The sun-directly or indirectly-is the primary resource for many kinds of energy found in the world. Solar energy is tidy, plentiful and also renewable.
Although we think of solar energy as a something new, some of our ancestors from the older civilisations found some very ingenious methods to make use of solar energy, without the technology we have today. Among them, the Chinese, Romans and Greeks all developed methods to use the power of the sun to heat for their homes, including using southerly direct exposures to optimise solar heating and utilising the suns light.
Now, thanks to all of the innovative modern technologies, it is actually possible to capture this power from the sun, focus it, store it and also transform it into electricity we can use.
The rays from the sun are converted into electrical power by solar cells. Solar cells are also called solar batteries, PhotoVoltic cells or “PV cells” for short. PV cells were initially developed in the 1950s for use in American space satellites. Today, they are used to power various things ranging from telecommunications to getting electricity out the rural areas. You can also find PV cells on things we utilise daily, such as calculators, flashlights, radios, garden lighting as well as children’s toys.
Mobile PV systems are becoming more readily available for emergency situation and disaster use, such as keeping mobile phones and small home appliances charged when the individual is away from the grid or throughout power outages.
As a consumers you can now harness the power of the sun a lot more easily than ever before. The solar panels you see on various structures and also on houses, offices and other business premises have been on the market for years, but were way over priced for the majority of households to afford them. New systems are being developed continuously, such as the solar PV cells which are built into roof shingles. They are reliable, resilient as well as more cosmetically pleasing.
The power of the sun isn’t only used to generate electricity. It can also be used to warm water, which can then be utilised to warm homes and businesses. Some of the solar powered radiant heat systems are use to run industrial processes which drive turbines to create electrical energy. There a a number of solar thermal technologies that have been used in homes for decades and they can last for greater than 20 years.
All of the solar energy experts believe that the solar power innovations will not only help the country but other counties and the planet as a whole. Solar energy has the potential to help diversify the countries power supply, minimise our dependence on imported fuels, improve air quality, counter greenhouse gas discharges and to stimulate the economy by creating jobs in the production and instalment of solar power systems.
