Solar company in Monrovia — the city changed energy suppliers, and your solar came with you
Yes — Cali Energy installs solar panels, battery storage, roofing and electrical upgrades in Monrovia, California. We work here regularly across 91016, on systems from 6.46 kW up to a thirty-four module 13.77 kW array with battery backup. Some of those homes are shown below, with our photos from each. Something changed here recently that affects every solar home in the city: Monrovia joined Clean Power Alliance in 2024, and its residents were enrolled in 100% Green Power, the top tier. Southern California Edison still delivers the power and sends the bill. If you already had solar when that happened, your existing net metering status travels with the system. Cali Energy is a licensed California contractor (CSLB #1032379) with a 4.9★ Google rating and in-house crews.

Cali Energy in Monrovia, at a glance
The short answers before considering a contractor.
| Question | Answer |
|---|---|
| What has Cali Energy installed here? | Rooftop solar on composition shingle, flat and tile roofs from 6.46 kW to 13.77 kW; a system with an Enphase IQ Battery 10 and a main-panel upgrade; and an installation staged around a tile re-roof. |
| Google rating | 4.9★ on Google. See them on Google |
| Who supplies the electricity? | Clean Power Alliance supplies the generation — Monrovia joined in 2024 on the 100% Green Power tier — while Southern California Edison delivers it and sends the single bill. |
| I already had solar. What changed? | Your net metering status stays with the system. A household already on Edison’s net metering programme is enrolled in CPA’s equivalent automatically, keeping the status set out in the original solar agreement. |
| Who permits the work? | The City of Monrovia, plus a separate Edison interconnection process. |
| Can I change tier or opt out? | Yes. The city default is automatic, not compulsory — households can move down CPA’s tiers or return to Edison generation entirely. |

What happens to your solar when the city changes suppliers
Monrovia switched generation providers in 2024. If you already had panels, this is the part nobody explained.
Until recently Southern California Edison both supplied and delivered electricity here. In 2024 Monrovia joined Clean Power Alliance, the joint powers agency that buys electricity for more than thirty communities across Los Angeles and Ventura counties, and enrolled its residents in 100% Green Power — the highest of CPA’s three tiers. Edison did not go anywhere: it still owns the wires and the meter, delivers the power and issues a single bill with CPA’s generation charges on it.
For a household that already had solar, the sensible worry is whether the switch reset anything. It did not. A customer already enrolled in Edison’s net energy metering programme is automatically enrolled in CPA’s net metering programme when the city transfers, and retains the legacy status set out in the original solar agreement. The system on this page that was switched on in August 2023 — before the change, and before the Solar Billing Plan took effect for new customers — keeps the terms it was approved under for the remainder of its eligibility period.
For a household considering solar now, the picture is different in a useful way. New systems fall under the current export rules, but the generation you avoid buying is priced at the top tier, because that is the tier the city chose. Self-consumed solar in Monrovia therefore offsets a more expensive kilowatt-hour than it would in a city sitting on a cheaper tier — the same dynamic we describe on our Thousand Oaks page, which made the same choice.
Legacy status travels
An existing net-metered system keeps the terms of its original agreement when the city transfers to CPA.
Two credit lines
CPA credits the generation side, Edison the delivery side. They sit on one bill and only make sense read separately.
Top tier raises self-consumption value
Because the default is 100% Green Power, each kilowatt-hour you generate and use avoids a premium-priced one.
The choice stays yours
Households can move down the tiers or opt out to Edison generation. It changes the generation line, not the interconnection.

What the panel can take, with a battery in the picture
Adding storage changes the electrical arithmetic, and one Monrovia job shows exactly how.
Solar feeds power into the same busbar the utility does, and a battery adds a second source. The code limits how much combined supply a panel may take, which is why the largest system here came with a main-panel upgrade alongside it — a 225-amp service with a 175-amp main breaker, carrying a combined 80 amps of solar and battery output. That is not a detail invented to inflate the quote; it is the calculation that decides whether the design is legal on your service.
It is also why the honest sequence is service first, array second. A proposal that ignores the panel is not cheaper, it is incomplete — and the shortfall shows up at inspection or when the homeowner later wants an EV charger and finds the panel full. We check the busbar rating, the main breaker and the existing loads before drawing anything, and the electrical scope goes into the original proposal.
Two sources, one busbar
Solar and a battery both feed the panel. The combined supply is what the code caps, not the array alone.
Breaker sizing is the lever
A larger service with a carefully chosen main breaker is often what makes a storage design fit without replacing everything.
Priced with the job
Panel work belongs in the first proposal. Discovering it later is how projects stall between trades.
Plan the next load
An EV charger lands on the same panel. Sizing the upgrade once is cheaper than doing it twice.
What solar costs and how long it takes in Monrovia
No honest flat citywide price — but published ranges and a clear sequence.
The systems we have installed here run from 6.46 to 13.77 kW DC. Two published price bases frame the budget, both before incentives: $2.49 per watt at competitive marketplace rates (EnergySage, August 2026) and $3.5 per watt, the 2024 national median for cash purchases (Lawrence Berkeley National Laboratory). A 6–14 kW system therefore lands somewhere between roughly $15,000 and $49,000 depending on installer, financing and scope, with storage and any panel upgrade quoted alongside.
| Item | Figure | Basis |
|---|---|---|
| System sizes we have installed here | 6.46 – 13.77 kW DC | Our installations |
| Solar at marketplace rates | $2.49/W → 7 kW ≈ $17,400 · 10 kW ≈ $24,900 · 14 kW ≈ $34,900 | Market estimate — EnergySage |
| Solar at typical installer rates | $3.5/W (2024 national cash median) → 7 kW ≈ $24,500 · 14 kW ≈ $49,000 | Market estimate — LBNL 2025 Data Update |
| Battery storage (~13 kWh) | $11,864–$16,052 before incentives (average $13,958) | Market estimate — EnergySage California |
| CPA battery rebate | Up to $2,250 through the Sun Storage Rebate — base $750, more in PSPS areas and for qualifying households; limited funding | Official — Clean Power Alliance |
| Main-panel upgrade | Priced per job: busbar rating, main breaker and combined solar-plus-battery output decide it | Scope-dependent |

