How Are Residential Solar Panels Made And How Do They Work?

As we enter sweltering, sun-drenched summer in Dubai, it’s easy to imagine the power of the sun. Installing a home solar power system in summer adds more productivity as there are increased sunny hours and more intensity in sunlight.

In recent years, solar panels have become more accessible due to manufacturing efficiencies. Solar systems are now visible on the commercial properties and rooftops of many residential homes. According to the Solar Energy Industry Association (SEIA), there is a massive growth in the solar industry with a 50% of annual growth rate in the last decade. But why do they have so much demand? What are they made of? And how are they made of? All these questions might be popping up in your mind. Do not worry we are here with you to answer everything about solar panels.

1. Why Do Solar Panels Have So Much Demand?

Affordable prices have made solar panels competitive in the market. In addition to the prices, solar panels save electricity and even contribute as a green option for the ecosystem.

2. What Are Solar Panels Made Up Of?

When you look at residential solar panel systems in Dubai, they simply look like a single compressive block but actually, they are made of bevy materials and chemical components that play a crucial role in converting solar light into usable electrical energy.

The crystalline silicon wafers are used as the main component material in the solar PV panels because silicon is used to create semiconductors for about 95% of solar panels on the market today. And the remaining 5% is used for experimenting and developing technologies like organic photovoltaic cells.

The semiconductors infused in solar panels generate electricity upon getting interacted with the sunlight. The electrons present in the silicon get knocked loose and generates electricity, this entire process is called the photovoltaic effect.

Of course, residential solar power system does not just need silicon to power your home with electricity but they also need components like plastic, metal, wiring, and glass. The solar panels are covered with a layer of glass and anti-reflective coating on them to protect the silicon cells and heave the sunlight into the panels. The whole infrastructure is supported by a polymer/plastic frame for installing on the ground mount or rooftop solar panels.

Solar systems come in various designs, styles, and sub-components. The most common types of solar panels are monocrystalline, polycrystalline, and thin-film solar panels.

  • Monocrystalline Solar Panels:
  • The monocrystalline solar panels are made up of a single silicon crystal and they are the most expensive and efficient solar panels.

  • Polycrystalline Solar Panels:
  • The polycrystalline solar cells are made up of multiple silicon crystals melded together. These are not much efficient compared to monocrystalline panels but are more budget-friendly when you wish to opt for a less expensive solar system.

  • Thin-Film Solar Panels:
  • These Thin-film solar cells are made from amorphous silicon which makes them the most flexible solar panels but is least efficient.

3. How Are Residential Solar Systems In Dubai Made?

The manufacturing process of solar panels has become quite streamlined, and standard and keeps up with the growing global demand for solar systems.

Solar manufacturing begins with the creation of solar cells. This process involves melting the silicon material and mixing it with the supportive elements. Then the sheets of material are cut and turned into component cells. This entails mass production, laser cutting, and expedite manufacturing. The cells are then protected with a layer of glass or plastic.

Once the solar cells are created they are connected together into the right size, shape, and configuration. The manufacturers solder them to the base of the solar panel made with a conductive metal. The base houses of the solar cells transfer the electricity to a single location whether they are being sent into a building or a commercial property or a local power grid.

The solar module is then connected to an outer polymer frame that holds the panel and then the solar panels insulate the electrical components and covers everything with a protective layer of glass. Finally, the manufacturers box the panels and send them to the installers.

4. How Do Solar Panels Work?

Before knowing the science behind converting particles of light from the sun into energy you need to know about the polarizing conductors. The polarizing conductor is nothing but a metal conductor such as boron that forms two types of silicone materials when added to the silicon wafers.

    1. N-Type Silicone: This silicone lies on the surface of the solar panel.

    2. P-Type Silicone: This silicone lies below the N-type silicon.

We have studied in physics that positive and negative energy poles attract each other and negative and negative or positive and positive poles repel each other. Similarly, treating N-type silicon and P-type silicone creates a power imbalance in the solar panel as a result the N-type and P-type silicon wafers fill the void in each other.

The N-type silicon is a pure form that has one extra electron and the P-type silicone has one less electron with impurities from an infusion of boron. When the sunlight falls over the solar panels the electrons begin to move in and around attempting to fix the shortfalls, as a result, the photons knock electrons and generate electricity.

The electricity collected from the solar power systems is then converted from direct current to alternate current with the help of an inverter and then the electricity feeds back into the property’s electricity system.

This is the entire process involved with the manufacturing and installation of solar panels. If you are looking for solar panels for home installation you can count on us! Wattz is one of the leading solar panel installers in UAE providing residential and commercial solar panels.
