Solar Panels For Residential Use : Definition, Types, And Cost

Introduction Solar Panel For Residential Use

Solar panels for residential use over the past few years, India’s use of solar electricity has increased. The distinct mechanism of these panels is credit with the rise in demand. Data indicates that since 2021, solar panel adoption for residences, businesses, and offices has increased dramatically. By 2027, the market size for the solar sector is project to increase by about 34%. The data points to a growing public interest in microgrid deployment and renewable energy sources.

Why Should Homeowners Install Solar Panels?

Installing solar panels on the roof of your house allows you to harness solar energy for household needs. Solar panels convert solar energy, which comes from the sun, into alternating current (AC). Your house or other locations can be safely power by this energy.

Homes with rooftop solar panels will use less electricity overall. You may therefore regulate and restrict how much energy and electricity you use. Furthermore, solar panels made by reputable brands are robust. As a result, there is a reduced likelihood of a service outage.


Solar Panel For Residential Use : Mechanism

Electricity is produce from solar energy using all kinds of solar panels. Every panel is compose of multiple separate solar cells. Most often use solar panels have 72 cells, measuring 2 metres by 1 meter, and 60 cells, measuring 1.6 metres by 1 meter.

A combination of silicon, boron, and phosphorus makes up the solar cells. Similar to this, sunlight contains several energy sources refer to as “photons.” Photons striking solar panel surfaces remove electrons from silicon, creating a direct electric current that continues through silver busbars and fingers. Consequently, solar panels are use to generate energy. The process is known as the photovoltaic effect.


Solar Panel For Residential Use  : Benefits Of Installing

There are several benefits to using solar energy at home. Some of them are mention below:

  • Solar power is environmentally friendly and clean. As a result, when energy is generate, it produces zero pollution.
  • Because it doesn’t rely on any other energy source, natural energy sources are under less stress. Both the environment and you would benefit from having solar panels install in your house.
  • Solar power panels require very little upkeep. All that needs to be done is clean them twice a year. Nonetheless, experts should handle the cleaning procedure.
  • Solar electricity is a safer option than air conditioning for maintenance and repairs.
  • It may be use anywhere in the world and is an endless source of energy.
  • Your electricity costs will be significantly reduce if you use solar power.
  • It is even capable of delivering electricity to places without power. Clean water for home and business use, as well as for everyday tasks, can be obtain from solar energy.


Solar Panel For Residential Use : Residential Solar Panel Types And Their Features

In India, there are primarily four kinds of solar panels for residential use. Homes, industries, offices, and other facilities frequently employ these.

  1. Monocrystalline solar panels
  2. Polycrystalline solar panel
  3. Passivated Emitter and Rear Contact cells (PERC) solar panel
  4. Thin-film solar panels


Monocrystalline Solar Energy

Single-crystal solar panels are another name for monocrystalline solar panels. They are create using pure silicon crystals that are divide into several wafers to create cells. After that, these wafers are slice into octagons, which gives them their distinct appearance and consistent colour. They are often blue or black in colour because they are construct entirely of silicon.

A well-known feature of monocrystalline solar panels is their half-cut cell design. Square-cut cells are divide in half in this feature, providing twice as many cells. There is a certain series of cells in the panel’s top and bottom halves. As a result, these panels have the ability to generate electricity even in the event that one half of them is shade. These are quite effective when the solar panel is partially shade from the sun. These are the solar panels that are most frequently use in residences.

Features Of Monocrystalline Solar Panels

  • Because single silicon crystals make up monocrystalline solar panels, there is more room for electrons to travel, which results in a higher kW/hour of power being produce. As a result, adding these solar panels to your house will enable a larger electrical backup.
  • They outperform other solar panels in terms of heat resistance. This indicates that heat has no effect on their ability to produce electricity; in fact, higher temperatures cause them to operate more efficiently.
  • These panels often cost more because of the more intricate production process.


Polycrystalline Solar Panels

Polycrystalline silicon panels are made up of many silicon crystals. Melting and pouring silicon pieces into moulds is the process require to create a polycrystalline panel. After that, these crystals are left to cool. After they are finish, these are cut into thin wafers and put together to create the polycrystalline panels. These are also refer to as multi-crystalline panels.

Features Of Polycrystalline Solar Panels

  • Polycrystalline solar panels are less efficient than monocrystalline ones.
  • This is a result of the panels’ multiple silicon crystal construction, which limits electron mobility due to spatial constraints.
  • Polycrystalline panels are easily recognise by their bright blue, straight borders, and square-shaped cells.
  • Because there is less silicon waste during the development process and a simpler production process, these are less expensive than monocrystalline panels.


Passivated Emitter And Rear Contact Cells (PERC) Solar Panels

Perc. Rear cells are another name for solar panels. The panels are construct with cutting-edge technology; to fully utilise the sunlight that passes through the solar cells, an extra layer is add to their backs. Conventional solar panels allow some light to get through while also absorbing some of it. On the other hand, complete energy retention is guarantee by the extra layer of PERC panels. PERC panels are, hence, more efficient. In order to achieve even more efficiency, producers have recently begun merging PERC technology with monocrystalline cells.

In order to achieve even more efficiency, producers have recently begun merging PERC technology with monocrystalline cells. These mono-PERC panels are usually use in commercial settings and produce the highest power output.

Feature Of PERC Solar Panels

  • Because PERC solar panels absorb sunlight better than conventional panels, they have a higher efficiency.
  • The extra layer at the panel’s back captures and holds onto sunlight for complete absorption.


Thin-Film Solar Panels

Solar panels that are thin-film differ from those that are monocrystalline and polycrystalline. These solar panels are made from photovoltaic materials, which include copper, indium gallium selenide, cadmium telluride, and amorphous silicon. It is lighter and simpler to install since these components are place on a solid surface like plastic, glass, or metal.

Thin-film solar panels are of different categories, such as –

  • Amorphous silicon (a-Si): The silicon in these panels lacks structure at the molecular level and is amorphous in nature.
  • Cadmium telluride (CdTe): This material has the least carbon footprint, but it is poisonous and may eventually affect the ecosystem.
  • Copper, indium, gallium, and selenium (CIGS): When making GICS panels, a thin layer of indium, copper, selenium, and gallium is apply to a glass or plastic sheet. They are the most efficient thin-film panels available due to their unique technique and superior absorption capabilities.

Features Of Thin-Film Solar Panels

  • Thin-film solar panels are easier to install, lighter, and more flexible than regular solar panels.
  • The efficiency of silicon crystalline solar panels surpasses that of thin-film solar panels. But these are less carbon-foot printing and more reasonably priced.
  • Areas with expansive rooftops or spaces are appropriate for the panels. In India, installing solar panels calls for customised design. The roof, structure, shading, specs, and utility will all affect which type of solar panel is best for your home.
