How Are Solar Panels Made and Installed?

Solar panel units come in different shapes, sizes, and power outputs. Each panel features solar cells, silicon, metal, and glass. These components are arranged together to form a functional solar panel that can generate renewable energy from the sun. Here is more information about how solar panels are made and installed by a solar company:

Making Solar Panels

A solar company may offer various solar panel types, but they are all made of basic components like solar photovoltaic (PV) cells, silicon or polysilicon, glass, and metal. The solar PV cells help to convert sunlight into energy. Solar cells are often protected by a layer of transparent glass that filters the sunlight through them. An electric current is generated when solar silicon dioxide cells are exposed to sunlight. Solar panels produce DC electric current, which is converted into AC using an inverter.

Multiple solar cells are connected using wiring to generate more electricity. The wiring also helps to transfer the electric current from the solar cells to the inverter. Solar panel wires soldere to the solar cells and assembled between the protective glass and a back sheet. The panel is then held together with a sturdy metal frame.

Building the Silicon Cells

The first step in making solar panels is building the p-type or n-type solar silicon cells. P-type cells are positively charged, while n-type cells negatively charged. Most manufacturers use boron for the bottom layer and phosphorus for the top layer of p-type cells. The n-type cells feature the opposite assembly, with phosphorus at the bottom and boron at the top. Solar cells feature crystalline silicon melted and mixed with boron or gallium.

Phosphorus and boron or gallium add to the crystalline silicon to give it electrical capacity. The silicon is cut into thin sheets and given an anti-reflective coating to absorb the sunlight. Thin lines curved into the cells to move the created electrical current within the solar cell. When sunlight hits the solar cells, the protons absorb while the electrons drift to produce energy, turning the solar cells into semiconductors.

Enclosing the Solar Cells

The solar silicon cells are the main component of a solar panel. Once the cells form, a solar company can solder them into a meeting. The next step is to install a back sheet onto the board to protect the underside of the cells. Manufacturers then add a layer of transparent glass to the front to allow light to filter through. Both layers help protect the solar cells from weather elements and damage.

The last step of enclosing the cells involves sealing a metal frame around the multi-layered panel. Manufacturers then add a junction box to the frame to house the panel’s electrical wires. Solar panel manufacturers evaluate the final quality and strength of the panels’ components. Panels that have gone through quality testing are ready to be shipped and installed on residential and commercial properties.

Installing Solar Panels

The installation team can help you identify the best location to set up the solar panel. The panels should install in an area with optimal sunlight for efficient energy production, like a rooftop or open field. Your solar company will install the panels slightly raised from the ground or roof surface for thermal efficiency. Installers will then test whether the solar power system is working as anticipated.

The boards also test for resilience against weather elements. Some solar panels install permanently on your property. Others are mobile, so you can take them inside your house once the sun sets.
