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 panels.

They name them NEWPOWA 75 Watts 12V Mono Panels. The construction is newer and smaller, with 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.

It does not come with a charge controller neither a mounting hardware.

The compatible mounting 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 watts.

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 holes that are pre-drilled. This is for easy mounting.

  • The 75w solar panel withstands high winds (2400Pa), and heavy hail and snow loads (5400Pa). This is because of the good and rugged design, 

  • This is a 75w solar panel with high-transparent, as well as low iron tempered glass.

  • It has  durable TPT back sheet helps for dissipation of heat. This is for increased panel performance and a longer panel life.


  • The 75W/12V Monocrystalline solar panel comes with a high conversion efficiency.

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

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

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

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

  • The wires are well made and thick. They are of good-quality conductors.

  • The 75w solar panel has high output. It also produces well when cloudy or shady conditions.

  • There is free shipping for all domestics orders (48 states). They will ship your order will within the first two days from the date after payment.

Disadvantages of the 75w solar panel

Some people complain that they do not get max power from the panels. Remember though that ideal condition is mid-summer and time of day when the sun shines perpendicular to the panel.

Real output varies depending on the place you stay, season and time of day.

A good option is to mount brackets on the short side if for angling the 75w solar panel.

You must drill some holes then. Drilling holes is easy, but work careful when drilling.

Mentioning some facts

  • The 75w solar panels are high quality.

  • The panels are looking good and also 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 surface and panel. That's for preventing 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 module has a  two year limited workmanship and material warranty.

Also a ten year 90% output as well as twenty five 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.
