The US is now home to over three million solar photovoltaic (PV) system installations. Together, all those PV panels boast a capacity of 108.7 gigawatts (GW) of solar capacity. That’s enough to deliver clean, green, and renewable power to 18.9 million homes in the nation.
So, if you haven’t gone solar yet, now’s the best time to do so. For one, the 26% federal tax incentive is still up for grabs until 2022. Thanks to that credit, you can invest in the best solar panels without worrying too much about their cost.
Before shelling out money for your solar PV system, though, it’s best to have an idea of how they work first. That way, you’ll also understand what makes PV panels most suitable for your needs.
We’ll discuss the basics you need to know about residential solar panels in this guide, so be sure to read on.
How Do Solar Photovoltaic Panels Work?
A single solar PV panel consists of numerous, smaller units known as solar cells. The kind of solar cells used in each panel, in turn, determines the type of the PV panel.
There are three basic cell types: monocrystalline, polycrystalline, and thin-film.
Regardless of the cell type, though, all solar panels work by absorbing photons. Photons are radiant solar energy particles containing varying amounts of energy.
The photon energy makes electrons within a solar cell detach from their atoms. Those dislodged electrons then travel to the front-most surface of the cell. Meanwhile, the cells’ backside or bottom layer features a positive charge.
Those negative and positive sides then create a voltage potential. That makes them much like the negative and positive terminals of a battery.
Metal conductive plates and wires then harness the voltage from the interconnected cells. At that point, the electrons can flow like any other form of electricity. However, the cells generate only direct current (DC) electricity, which you can’t use yet.
That’s why you need to connect your entire solar PV system to an inverter. It’s a device that converts DC electricity into alternating current (AC) electricity. AC electricity is the form of energy used by electrical grids and the one you use at home.
What Are the Best Solar Panels Then?
One way to determine the best solar panels to get for your home is to factor in their performance rating. Performance refers to the amount of sunlight a panel can convert into electricity. That amount then dictates how efficient the panel is.
The higher the performance, the more sunlight the panel captures. The more captured sunshine, the more energy it can then convert into electricity. You, in turn, will have more “free” energy to use to power your home and electronic devices.
With that said, monocrystalline panels are the highest performance solar panels available today. That’s because they have the highest efficiency rating of all panel types, ranging from 15% to 20%. By contrast, polycrystalline panel efficiency ranges from 13% to 16%.
Thanks to their impressive efficiency, you’d need fewer monocrystalline panels. That makes them even more appealing to homes with limited space, be it on the roof or the ground. For the same reasons, though, they’re currently the most expensive PV panels in the market.
As such, some homeowners on a budget often gravitate toward the polycrystalline type. Although their efficiency rating is lower than monocrystalline, they do cost less. However, they’re still more efficient than thin-film panels.
On the other hand, thin-film panels may be your best choice if you have a very tight budget. They’re the least-efficient panels, which is also why they’re the least expensive. You’d need more of these panels, though, so you must also have lots of sunny spots on your property.
Application and Location Matter, Too
Producing electricity for indoor usage is the top reason homeowners install PV panels. However, it’s not the only way to utilize solar; you can also use it for outdoor lighting or a backup energy source. In such cases, though, you need to consider factors other than the type of solar cell or panel.
Ingress Protection for Outdoor Lighting
Let’s say you want to get a solar light for flagpole illumination or exterior lighting. Since the solar device will sit outside, it must have adequate ingress protection (IP). An IP rating of 65 to 67 is ideal, as this means the light can resist high winds, rain, sleet, and snow.
Solar Battery or Generator for Energy Storage
In 2020, utility customers in the US experienced a whopping 1.33 billion outage hours. That’s up 73% from the outage hours they dealt with during the previous year.
For that reason, it’s wise to consider using PV panels to store solar energy into a battery for later use. In this case, the best solar panels are those compatible or integrated with a solar generator. That way, the energy produced by the panels gets stored in the generator’s battery.
You can then use the stored energy in the battery to power your home during an outage.
Portability for Solar On-The-Go
If you like outdoor activities such as camping or hiking, you’d love portable solar kits. Like standard PV panels, the ones solar kits use also generate energy from the sun.
A key difference is that solar kits come with thinner, smaller, and foldable panels. You then connect the panels with USB ports to a battery pack and set them up anywhere with lots of sunlight. From there, you can plug in a portable LED lamp for lighting or recharge your electronics.
Invest in Quality Solar Panels for Long-Term Renewability
As you’ve learned, the best solar panels are often those with high-efficiency ratings. However, don’t forget other factors, such as where and how you’ll use them and your budget, too.
As a final tip, make sure your local solar installer gives you a system warranty of at least 25 years. That way, you can rest assured it will provide you with clean and green power for the next two and a half decades.

What’s the use of Through-Hole Technology in PCB Designing?
Greetings and welcome to today’s lecture. It is going to be a very interesting and interactive class about introduction to Through Hole Technology (THT) and Surface Mount Technology (SMT) that are applied in the process of designing the printed circuit boards. A PCB board is made up of properly designed circuits that are composed of connecting wires/paths and various electrical components. The electrical components are mounted on the board. In fact, they are fixed to the board. If the components are not fixed, then there will be no durability and this might lead to various losses that can be avoided. In the process of mounting these components, here is where the through-hole technology and the surface mount technology come in. They are very important processes in the design of printed circuit boards.
This is one of the methods used in the attachment of components to PCB during the manufacturing process.
- THT is the oldest among these PCB attachment methods.
- For so long time it was the standard method that was used in the PCB assembly process.
