How Are Solar Panels And Solar Energy Produced?

Have you ever looked at rooftop solar panels and wondered how they work. Well Solar Agriculture Services in Pakistan those high-tech shimmering glass surfaces are actually just one piece of a complex. Network that harnesses the sun’s renewable energy to provide electricity to the home.

How Do Solar Panels Produce Electricity?

Sunlight Activates The Panels. Each individual panel consists of a layer of silicon cells, a metal frame. A glass envelope surrounded by a special film and wiring. For maximum effect, the panels are grouped into “arrays” (an ordered series) and placed on rooftops or in large outdoor spaces. Solar cells, also called photovoltaic cells, absorb sunlight during the day.

Cells Produce Electric Current

Inside each solar cell is a thin wafer of semiconductors made up of two layers of silicon. One layer is positively charged and the other negatively, thus forming an electric field. When light energy from the sun strikes a photovoltaic solar cell, it energizes it and causes electrons to detach from atoms. In the semiconductor wafer. These free electrons are set in motion by the electric field surrounding the wafer, and this movement creates an electric current.

Electrical Energy Is Converted

You now have solar panels that work efficiently to turn sunlight into electricity. But the electricity produced is called direct current (or DC), which is not the type of electricity that powers most homes. Namely alternating current (or AC). Luckily, direct current can easily be turned into alternating current with a. Gadget called an inverter. In modern solar systems, these inverters can be configured as a single. Inverter for the entire system or as individual microinverters attached behind the panels.

Converted Electricity Powers Your Home

Once the solar energy has been converted from direct current to alternating current. It passes through your electrical panel and is distributed throughout the house to power your appliances. It works exactly the same way as the electrical energy generated by your electricity company’s grid. So nothing has to change in the house. Since you remain connected to your traditional power company, you can automatically draw additional electricity to supplement any solar shortages from the grid.

A Net Meter Measures The Consumption

On cloudy days and at night, your shingles or solar panels may fail to capture enough sunlight to use as a power source; conversely, in the middle of the day, when no one is home, they can collect excess energy, that is, more than you need to run your home. This is why a meter is used to measure the flow of electricity in both directions – to and from your home. Your utility company will often give you credits for any excess power you send back to the grid. This is called net counting. Now that you know the basics of solar energy, you can marvel at how today’s photovoltaic technology can harness the immense power of the sun to run a home. It might not be science-fiction, but it’s certainly human ingenuity at its finest.
