50 watt solar panel comes with high-performance cells for increased efficiency. Distribution of the rigid and strong solar panel is from NewPowa.
They call it the NEWPOWA 50 Watt 12V Monocrystalline Solar Panel. It is a High-Efficiency Mono Module.
It does not come with mounting brackets, you have to buy it additional. (NPB-UZ, NPB-0113, NPB-100P.)
You do need a charge controller for battery charging. Also an invertor for AC applications.

They include a 3ft solar cable pair and MC4 connectors. These are attached to a junction box.
This panel which is black in color is of high efficiency and well manufactured.
The manufacturer encapsulate these high-performance cells in ethylene-vinyl acetate.(EVA)
EVA (ethyl vinyl acetate) comes in thin sheets. The manufacturers insert them between cell and cell as well as between panel and top of front surface. Also between panel and the back surface.
They provide for a high-quality panel rigidity by using anodized aluminum frames.(Heavy duty.)
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.
On a sunny day with 7 hours of sunlight in mid-summer, you can bargain for the generation of about 350 watts.
That is 7 x 50 watt = 350 watt.
Now you allow for a loss of 15% and you get 350 X 85/100 = 297.5 Watts.
Rounding it and you get a fair 300 watts.
This 50-watt solar module is better for low-ampere systems. Their purpose is to bring power to smaller appliances when not close to the grid.

Off the Grid Systems;
Small electronics while away from the grid;
Charging both vehicle and deep cycle batteries;
Solar pool heater;
Various small appliances.
Some people complained that the panels lack max output. It is important though to remember that ideal condition is mid-summer. Also when the panel is perpendicular to the sun.
Output will always vary. It depends on where you stay, what season it is as well as time of day.
Many people would like it better if the manufacturer includes mounting brackets.
NewPowa gives a two year material and workmanship guarantee.(Limited.)
Also a ten years 90% output warranty and a twenty five year 80 percent output warranty.
Pricing is a great. Buy this 50-watt solar panel and you will have happy hours to spend.
This is while your small appliances operate with cheap electricity.
