Myths and Facts About Solar Energy

As the global evolution continues to take shape as regards renewable energy, the doubters yet remain.
Africa remains a land of huge potentials when renewable energy comes to fore. As in the case of solar energy, with abundance of sun to tap energy from, the possibilities remain endless.

3.827 X 10^26J is the amount of energy the sun emits in one second. However, this value supersedes the total amount of energy from fossil fuels currently present on earth. A value that stands at 3.9 X 10^22J.

Solar Energy remains a source that may never be exhausted in terms of energy production.

Below are some myths and facts about solar energy.

MYTH #1: Solar powered devices do not work at night.

FACT: Many solar powered devices harness energy from the sun during the day to be used later at night.

MYTH #2: You cannot convert solar energy on a cloudy day.

FACT: Although not as effective as on a sunny day, producing 10-25% of its regular capacity, solar energy can still be converted on a cloudy day. Germany, which gets as much sunshine as the state of Alaska, is the world’s top solar panel installer, producing 31% of the world’s renewable energy.

MYTH #3: Solar powered lights are not bright.

FACT: As technology is improving, the quality of light from solar powered lights is also improving, so the concern over the brightness of light is no longer relevant. Many portable solar powered lights have the option to adjust brightness levels.

MYTH #4: Solar power is too expensive and unaffordable.

FACT: The price of solar power has been rapidly decreasing through the years, which is one of the reasons why over 60% of the United States’ solar panels were built in the past 3 years.

MYTH #5: Under extremely hot temperatures, PV cells can produce more electricity.

FACT: PV cells use sunlight and not heat to convert into electricity. So contrary to popular belief, higher temperatures actually lower the efficiency of PV cells.
