How Do Solar Panels Work?
Solar panels are an incredible innovation that harness the power of the sun to generate electricity.
But how exactly do they work? Let’s dive into the science and technology behind solar panels to understand the process that transforms sunlight into usable energy for homes and businesses.
The Science Behind Solar Panels
Solar panels operate using photovoltaic (PV) technology. The term “photovoltaic” comes from “photo” meaning light and “voltaic” referring to electricity. This technology allows solar panels to convert sunlight into direct current (DC) electricity.
Here’s how it works step-by-step:
Sunlight Hits the Solar Panels
Solar panels are made up of photovoltaic cells, usually crafted from silicon. When sunlight hits these cells, the energy from the light excites electrons within the silicon, creating an electric current.Generating an Electric Current
Each photovoltaic cell is designed with layers of silicon. One layer is positively charged, and the other is negatively charged. The interaction between these layers and sunlight generates an electric field, causing electrons to flow. This flow of electrons is what creates direct current (DC) electricity.Inverting the Power
Homes and businesses use alternating current (AC) electricity, not DC. To make the electricity usable, the DC electricity generated by the solar panels passes through an inverter. The inverter converts DC into AC, ensuring compatibility with your appliances and the grid.Powering Your Property
Once converted, the AC electricity can either be used immediately to power your property or stored in a battery for later use. Any excess energy can often be sent back to the grid, depending on your system and local energy regulations, earning you credits or payments.
What Are Solar Panels Made Of?
How do solar panels work? The main components of a solar panel include:
- Photovoltaic Cells: Silicon-based cells that absorb sunlight.
- Glass Layer: Protects the cells from weather and physical damage.
- Encapsulation: Ensures durability and insulation of the cells.
- Metal Frame: Provides structural support and makes installation easier.
- Junction Box and Wiring: Facilitates the flow of electricity to the inverter.
Factors That Affect Solar Panel Efficiency
The efficiency of solar panels depends on several factors:
- Sunlight Availability: Panels produce more energy in areas with higher levels of sunlight.
- Panel Orientation: Panels should ideally face south in the UK for maximum exposure.
- Shading: Obstructions like trees, chimneys, or neighbouring buildings can reduce energy production.
- Panel Quality: Higher-quality panels typically offer better efficiency and longevity.
