1. Average Costs by System Size
| System Size | Average Cost (Before Incentives) | Homes It Powers |
|---|---|---|
| 4 kW | $11,200 | 800-1,200 sq ft |
| 6 kW | $16,800 | 1,500-2,000 sq ft |
| 8 kW | $22,400 | 2,000-2,800 sq ft |
| 10 kW | $28,000 | 3,000+ sq ft |
Note: Prices reflect national averages after 30% federal tax credit
2. Cost per Square Foot
- $3-$5/sq ft for most homes
- Small homes (under 1,500 sq ft): $4.50-$6/sq ft
- Large homes (over 3,000 sq ft): $2.75-$3.75/sq ft
Example: 2,000 sq ft home would pay $7,000-$10,000 after incentives
3 Key Factors Affecting Your Solar Costs
1. Roof Characteristics
- Material: Asphalt shingles easiest/cheapest ($0.10/W less than tile)
- Pitch: 30° slope ideal (extreme angles add 5-15% to cost)
- Obstructions: Skylights/chimneys increase labor time
2. Local Incentives
- Federal Tax Credit: 30% until 2032
- State Programs:
- CA: $3/Watt rebates
- NY: Property tax exemptions
- TX: Net metering required
3. Equipment Choices
| Option | Price Impact | Efficiency |
|---|---|---|
| Basic Panels | $2.50/W | 16-18% |
| Premium Panels | $3.25/W | 20-22% |
| Microinverters | +$0.30/W | Better shade handling |
