The valley gets the sun to make solar work, but California's net metering rules changed substantially with NEM 3.0, which shifted the economics toward pairing panels with battery storage rather than exporting to the grid.

Hiring solar in Temecula — what to know

Is solar still worth it under NEM 3.0?

The maths changed rather than disappeared. Export credits are far lower than under the old rules, which pushes most new systems toward battery storage so you use your own generation instead of selling it cheaply.

What licence should a solar installer hold?

Typically a C-46 solar licence, or a C-10 electrical licence. Both are legitimate for photovoltaic work — verify whichever they claim.

How does valley heat affect panels?

Panels lose a little efficiency as they get hotter, which is why real-world output on a 105°F afternoon is below the rated figure. Good installers account for it in their production estimates.
