Solar panel systems in California cost an average of $3 per watt. For a typical 5-kilowatt (kW) system, this means homeowners can expect to pay $15,000 to $17,000 before applying incentives.
| System Size (kW) | Cost Before Incentives | Cost After 30% Federal Tax Credit |
| 4 kW | $12,000–$14,000 | $8,400–$9,800 |
| 5 kW | $15,000–$17,000 | $10,500–$11,900 |
| 6 kW | $18,000–$20,000 | $12,600–$14,000 |
| 10 kW | $30,000–$34,000 | $21,000–$23,800 |
The size of your solar system depends on your home’s energy usage. Larger systems cost more upfront but can offset a higher percentage of your energy bill over time.
Choose the right type of panel for your needs:
Premium inverters, panels, and other system components cost more upfront but deliver better performance, energy savings, and warranties.
Factors like roof shape, material, shading, and orientation impact installation costs. Complex roofs or shaded areas may require additional equipment to optimize production.
Your contractor can significantly influence your project’s cost and quality. Supreme Solar and Electric guarantees competitive pricing, expert installation, and excellent customer service.
