Solar Energy Facts

Solar energy refers to energy from the sun. The sun has produced energy for billions of years, and it is the most important source of energy for all life forms. It is a completely renewable source of energy unlike non-renewable sources such as fossil fuels.   The sun provides a consistent and steady source of solar irradiance. Solar Power technologies use the sun’s energy to light homes, produce hot water, heat homes and to produce electricity.

The primary benefit of solar energy is that it provides a tremendous resource for generating clean and sustainable electricity without toxic pollution or global warming emissions. It is a 100% renewable source of energy that requires low maintenance and is very easy to install. The only limitation that solar energy possesses is that it cannot be created during the night, and the amount of sunlight converted to electricity depends on location, time of day, time of year, and weather conditions.

Below are 20 Facts about Solar Energy

Fact 1: Solar energy is a completely free source of energy and it is found in abundance. Though the distance between the sun and the earth varies between 91.4 million and 94.5 million miles every year, it  takes less than 10 minutes for light to travel to the Earth.  In just one hour, enough sun falls on the face of the Earth to power the whole of humanity for one year.

Fact 2: 
Solar powered hot water systems utilize solar energy to heat water. In certain areas, 60 to 70% of water used domestically for temperatures as high as 60 degrees Celsius can be made available by utilizing solar heating.

Fact 3: 
Solar power is the most exciting use of solar energy. It is how solar energy is converted into electricity by using either photovoltaic (direct method) or concentrated solar power (Indirect).  With concentrated solar power, large beams of sunlight are focused into a small beam using mirrors or lenses. Photoelectric effect is used by Photovoltaic cells to convert solar energy
directly into electricity.

Fact 4: 
Solar energy is recognized as the future of alternative energy sources as it is non polluting and helps combat the Greenhouse effect on the global climate, which was created by the use of fossils fuels.

Fact 5: 
The most common domestic use of solar energy is from solar panels which absorb solar heat energy to use for cooking and hot water.

Fact 6: 
Solar energy produces no pollution, has no environmental effects and is ecologically accepted.

Fact 7: 
Solar energy is now one of the most widely used renewable sources of energy. One can use affordable renewable energy technologies to convert solar energy into electricity.

Fact 8: 
Solar energy is an exceptionally reliable and dependable source of energy.

Fact 9: 
With new advancements in scientific research, solar energy will be even more affordable in the future, with decreasing costs and increasing efficiency. Costs have dramatically fallen in recent years.

Fact 10: 
Solar energy will undoubtedly continue to be the Philippines major source of renewable energy due to its massive potential and long-term advantages.  The current cost of generating Solar Energy over 25 years (Levelized Cost of Energy, or LOCE) is around a fifth of current utility power rates.  Utility rates will rise, whereas solar power is free after you recover your initial investment

Fact 11: 
The earth receives about 1,366 watts of direct solar radiation per square meter. That is an incredible amount of power, but we use very little of this available energy.

Fact 12: 
Solar panels are virtually maintenance free and will last for years. Once, solar panels are installed, there are few recurring costs.  Some of our panels are Guaranteed for 30 years, and the minimum is 25 year Guarantees

Fact 13: 
Solar power can and will significantly reduce your electricity bills. Moreover, there are many tax incentives and rebate programs designed to promote the use of solar, and save home owners money at the same time.

Fact 14: 
Solar power is noise pollution free. It has no moving parts, and does not require any additional fuel, other than sunlight, to produce power.

Fact 15: 
A home solar PV system often consists of several solar panels, an inverter, a battery, a charge regulator, wiring, and other support materials. Sunlight is absorbed by the solar panels and is converted to electricity by the installed system. The battery stores electricity that can be used at a later time, like cloudy days or during the evening.  Nowadays, one can purchase a more reliable “grid tied” solar PV system, which is far cheaper and longer lasting that traditional battery systems. They are recognized in the Philippines and are actually actively promoted by Laws.

Fact 16:
 If relying on battery backup, solar energy can even provide electricity 24×7, even on cloudy days and at night.

Fact 17:
 Solar energy has been used for over 2700 years. In 700 BC, glass lenses were used to make fire by magnifying the sun’s rays.

Fact 18:
 The sun was also the main source of non-renewable fossil fuels (coal, gas and petroleum) which began life as plants and animals millions of years ago. How ironic

Fact 19:
 Clouds and pollution prevent the sun’s rays from reaching the earth.

Fact 20:
 Solar energy is used in many applications including Electricity, Evaporation, Biomass, and Heating water for buildings.
