Conventional Solar Panel
Solar panels are devices that convert light into electricity. They are called "solar" panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaics which means, basically, "light-electricity.“
They are available in 40watt, 50watt, 60watt, 80watt, 100watt till 340watt.
Flexible Solar Panel
Standard solar panels are rigid, the front protective layer of solar cells is a thick (3-4 mm) tempered ultra-clear glass. This standard solution has been tested for more than 70 years and it is undoubtedly the best to protect cells from weathering and impact, while allowing light to reach them. Flexible panels cannot use glass, obviously, but polymers. Transparent polymeric films have been always thought as a glass replacement, they are lighter and unbreakable.
