Are monocrystalline or polycrystalline solar panels better for a rooftop solar system? This is a question that every solar super-optimizer asks. Solar panels can increase the value of your home while also lowering your monthly utility cost. However, because they might be an expensive upfront purchase, you’ll want to be sure you get the most bang for your money. What are the differences in performance and cost between mono and poly solar panels, and which is better for your needs?

They are conductive and help in generating an efficient amount of electricity. It can be utilised in various forms for commercial and residential purposes.

You will get to know about the mono vs poly solar panels in the article.

Solar panels are categorised into two different categories:

  1. Monocrystalline
  2. polycrystalline

What Do Monocrystalline and Polycrystalline Solar Panels Have in Common?

Solar panels gather solar energy and convert it to electricity using solar cells (also known as photovoltaic cells). Raw silicon wafers are moulded into a consistent size to make solar cells.

Solar panels come in a variety of shapes and sizes, but they all have the same purpose: to capture solar energy and transform it into power. The true distinction is in the technology employed to execute that function: the type of silicon used in the solar cell.

  • Monocrystalline solar panels

The monocrystalline solar panels have the appearance of black coloured PV cells with round edges. It has a high level of conversion efficient cells. You can choose to install the monocrystalline panels in a limited space. It can produce more kilowatts of electricity per square foot. The lifespan of these solar panels is about 25 – 40 years.

You will find these solar panels more expensive because of their complex making procedure. It can also provide you with the benefit of a major return on investment in the longer term.

Performance – If you measure the performance level of the monocrystalline solar panels then it ranges from 17% to 22%. Its high efficiency makes it suitable for your commercial space. You can fix it in the limited space with more electricity production. The solar cells are made from a single silicon crystal that allows the electrons to flow easily through the cell. It makes the cell more conductive and efficient.

  • Polycrystalline solar panels

You will find the PV cells of the polycrystalline solar panels appear in blue with straight edges. It is less efficient and requires more panels to generate a good amount of electricity. The lifespan of polycrystalline solar panels is about 20 – 35 years.

Polycrystalline solar panels are less expensive and affordable because of their easy manufacturing process. It is easily affected by the high temperature and reduces its efficiency on hotter days.

Performance – The performance rating of these solar panels ranges from 15% to 17%. It is less efficient because of multiple silicon cells that create hindrance in the easy flow of the electrons. You can use it for residential purposes as you will require electricity according to the need at home. Your rooftop has more space to install polycrystalline solar panels.

It is quite essential to know the exact performance and effectiveness of the solar panels. The monocrystalline vs polycrystalline solar panels will help you differentiate the qualities. It allows you to make more suitable and correct decisions.

  • Suitable solar panel for commercial use

The commercial space uses high consumption devices such as computers, laptops and printers. It requires a continuous flow of high amounts of electricity for the whole day. You can install monocrystalline solar panels for commercial use. It can be easily installed in the limited space for your official use. The commercial solar panels installation will help you to reduce the upfront cost of the electricity bills.


You can easily save more money on electricity consumption bills through one-time installation. It is the best usage of natural energy resources and is eco-friendly.


  • Monocrystalline solar panels are more durable and efficient.
  • They are low-temperature coefficients that ensure their consistency.
  • It can be installed in less available commercial space.

The monocrystalline solar panels also have high power capacity ratings. Its output and production are about 320 watts and that can go around 375 watts and higher. On the other hand, polycrystalline solar panels have a power rating of about 240 watts that goes around 300 watts. The efficiency and power capacity compels the installation of monocrystalline panels in commercial space.
