Requesting an assessment does not commit you to anything
Local conditions
Three things about Fremont that change how a system should be designed
Eligible systems can receive an Instant Solar Permit through Fremont’s SolarAPP+ process. Fremont runs an Instant Solar Permit program on the SolarAPP+ platform. A roof-mounted system that meets the eligibility checklist, with or without a battery and including a main electrical service upgrade, can have its permit issued automatically once the required documents are uploaded and the $25 SolarAPP+ processing fee and applicable permit fees are paid. Two details matter here: only contractors registered with SolarAPP+ can use it, and the city’s inspection fee covers two inspections of the same element. If additional inspections are required, re-inspection fees apply.
Your electricity comes from two companies. Generation and delivery sit with different providers, and they respond differently once panels go on the roof. After a June 2024 City Council vote, most Fremont residential customers transitioned to Ava Community Energy’s Renewable 100 plan in August 2025 as the default electricity generation service. Customers on certain discount programs, including CARE and FERA, may have different default service. California’s Net Billing Tariff (often called NEM 3.0) generally provides lower compensation for exported solar energy than the older NEM 2.0 tariff.
Both belong in the design from day one.
The bill has been restructured, not just cut. PG&E lowered residential rates on 1 March 2026 for the fifth time since early 2024, and says bundled residential rates are now about 13% below January 2024. The same change introduced a Base Services Charge of roughly $24 a month for standard residential accounts. That fixed charge does not fall when you generate more. Solar only works on the energy portion of the bill, and in 2026 that puts the emphasis on using your own power in the evening, with a battery to hold it until then.
Fremont, by the numbers
Four figures worth checking before you sign anything
Figures above are set by the City of Fremont, PG&E and Ava Community Energy and were current in September 2026. Permit fees, rates and tariffs change; confirm current amounts with each provider before making a decision.
Everything, in-house
Seven services, one crew, no subcontractors
Most Fremont homeowners call about panels. The jobs that go smoothly are usually the ones where the electrical panel, the battery and the car charger were planned at the same time as the roof. Nabu staff handle all seven of these.
Solar PV design and installation
Rooftop systems for homes and commercial buildings, sized from a year of your actual PG&E usage. We install REC and HD Hyundai panels and choose microinverters or a string inverter based on the roof, its shading and your budget.
Home battery storage
Tesla Powerwall, Enphase and LG batteries. Under California’s Net Billing Tariff (often called NEM 3.0), a battery can store daytime solar generation for later use during higher-value evening hours. When configured for backup, battery storage can also provide power to selected essential loads during an outage, subject to system design, available capacity and operating conditions.
EV charging stations
Level 2 home chargers, including the dedicated circuit and any panel work involved. Plenty of Fremont garages were wired decades before anyone parked an EV in one.
Main service panel upgrades
Existing 100A electrical service may have limited capacity for adding solar, battery storage and EV charging. We evaluate the existing service and determine whether an upgrade is required.
Solar uninstall and reinstall
If a roof replacement requires temporary solar removal, we can coordinate removal, secure storage and system reinstallation after the roofing work is complete. Roof penetrations and mounting components are addressed as appropriate to the roofing system, project scope and applicable manufacturer requirements.
Equipment RMA and replacement
When covered equipment requires warranty service, we can coordinate the manufacturer’s RMA process and, where applicable, coordinate repair or replacement in accordance with the manufacturer’s warranty terms.

Why us
Why Fremont homeowners choose us for solar panel installation
Nobody in the price is paid to close you
A commissioned salesperson’s cut is built into many solar quotes. We do not employ any, and the difference shows up in what you pay for panels, inverters and labor.
The people who quote it stay involved through installation
Design, permitting and installation are done by Nabu employees. Ask any installer who will physically be on your roof; the answer tells you a lot about how the job will go.
Permitting is handled, whichever route applies
Fremont offers an Instant Solar Permit process for eligible rooftop solar and storage projects, while other projects follow the applicable permit-review process. We evaluate the project requirements and prepare and submit the appropriate application.
Designed for the Net Billing Tariff, not for 2019
California’s Net Billing Tariff changed how excess solar generation is credited compared with older NEM programs. We consider your household’s energy use, applicable utility rates, solar production and battery storage needs when designing the system.
Certified by the manufacturers
Our team maintains applicable manufacturer certifications for the equipment we install, including Tesla Powerwall, REC, Enphase and SolarEdge, where applicable. Manufacturer warranty requirements vary by product, so we follow the applicable installation and warranty requirements for each system.
If the site is not a good fit
If the roof is heavily shaded, appears due for replacement, or the available usage information does not support the investment, we will tell you what we find. A system that disappoints you is bad for both of us.
The process
What a Fremont installation looks like, stage by stage
Project timing depends on the property, system design, permitting, utility requirements and other project-specific factors. We provide a project timeline after the assessment.
