ChenXin 400W Monocrystalline Solar Panel — High-Efficiency Energy Harvest
The ChenXin 400W Solar Panel is a premium monocrystalline PERC module built to pair perfectly with ChenXin battery systems — or any major inverter — for a complete solar-plus-storage setup. With 21.3% conversion efficiency, it harvests more energy per square metre than standard panels, which means fewer modules, less roof space and faster payback.
Durability is engineered in: tempered low-iron glass, a corrosion-resistant aluminium frame and an IP68 junction box withstand 2400Pa wind loads, 5400Pa snow loads and hail impact. A 25-year performance guarantee (92% output at year 25) and 12-year product warranty protect your investment for decades.
Sold individually or as part of a full ChenXin solar kit, each panel is quality-tested before shipping and delivered worldwide. Add one to a portable power station for off-grid adventures, or array several on a rooftop to charge a 5kWh–20kWh home battery every sunny day. Browse solar-compatible systems →

Frequently Asked Questions
How many 400W panels do I need for a home battery?
For a 5kWh battery, 2-3 panels provide sufficient daily charging. For 10kWh, we recommend 4-6 panels. For 20kWh, 8-12 panels are ideal. The exact number depends on your location's sunlight hours and energy consumption.
Are these panels compatible with all battery systems?
Yes, ChenXin 400W monocrystalline panels use standard MC4 connectors and work with all major charge controllers and inverters. They are compatible with any 48V battery system, including non-ChenXin brands.
What is the efficiency rating of the 400W panel?
The ChenXin 400W monocrystalline panel has a module efficiency of 21.3%, which is above the industry average of 18-20%. It performs well in low-light conditions and has a temperature coefficient of -0.35%/°C.
How long do these solar panels last?
ChenXin 400W panels come with a 25-year linear power output warranty, guaranteeing at least 80% of rated output after 25 years. The expected service life is 30+ years with minimal degradation.
Do the panels withstand harsh weather?
Yes. The panels are certified to withstand wind loads up to 2,400 Pa (approximately 130 mph), snow loads up to 5,400 Pa, and 25mm hail at 23 m/s. They have an IP68-rated junction box for water and dust resistance.
