As of July 2024, the average solar panel system costs $2.61/W including installation in Newcastle, CA. For a 5 kW installation, this comes out to about $13,038 before incentives, though prices range from $11,082 to $14,994. After the federal tax credit, the average price drops by 30%.

You'll probably pay even less than what we show here. It doesn't include the federal ITC or Newcastle, CA state incentives, which will lower this price by at least a few thousand dollars.

Your solar panel cost depends on your system's size

It may seem obvious but larger solar panel systems cost more money. We use cost per watt ($/W) so you can easily compare quotes, controlling for slight variations in system size.

While a 5 kW system will only cost you $13,038 in Newcastle, CA, doubling the system size effectively doubles the price, so you'll pay about twice that for a 10 kW system. The higher the price tag, though, the more you'll get back as a credit towards your federal tax bill.

If you can't shell out $13,038 in cash to pay for solar, don't sweat it. You can choose to finance your system with a loan instead. Some companies even offer $0-down loans so you can start saving on day one if your loan payments are less than your current electric bills. Just keep in mind that your long-term savings will be lower with a loan due to interest rates.

Solar is a major purchase, but you can get the price tag to come down a bit by being an educated shopper. Taking advantage of incentives and rebates and shopping around for quotes can bring down your cost of solar in Newcastle, CA.

Take advantage of federal and local solar incentives

As long as your federal tax bill is high enough, you can take advantage of the federal tax credit in Newcastle, CA. This incentive allows you to apply 30% of your solar installation and equipment costs toward your federal tax bill. If the amount exceeds your tax bill, you can roll over the remaining credit to the following year. Many states also offer great local incentives and rebates.
