A COMPLETE GUIDE TO SOLAR PANELS–2022

Solar power is an excellent way to generate sustainable energy, and it's becoming increasingly popular in the UK. By adopting this green power system, you can lessen your carbon footprints, and utility bills altogether. You may have heard about solar panels, but are unsure how they work or whether they're suitable for your residential and business needs. This article will give you the complete information about the Solar Photovoltaic Panels:

Solar PV Energy

The infinite green energy uses a medium of energy that is taken from the sun rays exposure. It is clean, renewable, and uses no harmful chemicals or pollutants to create electricity. Solar panels generate electricity for residential, business, and commercial sectors around the world.

What does a Solar PV panel mean?

A solar PV array is a fabricated cell that allows the sun's irradiance (photons in sunlight) to jump into its surface membrane and convert it to usable power. The amount of power produced by your solar PV panels depends on how much sun rays (photons) hit its exterior membrane surface, which orientation they are, and the manufacturing material.

The Most Common Solar Panel variants

Solar Photovoltaic panels are manufactured of – monocrystalline, polycrystalline, thin-film, and amorphous.

Monocrystalline Solar Panels
Monocrystalline panels have become the most popular because they are efficient and have a long lifespan. These photovoltaic panels are more expensive, but their cost is good enough to justify them because they last for 20-25 years, compared to other types of solar panels that have a 10- to 15-year manufacturing warranty.

Polycrystalline Solar Panels
These are often made from amorphous silicon instead of single crystals like monocrystalline. They are, nevertheless, more affordable than their contemporaries yet provide less efficiency. Polycrystalline, on the other extreme, has a short warranty of about 10 to 15 years. So if you want something that will last longer then an option for mono or thin film is available.

Thin Film Solar PV Panels
Instead of just a monolayer, Thin Film Solar PV Panels utilize multiple layers of materials like cadmium telluride or copper indium gallium selenide. As no residual products produce at the manufacturing stage, they are more adaptable than other variants.

Monocrystalline vs Polycrystalline Solar Panels
Polycrystalline solar PV panels are generally cheaper than monocrystalline solar panels. This is because they use less material and therefore have a lower production cost. On the other extreme, the monocrystalline cells have higher efficiency (from 15 - 20 %) and durability than their polycrystalline counterparts (generally from 13 - 16%). Polycrystalline does have some advantages over monocrystalline depending upon the following scenarios:

- Where Off-Peak hours last for a long time;
- The roof has limited space for mounting.

Thin Film Solar PV Panels

What is the functionality of a Solar Panel?

Solar green energy derives its power when exposed to the sun's irradiance. Solar cells are photovoltaics capable of transforming shining light into current power. A solar cell has two layers of semiconductor material with different band gaps (Valence band and Conduction band). When exposed to ultraviolet light, the Solar PV Panel materials let the photons pass through the Solar PV array outer membrane surfaces and release electrons in silicon atom valence bands. As a result of this, an electric Direct current is generated when electrons jump from one layer to another.

How long Solar Panel last?

Solar PV panels don't come with an everlasting warranty; they usually last between 20-25 years before they stop working properly. Some manufacturing companies offer a manufacturing and performance guarantee for around 25-30 years.

Solar Panel approval REA and FiT Scheme Policy?

Before purchasing the Solar Panel confirm that the Panels are approved by the MCS authorities. The MCS product approval allows solar panel manufacturers to market their panels. The MCS certified that the products are manufactured in a green-friendly environment, and the manufacturer's product is accredited by the laboratory test. The responsible authorities – REA and FiT approve that renewable products like solar panels, inverters, and batteries have MCS certifications and allow you to implant Solar PV Power System.

Which Direction Should My Solar Panels Face?

It's important to consider the direction of your solar panels before you install them. It's also important to consider the azimuth of solar panels that allows them to absorb much energy. In an area where autonomy days are more than usual, you can mount solar panels facing south. This way, you will get optimal energy from sunlight, without being blocked by clouds or rainy weather conditions. Solar PV panels can mount in any direction in some places of the earth that are close to the equator because there is no distinction between "north" and "south”, all directions are considered optimal for collecting energy from sunlight, and you can mount the solar panel in any direction.

Types of Solar Panels Mounting?

Solar Panels mounts are available in different mounting systems according to the needs of the customer. When choosing the best Solar PV Panel mounting system from many available other mounting systems, it is crucial to know how long it lasts and which best fits your needs. It comes with many different racking materials. Rails and mounting systems.

Solar Panel Mounting racking system material

Aluminum
Aluminum is used in solar panel mounting manufacturing because they are lightweight and easy to install, and non-corrosive.

Stainless steel
It is a commonly used material because it lasts for a long time and is strong and has resistivity to sustain snow, rainy, humid climates.

Wood
Wood is lightweight, sturdy, and easy to install but has chances to burn and is not good for hail, snowy, wet, and humid climates.

Iron
A good altar for the wood PV mounting racks, but has chances to corrode and is not the best fit for wet and humid climates.

Solar PV panel mounting frames

Solar Photovoltaic mounting frames (structures) variants are-- Solar PV Panel fixed mounting systems, and Solar PV Panel adjustable mounting systems.

Solar PV Panel Fixed Mounting Systems

Fixed Photovoltaic mounting systems are held in place on your rooftop or ground, while adjustable racking systems have flexibility to move to azimuths in accordance with the sun rays.

Solar Panel Pole mounting system

The Solar PV Panels are placed vertically high and fixed on the ground and mount Solar PV panels on the top of a pole in such a way that they will directly face the sun's rays exposure during the peak hours (early morning, noon, and early evening).

Ground mounting

The structures mount on the ground with the tag in its name. Its anchor angle adjusts with latitude measurements and calculations and after that, solar panels fix on its frames. All bolts, washers, and frames used in this system are of galvanized steel to resist the environmental corrosive effect.

Roof mounting system of solar panels

It mounts on the rooftop using bolts to the top surface of the wall at one end and then sliding over a bracket at the other.

Roof Grounded mounting

As named tagging, its structure is the best fit for ground mounting purposes but can mount on the roof top and provide flexibility in adjusting and fixing its design. Other solar panel mounting designs include Ballasted mounting, a Flush-mounting system, and many more.

Roof Grounded mounting

Solar PV Panel adjustable mounting systems

SmartFlower
SmartFlower solar panels are a new generation of solar power products. Its design is similar to a tracking system. Smartflower is made up of flexible solar cells, which bend with movement to adjust perpendicular to the sun's radiations.

Solar PV Panel adjustable mounting systems

Solar PV Panel Tracking adjustable mounting system
Those adjustable mounting systems of solar panels can mechanically adjust themselves according to the solar radiation exposure. The design can calculate the maximum radiation angle and based on that calculation decided to adjust itself to get maximum energy in peak hours.

Conclusion

There is a drastic focus on producing clean green energy in the solar sector in the UK due to its benefits. The most common benefit is that it reduces your electricity bills, reduces your dependency on the national grid, and helps to put your contribution to lowering carbon footprints. You can even get extra bucks by selling energy back to the national grid which is more than your demand. Hopefully, the information delivered in this article has given clarity in your mind about your questions related to solar PV panels to some extent.
