The 75w solar panel to be a strong and rigid module

75W Solar Panel75W Solar Panel.

The 75w solar panel to be a high-performing solar module. Newpowa distributes these 75 watt modules.

They call it the NEWPOWA 75 Watt 12V Monocrystalline Solar Panel.  It is a newer smaller construction, but the same output as the older bigger panels.

This is because the manufacturer uses cells with higher efficiency. That is comparing to most other brands.

It is a NewPowa NPA75S-12H, 75W 12V Mono High efficiency solar panel.

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

Compatible mount brackets are: NPB-UZ, NPB-100P. You have to buy it separately.

The manufacturer uses high-performance cells that they encapsulate in EVA (ethylene-vinyl acetate).

EVA (ethyl vinyl acetate) is available in thin sheets. 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 pair of 3 feet MC4 cables attached to the Junction box. It has MC4 connecters male and female attached to the ends. Ready to use.

Also pre-drilled holes for easy mounting.

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

On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 445 watt.

That is 7 x 75 watt = 525 watt.

Now you allow for a loss of 15% and you get 525 X 85/100 = 446.25 watt.

Ignore the 1.25 and you get a fair 445 watt per 7 hour day.

The Corrosion-Resistant Aluminum Frame

Durable anti-corrosive frameDurable anti-corrosive frame.
  • The heavy-duty anodized frame is solid and comes with pre-drilled holes for mounting.

  • With a rugged design, the 75w solar panel 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.


  • The 75W/12V Monocrystalline solar panel is a High-Efficiency solar module.

  • The module has a nominal standard 12V DC output.

  • The pre-drilled holes help for easy mounting and flexibility.

  • Rugged design to withstand high winds (2400Pa), hail and snow load (5400Pa)

  • The pre-attached 3ft wire with MC4 connectors ensures immediate and ease of operation. (Male and female connector.)

  • The wires are good thick high-quality conductors.

  • The 75w solar panel produces a fair amount of power. Even on cloudy days and under shady conditions.

  • NewPowa offers free shipping for all domestics orders (48 states). The will ship your order will within 1-2 days from the date after receiving payment.

Disadvantages of the 75w solar panel

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.

A good option is to mount brackets on the short side if you want to angle the 75w solar panel.

You will have to drill some holes then. Drilling holes is not a major job, but you have to be very careful when drilling.

To Mention

  • The 75w solar panels are well built and can withstand higher winds without problems.

  • The panels look good and are very well made.

  • The modules can withstand wind, rain, and snow, but never step on it.

  • Remember when mounting the panel to leave room between the solar panel and the surface. This is to avoid the buildup of excessive heat.

  • It is important to always use the right size of wire to ensure the largest flow of electric current.

  • This is a good unit that performs according to specifications.


The 75w solar panel comes with a 2-year limited material and workmanship warranty

Also a 10 year 90% output warranty and a 25 year 80% output warranty.

In a conclusion

The 75w solar panel delivers well during periods of good sunshine. It also produces satisfactory under low light conditions.
