What is Solar Energy?
Updated: Jul 23, 2018
Solar energy can be (1). Light and heat provided by the sun or (ii), a slightly longer answer: after running the gauntlet from an average of 93 million miles away, through the various layers of atmosphere and atmospheric conditions (clouds, pollutants, dust and the like), about half of the solar energy is absorbed by water and land, with the other half reflected and re-radiated back into space.
The half that makes it is absorbed by oceans, land masses and plants; in the ocean, the energy drives heat and wind-driven currents (like the Gulf Stream); on land, the energy is absorbed and creates heat, and the little bit that’s left is absorbed by plants and converted to chemical energy through a process we all know as photosynthesis.
Solar power is very safe, reliable and effective, requiring no moving parts, it emits no carbon dioxide, fumes or pollution, and the panels will typically produce power for at least 25-30 years. A solar power system uses photovoltaic (PV) technology to harness the sun’s rays, converting sunlight photon energy into electrical current.
Solar power panels produce energy from daylight, not direct sunlight, so they still produce electricity on cloudy or overcast days. Solar power can be used directly in your home to power lights and appliances – or exported to the electricity grid. At night when your panels can’t produce electricity, you draw your electricity from the electricity network in the normal way. A solar power system contains two major elements: solar panels, which are usually mounted on a rooftop, and an inverter.
The solar panels contain two layers of silicon, one with a positive charge and one with a negative charge. When the sun’s rays land on a panel, electrons move from one layer to another, creating an electrical current. The inverter takes the current and converts in into usable power (120V&240V AC).Solar energy is long-term money saving investments, with up to TEN (10) YEARS warranty your system, customers are assured that Construction Energy will be reliable and we service what we sell.
