If you’re wondering whether the solar panel is producing AC or DC power, you’re not alone Lets understand this. Many people are curious about how solar energy actually works, especially when it comes to powering homes and appliances. In simple terms, the solar panels are generating DC voltage, but most of the home appliances is run on AC voltage. That’s why a device called a inverter is needed to converting the DC to AC voltage. In this beginner friendly guide, I’m explain everything you need to know about solar power, AC and DC electricity, and how they work together in a solar system.
What Type of Power Do Solar Panels Produce?
The solar panels are producing DC voltage. When the sunlight is hits on the surface of the solar panels it will activating the photovoltaic cells inside of the solar panels. which will converting the light energy to DC voltage. The output of the solar panel will be pure DC voltage same as we can get from the battery.
In our house most of the appliances and the electrical grid operate on AC power. To run this electric device we need an AC power so, the DC voltage is converter into AC using an inverter.
Why Do Homes Use AC Instead of DC?
In home the AC voltage is using insted of DC, because of the AC voltage is more efficient for transmitting over a long distance. in high voltage of around 100Kv or 320kv it can transfer from power station to other sub stations with very less power loss.But the DC voltage transfer through a conductor or wire for long distance is difficult because of the less efficiency.
Another reason is compatibility. Since the grid and most home home appliances are designed to works on AC current. it makes sense to build homes with AC wiring. That’s why even though solar panels produce DC power, it must be converted into AC using an inverter before it powers your lights, fans, and appliances.
How Does a Solar Inverter Work?
The solar inverters are electronic device used to converting the solar energy to AC voltage. The solar panels producing DC voltage such as direct current, this will be feed into the power supply of the inverter to converting DC to AC voltage.
The converter AC voltage is around 110V to 240V of AC, this can be suitable for everyday working devices like lights, TVs, and refrigerators. Without a solar inverter, the energy from solar panels wouldn’t be compatible with your home or the electrical grid.
There are different types of solar inverters are available in the market. Which are string inverters, microinverters, and hybrid inverters. Some systems use one central inverter for all panels which is called as string inverter. While the others use one small inverter per panel it is called as microinverter.
Micro inverter are more efficient because it convert direct dc voltage to AC and attached at the bottom of solar panel. The hybrid inverters comes with battery storage and it will allow you to save excess energy for later use. Many modern inverters come with monitoring tools, so you can track how much energy your system is producing and using.
