Solar energy is an emerging technology replacing traditional electricity sources. PV systems are part of solar energy, and people often remain confused.
They wonder if the PV system is the same as solar energy, or is it different? Do you have the same questions?
Today, we will discuss what PV is in solar energy and how PV cells work. Let’s uncover the whole discussion.
What is PV in solar energy?
PV combines two words. One is the P that stands for Photo. It means light. V stands for volt, which means electricity.
The whole world refers to the Photovoltaic System. It is another work for solar energy. The PV energy system produces all its energy from solar PV cells.
How does a PV system work?
The working mechanism of the PV system is straightforward, as you can see from other systems. All you have to understand is the following steps.
Step 1: Sunlight Strikes Solar Panels
Solar panels have PV cells that generate electricity. Placing the solar panels in bright sunlight is necessary to generate energy. The PV cells are excited when the light falls on the solar panels.
Step 2: Electronic Phenomena
Once light strikes the solar cells, it excites electrons in the silicon. PV cells often have two layers.
- N-type layer (negative)
- P-type layer (positive)
Step 3: DC production
Electrons flow in one direction, producing direct current rather than alternating current.
Step 4: Inverter Functionality
DC is suitable only for a few devices. If you are looking for home appliances, AC voltage is the prime choice.
Since you get DC from solar energy, how do you convert it to AC? Some inverters come into action. They convert DC energy to AC.
Step 5: Energy Usage
Once AC voltage is available, appliances can smoothly utilize it. For AC-to-DC conversion, hybrid inverters can help store energy.
Components of the PV system
The Photovoltaic System comprises components such as inverters, solar panels, and batteries. Let’s understand all the components one-on-one.
Napelemek
Solar Panels are the primary and most crucial components. They are involved in energy production.
Solar Panels have PV cells integrated into their structure. When exposed to sunlight, the PV cells generate energy.
Inverterek
Home appliances rely more on the AC power. At the same time, the solar panels generate DC power. Inverters convert AC to DC. There are different types of inverters based on their conversions.
- AC inverters
- DC inverters
- Hibrid inverterek
Mounting Structures
Mounting structures are accessories for installing solar panels and inverters. They can include a range of products, such as:
- Fixed tilt (non-moving)
- Tracking (moves with the sun’s direction to increase efficiency)
Akkumulátor
Batteries are ideal choices for off-grid support. They allow excess energy to be stored in daylight. At night, there is no sun. At that time, batteries stored energy for the appliances as a backup supply.
Charge Controllers
Charge Controllers are the optimal devices, offering a comprehensive range of features. For example, they can maximize the energy production and ensure a reliable experience.
Types of PV Systems
There are three fundamental types of PV systems: grid-based and off-grid systems.
Let’s discuss them.
Grid System
Have you ever heard of net metering? It is the grid system that provides this facility. No batteries are used in this system. Solar systems generate energy, route it to the grid in excess supply, and take it back when no sunlight is available. The energy flow is from the solar system to appliances and the grid.
Off-grid System
Do you want energy independence and bypass all methods? An off-grid system is there at the top. You have to purchase batteries and route energy from the solar system to them for storage. If there is no sunlight, you can back it up with batteries and power your entire system.
Hybrid System
What if you get both systems combined? That is even better when you have to store energy or enjoy the perks of net metering. A hybrid system combines grid and off-grid facilities and gives you dual benefits.
Advantages of PV Solar Energy
PV solar energy is beneficial for several reasons. Here are a few discussed.
Clean and Sustainable
Solar energy comes from sunlight. At the same time, there are no fossil fuels diminished, produced, or burned. Therefore, it is a cleaner energy source that offers an endless supply. Being an eco-friendly és unlimited energy source, solar energy is in higher demand.
Low Operating Costs
You have to invest in solar panels and inverter systems. That is all you do. There is no need for a batteries if you don’t want them, or no need for a grid support. Such costs are low, offering buyers more affordable solutions.
Long Lifespan
Solar panels are robust and have stood the test of time. A good quality solar panel can produce energy for more than a decade. At the same time, maintenance can further improve the lifespan and make it an unbeatable quality.
Energiafüggetlenség
If you don’t want to rely on grid electricity, go for an off-grid system with batteries. It gives better control over the energy and offers energy independence. You can better support your system.
