High-Efficiency Monocrystalline Solar Panels for Residential Roofing
In today's competitive renewable energy market, balancing performance with solar panels for house roof cost is paramount for installers and distributors. Our 400W Monocrystalline PERC Solar Panel is engineered to deliver superior energy yield and long-term reliability, maximizing the return on investment for every residential installation. Designed with cutting-edge technology, these panels ensure optimal performance even in low-light conditions, making them an ideal solution for diverse residential rooftops.
Product Overview
This 144-cell monocrystalline solar module represents the next generation of residential photovoltaic technology. By incorporating advanced PERC (Passivated Emitter and Rear Cell) design and half-cut cell technology, it achieves higher efficiency ratings and lower degradation rates than conventional panels. This translates directly into more power per square meter, a critical factor when calculating the overall system solar panels for house roof cost and long-term energy savings for the end-user. Its robust construction and sleek, all-black aesthetic seamlessly integrate into modern residential architecture.
Key Features
- High-Efficiency Monocrystalline PERC Cells: Achieves conversion efficiencies over 21%, ensuring maximum power output from limited roof space.
- Half-Cut Cell Technology: Reduces internal resistance and minimizes shading losses, increasing energy harvest by up to 3%.
- Enhanced Durability: Features anodized aluminum frame and high-transmission, anti-reflective tempered glass capable of withstanding high wind (2400Pa) and snow loads (5400Pa).
- Excellent Low-Light Performance: Superior performance during early morning, late evening, and overcast days, guaranteeing consistent energy production.
- 12-Year Product Warranty & 25-Year Linear Performance Warranty: Backed by industry-leading guarantees, ensuring peace of mind and protecting the client's investment.

Frequently Asked Questions (FAQ)
What is the typical price range for these panels in a residential system?
As a manufacturer, we provide competitive FOB or CIF pricing to our B2B partners. The final installed solar panels for house roof cost for the end-user depends on several factors your company manages, including local labor, permitting, inverter choice, and mounting hardware. Our high-efficiency panels help you lower the overall system cost by reducing the number of units and balance-of-system components required.
How does panel efficiency affect the total system cost?
Higher efficiency directly reduces balance-of-system (BOS) costs. With more power per panel, you need fewer panels, less racking, fewer connectors, and reduced installation labor to achieve the same system capacity. This optimization is crucial for managing the total project solar panels for house roof cost and improving your project margins.
Do you provide technical support for system design?
Yes. We offer comprehensive technical support to our partners, including detailed datasheets, I-V curve data, and compatibility guidance. Our engineering team can assist with preliminary system layout consultations to ensure optimal performance of our products in your specific installations.
What are the payment and shipping terms?
We offer flexible terms including T/T and LC. Shipping can be arranged via sea freight (FCL/LCL) or air freight based on your urgency and volume. All products are professionally packed to prevent transit damage.
Can the panels be used with all major inverter brands?
Absolutely. Our panels have standard electrical parameters and are compatible with all major grid-tied inverter brands (e.g., SMA, Fronius, Huawei, Sungrow, Enphase). We provide the necessary electrical specifications to ensure seamless integration with your chosen system components.
