WHAT ARE THE REAL SOLAR ENERGY FACTS... | | |
Fact No1 solar energy is always there! Can you imagine world without sun! Impossible! | | |
Fact No2 solar energy is free to use! Today’s technology gives us a power to use solar energy! | | |
Fact No3 solar energy is clean! Using solar energy we can save our children future! | | |
Fact No4 every single solar piece you buy and use makes you good guy! | | |
Fact No5 we can use solar energy on active and passive way! | | |
Fact No6 the human use of solar energy is not new! There is a short solar research history… | | |
Fact No7 there are numerous government inventions about using solar energy and other renewable energy sources… | | |
Fact No8 there is clearly a limit to fossil fuel. [Fossil fuel] resources and supplies are likely to peak around 2030 before declining slowly. | | |
Fact No9 we have an obligation to act responsibly, and to protect our planet for future generations! | | |
Fact No10 we must start transition from old to renewable energy right now! | | |

There are many interesting about solar energy facts that describe sun nature. Knowing more about it will help you in making your choices about how to use it. | | |
Solar energy is a term for describing a range of methods for obtaining energy from the sun. | | |
Sun is 109 times bigger than the Earth. The sun’s radius being 696,000km and the Earth’s radius 6, 376km. | | |
The sun’s average surface temperature is 5700 C . | | |
The sun is about 150 million km from the Earth and is aged about 4.5 billion years. | | |
Solar radiation reaches a unit of space near the Earth’s orbit at a rate of 1,366 W/m² | | |
In North America for example the average power of the solar radiation is roughly between 125 and 375 W/m², that is between 3 and 9 kWh per m² per day. | | |
Solar panels deliver only 19 to 56 W/m² or 0.45-1.35 kWh/m²/day of that average power. But that does not make solar energy inefficient! | | |
The average solar energy falling on Australia is equivalent to about 15.000 (fifteen thousand!) times the nation’s present total energy use. At 15% conversion rate that is still more than 2000 times the present need, providing we could capture it all. | | |
The energy output of a 1 KW solar energy unit is equivalent to the burning of 175 pounds of coal and 300 pounds of carbon dioxide being released into the atmosphere. | | |
Bavaria Solarpark covers 25 hectares (62 acres) with 57,600 photovoltaic panels. | | |
Mojave Desert in North America that houses the world's largest solar power plant. It covers 1000 acres (4 km²) of solar reflectors. | | |
Israel is building a 100Mw solar power plant. It will supply more than 200,000 Israelis with electricity. There are further plans for an even more huge 500 Mw solar power plant, making Israel a solar energy leader - about solar energy | | |
