Solar Photovoltaic Panels

Solar PV - Our electrical engineers have a lot of experience in solar installation design, installation, and maintenance. Solar panels are an excellent method to save money and get control over your utility expenses. With energy providers raising their power prices, now is a perfect time to build a solar PV system.

What Are Solar Panels?

Switching to alternative energy sources has become critical in the twenty-first century. In Bedfordshire, solar power has become a popular source of energy for homes, offices, and other businesses.

Solar panels, commonly known as photovoltaic (PV) panels, are devices that convert sunlight into electricity. Light is made up of energy particles called "photons," which are turned into electricity.

Multiple solar cells make up a solar panel. When a huge number of solar cells are spread out across a vast region, they can create enough electricity to be useful.

PV cells are made of semi-conductive materials such as silicon. They feature a positive and negative layer that work together to form an electric field.


How Do Solar Panels Work?

Light energy is absorbed in the form of photons when sunlight strikes the semi-conductive substance in the solar PV cell. It loosens a number of electrons, which then float around freely in the cell.

Negatively and positively charged semi-conductors are pressed together to generate an electric field in solar PV cells that are precisely engineered.

The resulting field forces the floating electrons to travel in a precise direction, towards the cell's conductive metal plates. An energy current is the name given to this flow. The intensity of the current determines how much electricity each cell can generate. The current is guided into wires as soon as the free-floating electrons collide with the metal plates, allowing electrons to move as they would in any other source of energy generation.


What Are the Advantages of Using Solar Panels?

Despite their growing popularity, few people in Bedfordshire are aware of the advantages of solar panels. Here are some of the most significant benefits of solar panels.

Decreases Air Pollution

Fossil fuels emit a large number of pollutants, resulting in smog and unclean air. These contaminants are hazardous to human health as well as to the environment. Furthermore, visibility is reduced as pollutants are distributed throughout the air. Solar panels use the sun's energy to provide renewable energy that does not pollute the environment.

Improves Health

Cleaner air is produced by solar panels, which is beneficial to lung health. Surprisingly, solar power also helps individuals in vulnerable areas have more food security. The United Nations Development Program (UNDP) uses solar panels to empower women to establish their own energy companies. It contributes to their income and directly ensures their food security.

Reduces Electricity Bills

When you use solar panels to create your own electricity, you are no longer reliant on the power system. Your utility cost will decrease as a result. Solar panels can last for decades, allowing you to save money on your electricity bills in the long run. Some people, in fact, go completely off the grid.

Increases The Value Of The Home

Installing solar panels on your property will increase the value of your home. It occurs because you are now self-sufficient in terms of electricity and produce clean energy. Solar panels are a bit pricey, but the returns on your investment are well worth the money.

Low Maintenance Costs

Solar panel maintenance has become significantly easier and less expensive as a result of rapid technological improvements. Furthermore, most panels come with long-term guarantees. You don't need to spend a lot of money on panel maintenance; monthly cleaning will suffice.

Water consumption is reduced

Water is most typically used to generate power if your present source of energy does not rely on fossil fuels. Hydropower and nuclear energy both utilise a lot of water to generate electricity. Dams are sometimes built around water bodies to control how the water flows so that power can be generated. This approach, however, may have a harmful impact on the surrounding ecosystem. Solar panels do not use any water, therefore conserving a valuable resource.

Reduces reliance on non-renewable energy sources

Solar energy has the potential to lessen our reliance on non-renewable energy sources such as fossil fuels. It is advantageous since non-renewable resources produce pollutants that degrade air quality. Furthermore, non-renewable resources are inevitably depleted with time. Renewable energy sources, on the other hand, will never run out. When carbon emissions rise, so does solar heat retention. It has varying effects on different climates, causing some areas to cool while others to warm. As a result, weather patterns all around the world are becoming more volatile. Scientists and climatologists have established that renewable energy initiatives are required to combat climate change after extensive research and testing. We cut our carbon dioxide emissions and do not emit considerable amounts of pollutants into the air when we use solar energy.

Understanding The Flow Of Current

The electricity generated by the solar panels travels through a system of wires and into an inverter. Solar panels, on the other hand, generate direct current (DC), whereas buildings typically require alternating current (AC).

An inverter is a device that converts DC electricity into AC electricity, enabling it to be used on a daily basis.

After the electricity is converted to AC power, it is dispersed throughout the building through the breaker box (electrical panel). With solar energy, this electricity may now be used to power electronics.


What Happens To The Unused Electricity?

The excess electricity used by the breaker box is sent to the utility grid via the utility metre.

The utility metre is a device that monitors the flow of power between your home and the grid. The metre runs backwards if your solar energy system produces more electricity than you need, and you earn credits for the surplus through net metering.

When you use more electricity than your solar panel system provides, you draw power from the grid through the metre, which keeps the metre running regularly.


What Is The Procedure For Installing Solar Panels?

Prepare for the process that follows once you've decided to install solar panels in Bedfordshire. There is a lot that must be done to guarantee that solar panels are installed correctly.

