1640x990x40mm High Quality 250W 30V (60cells) Polycrystalline Solar Panel for Grid Tie or Off Grid Solar Power System

 

Introduction

Solar panel is the heart of a solar power system. It transfers the sunshine into electricity to provide the power to the whole system. With the increasing popular of the green power, more and more solar power are application in our daily life, such as solar street light, solar charger, solar roof power system, etc. If you also want to join the team of using solar power, our solar panel is your right choice.

 

250W 30V solar panel is composed of 60 pieces 156x156mm polycrystalline solar cells in series. This type of module is certified according to CE, FCC and ROHS standard. It has characters of high efficiency. Long lifecycle, hail storm proof, and easy installation. 250W solar panel is the most popular for installation solar power system because of the suitable size and enough power.

 

Feature & Datasheet

Manufacture Process

1. Solar Panel Production Process

2. Production Equipment

3. Workshop

4. Solar Panel Inspection

Inspection Steps:

QC 1: Soar Cell Inspection:

All solar cells adopted in our module production will be 100% inspected twice. The first 100% inspection in made in cell manufacturing workshop. The second 100% inspection is made in incoming material inspection in module manufacturing workshop. Purpose of the twice 100% inspection is to mark sure every piece of solar cells is good quality and minimize the NG rate in module production.

 

QC 2: EL Test:

Each piece of modules in manufacturing workshop shall pass twice EL test. The first EL test is made before laminating. The second EL test is made after laminating. Purposes of the twice EL test is to detected defective cells in a single module and avoid leakage to our customers.

 

QC 3: Flash Test:

Each piece of modules will be tested in a closed flash test facility with simulated condition which is periodically calibrated by the authorized thirty parties. Each piece of modules will be classified to different grade according to the flash test result.

 

QC 4: Final Inspection:

Each piece of modules will be inspected before packing to ensure high quality.

The EL test, flash test and final inspection result of each module are recorded. The modules are traceable by the label stick on each module.

 

Ongoing Validation

Validating that raw material and finished products meet expected long-term performance through accelerated environmental testing.

Tight Package

Solar panel is very precious products, we pack every of them is very carefully and professionally to keep it safety to our customers' hands. Few customers complain the packaging problems to us. This is the proof of our professional and customer first sevice attitude.

 

Application

Solar panels have already been widely application for our life. It transfers sunshine to electricity which is totally green power. It is clean and economical in the long run. 

 

1. Residential, commercial or industrial roof tops solar power system 

2. Solar water pump system for irrigation

3. Various application
