405W Residential Solar Panels by the Pallet
The Seraphim 405W solar panel is a Tier 1 monocrystalline PERC module with 108 half-cut cells, 20.7% efficiency and a clean all-black look. It’s sized for residential rooftops and sold here as a full pallet of 36 panels, giving you 14.58kW of DC capacity at wholesale pricing. With a 15-year product warranty and a 25-year linear power warranty, it’s built to deliver dependable output for decades.
The 400-watt class has become the standard for home solar, and for good reason. At about 5.6 ft by 3.7 ft, a 405W panel packs strong output into a size that fits most roofs, racking systems and installer workflows. So whether you’re installing a single home system, several residential jobs or a ground-mount array, a pallet of Seraphim 405W panels gives you matched modules at a lower cost per watt. Better still, it ships free from our Houston, Texas warehouse, usually within 2 days.
Key Features
405W Mono PERC With 108 Half-Cut Cells
Half-cut 182mm PERC cells reduce internal resistance and split the panel into two independent halves. As a result, shade on one part of the panel costs less power, and the module runs cooler and more efficiently.
All-Black Module for Residential Roofs
The black finish blends into dark roofing for a clean, low-profile look that homeowners and HOAs prefer. It’s a popular choice for street-facing roofs where appearance matters as much as output.
Strong Low-Light and Heat Performance
Optimized PERC cells keep producing in cloudy weather, early mornings and late afternoons. A -0.34%/°C power temperature coefficient also limits losses on hot summer days.
Built for Snow and Wind Loads
The panel is rated for 5,400 Pa of front-side snow load and 2,400 Pa of rear-side wind load. On top of that, 3.2mm anti-reflective tempered glass, an anodized aluminum frame and an IP68 junction box with 3 bypass diodes protect it in harsh weather.
Triple EL Tested and Certified
Every module goes through three electroluminescence (EL) inspections to screen out micro-cracks. Seraphim manufactures under ISO 9001, ISO 14001 and ISO 45001, and the panel carries UL, CSA, CEC, TÜV, CE and PV CYCLE certifications for US and international projects.
What’s on One Pallet
- 36 panels × 405W = 14.58kW of DC capacity
- About 1,706 lb (774 kg) of panels, before packaging
- Matched panels from one production batch for consistent string performance
- 23 pallets per 40ft container (828 panels) for US project orders
A full pallet arrives by freight, so plan for a forklift or liftgate delivery. Our team can arrange liftgate service if your site needs it.
How Many 405W Panels Do You Need?
To size a home system, divide your daily energy use by your local peak sun hours, then divide by about 0.32kW of real-world output per panel. For example, the average US home uses about 29kWh per day. With 5 sun hours, that works out to:
29 ÷ 5 ÷ 0.32 ≈ 18–19 panels (about 7.5kW)
| System size | Number of 405W panels | Typical fit |
|---|---|---|
| 4kW | 10 | Small home or cabin |
| 7.5kW | 18–19 | Average US home |
| 10kW | 25 | Large home or home with EV |
| 14.58kW | 36 (one pallet) | Very large home, farm or two smaller homes |
Inverter Compatibility and String Sizing
With 12.97A operating current and 13.86A short-circuit current, the Seraphim 405W works with most modern string inverters, hybrid inverters, microinverters and optimizers rated for 14A or higher inputs.
For string sizing, the 37.25V open-circuit voltage rises in cold weather. Here’s how many panels fit in series at around -10°C (14°F):
| Inverter max DC voltage | Max panels per string |
|---|---|
| 500V | 12 |
| 600V | 14 |
| 1,000V | 24 |
Always calculate with your site’s record low temperature. For a complete home system, pair these panels with a Sol-Ark hybrid inverter or a LuxPower hybrid inverter, and add residential battery storage for backup power.

Frequently Asked Questions
How much power does a 405W solar panel produce per day?
In a location with 5 peak sun hours, one 405W panel typically produces about 1.6kWh per day after real-world losses. A full pallet of 36 panels produces roughly 55–65kWh per day, depending on orientation, shading and climate.
Is a 405W panel good for residential solar?
Yes. At about 5.6 × 3.7 ft and 47 lb, the 405W format fits most residential roofs and racking systems. It’s one of the most common panel sizes for home solar installations in the US.
Are Seraphim solar panels Tier 1?
Yes. Seraphim is recognized as a Tier 1 solar manufacturer, a rating that reflects production scale, financial strength and bankability.
How does the Seraphim 405W compare with other 405W panels?
Most Tier 1 405W half-cut panels, including models from JA Solar, Jinko Solar and Canadian Solar, use a similar 108-cell, 182mm format with comparable dimensions. That makes the Seraphim 405W easy to fit into standard residential racking and system designs.
Does this panel work with microinverters?
Yes, with most modern microinverters. Its 12.97A operating current and 13.86A short-circuit current fall within the input range of most current microinverters and optimizers, but always confirm against your equipment’s specs.
