Home solar panels have been used to power the home for many years. It's a cheaper option compared to conventional electricity that is widely produced and that's the best part; it is a renewable energy source.

However, despite the many benefits of using solar energy, the adoption rate is still slow and this comes down to resistance from other energy producers who are well aware of what will happen if solar energy is adopted.

We are going to explore solar panels and solar mounting structure , starting with what they are, how they work, their installations, the benefits they bring, the limitations and any other issues affecting their implementation in today's world.

If you have always been curious about solar panels for your home, then you have come to the right place.

CONSTRUCTION AND OPERATION OF SOLAR PANELS

Solar energy is energy obtained directly from the sun. It is being used in a solar panel design that now collects solar radiation for use in a variety of applications in the home, both heavy and light.

The solar energy industry has grown rapidly over the past 20 years but has not reached its peak due to access issues. But on earth, solar energy is one of the cheapest forms of electricity, with only the initial cost being higher, and it is also gradually decreasing. 

How Solar Panels are Made

Solar panels are made up of specific parts that work together to ensure that the sun's radiation is captured and converted into energy.

Broadly explained by a solar structure manufacturer, the average home solar panel has six main components that are essential for its smooth operation. They include the following.

Solar photovoltaic cells

Better known as Solar PV The cell is the part that converts direct sunlight into direct current electrical energy. How a solar panel works depends on the type and nature of the PV cell.

The main component of the PV Cell is silicon, and it comes in two types, which can be single-crystal or poly-crystal. 

Monocrystalline are more efficient and cost the most compared to their counterparts, which have the lowest efficiency and cheapest maintenance; Between the two, there is one derivative called single crystal cells, which has the efficiency of single crystal cells, but is almost as cheap as polycrystalline cells.

PV Base The cells are lined with plates about 0.1 mm thick, which for greater efficiency consist of both positive and negative silicon ions.

This part of the solar panel comes in different sizes and shapes depending on the intended use, but the bottom line is that it is one of the most important parts, converting direct sunlight into electrical energy, which is then used for all kinds of work.

Glass

PV cells need to be protected from physical damage, and at the same time they must be fully exposed to the sun.

So how do you take care of it? In the form of tempered glass that provides both the necessary protection and gives the cells full access to sunlight without filtering anything.

The glass is mainly made of about 3mm thick tempered glass with mechanical strength, making it an ideal protective layer for solar panel.

It is the first line of defense that protects every fragile part inside from flying debris, which is common as corners are exposed to the elements all day long.

International safety standards state that normal solar glass should be able to withstand 1-inch diameter hail traveling at about 60 miles per hour.

Anything bigger and faster than this is likely to do significant damage. But the likelihood of this level of hail occurring in areas receiving sunlight all day long is very low.

For greater efficiency, a new form of glass is being used around the world that features high transmission with low iron content and an amazing anti-reflective coating on the back that reduces heat loss and improves light transmission.

Aluminum frame

Once the PV cell string is in place and the glass cover is in place, everything needs to be held in place by the frame, and for this part, aluminum frames are the ones in heavy use.

They are edge-mounted and tightly laminated to hold everything within that boundary in place, preventing them from moving even when the solar panel is shaken.

The reason why aluminum is the material of choice is that it is very light, which is very important given that most solar panels are placed on the roof; The last thing you want is to have something as heavy as steel pressing down on your roof.

The second reason why aluminum is the best option is that it is impermeable to rust and can withstand all weather conditions without breaking.

The last reason is that aluminum is a very strong metal that doesn't bend easily and can withstand any form of extreme stress.

EVA Film

It's ethylene vinyl acetate and it's a polymer that's designed to be transparent to be used specifically to encapsulate PV cells and hold them in place during fabrication.

This material must be very durable given the important work they do throughout the installation. 

They must withstand high temperatures, humidity, and any weather conditions that may be thrown at them.

The lifespan of your home solar panel largely depends on the ability of the EVA film to hold objects together; the longer it lasts, the longer your solar panels will serve your needs.

Back sheet

This is the part that makes up the back of the solar panel, the sole purpose of which is to keep moisture out of the back of the panel. This is the last barrier, the outer shell that provides electrical insulation and mechanical protection.

It is mainly made using different types of polymers, but PP, PVF and PET are the most common as they offer different levels of heat resistance, physical protection and UV resistance. 

Junction box and connectors

Like any other electrical device, the solar panel comes with a range of junction boxes and connectors that ensure that moisture does not get into the most sensitive parts of the electrical system, as this can cause problems.

The cables and wires needed to transmit power to the required devices are securely fastened inside the junction box, which is then tightly closed with bolts and screws.

Installation of solar panels with Solar Mounting Structure

Installing solar panels for home use is a long process that should be handled by a professional.

But depending on the size, this is an operation that anyone who is well versed in electrical systems can handle. Below are the main steps to install solar panels in your home.

Scaffolding: Scaffolding is erected here to increase the safety of the entire structure during operation. This is temporary and will be removed once the solar panel is installed.

Scaffolding gives contractors the ability to stand up and stand up to avoid falling to the ground.

Solar Panel Mounts: The next step is to install the solar panel mounts that will secure the panel to be held in place. The mounting structure can be built into the roof, which means drilling holes in the beams and fixing them securely with bolts and screws or tying them with suitable materials.

Make sure the mounts are tilted towards the sun to get maximum light; for best results, it should be in the range of 18-36 degrees.

Install solar panels: Once the mounts are up and running, it's time to test them out with the solar panel itself.

They must be part of the mounting structures, which means that they must be compatible. Luckily, each solar panel comes with its own panel mounts that are sized for them. Make sure all bolts are tight so items don't fall off.

Connect the solar panels: After securing the solar panels in place, it's time to connect the wiring. There are certain connectors called MC4 that are best suited for this kind of work, and they usually come with the panels when you buy them.

When handling wiring, make sure that all other sources of electricity in the house are turned off from the main switch to avoid accidents due to electric shock.

Install a Solar Inverter: Solar inverters are devices that complete the connection by converting the direct current generated by the solar panel into alternating current, which can then be picked up by the electrical grid and distributed to the rest of the home for use.

The solar inverter can be placed outside next to the solar panel itself, or wired from inside the house. What you should consider is that they work best when stored in a cool, moisture-free, and well-ventilated area.

Solar Panel: For a solar panel system to be effective, it must be connected to a battery, which ensures that all the energy converted into electricity is stored for later use.

Without some kind of storage mechanism, all you would have was electricity running during the day and waning when the sun goes down towards evening. It will also keep you from running out of power when the sky gets too cloudy.

Connect to the consumer unit: The inverter is then connected to the consumer unit to generate enough electricity that can be safely used in the house.

A generator meter should be connected to it, which will help you control your energy consumption. This will help you schedule multiple power-hungry machines around the house.

Start Test: Once you're satisfied with the connections you've just completed, it's time to check if something works. Turn on the main power, and if everything works, then you are ready to use the solar panel; if nothing happens, go through the entire installation to see where you went wrong.
