The 380w solar panel helps you to become independent

380W JA Solar Mono Half Cell Panel380W JA Solar Mono Half Cell Panel.

This 380w solar panel is good for a variety of applications. It is handy to use as a source of power to charge batteries or to use for AC or DC appliances.

JA Solar manufactures these handy and improved 380w solar modules.

We call it the 380W JA Solar Mono Half Cell Panel.

JA Solar assembles these solar modules with multi-busbar perc cells. With perc cell technology they integrate a passivation layer on the back of the surface. This layer of material boosts cell efficiency.

They also make use of half cell technology. With half cell technology they cut a solar cell in half. This is to improve performance and durability.

By making use of PID-free components, the manufacturer ensures a high-power output. A high output that will last for many years. PID of PV modules reduces output power over time. (PID is the so-called potential induced degradation.)

Performance of the 380w solar panel

On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 2260 watts.

That is 7 x 380 watt = 2660 watt.

Now you allow for a loss of 15% and you get 2660 X 85/100 = 2261 Watt.

Drop the one and you get a fair 2260 Watt.

The module is for residential purposes as well as commercial use.

You can use the 380W JA Solar Mono Half Cell Panel from LG for off-grid or on the grid applications.

The size of the panel is 1776 × 1052 × 35 mm.

The 380w solar panel has cables attached to it via the junction box.

The Junction Box is IP68 rated and comes with 3 bypass diodes. The length of the cables is 1 meter, and it comes with MC4 connectors.

Junction Box

The 380w solar panel comes with an IP68 rated waterproof junction box. It comes with 1000mm long tails that connect to the junction box and MC4 connectors and the open ends.

The box is durable and can last for many years. It provides complete protection against harsh weather conditions.

The junction box contains three bypass diodes. In the case of partial shading, the diodes activate. It bypasses any current generated by non-shaded cells. This is to limit module heating and performance losses.

The diodes ensure a constant output.


The module manufacturing processes of JA solar are of a high standard. They succeed to keep on improving efficiency and reliability.

The 380w solar panel comes with a high price to performance ratio.

The junction boxes provide for easy serial connection. This is when using more than one 380w solar panel.

With the half cell technology, you get;

Higher power output.

Improved temperature-dependent performance.

Reduced shading effect.

Low risk of a hot spot and better tolerance for mechanical loading.


The 380w solar panel comes with a 10-year product warranty. This is on materials and workmanship.

It also comes with a 25-year linear performance warranty.

In a conclusion

The JA 380w solar panel is of high quality. The manufacturer sees to it that the manufacturing and testing are thorough.

It comes with an efficiency of 20.6% and high power output per square meter.
