How does solar panel works
Solar panels are composed of a large number of solar cells. Solar cells, like semiconductors, are made of silicon. They are composed of a positive and a negative layer, which together generates an electric field, much like a battery does.
Solar photovoltaic (PV) panels produce direct current (DC) electricity. When direct current electricity is used, electrons flow in a single direction around a circuit. In this example, a battery is used to power a light bulb. The electrons travel from the negative side of the battery to the positive side, passing through the lamp.
Essentially, yoursystem utilizes photons to separate electrons from atoms. Photons are subatomic particles of light. Solar electricity is generated by the process of electrons being separated from their atoms.
Now, let’s take a closer look at how solar panels operate. When it comes to solar panels, the process is truly straightforward and can be summarised in five simple steps:
1- Solar panels capture the sun’s energy
Each photovoltaic (PV) cell is contained within a solar panel. PV cells convert light, or photons, to solar energy. When sunlight strikes a photovoltaic (PV) cell, direct current (DC) electricity is generated.
This is all well and good — but DC electricity cannot sustainably power your home. This is where additional solar energy equipment comes into play. Let us now discuss solar inverters!
2- Solar energy is converted to usable electricity by inverters
Certain solar panel configurations use a single inverter (commonly referred to as a string inverter) to power the entire system. A microinverter is connected behind each solar panel in some. The most critical aspect of inverters is that they convert direct current (DC) electricity generated by solar panels to alternating current (AC) electricity. This electricity is responsible for powering your home. We’ll begin.
3- Solar electricity is used in the home
Solar energy flows through your net meter, warms your home, and powers your appliances. It operates in the same way as conventional electricity does now—nothing needs to be changed. If your solar panels do not generate enough energy to meet your entire electricity consumption, have no fear. You remain connected to traditional power companies via the grid, which enables you to automatically draw additional energy from your utility as needed.
4- Leftover solar electricity goes to the grid
While it may seem counterintuitive to be connected to the traditional power grid when you have a solar energy system, being connected to the grid has a number of benefits. It enables you to consume as much electricity as necessary before sending any excess solar energy to your utility company. Solar panels generate electricity when the sun is shining, but we also use electricity at night when the sun is not shining.
5- The net meter is used to determine the amount of solar energy generated
This final section will require you to understand what a net metering agreement is. Net metering occurs when your local utility company agrees to compensate you for any excess solar energy you generate and send back to the grid. In some cases, these energy credits can roll over, allowing you to accumulate them over time, and some utilities will even pay you for your energy credits.
The net meter is a device that is installed in the home to monitor the flow of electricity to and from the power grid.
In the last ten years, the price of solar technology has dropped more than 60%, making it more affordable for average households and businesses. Walk around any neighborhood in the U.S. and you’re bound to see more solar panels being put to use year after year.
