A solar panel system captures sunlight to generate electricity for your home or business. It typically consists of photovoltaic (PV) panels to collect energy, an inverter to make that energy usable, a battery for storage, and a meter to track usage.
Systems are generally categorized into three types, depending on how and where the energy is used:
1. Types of Systems
- Grid-Tied (On-Grid): The most common setup. Your panels connect to the utility grid. When you produce more power than you use, the excess is sent back to the grid (often earning you credits). When you need more power than you produce, you pull from the grid.
- Hybrid (Grid-Tied with Battery): This functions similarly to a grid-tied system but includes a battery bank. It protects you during power outages and lets you use stored solar power at night.
- Off-Grid: Completely independent of the local utility grid. It requires a robust battery bank to store energy for nighttime use or days with less sunlight.
2. Main Components
- Solar Panels: Placed on your roof or a ground mount, they absorb sunlight and convert it into direct current (DC) electricity.
- Solar Inverter: Converts the DC electricity from the panels into alternating current (AC), which is the standard type of electricity used by household appliances.
- Battery Storage: An optional (but recommended) component that holds extra solar energy to be used during the evening, peak utility hours, or blackouts.
- Utility / Smart Meter: Tracks both the electricity your system imports from the grid and the excess power it exports.
3. How It Works at a Glance
- Absorption: Panels absorb sunlight and create a DC electrical charge.
- Conversion: The inverter translates this energy into usable AC electricity.
- Usage: The electricity powers your home.
- Storage/Export: Excess power either charges your battery or is fed back to the power grid.
