Providing Solar Solutions for a Sustainable Future
Fact 1: Solar energy is a completely free energy source, and it is found in abundance. In less than 15 seconds, the sun provides enough energy for all human consumption for the entire day. 1 hour of sun equals 1 year of global energy.
Fact 2: Solar energy is being recognized as the future of alternative energy sources. It is non-polluting and helps combat the Greenhouse effect on global climate created by fossils fuels. Solar energy can replace fossil fuels and allow us to make various storable and transportable fuels, such as hydrogen.
Fact 3: Producing solar energy is straightforward. Using the photovoltaic effect of 2 layers of silicon, solar cells can convert the sunlight into electricity. This process was developed by Bell Laboratories in 1954. The first solar cells were available for purchase in 1956, but at $300 per Watt, only a few could afford them.
Fact 4: Between 1977 and 2015, the cost of solar panels has dropped by 25,333 %.
Fact 5: Solar panels are virtually maintenance-free and will last for at least 25-30 years. Once solar panels are installed, maintenance is minimal, and there are no recurring costs.
Fact 6: In order to work, solar panels don’t need direct sunlight to produce electricity. However, direct sunlight has the most energy.
Fact 7: 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. Nowadays, concentrated power plants use the same technique to produce steam and make electricity.
Fact 8: Apart from producing electricity, the heat of the sun can also be used by solar-powered hot water systems. In certain areas, 60 to 70% of the water used domestically can be made by solar heating. By that, it can reduce your energy bill tremendously.
