## Analysis Patterns

### Success Factors
- **Clear Images**: High confidence (80%+)
- **Large Roofs**: Better economics of scale
- **Good Condition**: Lower maintenance costs
- **South Orientation**: Maximum energy production

### Common Challenges
- **Shading**: Trees, buildings reduce efficiency
- **Complex Roofs**: Higher installation costs
- **Poor Images**: Lower confidence scores
- **Small Areas**: Limited system size options

### Indian Market Insights
- **Typical Payback**: 10-15 years in India
- **Government Support**: 30% subsidy makes most projects viable
- **Regional Variations**: Consider local electricity rates
- **Seasonal Factors**: Monsoon impact on installation timing
