A Simple, Honest Guide to Turning Sunlight into Power
Solar panels have become a familiar sight across Australia, quietly working on rooftops, farms, and remote properties. They look simple, but behind that simplicity is a clever process that turns sunlight into usable electricity for everyday life. Here’s how it all works, clearly explained, without the jargon.
What Are Solar Panels Made Of?
Solar panels are made up of many small units called photovoltaic (PV) cells. These cells are typically made from silicon, a material that reacts when exposed to light. Each panel is sealed under toughened glass and framed with aluminium to protect it from weather, heat, and time. How Sunlight Becomes Electricity
When sunlight hits a solar panel, it brings energy in the form of tiny particles called photons. These photons strike the PV cells and transfer energy to electrons inside the silicon. Once energised, the electrons begin to move.
Inside each solar cell, two layers of silicon create an internal electric field. This field pushes the moving electrons in one direction, creating an electrical flow. This process is known as the photovoltaic effect, and it is the core principle behind solar power.
Why Solar Panels Produce DC Power?
The electricity generated by solar panels flows in a single direction. This type of electricity is called direct current (DC). DC power is ideal for generation but cannot be used directly by most household appliances, which rely on alternating current.
Because sunlight changes throughout the day, the amount of DC power produced also changes, rising with strong sunlight and falling with clouds or shade.
The Role of the Solar Inverter
The solar inverter is what makes solar power usable. It converts DC electricity into alternating current (AC), which is the type of electricity used in homes and businesses.
Beyond conversion, the inverter also:
- Regulates voltage and frequency
- Monitors system performance
- Manages grid connection and safety
- Shuts the system down automatically if a fault occur.
Without an inverter, solar panels cannot power everyday appliances.
How Solar Power Is Used in Your Home
Once converted to AC, solar electricity is used by your home or business first. Appliances running during the day can be powered directly by solar energy, reducing reliance on grid electricity.
If the system generates more electricity than you are using, the excess power is either stored in batteries or exported to the grid, depending on your setup.
Solar Batteries and Energy Storage
Battery storage increases energy independence and is especially valuable for off-grid and hybrid solar systems.Solar batteries store excess electricity generated during the day for use later. This allows solar power to be used at night, during peak pricing periods, or during power outages.
Do Solar Panels Work on Cloudy Days?
Yes, they do. Solar panels rely on light, not heat. Even on cloudy or overcast days, diffused sunlight reaches the panels and allows them to generate electricity. While output is lower than on sunny days, solar systems continue producing power year-round.
What Affects Solar System Performance?
Several factors influence how much electricity a solar system produces:
- Amount of sunlight received
- Panel orientation and tilt
- Shade from trees or buildings
- Temperature
- Overall system design and component quality
A well-designed system maximises output across different seasons.
How Long Do Solar Panels Last?
Solar panels are built for longevity. With no moving parts, they require very little maintenance and can continue generating electricity for decades. Over time, output slowly decreases, but quality systems remain reliable and efficient long-term.
