Study Notes
Photovoltaic Cells
- Convert sunlight into electrical energy through the photovoltaic effect
- Made from semiconducting materials like silicon, which release electrons when exposed to sunlight
- Cells are grouped together to form a module, and multiple modules make up a solar panel
- Efficiency varies depending on the type of photovoltaic cell:
- Monocrystalline silicon: 15-20% efficient
- Polycrystalline silicon: 12-15% efficient
- Thin-film: 7-14% efficient
Solar Panel Installation
- Factors affecting installation:
- Roof size and orientation
- Shading from trees, buildings, or other obstacles
- Local building codes and regulations
- Installation types:
- Roof-mounted systems: attached directly to the roof
- Ground-mounted systems: installed on the ground
- Tracking systems: move to follow the sun's path
Solar Panel Efficiency
- Efficiency measures the percentage of sunlight converted into electricity
- Average efficiency of commercial solar panels: 15-20%
- Factors affecting efficiency:
- Temperature: high temperatures reduce efficiency
- Dirt and debris: reduce efficiency by blocking sunlight
- Angle and orientation: optimal angle and orientation increase efficiency
Energy Storage
- Purpose: store excess energy generated by solar panels for later use
- Types of energy storage:
- Batteries: deep cycle batteries, lithium-ion batteries
- Other options: flywheels, capacitors, hydrogen fuel cells
- Importance of energy storage:
- Provides backup power during outages
- Enables efficient use of excess energy
- Stabilizes the grid by smoothing out peak demand
Renewable Energy Systems
- Solar panels are a key component of renewable energy systems
- Other components:
- Wind turbines
- Hydroelectric power
- Geothermal energy
- Benefits of renewable energy systems:
- Reduces greenhouse gas emissions
- Diversifies energy sources
- Increases energy independence
