Solar is reasonable in Murrieta, not spectacular. A 8.2-year payback still beats most savings accounts over the panel's 25-year life, but it is not the slam dunk you'll see advertised.
California no longer pays full price for exported power. Under net billing, power you send to the grid earns about 20% of what you pay to buy it back, rather than the one-for-one credit older net metering gave. Because a system without a battery exports most of what it makes, this lengthens payback substantially — and it is why our figures here are lower than calculators still assuming one-for-one credit. A battery raises the share you use yourself and shortens payback, at the cost of adding $8,000–15,000 to the system.

Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.

Why Murrieta gets 1,963 sun hours

That figure comes from Google's analysis of real rooftops across Murrieta — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Murrieta reaches about 2,063 hours, roughly 5% better than typical.
