Which is the Most Efficient Solar Panel?

Installing solar panels is a great way to conserve energy and cut your utility bills. Nevertheless, it is essential to understand the fabrication, construction, and differences in solar panels in order to select the most efficient ones either for your residential or commercial installation. In order to decide which solar panel is the most efficient one, we need to know how exactly the efficiency of a solar panel is determined. Let’s look into the subject matter!

Determination of the Efficiency of a Solar Panel

The efficiency of a solar panel corresponds to the amount of light reflected by its surface, which is then transformed into thermal or electrical energy. The following two factors play major role in determining the efficiency of a solar panel:

Photovoltaic cell efficiency 

Cell design and the type of silicone used define photovoltaic cell efficiency.

Total Panel efficiency

The fundamentals of total panel efficiency are the cell layout, configuration, and the panel size. It is determined by the maximum power rating under test conditions that are standardised, divided by the total area of the solar panel.

Other Factors Affecting the Efficiency of a Solar Panel

There are other factors which influence the efficiency of a solar panel. These include irradiance level, temperature, and cell type. Irradiance level defines the rate at which sunlight hits the solar panel. In addition to these factors, the colour of the back sheet that protects the panel also influences the efficiency. For instance, black colour absorbs more heat and thus increases the temperature. This increased temperature results in lowering the conversion efficiency. Therefore, it is advisable to use white or other colours such as green or blue, etc.

The Most Efficient Types of Solar Panels

Following types of solar panels are usually preferred for residential and commercial purposes:

  • Monocrystalline Solar Panels
  • Polycrystalline Solar Panels
  • Thin Film Solar Panels

Among all of these, Monocrystalline is considered the best for efficiency.

Monocrystalline Solar Panels

These are generally considered the best solar panels available on the market, therefore, these are being installed on both residential and commercial properties. Panel size of this type may vary, hence they can be used in medium to small installations as well. Let’s look into the salient features of the best touted solar panels!

  • They are made out of silicon and have a high purity rating. It boosts their efficiency to a great degree, usually in the range of 15 percent to 20 percent.
  • They can last for longer periods of time due to inert and stable features of silicon. This property makes them the most cost-efficient among other different types of solar panels.
  • They require less space as compared to Polycrystalline and Thin Film solar panels.

However, Monocrystalline solar panels cost a fair deal because of their complex construction.

Final Words

The efficiency of a solar panel is dependent on certain factors as mentioned above. However, there are some panel types that are more efficient than others and are preferred by both residential and commercial consumers.