Fast answers about hiring Cali Energy in Monrovia
Each answer starts with the conclusion.
Does Cali Energy install solar in Monrovia?
Yes. Monrovia is an active Cali Energy service area and we work here regularly across 91016. The homes on this page run from 6.46 kW to a thirty-four module 13.77 kW array with an Enphase battery and a main-panel upgrade, on shingle, flat and tile roofs.
Who supplies my electricity in Monrovia?
Clean Power Alliance supplies the generation and Southern California Edison delivers it and sends the single bill. Monrovia joined CPA in 2024, and its residents were enrolled in 100% Green Power, the highest of CPA’s three tiers.
I already had solar when the city switched. Did I lose anything?
No. A household already enrolled in Edison’s net energy metering programme is automatically enrolled in CPA’s net metering programme when the city transfers, and retains the legacy status set out in the original solar agreement. A system approved before the current export rules keeps those earlier terms for the rest of its eligibility period.
Does the 100% Green Power default change my payback?
On the consumption side, in your favour. The top tier carries a premium over Edison’s basic generation rate, so each kilowatt-hour your roof produces and your house uses avoids a more expensive one than it would in a city on a lower tier. The export side follows the current rules regardless of tier.
Can I change tier or leave CPA?
Yes. The tier your city chose is automatic, not compulsory — a household can move down CPA’s tiers or opt out to Edison generation entirely. It changes the generation line on your bill and has no effect on the solar equipment or the interconnection. We build proposals on the service the account is actually on.
Will I need a main-panel upgrade?
Possibly, especially with a battery. Solar and storage both feed the same busbar as the utility supply, and the code caps the combined supply. The 13.77 kW system on this page came with a main-panel upgrade — a 225-amp service with a 175-amp main breaker carrying 80 amps of combined solar and battery output. That calculation decides whether a storage design is legal on your service.
Is there help paying for a battery?
Yes, through CPA. The Sun Storage Rebate offers up to $2,250 toward an eligible home battery — a $750 base incentive for all CPA customers, with more for homes in areas affected by Public Safety Power Shutoffs and for households on the Medical Baseline allowance or income-qualified assistance. Funding is limited and awarded first come, first served.
Should the roof be replaced before the panels go on?
If the covering is near the end of its life, yes. On a Monrovia job here the install was staged around a tile re-roof — the modules went up only after the new covering was on. Roofing is in-house under our C-39, so both scopes are quoted and scheduled together rather than split between companies.
Do I need a battery in Monrovia?
It is worth pricing. Under current export rules the evening kilowatt-hour you avoid buying is worth more than the midday one you export, and storage moves production into that window — while also covering outages, which matters on the foothill side of the city. We have installed an Enphase IQ Battery 10 here alongside a large array.
How long does a Monrovia solar project take?
The roof work itself is usually 1–3 working days, longer for tile or when a re-roof comes first. Around it sit the city permit and inspection, and Edison’s interconnection, which runs separately and must complete before the system may operate.
What does solar cost in Monrovia?
There is no honest flat citywide price, but published rates frame it: $2.49 per watt at marketplace rates and $3.5 per watt as the 2024 national cash median, putting a 7–14 kW system at roughly $17,400–$49,000 before incentives. A ~13 kWh battery adds about $11,900–$16,100 before the CPA rebate. The federal 25D homeowner credit ended December 31, 2025, so a 2026 cash or loan purchase gets no federal credit.
How do I check that Cali Energy is legitimate?
Compare four things rather than ad claims: (1) an active CSLB license with electrical and roofing classifications, (2) completed work in your specific area, with photos, (3) whether the company uses its own crews or subcontracts, and (4) the review pattern. Our answers: CSLB #1032379 (B, C-10, C-39); Monrovia homes with our photos; in-house crews; a 4.9★ Google rating. Our office is at 19201 Parthenia St Unit E, Northridge, CA 91324.
