Understanding Solar Power Basics

Before moving on to really understand our main question, you must first gain an understanding of the two key terms you will be encountering throughout this article: DC and AC.

DC (Direct Current)

Direct Current (DC), as its name suggests, means that in DC, electricity flows in a single, unidirectional stream. It thus creates a steady stream of power. This, in turn, gives DC its unique quality, i.e., its consistent and unvarying voltage.

Because of this, DC is ideal to be used in electronic devices and applications. Batteries are one example of devices that store and supply DC electricity.

AC (Alternating Current)

Alternating Current (AC), on the other hand, does the opposite of DC. AC electricity alternates direction periodically, thus being characterized by a variation in both magnitude and direction over time. This is called a sinusoidal waveform.

While the premise may make it seem like an unreliable form of electricity, it is hardly so. It is precisely because of this quality of AC that AC is used as the standard form of electricity supplied by power grids worldwide.

Because AC alternates direction periodically, it is more efficient for transmitting electricity over long distances. It might be hard to believe, but most of the common household electrical appliances operate on AC.  

 

Why Solar Panels Produce DC Power

Having understood the two key terms, AC and DC, and where they are used, you might be wondering what type of electricity a solar power supply produces. Well, the answer is DC. That’s right; solar panels inherently produce DC electricity.

It is done through the process called the photovoltaic effect, which occurs at the atomic level within the solar cells. It is because of this that solar panels are also called photovoltaic (PV) panels.

Solar panels consist of numerous solar cells made from semiconductor materials, typically silicon. When photons from sunlight hit this semiconductor material, they excite electrons, causing them to move and create a flow of electric current.

These electrons move in a single direction from the negative side of the solar cell to the positive side, thereby creating a direct current - which is DC.

Advantages of DC for Solar Energy Systems

While it may not seem much, the fact that solar power supply inherently produces DC has its own advantages. It is particularly so in solar energy systems because DC power is very efficient for generating and storing energy - which is precisely the purpose of solar energy systems.

DC’s compatibility with batteries used in a solar generator kit or a portable power station is another added benefit. After all, solar energy is stored in these batteries. 

 

The Role of Inverters in Solar Power Systems

Now the question arises: if solar power supply produces DC, but our household appliances run on AC, how can solar power run our household appliances? The answer lies in another device called an inverter. An inverter converts DC to AC.

There are three types of inverters - namely, string inverters, microinverters, and power optimizers. There is a general method of converting DC to AC, though it happens in different ways in different types of inverters.

Upon receiving the DC power, the inverter uses electronic components to create an oscillating current that mimics the sinusoidal waveform (the AC waveform). After this, the inverter synchronizes the AC output with the grid frequency to ensure compatibility with other home electrical systems. The AC power is then delivered to wherever it is needed.

Now, let’s learn how this happens in the three types of inverters, shall we?

1. String Inverters

As its name suggests, a string inverter converts DC electricity from a series (or string) of solar panels into AC electricity. String inverter is the most common type of inverter used in a residential setting.

After all, they are both budget-friendly and easy to install. What more could you need? However, there is one downside to it. If one solar panel is in a shaded place or malfunctioning in any way, you will suffer electricity losses because of it.

2. Microinverters

Microinverters are the opposite of string inverters. Unlike string inverters, they are installed on each individual solar panel. With this, each inverter independently converts each solar panel’s DC electricity to AC electricity without interfering with each other.

Microinverters have, thus, removed the biggest disadvantage of string inverters. Even if one solar panel is in a shaded area or is malfunctioning, it will not cause you any electricity losses. While this is an advantage, microinverters are, nonetheless, on the expensive side.  

3. Power Optimizers

Lastly, we have the power optimizers - a sort of hybrid between string inverters and microinverters. In this case, an optimizer is installed on each solar panel.

This optimizer takes the DC from each solar panel, regulates it to an optimal voltage and current, and then sends it to a centralized inverter. The DC to AC conversion takes place in this centralized inverter.

With this, power optimizers offer you the same performance level as microinverters but with relatively economical pricing like the string inverter. Cool, isn’t it?

 

Practical Applications of AC

As we have already mentioned above, all residential electrical appliances are powered by AC. These include appliances such as lights, refrigerators, microwave ovens, coffee makers, computers, and laptops, among others. Commercial industrial machinery is also run by AC.

Therefore, the conversion of DC to AC through inverters is a necessary procedure. While it does incur a small loss of electricity, it is extremely small when considering that AC powers literally everything electronic.

In addition, it is the conversion of DC to AC that allows solar energy systems to integrate seamlessly with the existing electrical grid. The conversion of DC to AC and the device that brings this about (the inverter) is, thus, extremely important for you. This is especially so if you have or intend to have a solar power supply for residential or commercial purpose.

 

Considerations When Buying Inverter

When considering which inverter to buy, you need to keep in mind the size of your solar power supply, whether the solar panels are in a shaded area or not, and your budget.

If your system is relatively bigger, placed in a shaded area, and/or you are not tight on budget, microinverters or power optimizers would work better.

If you desire a budget-friendly option and your solar panels are placed in open sunlight, opting for string inverters or power optimizers would be better.

 

Benefits of Solar Power Supply Generators

Solar panels are the devices that produce solar power, but that is not all there is to a solar power supply. With solar panels and inverters, you also require a portable power station or a portable generator for home backup.

They store solar-generated electricity. You can then use this electricity when the Sun is no longer available, such as at night or in rainy weather. In addition, you can also go off-grid with their help.

There are various benefits of having a portable solar power station or an indoor generator for home, such as portability, reliability, and independence from the grid.

1. Portability

These devices are portable; you can easily carry them around with you if you want to go on a camping adventure. You will have unlimited electricity access no matter where you are.

2. Reliability

Whether you have an indoor generator for home, a generator for apartment, or a potable power station, they will offer you unlimited electricity. They are a reliable source, offering you electricity even in emergency situations.

3. Independence From the Grid

These devices equip you with the necessary devices needed to become independent from the grid. You can easily free yourself of reliance on traditional power sources. Tempting, isn’t it?

Conclusion

Overall, we now know that a solar power supply inherently produces DC power, but our home appliances are run by AC power. Thus, inverters are used to convert DC to AC. You can buy either the string inverter, the microinverter, or the power optimizer, according to your needs and requirements.

While solar panels produce electricity for you, they are limited to working only when there is sunlight available. Thus, it necessitates the use of a potable power station or a generator for apartment to store electricity.

You can then use this power when there are blackouts, you are out camping, or intending to go off-grid. You can buy these devices from Oukitel. They offer a range of portable solar power station and portable generator for home backup. So, be sure to check it out!
