Solar Panels 101: Everything You Need to Know

Solar panels are devices that convert sunlight into electricity using photovoltaic (PV) cells. They are a cornerstone of renewable energy and are widely used in homes, businesses, and large-scale solar farms.

### Types of Solar Panels

- **Monocrystalline:** Made from a single crystal of silicon. Highest efficiency (~20-22%) but more expensive.

- **Polycrystalline:** Made from multiple silicon crystals. Slightly lower efficiency (~15-18%), more affordable.

- **Thin-Film:** Lightweight, flexible, less efficient (~10-12%), ideal for unconventional surfaces.

### Advantages

1. **Lower Energy Bills:** Generate your own electricity and reduce dependence on the grid.

2. **Environmental Impact:** Solar energy reduces greenhouse gas emissions.

3. **Durability:** Most panels last 25-30 years with minimal maintenance.

### Installation Tips

- Place panels facing north (in Australia) for maximum sun exposure.

- Avoid shading from trees or nearby buildings.

- Hire a certified professional for safe and efficient installation.

Solar panels can be combined with **solar storage batteries** to provide energy even at night, making your home or business more energy-independent.
