Solar is a great alternative.
The 70W solar panel is a high-performance module. NewPowa distributes these rigid and strong solar modules.
They call it the NEWPOWA 70W 12V Monocrystalline Solar Panel. It is a High-Efficiency Mono Module.
The package does not include a charge controller or mounting hardware.
We can buy compatible mount brackets separately. (NPB-UZ, NPB-0103, NPB-100P).
This is a high-efficiency mono panel and the color is black.
It comes with a pair of 3 feet MC4 cables attached to the junction box. Also male/female connectors.
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 will keep on generating free electricity for many years to come.
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 415 watts.
That is 7 x 70 watt = 490 watt.
Now you allow for a loss of 15% and you get 490 X 85/100 = 416.5Watt
Ignore 1.5 and you get a fair 415 watt.

Fridge for camping;
Charges a12 volt security camera 24/7;
Off Grid System;
Many other small applications.
If you want to angle the panel you have to mount brackets on the top side. You will have to drill some holes yourself then.
Drilling holes is not a major job, but you must be careful when drilling.
The 70w solar panel comes with a 2-year limited material and workmanship warranty.
It also has a 10 year 90% output warranty as well as a 25 year 80% output warranty.
The 70w solar produces a lot of power for its size, and it comes @ a good price.
