15 Facts About Solar Energy

15 Facts About Solar Energy

The consumption of non-renewable sources like oil, gas and coal is increasing at an alarming rate. The time has finally come to look after some other renewable sources of energy, i.e., solar, wind and geothermal energy. Although many countries have started utilizing solar energy extensively, they still have to go a long way to exploit this renewable energy to fulfill their daily demand for energy.

“ Consumer interest in solar is growing rapidly – and it shows. ”

Fact 1: Solar energy is a completely free source of energy, and it is found in abundance. Though the sun is 90 million miles from the earth, it takes less than 10 minutes for light to travel from that much distance.

Fact 2: Solar energy which comprises of radiant heat and light from the sun can be harnessed with some modern technology like photovoltaic cells, solar heating, artificial photosynthesis, solar architecture and solar thermal electricity.

Fact 3: Solar powered hot water systems utilize solar energy to heat water. In certain areas, 60 to 70% of the water used domestically for temperatures as high as 60 degrees Celsius can be made available by solar heating.

Fact 4: Solar energy can also be used for making potable, brackish or saline water. Without using electricity or chemicals, wastewater can be treated. Creating salt from seawater is also one of the oldest uses of solar energy.

Fact 5: Thermal storage systems can store solar energy in the form of heat by using common materials with high specific heat such as stone, earth and water. Solar energy can also be stored in molten salts.

Fact 6: Solar energy is being recognized as the future of alternative energy sources as it is non-polluting and helps combat the Greenhouse effect on the global climate created by the use of fossils fuels.

Fact 7: Solar Energy is measured in kilowatt-hour. 1 kilowatt = 1000 watts.

Fact 8: Solar energy produces no pollution, has no environmental effects and is ecologically acceptable.

Fact 9: The largest solar power plant in the world is located in the Mojave Desert in California, covering 1000 acres.

Fact 10: Solar energy is the preferred mode of creating power where the need is temporary. For e.g., temporary fairs, mining sites, Olympics.

Fact 11: Solar panels are virtually maintenance-free since the batteries require no water or other regular service and will last for years. Once solar panels are installed, there are no recurring costs.

Fact 12: Solar power can significantly reduce electricity bills. Moreover, there are many tax incentives and rebate programs designed to spur the use of solar and save homeowner’s money at the same time.

Fact 13: A home solar panel system consists of several solar panels, an inverter, a battery, a charge regulator, wiring, and 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.

Fact 14: By relying on battery backup, solar energy can even provide electricity 24×7, even on cloudy days and at night

Fact 15: Solar power is free of noise pollution. It has no moving parts and does not require any additional fuel, other than sunlight, to produce power.
