How Solar Panels Work
Solar panels operate by converting sunlight into electricity through a process known as the photovoltaic effect. When sunlight hits the solar cells within a panel, it causes electrons in the cells to become energised and move, creating an electric current. These solar cells are typically made from silicon and are arranged in a grid-like pattern on the panel. The generated direct current (DC) electricity is then channelled through an inverter, which converts it into alternating current (AC) electricity. This AC electricity is what powers your home. Any excess electricity produced can be stored in batteries or fed back into the grid, often earning you credits or payments. Understanding this process is fundamental for appreciating how solar energy systems can effectively cut down on electricity costs and contribute to a sustainable energy future. This straightforward technology is both efficient and increasingly accessible to homeowners.
Types of Solar Panels
When choosing solar panels, homeowners typically encounter three main types: monocrystalline, polycrystalline, and thin-film. Monocrystalline panels are made from a single crystal structure, making them highly efficient and durable, albeit at a higher price point. They are recognisable by their uniform dark appearance and rounded edges.
Polycrystalline panels, on the other hand, are created from multiple silicon crystals. They tend to be less efficient than monocrystalline panels but are more affordable. These panels have a bluish hue and a square cut, resulting in less waste during production.
Thin-film panels are made by depositing photovoltaic material onto a substrate. These panels are lightweight and flexible, making them suitable for unconventional surfaces. However, they generally offer lower efficiency and require more space to produce the same amount of energy as crystalline panels.
Understanding these differences is critical when selecting the type of panel that best fits your needs and budget.
