You can use this 400w solar panel  to generate cheap electricity

400W solar panel400W solar panel.

Use the 400w solar panel for various applications. It is good for AC and DC applications as well as battery charging.

This handy improved 400w solar modules are from Trina Solar.

They call it the Trina Tallmax M TSM-400 DE15M(II) 400w solar panel.

It has a  a 25-years limited output guarantee.

With this Tallmax M module, the manufacturer uses half-cut cells and multi-busbar technologies.

They split a cell in half when using this half cell technology. This is for improved performance and durability. It Optimizes power output under inter-row shading conditions and reduces interconnection losses.

With PID-free(potential induced degradation) components, the 400w solar panel delivers high-power output. This  high output can last for 25 years or more.

PID of PV panels will reduce output power over time. 

400W solar panel performance

With 7 hours sun in mid summer, it is easy to generate about 2800 watt.

This is 7 x 400 watt = 2800 wattage.

Allow for 15% loss and you have 2800 X 85/100 = 2380Watt.

You can use the 400w solar panel for residential or commercial purposes.

Use the 400W solar panel from Trina Solar on or off the grid.

Measurement is 2024 × 1004 × 35 mm.

The 400w solar panel comes with  one meter cables tied to the junction box. Also MC4 connectors.

An IP68 rated junction box.
