Three companies gave us monthly payments. Daylight gave us a one-page sheet with the actual system price, the loan terms, and the payback math — before anyone came to the house. That's why they got the job.
Main Electrical Panel Upgrades — 200-Amp Service for Solar, Batteries & EVs
A lot of Inland Empire homes — especially the 1960s–1980s housing stock in Riverside, San Bernardino, and Fontana — still run 100-amp main panels. Add central AC, an EV charger, a battery, and an induction range, and that panel becomes the bottleneck for everything you want to do next. A 200-amp upgrade is the unglamorous foundation under every other electrification project, and it's the item most solar quotes conveniently forget to mention until after you've signed.

Main Panel Upgrade in the Inland Empire
A lot of Inland Empire homes — especially the 1960s–1980s housing stock in Riverside, San Bernardino, and Fontana — still run 100-amp main panels. Add central AC, an EV charger, a battery, and an induction range, and that panel becomes the bottleneck for everything you want to do next. A 200-amp upgrade is the unglamorous foundation under every other electrification project, and it's the item most solar quotes conveniently forget to mention until after you've signed.
Quoted Up Front, Not Discovered Later
If your project needs a panel upgrade, it's in the initial written price. A four-figure 'discovery' after signing is a classic of the genre — not ours.
Utility Coordination Handled
Panel upgrades mean coordinating a service disconnect with SCE (or RPU) and a city inspection. We run that calendar so you don't.
Room to Grow
We spec breaker space for what's next — the second EV, the battery expansion, the ADU — so the panel you buy once is the last one you buy.
Code-Current Safety
Modern panels bring modern protection: proper grounding, AFCI/GFCI where code requires, and no more scorched fuse-era guesswork behind the cover.

Why homeowners choose Daylight
Consistently praised for written prices that don’t move, designs that match the utility actually billing the home, and clean, on-schedule installs — with straight answers even when the answer is “don’t buy solar yet.”

Our SCE bill was hitting $480 in July. The battery design covers our whole 4–9pm window now and the install crew was clean, on schedule, and walked me through the monitoring app before they left.

Honest company. They told my mother solar did NOT make sense on her small bill and fixed her orphaned system's inverter instead. Who does that? These guys.

We're in Riverside city on RPU and they actually knew what that meant — designed solar-only, no battery upsell, because our export credits are different. Every other quote tried to sell us storage we didn't need.

Panels plus a new roof in one project in Menifee. One crew, one warranty conversation, no finger-pointing. The paperwork was large print and plain English, exactly like they promise.

EV charger and panel upgrade quoted up front with the solar — no surprise change orders halfway through. System's been producing right at the modeled numbers all summer.
Main Panel Upgrade — Common Questions
If your home is pre-1990 and still on its original 100-amp panel, it's worth a look before any solar, battery, or EV project. A load calculation gives the real answer. Certain legacy brands with documented failure histories also earn an automatic recommendation to replace.
The install itself is typically a day, with a planned power shutoff of several hours. The calendar time is mostly permitting and utility scheduling, which we manage — expect a few weeks end to end depending on the city.
