Understanding Solar Panel Systems
Solar panel systems convert sunlight into electricity through photovoltaic cells.
- Monocrystalline Panels Highest efficiency, premium cost. Best for limited space.
- Polycrystalline Panels Good efficiency, more affordable. Suitable for most installations.
- Thin Film Panels Flexible, lightweight. Lower efficiency but works well in high temperatures.
- Bifacial Panels Captures light on both sides. Ideal for specific installations.
Installation Factors
Roof Orientation
South-facing is optimal in Northern Hemisphere. Consider shade and obstructions.
Structural Support
Ensure roof can support panel weight. Consider wind and snow loads.
Local Climate
Account for temperature, precipitation, and seasonal variations.
Grid Connection
Check utility requirements and interconnection standards.
Financial Considerations
- Federal Tax Credits Currently 30% of total system cost through 2032.
- State Incentives Vary by location. May include rebates, grants, or tax benefits.
- Net Metering Credit for excess power sent to grid. Policies vary by utility.
- Property Value Solar installations typically increase home value.
