Understanding the Source: The Fascinating Anatomy of a Solar Panel
Children, ever curious, are quick to ask how things work. As we grow older, some lose the propensity to wonder how things work. For example, simply flicking a switch and illuminating a room requires electricity.
The world once relied on candles and sunlight alone for illumination. Electricity and other sources of power enable more possibilities. Of course, those, kind to the earth, find clever ways to cleanly and safely generate energy. Solar panels capture sunlight, using electrons as an eventual source of energy to power homes, buildings, businesses, etc.
Sunlight becomes electricity via the capture, extraction, and transfer of electrons. Photons, particles of light, pass through sunlight atoms, shaking electrons free. The electrons are attracted to tiny cells in solar panels which then transfer the electrons to metal panels. Lastly, electrons gather in the plates and then transferred to wires to produce electricity.
Each tiny cell is formed like a sandwich. Two ‘slices’ of silicon cells, fit with negative and positive materials, generate an electrical field of energy. Phosphorus and boron work in opposition to cause a reaction. Photons of light knock available electrons free, and the electrons then pushed out of the silicon network and transferred to metal plates. The plates send impulse to wires and then to homes, which eventually serves as electricity.
Other forms, such as solar thermal and concentrated solar power, help home and business owners ‘go green’ and avoid high utility costs. Speak to available vendors about how to harness the power of the sun with photovoltaic cells, or systems that use heated water or air. Depending on area and location of home or building, vendors may propose one or a variety of solutions.
Each situation and need differs. Ideally, if you lived at the equator and installed a network of solar panels, you would take full advantage of the sun’s power. However, most people do not live at the equator nor require to meet the max power rating. Speak to vendors aboutsolarpanels in Perth or your local area, so your expectations are not met with disappointment regarding costs versus savings.
Entrepreneurial minded home and business owners seek ways to save and make money. ‘Net metering’ provides owners opportunity to make money on supplemental energy stored. For example, a Floridian homeowner, fixing a network of panels to his modest-sized home, may produce more than enough energy to address the needs of the estate. The storage of energy transfers to supplemental income for those in such situations.
Like those who regard exercise as a lifestyle choice rather than immediate fad, those who choose to invest in solar energy make additional choices to benefit. Using LED bulbs, lighting candles at night, and choosing window air units (rather than central systems) saves more money and supports green living.
Those making the commitment to solar energy save money and explore future options that actually produce added incomes. Speak to available vendors about making an investment in your home or business.
