California solar, sized from your electric bill

California bills run high in a lot of metros, and time-of-use makes *when* you use power part of the story. A coastal place and a Central Valley house with afternoon AC still aren’t one stereotype. Start with the kWh you already buy.

Usage pattern beats a California average

Los Angeles and San Diego don’t share a load with Sacramento or Fresno. The San Francisco Bay Area and San Jose add their own climate and occupancy mix. TOU curiosity is real — it still doesn’t replace the statement in your hand. Paste the bill (or enter kWh). You leave with a kW ballpark and payment shapes you can take to a real quote.

PG&E, SCE, SDG&E — and everyone else

The big investor-owned utilities cover huge stretches of the state; munis, CCAs, and other providers sit beside them. Net metering and export-credit rules vary by utility and can change. We won’t invent an export rate for a headline. Helio stays a ballpark from usage; the installer confirms what applies to your meter.

Solar cost in California

There is no honest statewide California solar price. Cost follows size; size follows the kWh you already buy — coastal vs Central Valley loads are not one stereotype, and TOU curiosity still does not replace the statement. PG&E, SCE, SDG&E, munis, and CCAs are different rulebooks; we will not invent an export-rate headline. Ballpark from your bill first; installer confirms the meter.

PSPS is not a solar feature

Wildfire season and public-safety shutoffs make backup a real question for some households. Grid-tied panels shut down when the grid is down. More modules do not keep the house on during a PSPS event. Size from usage; treat storage as its own decision.

If shutoffs are why you’re looking, skim /batteries after you size from the bill — panels alone aren’t backup. Battery basics.

Helio estimate vs installer quote

Helio is the homework. You leave with a system size, a production sketch, and a cost range so a sales visit is not the first time you have seen the numbers. That is a ballpark.

An installer quote is after a site survey: roof, electrical panel, setbacks, utility paperwork, and the equipment they will actually hang. Those details can raise or lower the number. That is the bid.

Does time-of-use change how I should size rooftop solar?

TOU can change when your usage is expensive, but system size still starts from the kilowatt-hours you buy and what the roof and utility rules allow. We won’t invent a California export-rate table. Your installer confirms the account.

Helio does not invent ¢/kWh or $/W as statewide facts. Your bill and installer confirm what applies to your meter.
