How solar panel system works
The usage ofgoes back to 1839 when Alexandre Edmond Becquerel discovered the photovoltaic phenomenon, describing how energy may be created from sunshine.
The cost of solar energy has plummeted in recent years as the demand for ￼green energy sources rises and technological efficiency improves.
Today,s are a practical means of decreasing your power costs (although they may be pricey at first) as well as enabling you to do your part in the effort to live self-sustainable, or at least minimize the carbon imprint in your house. It’s a simple approach to help rescue the earth, so you’re doing right by your children and your children’s children too.
Let’s take a straightforward, step-by-step look at how the solar panel system works.
Step-1: Sunlight activates the panels
Each individual panel is built of a layer of silicon cells, a metal frame, a glass case wrapped by a unique coating, and wiring. For optimal impact, the panels are arranged together into “arrays” (an ordered sequence) and installed on roofs or in vast outdoor locations. The solar cells, which are often referred to as photovoltaic cells, absorb sunlight during daytime hours.
Step-2: The cells create an electrical current
Within each solar cell is a tiny semiconductor wafer manufactured from two layers of silicon. One layer is positively charged, and the other is negatively charged, generating an electric field. When light energy from the sun impacts a photovoltaic solar cell, it energizes the cell and causes electrons to ‘come loose’ from atoms inside the semiconductor wafer.
Step-3: The electrical energy is transformed
You now have solar panels operating effectively to change sunshine into energy, but the electricity created is termed direct current (or DC) electricity, which is not the sort of electricity that powers most houses, which is alternating current (or AC) electricity. Fortunately, DC power can readily be transformed into AC electricity using a machine called an inverter. In current solar systems, these inverters may be set as one inverter for the whole system or as separate microinverters installed behind the panels.
Step-4: The transformed energy runs your house
Once the solar energy has been converted from DC to AC electricity, it goes via your electrical panel and is dispersed throughout the house to power your appliances. It operates precisely the same manner as the electrical power produced via the grid by your electric utility provider, so nothing inside the house has to change.
Step-5: A net meter monitors use
On cloudy days and overnight, your solar shingles or panels may not be able to catch enough sunlight to utilize for electricity; conversely, in the middle of the day when nobody is home, they may gather excess energy—more than you need to power your house. That’s why a meter is used to monitor the power flowing in both directions—to and from your house. Your utility provider will typically pay credits for any extra electricity you send back to the grid. This is known as net metering.
Solar panels absorb solar energy from the sun and convert it into DC electricity. DC electricity is converted to AC electricity by inverter technology, which is used by most home appliances. Any extra electricity produced by solar panels is fed back to the electric grid via an inverter.
