Solar Panels

Types of solar panels:

There are different types of solar panels serving different kinds of needs and purposes of the user. The Location plays a very vital role while making a choice for a particular kind of solar panel for installation.

There are several factors which affect the type of solar panels.

  1. Panel Mounting: On basis of the mounting system of the solar panels, it can be divided into two broad categories:
  • Roof mounting: The solar row of the photovoltaic system are set up on a rooftop. The setting basically has a gap of a few inches running parallel to the surface of the roof. The roof mounting is done by designing the roof by installing support brackets for the panels before the final set up is done. It requires the practice of setting up strong support brackets per hundred watts of panels for proper installation of the roof-mounted solar panels.
  • Ground mounting: The system of ground mounting of Photovoltaic cells provides a larger and more utility-scale of PV power stations. There are further subdivisions in it, which include pole mounts, ballasted footing mounts, and foundation mounts.
  1. Panel Efficiency: On basis of the efficiency provided by the solar panels, it can be divided into further subdivisions:
  • First generation Solar Panels: These solar panels are most common and well suited for sale in conventional surroundings like areas of Delhi NCR. It can be further divided into:

Monocrystalline Solar Panels: These panels own a uniform and dark look with neat round edges. They are considered as the panels owning most efficient energy rate due to the usage of pure silicon. Monocrystalline Solar panels own a very high rate of power output. Other than its power rate, it is also less space consuming and ensures a long life. Moreover, these Monocrystalline Solar panels do not tend to get much affected due to high temperatures which make them more popular compared to the polycrystalline panels. However, these solar panels can be used in areas with good availability of space like your home in Gurgaon area. Moreover, it is very pocket-friendly too.

Polycrystalline Solar Panels: These solar panels can be easily identified because it has neatly cut square panels with no separate angle cuts. It owns a blue speckled look because it is made up of melting raw silicon. It is more fast and cheap in comparison to the Monocrystalline Solar Panels. They tend to get affected by hot temperatures as well. However, there is not much difference between the Monocrystalline and polycrystalline solar panels because their power outputs are nearly same.

  • The second generation Solar Panels: These solar panels are on sale in India and are used at photovoltaic power stations or found in integration with buildings or other smaller solar-based power systems.

Thin Film Solar Cells:  As these panels are made by placing films of one or more photovoltaic material over a substrate, they are quite cheaper. These panels are easy to produce and are also pocket-friendly. These panels have a wide range of application alternatives and are also less affected by the higher temperature ranges. However, the major drawback of these panels is their huge space capturing tendency. This makes it quite unsuitable for installation in the residential areas. These panels also hold a very short warranty period in comparison to the mono and polycrystalline solar panels

  • The third generation Solar Panels: These panels constitute the technology of ‘thin film’. However, most of the third generation panels are either in research or in the development These cells make use of organic as well as inorganic substances. As it is still in its development phase, these solar panels are not in many sales in India.

Biohybrid Solar Cells: These solar cells are still in their research phase. The idea which is used for the technology is taking the benefit of photosystem 1 and then emulating the process of natural photosynthesis. Many materials are used in its manufacture which is much similar to the traditional methods. Multiple layers are combined together which results in easy change of chemical to electrical energy.

Concentrated PV Cells: This is basically a multi-junction type of solar panels with an energy efficient rate of 41%. The manufacture of these cells includes usage of a variety of materials like the curved mirror surface, the lenses, and even the cooling systems. It helps to increase the efficiency of the solar cells and allows the cells to capture the sun rays properly. However, these panels work in the best manner only if they face the sun at a proper angle. Another benefit of these panels is the usage of solar trackers. These trackers are present inside the solar panel and it helps to follow the sun to capture its heat. These solar panels can serve a huge benefit for home in Gurgaon and Delhi NCR areas because it is renewable and cost-effective.

  1. Panel Construction: On basis of the construction method of the panels, it can be subdivided into following categories:

Cadmium Telluride Solar Cells: These solar cells make use of Cadmium Telluride in its photovoltaic technique resulting in the making of solar cells at very low cost. These solar panels help in keeping the carbon footprint at a lower level as it owns a short energy payback period. However, the only drawback of these cells is that these cells make use of Cadmium Telluride which is toxic and so these solar panels are not in much demand for sale in India.

  • Amorphous Silicon Solar Panels: These solar panels make use of the triple-layered technology. This technology is considered as the best thin film variety. These cells are most commonly seen in pocket calculators. These cells are used widely due to its low cost. However, these are very less effective compared to the crystalline and silicon ones.
  1. Panel Diodes: A diode is basically a semiconductor material of silicon in which two terminals are attached. On basis of the panel diodes, there are two subdivisions of solar panels:

Blocking diode: It is a simple setup in which two panels are joined by series. It is quite impactful in charging a battery using the solar panels. The blocking diodes are usually involved in the construction of the solar panels so that no requirement arises for the blocking diodes anymore after the installation process.

By-pass diode: In case the solar panel gets shades over an area which results in the blocking of regular products of energy, bypass diode plays an important role. It works when MPPT Controller or String Inverter is involved in the panels which are connected in a series circuit for the production of electrical energy.
