Solar Panel Efficiency and Components

Study Notes

Panel Efficiency

Measures the percentage of sunlight that is converted into electrical energy
Affects the overall performance and cost-effectiveness of a solar panel system
Factors that influence panel efficiency:
- Temperature: High temperatures reduce efficiency
- Shading: Shaded areas reduce efficiency
- Angle of incidence: Optimal angle of incidence varies depending on location and time of day
Commercial solar panels typically have an efficiency range of 15-20%

Solar Cell Materials

Monocrystalline Silicon (mono-Si)
- High efficiency rates (15-20%)
- High manufacturing cost
- Used in high-efficiency solar panels
Polycrystalline Silicon (poly-Si)
- Lower efficiency rates (12-15%)
- Lower manufacturing cost
- Used in standard solar panels
Thin-Film Solar Cells
- Lower efficiency rates (7-14%)
- Lower manufacturing cost
- Flexible and lightweight
Organic Photovoltaic Cells (OPVs)
- Lower efficiency rates (3-5%)
- Lower manufacturing cost
- Flexible and lightweight

Inverter Systems

String Inverters
- Convert DC power from solar panels to AC power
- Centralized inverter system
- Economical and widely used
Microinverters
- Convert DC power from individual solar panels to AC power
- Decentralized inverter system
- More efficient and reliable
Power Optimizers
- Optimize energy output from individual solar panels
- Used in conjunction with string inverters
- Improve system efficiency and reliability
Inverter Efficiency
- Measures the percentage of DC power converted to AC power
- Affects the overall performance of a solar panel system
- Commercial inverters typically have an efficiency range of 95-98%
