What Is Axia by QCells?
Axia by QCells was created by Hanwha to give homeowners a direct, consistent path from the QCells factory to their roof. Rather than supplying panels to a wide variety of contractors with varying quality standards, Axia brings the full system — panels, battery, inverter, and installation — under one manufacturer's roof.
This means every component in your system is engineered by QCells to work together. Installation, warranties, monitoring, and support all come from the same source. There is no finger-pointing between manufacturers and no mismatched equipment. One system, one warranty, one point of accountability.
QCells has been a leader in global solar innovation since 1999 and is backed by the Hanwha Group, a Fortune Global 500 company. That financial stability means your 25-year warranty is backed by a company with the resources to honor it.
QCells Solar Panels — Made in the USA
QCells manufactures its premium monocrystalline solar panels in Dalton, Georgia — home to the largest solar panel factory in the Western Hemisphere. Producing over 60,000 panels a day, the facility gives homeowners the confidence of domestic manufacturing, a secure supply chain, and a company deeply committed to the US solar market.
High-efficiency monocrystalline technology QCells panels use advanced cell technology that delivers strong performance across a wide range of light conditions — including the morning fog and seasonal overcast skies common across Santa Clara and San Mateo Counties.
Q.TRON panels — maximum output For homeowners who want the highest output available, the Q.TRON line offers maximum efficiency in a standard panel footprint. Ideal for homes with limited roof space that need to maximize energy production.
25-year product and performance warranty Every QCells panel comes with a 25-year product and performance warranty backed by Hanwha. The warranty covers both equipment defects and long-term energy production levels.
Wind and weather rated QCells panels are rated for high wind loads and tough weather conditions, making them well suited for Bay Area homes that experience strong seasonal winds, coastal moisture, and heat.
Qcells’ 300,000 sq ft factory in Dalton, GA produces over 60,000 solar panels a day—proudly made in the USA.
Inverters and System Components
Axia systems include QCells-approved inverters engineered for efficiency, reliability, and easy monitoring. Hybrid inverter options are available for homeowners who want to add battery storage now or plan to add it in the future without modifying the rest of the system.
Real-time energy monitoringThe system gives you full visibility into your energy production and consumption through an integrated monitoring platform. You can see exactly how your system is performing at any time.
Hybrid inverter optionChoosing the hybrid inverter at installation makes adding a battery straightforward — no additional equipment changes required when you are ready to expand.
25-year inverter warrantyInverter coverage is included under the Axia warranty structure, backed by QCells and Hanwha.
Q.HOME CORE Battery Storage — Backup Power and NEM 3.0 Savings
Q.HOME CORE battery from Qcells—store solar energy for backup power and peace of mind.
Pairing your Axia solar system with a Q.HOME CORE battery creates a complete home energy solution. Under California's NEM 3.0 rate structure, battery storage is essential for maximizing the value of your solar investment. PG&E pays significantly less for solar energy exported to the grid during the day — a battery captures that energy and makes it available when electricity rates are highest in the evening.
The Q.HOME CORE G3 is the latest generation of QCells' residential battery, now manufactured domestically in Michigan and domestic-content eligible for tax credit purposes.
Safe LFP chemistryThe Q.HOME CORE uses lithium iron phosphate (LFP) chemistry — known for long cycle life, thermal stability, and safety.
Scalable capacityThe system is modular, scaling from 10 kWh up to 20 kWh to match your home's energy needs.
Backup power during outagesThe Q.HOME CORE provides seamless backup during PG&E outages and planned shutoffs, keeping your essential systems running.
Integrated monitoringManaged through the Q.OMMAND app, giving you real-time visibility into storage levels, energy flows, and system performance.
One manufacturer, one warrantyThe Q.HOME CORE battery is covered under the same Axia warranty structure as your panels and inverter — one system, one warranty, one point of contact for support.
Add an EV Charger to Your Axia Project
If you drive electric or plan to, adding a Level 2 EV charger at the same time as your solar installation is the most cost-effective approach. The electrical work is already underway and adding a charger during the project eliminates a separate mobilization cost. Home Pro coordinates EV charger installation as part of your overall project. Learn more about EV charger installation.
