Key features

The panel keeps first year power attenuation below 1%, with only 0.4% linear power loss each year afterwards to meet 30-year warranty standards

All cells have passed 2000 hours PID test and anti-LID inspection, so no power drop caused by voltage and sunlight influence

We strictly control power range from 0 to +5W and classify every panel separately without mixing different power grades

The glass adopts double-sided AR coating with light transmittance reaching 94.5% and performs well under weak sunlight conditions

The 6063-T5 frame has finished 1000 hours salt spray testing so it can resist corrosion in coastal and high humidity regions

Third-party institutions tested the module under IEC standards, which can bear 5400Pa snow pressure and 2400Pa wind force

Three independent bypass diodes are built inside IP68 junction boxes to effectively avoid permanent damage from hot spots

It supports 1500V high voltage connection which helps clients save cable cost during large solar farm construction

Product Q&A

Q:Are these panels made of brand new A-grade cells?

All modules use brand new original A-grade cells. Every panel will do full EL inspection and flash test one by one, no broken cells or recycled wafers inside.

Q:Do you strictly sort power without mixing bins?

We make strict control for power tolerance from zero to plus five watts. All goods will be sorted carefully, and we will never put panels of different power levels into one container.

Q:Are your certificates valid for customs clearance?

All certificates are original TUV & IEC approvals. We can provide batch test reports matched with each shipment for local customs inspection.

Q:What is the exact power attenuation standard?

The power loss of our solar panels will be controlled within one percent in the first year. After that, the annual linear power decay will be only zero point four percent every year. We can provide official warranty documents for all bulk shipments.

Q:Will panels lose power under high temperature?

This N-type solar module has finished 2000 hours PID aging test and strict anti-LID inspection according to international standards. It has a temperature coefficient of negative zero point three zero per cent per degree, so the power generation drop will be greatly reduced when working under high temperature environment.
