How much does a home solar light cost in San Diego

As of August 2024, the average solar panel system costs $2.36/W including installation in San Diego, CA. For a 5 kW installation, this comes out to about $11,800 before incentives, though prices range from $10,030 to $13,570. After the federal tax credit, the average price drops by 30%. You'll probably pay even less than what we show here.

Doubling the system size effectively doubles the price, so you'll pay about twice that for a 10 kW system, which would cost around $23,600 in San Diego, CA. The higher the price tag, though, the more you'll get back as a credit towards your federal tax bill.

Based on our binding quotes, solar panels typically cost between $3 to $4 per watt in California. You might find a lower figure elsewhere, but make sure that: The figures below are from a real quote for a 4.4 kW solar system presented to a solar.com customer in San Diego.

Even without the 30% federal tax credit, the cost of electricity from solar panels is more than four times cheaper than grid electricity in San Diego. And that's just in the first year. These savings can be expected to increase each year as the cost of electricity rises.

In San Diego, an average home needs a 5kW solar system in order cover most of their electricity needs. Given the average residential price-per-watt of $3.5 in San Diego, a 5kW system can cost around $17,500 depending on applicable rebates and other factors.

This is lower than the average price of residential solar power systems across the United States which is currently $3.00 per watt. The size of a solar panel system also plays a role in how much the installation will cost. Larger solar installations will typically have a lower cost per watt, because the panels can be purchased at a 'bulk price'.
