Green energy solar technology is powered by the sun to produce electricity and hot water for businesses, residential homes and even industries. Solar power helps to create a green environment that helps the planet. The solar energy that is harnessed helps to minimize our dependence on fossil fuels which are known to create a buildup of carbon dioxide in the earth’s upper atmosphere.
Over the last few decades, the advancements in green energy solar technology has made panel production to be more efficient. This means that solar power is becoming less expensive than it has ever been.
This technology was once used only to power telescopes and vehicles on the moon. It is now used in residential homes, office buildings, commercial structures, warehouses and farms. As solar energy technology continues to advance, it will become more affordable that current energy sources and create new jobs.
Ways To Use Solar Energy
Photovoltaic Systems – Solar panels are used in an array to capture energy from the sun and produce electricity.
Heat Water – This is used by residential and commercial buildings to produce the hot water supply powered by the sun.
Passive Energy – Homes and buildings are built in a way that uses the sun to heat and light without using any type of power source. Windows are positioned in a way to get the most light and heat and the building uses materials to optimize the energy from sun.
Solar Powered Electricity
Solar power captures the sun’s energy to generate electricity. A solar power system typically uses an array of solar panels that consists of photovoltaic cells. The photovoltaic cells then convert the sun’s rays into electricity. These are usually made of silicon and the the PV (photovoltaic) cells operate using computer semi-conductor chips on an array of rectangular panels.
When the sun’s rays hit the cells, electrons are freed of their atoms which provides access into the material. This produces DC (direct current) electricity that is used in that form or it goes through a power inverter which transforms the energy into AC (alternating current) electricity. The energy has to be converted because all homes and commercial buildings use AC electricity to power up appliances, lights, heating and cooling units and other electronics.
Circulation tubes are attached to the system which in turn, heats water to provide hot water to homes and commercial properties.
Solar concentration systems use mirrors that are arranged along parabolic troughs to generate electricity. The sunlight is reflected and then collected to generate steam which spins turbines to create electricity.
Solar technology uses the most powerful renewable resource on our planet – the sun. By collecting these rays of sunlight, it can be converted into heat, steam and electricity. As we move into the future, the cost of solar energy has and will continue to become more affordable allowing a greater number of people access which will significantly reduce our dependence on fossil fuels.
