Solar is a great alternative.

The 120W solar panel is a High-Efficiency Mono Module

The 120W solar panel is a high-performance module. NewPowa distributes these rigid and strong solar modules.

They call it the NEWPOWA 120W 24V Monocrystalline Solar Panel. It is a High-Efficiency Mono Module.

It comes with pre-installed diodes in the junction box.

Also a pair of 3 feet MC4 cables attached to the solar module.

As well as  male/female connectors.

The package does not include a charge controller or mounting hardware.

The manufacturers insert these thin sheets between the solar cells. Also between the module and the top surface. They also use it between the module and the back surface.

They use heavy-duty anodized aluminum frames for solar panels. That provides for high-quality panel rigidity.

One can use these solar panels for many years. You will experience no faults, defects, or operating failures.

It comes with a superb warranty for up to 25 years.

The output of the 120w solar panel

On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 700 watts.

That is 7 x 120 watt = 840 watt.

Now you allow for a loss of 15% and you get 840 X 85/100 = 714 Watt

Ignore the 14 and you get a fair 700 watt.

Junction Box

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).

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.

Advantages

• Pre-installed diodes in the junction box ensure safe operation.


• The solar panel has a solid frame and it comes with pre-drilled holes.


• The connectors on the end fit perfectly in standard MC4 connectors and the wires are good thick high-quality conductors...


• The 120W solar panel has the ability to produce a fair amount of power. Even on cloudy days and under shady conditions.


• The solar module withstands strong winds and heavy snow loads.

Disadvantages

Some people were complaining that they do not get max output when using the panels. We must remember though that ideal condition is mid-summer. Also when the sun shines perpendicular to the panel.

The real output varies depending on where you stay and what season it is.

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

If you want to angle it you have to mount brackets on the short side. You will have to drill some holes then. Drilling holes is not a major job, take care when drilling.

Some facts to mention about the 120w solar panel

It is a fact that these panels are well built and can withstand higher winds without any problems.

The panels also look good and are very well made.

The 120w solar panel is only a bit larger than a 100-watt panel. It operates even with partial shading.

The module works well even when you mount it flat on a vehicle’s roof...

We should remember it can support wind and rain, but do not step on it.

When you mount the solar panel remember to leave enough room between the solar panel and the roof.

It is important to see that wire you use is always the right size for the greatest amps flowing in the system. Use circuit breakers or fuses to protect the system when exceeding those limits.

Warranty

There are 2-year limited materials and workmanship warranty.

It includes a 10 year/90% power output warranty.

It guarantees an 80% efficiency rate 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 usable power. The design is safe and stable and shipping is prompt when you order.
