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
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.

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