You’ll probably pay even less than what we show here. It doesn’t include the federal ITC or Los Gatos, 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 $13,800 in Los Gatos, 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.
