400W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
400W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop
Four hundred watts from one module means fewer panels, fewer roof penetrations and less railing for the same array output. On a residential rooftop that translates directly into lower mounting hardware cost per installed kilowatt.

- Commercial rooftops needing high watt density per square metre
Questions buyers ask
Is a heavier module harder to install?
At 20.4 kg it is a two-person lift. The mechanical load rating of 5400 Pa on the front side is unchanged, so the roof structure, not the glass, is usually the limiting factor.
What inverter pairing makes sense?
Match the string voltage to a string inverter or MPPT with adequate headroom, and have your installer confirm the cold-temperature open-circuit voltage stays inside the inverter's limit.

Frequently Asked Questions
What is a monocrystalline solar panel?
A panel built from single-crystal silicon cells, giving higher efficiency and a smaller footprint than polycrystalline types.
Do panels work on cloudy days?
Yes, at reduced output — typically 10–50% of clear-sky levels depending on how thick the cloud cover is.
How long do solar panels last?
Quality modules commonly retain most of their output for 20–25 years thanks to tempered glass and aluminium frames.
Can I connect panels to a battery?
Panels feed an MPPT charge controller or hybrid inverter, which safely charges the connected battery bank.
