50 watt solar panel comes with high-performance cells for increased efficiency. NewPowa distributes these rigid and strong solar modules.
They call it the NEWPOWA 50 Watt 12V Monocrystalline Solar Panel. It is a High-Efficiency Mono Module.
The panel does not come with mounting brackets. You have to buy compatible mounting brackets extra. (NPB-UZ, NPB-0113, NPB-100P.)
You do need a charge controller to control the charge and discharge. Also if you want to power an AC load, you need an inverter. This is to change the DC power into AC power which is 110 or 220 volts.

It comes with a junction box and a pair of 3 feet solar cables with Mc4 connectors.
They pre-attach the cable to the junction box.
This is a high-efficiency solar panel and the color is black.
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 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 Watt.
Now you can round it and you get a fair 300 watt.
The 50-watt solar panel is best for low-amp systems. It is good for bringing power to smaller electronics away from the grid.

Off Grid Systems;
Small electronics while away from the grid;
Charging both vehicle and deep cycle batteries;
Solar pool heater;
Works great for 12v pump;
Many other small applications.
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.
Other people feel it would be better to include mounting brackets.
NewPowa gives a 2-year limited material and workmanship warranty.
It also has a 10 year 90% output warranty and a 25 year 80% output warranty.
The pricing is a great deal. Buying the 50-watt solar panel will ensure happy hours to spend.
This is while your smaller electronics operate with free electricity.