- In the 1980s, when the surface mount technology process was introduced in the field of the PCB assembly, so many people thought that the THT method will become extinct but that is not the case.
- THT is used in all kinds of PCB designs i.e. Single Layer PCB, Multilayer PCB, Flexible PCB etc.
Through-Hole Technology (THT) is the method used in the attachment of the PCB electrical components and elements in the PCB whereby the components being placed have long leads that are soldered into the board through the holes drilled.
- Dill holes on the PCB following the clients’ design.
- Select your components. They must have long leads. Also, remember components are on the design you have been given by the client.
- Place the components on the board and ensure that their leads are on the holes as defined in the design.
- Check that the components are in the positions described in the design to ensure that there will be no errors at the end of the process.
- Solder the terminals on the board accordingly. Ensure that the solder is on one side of the leads.
- Fill the other unsoldered side with flax.
Initially, this process was done manually hence it took a lot of time before coming up with a single complete board. Today, due to the changes in technology, it has become so easy to carry out the through-hole technology process. There are several automatic systems that aid out in the process and make it easy for the manufacturers, for example, the introduction of the automated insertion machines which actually helps in inserting the electrical elements into the drilled holes in the PCB before the soldering process starts.
We have talked about the electrical components being placed on the PCB boards through the through-hole. These components can be classified into two that is the radial leads components and the axial lead components.
From the image displayed, there is already something that is building up in your mind. Observe it well. Look at the leads. Can you see something common with the device leads? Yes of course. You are right! Both the two leads originate from the common side of the components. That is what we call a radial lead component. This method finds its application commonly in the packaging of the capacitors.
The components can be mounted either vertically or horizontally.
Let us have a look at that from the images below.
The vertical mounting of the Radial THT components.
on this method, the component is always place perpendicular to the board while the base is placed parallel to the board. complete joint. Soldering is done on one side of the terminal and the other side is filled with flax.
The horizontal mounting of the Radial THT components.
the contact body is fixed on the horizontal as you can see from the images. The leads exhibit a very nice bend and also spacing. This allows the proper filling of the solder on the component hence forming the strongest
- These are the most commonly used elements of the THT PCB methods components assembly.
- Here the leads of the components appear from opposite sides to each other. See what is in the attached image on the left.
Also, it can be classified as horizontal mounting and vertical mounting.
horizontal axial mounting method
Vertical axial mounting method.
Applications of the THT
- High voltage areas eg in the medical equipment.
- High mechanical stress devices eg military equipment.
- High power areas eg in the steam boilers.
- High temperatures operating devices eg in the nuclear plants.
- Prototyping and testing of components.
- The use of the THT method will ensure that you have a very strong mechanical bond compared to the SMTs components.
- THT bound components have high resistance to wear and tear and this is made possible by the use of the large soldering deposits at the terminals.
- The THT components are very easy to swap and repair the components hence they are the best for prototyping works.
- It is best suited for places where strong mechanical applications are needed such as aerospace and military equipment.
- Due to the drilling of the required holes, the production cost goes higher compared to the other method.
- Also, drilling of the holes requires some additional time, hence the THT method takes a longer time compared to other methods.
- This method limits the available routing paths for the multilayer PCBs because the drilled holes have to go through the given layers.
- The technology being used in the industrial mass production of the THT types of the PCB is less reliable compared to the other methods used.

How to Choose Your Gaming PC by PC Power Up?
Computers are one of the best tools that exist to play games, we know it well. So much so, that it is one of the preferred options for many users when it comes to gaming, even above consoles. And that the latter have hardware and software focused exclusively on playing games. Here are some things to consider about PC components that are available on PC Power Up and these are tested and suggest by experts.
The graphics card (GPU):-
This element is one of the most important in a gaming PC. It delivers the power needed to display games for the graphics part and, depending on its capabilities; you can enjoy one with a higher or lower resolution. We consider that today you need at least a GTX 1660 with 6giga of RAM but for light games like Fortnite a 1650 4giga will be sufficient. For those who want to enjoy recent games with Ray Tracing at 1080p, an RTX 2060 is the minimum.
The Processor (CPU):-
The processor is essential, since all the tasks of a PC necessarily pass through it. If it’s not fast enough, you might have the best graphics card on the market; it won’t use all of its power because the CPU isn’t keeping up. A good GPU / CPU combo is very important for playing; consider a 6-core for gaming and an 8-core for multitasking. You can find more information in our review of processors for gaming.
RAM Or Memory:-
For a good PC that holds up, you need at least 8GB of RAM, but now the standard is 16 Giga. The RAM is connected to the processor; it is used to store the information which will be sent to it. Too low RAM and that’s the tragedy everything is slowed down.
The Hard Drive:-
On a gaming PC, it is strongly recommended to have at least a 256GB SSD to install Windows and games. SSDs are much faster than hard drives (HDDs). A bonus HDD allows you to store the rest of your files or several games;
Keyboard and Mouse:
Not the most important thing, but a good quality gaming keyboard / gaming mouse combo can be decisive in your games;
This is essential because without a screen, no display, it makes sense. There are a multitude of screens, but be aware that TNs are more affordable and can be of high quality as well, especially for gaming; For small budgets we will therefore opt for a TN panel screen in 1080p and ideally ultra responsive with 1ms.
The Audio System:-
It will be entirely up to you, whether you prefer to play with headphones or with speakers. In this second case, there are PC speakers to be connected, or you can take advantage of those integrated into certain screens (but the quality is often lower).
Wired Network and Wi-Fi:-
To play, it is necessarily preferable to have an Ethernet port on your motherboard. But if you cannot stretch a cable from your box to your PC, opt for a quality Wi-Fi card.
