Here Are The Most Efficient Types Of Solar Panels | Energy Hamd

    Installing solar panels is an effective way to conserve energy and reduce energy bills. However, it is important to know the different manufactures of solar panels in order to choose the most efficient solar panels for your commercial or residential installation.

    1. How to determine the efficiency of solar panels

    The efficiency of solar panels is determined by the amount of sunlight reflected off the surface of the panels, which is then converted into electrical or thermal energy. Previously, the average efficiency of solar panels was about 15%, but thanks to advances in photovoltaic technology, the efficiency now exceeds 20%.

    There are two factors that go into determining the efficiency of a solar panel: the efficiency of the photovoltaic cells (PV) and the overall efficiency of the panels. The efficiency of the photovoltaic cells results from the design of the cells and the type of silicon, while the arrangement and composition of the cells as well as the size of the panel form the basis of the overall panel efficiency. The overall panel efficiency is determined by the maximum rated power under standard test conditions divided by the total panel area (in metres).

    A number of factors can affect efficiency, such as temperature, cell type and illumination level, which is how quickly sunlight affects the panels. The color of the back sheet that protects the panels can also affect efficiency. For example, while black may appear more attractive to a protective black sheet, the color absorbs more heat. This results in higher temperatures and therefore lower overall conversion efficiency, so other colors such as dark blue, green, or even patterns may be a better choice for your solar panels.

    2. The main types of solar panels

    There are three types of solar panels that are often used in commercial/industrial or residential/built-up facilities: monocrystalline, polycrystalline, and thin film. Below is a brief explanation of each, along with the most useful applications of them:

        Monocrystalline: Best in Efficiency

    Monocrystalline solar panels are often touted as the most efficient option, and therefore best when installed for larger power systems in commercial and residential properties. However, the sizes of the panels vary; Therefore, monocrystalline can also be used in smaller formulations.


  • Made of silicone with a high purity index which increases its efficiency from 15% to 22%
  • It does not require as much space as crystal and thin panels
  • Monocrystalline panels can last up to 25 years due to the stable and inert properties of silicone


  • The price is high due to its complex construction
  • It is not a good choice for cold climates, where snowfall can damage solar cells and cause the system to fail.

The best brands of monocrystalline solar panels: SunPower, LG, Panasonic

        Polycrystalline: the best value for money

    Polycrystalline solar panels consist of several pure silicon crystals that are fused together. However, more crystals is not always better. Polycrystalline panels are less efficient than monocrystalline panels. However, they are manufactured in a variety of power settings ranging from 5W to 250W and above, making them a good choice for both small and large sized installations.


  • Its creation process is simpler, so it is cheaper than monocrystalline
  • Less waste after the melting process, making it better for the environment
  • Durable and long lasting, just like monocrystalline solar panels, so it's a good choice for budget-conscious homeowners.


  • Lower efficiency (13 to 17%) because the silicone used in their manufacture is less pure.
  • Takes up more space to produce the same level of energy as monocrystalline cells.
  • Best Polycrystalline PV Solar Panel Brands: TrinaSolar and YingliSolar

        Thin film: the best for transporting

    Although they are light and easy to move, thin-film photovoltaic cells are the least efficient type of solar panel. Use them only for an installation that will not need to produce too much energy.


  • Easier and cheaper to produce
  • Excellent for solar transport applications, such as panels installed on bus roofs and refrigeration for refrigerated trucks


  • Not a good choice for roofs, as they require a large space to satisfy the energy requirement
  • Lower yield.
  • Best Thin Film Solar Panel Brands: Stion and Solopower

     3. What to consider when purchasing solar panels

  • Cost

    Solar panels can be expensive to start with, which is why many homeowners don't make the decision to go without solar power. The Center for Sustainable Energy reports that installation can cost, on average, between $15,000 and $25,000. Polycrystalline solar panels are the most cost-effective option in solar panel installations, but it depends on the type of panels and the number required for installation.

    While your initial investment in solar panels may pay off over the years, it may take longer to get your money back depending on a number of factors including energy consumption and weather conditions. ; The latter can affect the functionality of the solar panels.

  • Location

Not surprisingly, solar energy is more efficient in places where there is more sun exposure. Residential and commercial buildings in Southern California, for example, are likely to reap more benefits from solar energy than those in the cloudy Pacific Northwest. However, even places that are not in sunshine can benefit from solar energy, because cooler temperatures will cause the panels to generate more energy.

  • Energy consumption

    If your energy bills are high, it makes sense to install solar panels to cut costs and recoup the initial investment over time. However, if your energy use is minimal, installing solar panels may not be worth it. It is also important to note that the maximum efficiency is achieved only under optimal conditions and only for the beginning of the service life of the board. As solar panels age and are exposed to the elements, they will begin to operate less efficiently.
