limited. As a developer of PV rooftop installations, buying or leasing roof space consumes a significant cost of the whole project. You would want to be able to produce as much electricity you can from this valuable resource.
  

• Greater Heat Resistance-
  Like the other types of solar panels, monocrystalline solar panels suffer a reduction in output once the temperature from the sunlight reaches around fifty degrees Celsius or hundred and fifteen degrees Fahrenheit.  Reduction in efficiency between twelve and fifteen percent can be expected.  This loss of efficiency is lower than what is typically experienced by owners of PV panels made from polycrystalline cells.

• More Electricity-
  They produce more electricity per sqm of installed panels, thereby improving your cash flow. It could be from either a reduction in your electrical bills, or from the sale of the electricity or in some areas, both. For those who are “going green” and are concerned about the environmental impact of solar panels, monocrystalline panels reduce the amount of electricity needed from local power plants, thus, reducing the dependence on fossil fuels. The greater benefit is a reduction in the use of limited fuel sources and greenhouse gases being pumped into the environment.