1. Find A Solar Panel Installer

The first step in installing solar panels in Bedfordshire is to identify a qualified installer. The most crucial thing to keep in mind is that the installer should be MCS certified so that you can be confident in the work. MCS is a Department of Energy and Climate Change accreditation (DECC). It assures that manufacturers and installation of green technology meet the highest possible requirements. MCS approved businesses can be found on the MCS website.

2. Get A Quote

You can get a quote before or after you choose a solar panel specialist. The quote will include information on how long the project will take and how much it will cost. Obtaining numerous quotes might assist you in making an educated decision.

3. Home Assessment

A team from the installation firm will arrive with a licensed surveyor to conduct a thorough inspection. A salesperson will also be dispatched to present their various offerings. Do not feel compelled to sign a contract after the assessment. Instead, examine the facts and attempt to comprehend the installer's evaluation of your roof. Select an installer when you've got enough time to review the bids and comprehend the assessment.

4. Set Up Scaffolding

Scaffolding is erected on your roof to begin the installation process. Throughout the installation, it ensures the safety of the employees on the roof.

5. Mount Installation

Because the mounting will eventually support the solar panels, it is critical that it has a strong installation. Depending on your demands, roof-ground or flush mounts are available. Sturdiness and support are provided by the mounting framework. Because the panels must face specified orientations, the framework must be somewhat slanted. The tilt angle is usually between 18 and 36 degrees.

6. Install The Solar Panels

PV panels must be properly positioned in a specific direction. For maximum sunlight in the Northern Hemisphere, the panels should face south.

Facing East or West, on the other hand, will yield positive outcomes. It would be preferable if the panels faced north for places in the Southern Hemisphere. Tightening nuts and bolts are required to secure the solar panels to the mounting structure. It must be done with extreme caution to guarantee that the structure is strong and long-lasting.

7. Electrical Wiring

A solar panel system's amperage, power, and voltage define how the panels are linked to the wiring. Universal connections, such as MC4, are commonly used for wiring since they may be used with a variety of solar panels. There are two ways to link the panels to each other:

*Series Connection: The positive wire from one PV module is connected to the negative wire of another in a series connection. This type of wiring boosts the voltage and aligns it with the battery bank.

*Parallel Connection: Positive lines are connected to other positive wires, while negative wires are connected to other negative wires in a parallel connection. In such wiring, the voltage of each panel remains constant.

8. Connect To A Solar Inverter

The positive wire of the panel is linked to the inverter's positive terminal, while the negative wire is attached to the inverter's negative terminal to connect the solar panel system to a solar inverter.

9. Connect The Inverter To A Solar Battery & The Grid

The battery's positive terminal is linked to the inverter's positive terminal to connect the solar inverter to the solar battery. Both devices' negative terminals are also connected to each other. If you want to go off the grid, you'll need a solar battery to store backup electricity. It is, however, necessary to connect the inverter to the grid. The installers connect to the main power switchboard with a regular connector for this process. The output cable is then linked to the electric board, which is in charge of supplying power to the house.

10. Start Solar Inverter

You may use your solar inverter right away once all the electrical cabling and connections are finished. Many inverters have a digital display that shows the status of the solar unit's usage and generation.

How Long Does It Take To Install Solar PV?

You can get a quote and an estimate of how long the full process will take before you choose a supplier. The length of time depends on the intricacy and size of your solar panel system.

It takes a few weeks to acquire quotations and have installers come to your house. However, after you've chosen a supplier, the process won't take long.

In the case of ordinary sized panels, the actual installation should be completed within a day of the scaffolding being completed. Larger panels, on the other hand, may take longer.


Are Solar Panels Worth It?

To figure out whether solar panels are worthwhile, you must first recognise that they are a long-term investment.

Installing a solar panel system might be somewhat costly at first. The advantages, on the other hand, will be progressively realised.

Yes, solar panels are worthwhile in certain circumstances. You will get your money's worth if you generate enough energy and stay in the same house for an extended period of time.

Solar panels eventually pay for themselves over the course of several years.


What Are Solar Panels Made Of?

Solar panels are made up of many solar cells that absorb sunlight and convert it to electricity.

The fundamental material in most solar PV panels is crystalline silicon wafers. In reality, silicon is employed in the production of semi-conductors in nearly all solar panels on the market. The remaining 5% rely on experimental technologies like organic PV cells.

The semi-conductors are in charge of producing electricity. Their electrons are knocked loose when they come into contact with sunlight, resulting in the creation of electricity. The photovoltaic effect is the name given to this process.

Metal, glass, wire, and plastic are among the other components of PV cells. Solar panels are usually covered with a layer of glass. There is also an anti-reflective layer that protects the sensitive silicon cells while enabling light to pass through.

This entire framework is supported with plastic or polymer frames that are required for installation on both rooftop or ground-mounted solar panel systems.

Types Of Solar Panels

Today's solar panels come in a variety of shapes and sizes, thanks to advances in technology.


Solar panels made of mono-crystalline silicon are the most efficient. A single crystal is used to make these silicon panels. They are, however, the most costly sort of panel.


Although polycrystalline panels are not as efficient as mono-crystalline panels, they are a cost-effective alternative. Multiple silicon crystals have been fused together to create these silicon cells.


Thin-film solar cells, which are made of amorphous silicon, are the most flexible solar panels. They are, however, the least effective.
