The Science Behind Solar Cells

Scientific basics are vital to understanding any technology. Since a solar panel system uses PV cells for energy conversion, it is interesting to know the fundamentals behind the working.

A solar cell is made of three layers.

  • Antireflection layer
  • Energy-conversion layer
  • Electrical contact layer

The first layer traps incident light and transmits it to the energy-conversion layers. Next, the second layer converts light energy into electricity.

Finally, the electric contact layers carry this current to the external load. Hence, the same process takes place in a solar power system.

It is still vital to realise that these steps are just a simple explanation. If you delve deep, you will find much information about solar cell layers.

However, as a solar system consumer, these fundamentals are enough to understand the working principle.

The growing utility of solar cells leads to a decrease in dependency on fossil fuels. Hence, there is a direct decline in greenhouse gases emissions.

In addition, solar cells help develop innovative products that do not require traditional energy sources. So, alternatives like a solar power plant, off-grid solar installation, and solar farms are possible due to these wonderful cells.

Reduces Electricity Bills

House Solar PanelsThe direct pro or advantage of solar cells is the installation of a solar energy system. So, you can use the free energy available from the sun and power your gadgets.

This installation leads to a gradual decline in your monthly electric bill. Also, you can send the surplus energy back to the power grid in some locations.

Such cost-saving solar energy pros are a direct result of solar cells. Hence, these cells give you your money’s worth in the long run.

Zero Harm to the Environment

In addition to combating rising energy costs, solar cells help prevent any environmental impact. Solar systems do not emit harmful pollutants or chemicals.

Also, solar cells do not produce any noise during energy conversion. This factor is vital for mass installation in urban areas.

Thus, adding solar panels is an environmentally friendly activity. You can also produce power in a flexible way without any damage to nature.

Ease in Installation

You can set up solar panels on the ground or roof space without much hassle. The robust solar cells make such designs possible.

Solar arrays are large in size but easy to install at desired locations. Hence, this ergonomic nature of PV cells leads to a minimum effect on our lifestyle.

Also, the potential to arrange these cells in different configurations makes them useful in intricate locations.

Solar System Incentives

In the UK, you can avail of incentives and grants for solar panel installation. So, you end up reducing electricity bills along with lucrative government grants.

This combined benefit leads to instant energy independence at a reasonable budget. At this time, solar incentives and a competitive market have lowered the high initial cost.

So, you can install battery storage without spending too much money. All these economic benefits are a result of solar grants, which are directly linked to solar cells.

Long Service Life

Solar panels made from PV cells last for 25 to 30 years. This long service duration is enough to prove the durability and robustness of these systems.

Hence, you can cover the upfront installation costs due to durable solar cells that require low maintenance and replacement.

In addition, all the panels installed on your rooftop remain efficient without maintenance for a longer duration.

Cons Of Solar Cells

The benefits of PV or solar cells are encouraging. However, you should also analyse some practical limitations and disadvantages of these items.

Highly Expensive, But There is a Catch

Solar installations need a high initial investment. This high price is a result of material, labour, and installation costs.

However, you can use solar financing options from governments and companies to combat this challenge. Also, the cost of solar cells and related equipment has declined in the past decade.

Concepts like net metering allow consumers to install solar panels in an under-control budget.

High Dependency On Sunlight

Solar panels and cells cannot operate without sunlight. You will notice the same point in any information explaining the cons of solar energy.
