From Sunlight to Energy: How is Solar Energy Converted into Electricity?

When it comes to renewable energy sources, solar energy stands out as one of the most environmentally friendly options. Not only does it offer economic benefits, but it also makes a positive contribution to the environment, earning its reputation as one of the cleanest energy sources available.

In addition to its environmental advantages, solar energy is also highly beneficial from a financial perspective for homes, businesses, and farms.

However, you might be wondering: how exactly is energy from the sun converted into electricity? And what advantages can it bring to everyday life?

What is Solar Energy?

To understand the concept of solar energy, it’s essential to start with the basics of photovoltaic solar power, a critical step in exploring this renewable energy source.

In simple terms, solar energy is the process of converting sunlight directly into electricity using photovoltaic cells. These cells are integrated into solar panels, which capture sunlight and generate clean, renewable energy without producing harmful emissions.

Unlike fossil fuels, solar power generates electricity without releasing greenhouse gases or pollutants, making it an essential resource in reducing carbon emissions and addressing global warming. By using the power of the sun, solar energy provides an environmentally friendly alternative to traditional energy sources, helping to protect the planet for future generations.

How is Solar Energy Converted into Electricity?

Solar energy is transformed into electricity through photovoltaic (PV) technology, a clean and sustainable process. Solar panels are made up of multiple photovoltaic cells, which are crafted from semiconductive materials like silicon.

These materials are designed with two layers: one positively charged (p-type) and the other negatively charged (n-type).

When sunlight, composed of particles called photons, strikes the surface of the PV cells, it energises electrons within the semiconductive material. This movement of electrons generates direct current (DC) electricity.

For this energy to be usable, it is necessary to convert the direct current (DC) generated by the solar panels into alternating current (AC).

This process is carried out by the solar inverter, which modifies the electrical current, making it suitable for use in homes, businesses, public buildings, companies, and industries.

It’s worth noting that this process continues even on rainy or cloudy days, although at a reduced and slower rate than usual.

How a Solar Panel System Works: Step by Step

Storing Solar Energy: A Reliable Solution

One limitation of solar panels is their inability to generate electricity at night or during periods without sufficient sunlight. However, storing solar energy provides a practical solution to this challenge.

Solar Batteries

During sunny days, your solar panel system often produces more energy than you need. This surplus energy can be stored in a solar battery for later use. By using stored solar energy at night, you can reduce your reliance on the grid and cut energy costs.

One major advantage of certain brands of solar batteries is their ability to provide backup power during outages while protecting you from fluctuating energy prices. This ensures you always have access to clean, renewable energy.

The Smart Export Guarantee (SEG)

In the UK, the Smart Export Guarantee (SEG) program enables homeowners to earn money for the excess electricity they generate. Suppliers participating in this scheme offer a fixed tariff for every unit of energy exported to the grid. Since tariffs vary among providers, it’s worth comparing options to maximise your return.
