Identify high-quality B2C sales leads from new installations in MaStR registry. **Lead scoring system (0-100 points)**:

**Scoring Components**:
- **Commissioning date (40 points)**: Newer installations score higher - optimal contact window is 1-90 days after commissioning
- **Installation size (30 points)**: Prosumer sweet spot (5-15 kWp for solar) - indicates purchasing power and potential for additional products
- **Location (20 points)**: High-income areas, favorable demographics, low competition
- **Type (10 points)**: Solar + storage combo = premium lead (higher ARPU potential)

**Customer Segments**:
- **Residential Solar** (5-10 kWp): ARPU 600€, LTV 3k€ - Offer prosumer tariffs, storage retrofit
- **Prosumer Solar** (10-30 kWp): ARPU 1,450€, LTV 10k€ - **HIGH PRIORITY!** Premium tariffs, storage, wallbox
- **Storage Systems**: Cross-sell EV tariff, dynamic tariff, wallbox
- **Wallbox Owners**: Cross-sell dynamic tariff, solar retrofit
- **Heat Pumps**: Offer time-of-use tariff, optimization service

**Use Cases**:
- B2C customer acquisition campaigns
- Prosumer tariff marketing (highest ARPU segment)
- Storage retrofit campaigns (upsell to existing solar customers)
- Cross-sell opportunities (wallbox → dynamic tariff, solar → storage)
- Territory planning for sales teams

**Best Practices**:
- Contact window: 30-90 days after commissioning (sweet spot for engagement)
- Focus on prosumer segment (10-30 kWp) for maximum ROI
- Batch campaigns by postal code for efficient field sales
