A 120W solar panel: This is to be a High-Efficiency Mono Module

120W Solar Panel120W Solar Panel.

This 120W solar panel is a high performer.  Distribution of these strong rigid solar modules is from Newpowa.

This is the NEWPOWA 120W 24V Monocrystalline Solar module. 

It comes with holes already drilled, the junction box with diodes installed, also 3ft MC4 cables.

Male/Female ConnectorsMale/Female Connectors.

As well as  male/female connectoions.

It comes without a charger or z-brackets for mounting.

They use high-performance cells encapsulated in EVA that come in thin sheets.

With the anodized aluminum frames you get strong rigid panels.

These panels can be used for multiple years without giving any problems.

This 120w solar panel has a 25 year warranty.

The 120w solar module output

In summer during a 7 hour day you will get an output of 700 watt. This is if you allow for a loss of 15%.

Junction Box

Junction Box with CablesJunction Box with Cables.

Pre-installed bypass diodes in the junction box ensure safe operation. It reduces power drops caused by shading

It comes with pre-attached 3ft wire with MC4 connectors (M/F)

The junction box is IP65 rated. This provides complete protection against environmental particles and low-pressure water jets.

Durable anti-corrosive frame

The heavy-duty anodized frame comes with pre-drilled holes for mounting.

With a rugged design, it can withstand high winds (2400Pa), hail and snow loads (5400Pa).

Anti-corrosive frameAnti-corrosive frame.

They manufacture the module with high-transparent, low iron tempered glass.

A durable TPT back sheet helps to dissipate heat. This is to ensure better panel performance and lifespan.


  • Already installed diodes bring safe working.

  • The module has a strong frame with holes drilled by the manufacturer.

  • The connections is done with MC4 connectors and the leads are high quality.

  • The 120W solar panel operates well, also under shady conditions.

  • The solar module can withstand high speed winds and loads of snow and hail.


There are people that want holes in the short mounting rails for more mounting options. It only has holes on the longer side.


There are 2-year limited materials and workmanship warranty.

Also a 10 year with 90% power out warranty, as well as 25 year 80% efficiency for 25 years.

To conclude

The 120w solar panel has a very high all around watt/dollar value.

Newpowa supplies a great product at a competitive price.

The module produces more than satisfactory.

Shipping is prompt when you order this safe and stable designed solar panel.
