What is Solar Photovoltaic (PV) Technology?
Solar Photovoltaic (PV) technology converts sunlight into electricity using solar cells made from semiconductor materials like silicon. When sunlight hits the panels, it causes electrons to move, generating electricity. This renewable energy source is becoming one of the most efficient ways to power homes and businesses.
Understanding Solar PV – The Basics Explained
Solar PV systems harness the power of sunlight to produce electricity. By using solar panels, they absorb light and convert it into electrical current. This technology is eco-friendly, reducing the need for fossil fuels while offering long-term savings on electricity bills.
How Does Solar Photovoltaic Work? A Simple Guide
Solar PV systems work by capturing sunlight through solar panels, converting it into direct current (DC) electricity. An inverter then changes the DC into alternating current (AC) electricity, which powers your home or business. Excess electricity can be stored in batteries or fed back into the grid.
Key Components of Solar Photovoltaic Systems
A solar PV system is composed of several components. Here’s a breakdown of the key parts:
| Component | Function |
|---|---|
| Solar Panels | Capture sunlight and convert it into electrical energy |
| Inverter | Converts DC electricity from the panels to AC electricity |
| Battery Storage | Stores excess electricity for later use (optional) |
| Mounting Structure | Supports the solar panels, either on the roof or ground |
| Charge Controller | Manages the flow of energy to the battery (if installed) |
