Brea is on standard Southern California Edison supply, which means the state Net Billing Tariff applies in full. Exported power earns considerably less than power you use yourself, so the value sits in self-consumption and in shifting your own production into the evening rather than sending it to the grid.
Brea sits against the hills at the top of the county, and that geography does real work on a solar design. Hillside lots bring slopes, varied roof orientations and neighbouring terrain that can shade a roof at times of day a flat-lot estimate never accounts for. This is a place where an aerial-only design is more likely to be wrong than usual.
Ask any installer quoting you to model the export credit on your actual supplier rather than a generic assumption, and to tell you whether the design came from a site survey or an aerial estimate.

Southern California Edison, on standard supply, so the state Net Billing Tariff applies in full.
It can change it a lot. Slopes give you roof planes at several different orientations rather than one good one, and neighbouring terrain can put a roof in shade at hours a flat-lot estimate never models. This is a place where the difference between a real site survey and an aerial guess shows up in the production number.
For most households here with a monthly bill over $150 the economics work, but the honest answer depends on your roof orientation and shading, how much power you use and when, your rate plan, and how you pay for the system. Those move the result far more than the choice of panel brand. The number worth having is the one on a real design for your address, which is what comparing quotes gives you.
California residential solar is generally quoted around $2.40 to $3.25 per watt in 2026, putting a typical system in the high teens to mid thirties of thousands before financing. Adding a battery usually adds $10,000 or more depending on capacity. Note that the federal residential clean energy credit expired on December 31, 2025, so a purchased system in 2026 does not carry it. Leases and power purchase agreements are treated differently, because the system owner is a business.
Under the state Net Billing Tariff, power you export earns far less than power you buy back during the evening peak, so storing your own production is generally worth more than exporting it. Whether that justifies the added cost depends on your usage pattern and your rate plan. If your address is served by a municipal utility, different rules may apply entirely.
Usually six to fourteen weeks from signing to switch-on. The crew is on your roof for one to three days of that. The two waits that actually decide your timeline are the building permit and your utility's permission to operate, and neither is under your installer's control.