Assessment
We review a year of PG&E and Ava bills, inspect the roof and the main panel, and ask what else is on the horizon, such as an EV, a heat pump or an ADU. Requesting an assessment does not commit you to anything.
Design and proposal
You receive a proposal with the major system components identified and pricing clearly presented. We do not use artificial expiration dates or high-pressure sales tactics.
Permitting and utility paperwork
We prepare and submit the applicable Fremont permit application, including the Instant Solar Permit process for eligible projects, and coordinate the PG&E interconnection application.
Installation by our own crew
Our crew installs the system we designed. Dates are confirmed with you in advance.
Inspection and interconnection
The city inspects, then PG&E grants permission to operate. Their timelines are outside our control, and we keep you updated on where things stand.
Commissioning and monitoring
We commission the system, set up monitoring on your phone and walk you through it. After that, service questions come to the same office.
Paying for it
Three ways to pay, and what 2026 changed
The cost of solar panel installation in Fremont depends on factors such as roof size and shape, energy usage, system size, whether battery storage is included and whether electrical upgrades are needed. A preliminary estimate can change after the property and available utility usage information have been reviewed.
The federal picture has changed. Under federal law as of September 2026, the Residential Clean Energy Credit under Section 25D is not available for qualifying expenditures made after December 31, 2025. Federal tax law is subject to change. Homeowners should consult a qualified tax professional regarding their individual circumstances. Certain third-party-owned solar arrangements may have different federal tax treatment because the system owner, rather than the homeowner, may be the party eligible for applicable business tax incentives. Eligibility and treatment depend on the specific structure and applicable tax rules. Nabu does not provide tax advice. Consult a qualified tax professional regarding your individual circumstances. Be cautious of outdated tax-credit information when comparing solar proposals. Verify current federal tax rules with IRS.gov or a qualified tax professional.

Questions
The Fremont questions that come up on the phone
How long does a solar permit take in Fremont?
For an eligible rooftop system, the Instant Solar Permit can be automatically issued through Fremont’s SolarAPP+ process. Fremont’s Instant Solar Permit program runs on SolarAPP+: once the required documents are uploaded and the $25 SolarAPP+ processing fee and applicable permit fees are paid, the permit can be automatically generated for eligible projects, provided the contractor is registered with SolarAPP+. Systems outside the eligibility checklist follow the city’s applicable standard permit-review process.
Is solar still worth it in Fremont under California’s Net Billing Tariff (NEM 3.0)?
It can be, provided the system is designed around California’s current rules. California’s Net Billing Tariff (often called NEM 3.0) generally provides lower compensation for exported solar energy than the older NEM 2.0 structure, which increases the importance of using solar energy on-site. For some Fremont homes, that can make battery storage worth considering, particularly when the system is designed around evening energy use. A system modeled using outdated NEM 2.0 compensation assumptions may not accurately reflect the economics of a system under today’s rules.
I am on Ava Renewable 100. Can I still install solar?
Yes. Ava Community Energy provides generation service, while PG&E continues to provide delivery service and maintains the electric meter. Solar interconnection and billing arrangements depend on the applicable utility and program requirements. We review your available utility billing information when designing the system rather than relying on a rule of thumb.
Do I need to upgrade my electrical panel?
Sometimes. An older or smaller electrical service may require an upgrade depending on the existing load, proposed solar and battery system, EV charging equipment, and other electrical requirements. We evaluate the electrical service during the assessment. For eligible projects, Fremont allows certain main electrical service upgrades to be included with an Instant Solar Permit application.
What does solar panel installation cost in Fremont?
Roof size and shape, how much of your electricity usage you want to offset, whether battery storage is included, and whether electrical upgrades are needed can all affect project cost. We provide a preliminary estimate and refine pricing after reviewing your property, system requirements, and available utility usage information. Nabu does not use commissioned salespeople.
Why are you not the cheapest quote I have?
Price differences can reflect differences in system design, equipment, labor, electrical work, permitting, warranties, and project scope. When comparing proposals, make sure you are comparing the same system size, equipment, installation scope, electrical upgrades, and included services.
Can I still claim the 30% federal tax credit?
The federal Residential Clean Energy Credit under Section 25D is not available for qualifying residential clean-energy expenditures made after December 31, 2025. Tax treatment of leases, PPAs, and prepaid solar agreements can differ because the system owner and transaction structure may determine which federal tax provisions apply. Eligibility depends on the specific arrangement and applicable tax rules. Homeowners should consult a qualified tax professional regarding their individual situation.
What happens if a panel or inverter fails later?
If covered equipment develops a problem, we can help coordinate the applicable manufacturer RMA or warranty process. Repair or replacement depends on the equipment, diagnosis, warranty terms, and manufacturer requirements. Manufacturer warranty requirements vary by product, so we follow the applicable installation requirements and warranty procedures for each system.
