Introduction to Photovoltaic Systems
A photovoltaic (PV) system changes sunlight into electricity. It uses solar cells, which are made of special materials. These materials turn sunlight into an electric current.
Overview of Solar PV Systems
Solar PV systems take energy from the sun and turn it into power. They have solar panels, inverters, and other parts that help with this. These systems let us use the sun’s power at home, in businesses, or for industry needs.
How Photovoltaic Systems Work
The core of how solar PV systems work is the photovoltaic effect. This effect makes electricity when sunlight hits the solar cells’ material. The excited electrons start moving, creating an electric current.
This current is direct current (DC). An inverter changes it into alternating current (AC). This is the kind of current houses and buildings use. It can also be sent through the electric grid to others.
Solar PV Array
At the center of a photovoltaic system is the solar PV array. It’s a set of solar panels that work together. These panels create electricity from the sunlight. Every solar panel has many solar cells inside. These cells are usually made from silicon or other special materials. They change sunlight into electric power using a process called the photovoltaic effect.
Solar Modules and Solar Cells
The solar modules, or solar panels, are key parts of the PV array. They are built to last and give power for many years. By putting lots of solar modules together, the PV array can fit the energy needs of homes, businesses, or factories.
Module Mounting Structure
The module mounting structure is very important for the solar PV array to work well. It holds the solar modules in place. This makes sure they catch lots of sunlight every day. The way the mounting structure is set up can change. It can be on the ground or on a roof. Sometimes, it’s built right into a building. It all depends on the project’s space and needs.
Inverter
The inverter is key in a solar system. It changes the DC electricity from solar panels into usable AC. This lets you power your home’s devices and appliances.
Converting DC to AC Power
The solar inverter changes sunlight into energy you can use. It takes the DC power from solar panels and makes it AC power. This is important because most things at home and the grid run on AC.
Inverter Efficiency and Safety Features
Today’s inverters are made for top efficiency and safety. They can be over 95% efficient. This means less energy is lost. They also offer safety tools to protect the system and grid, like ground fault protection and arc fault detection.
what are the components of a pv system
A photovoltaic system includes the solar PV array and inverter. It may also have a charge controller and a battery bank. These are for storing energy.
The charge controller manages the power flow from the solar panels to the batteries. It makes sure the batteries charge well and stay safe from getting too full or too low.
Charge Controller Types
Two common types of charge controllers are used in these systems. There is the pulse-width modulation (PWM) type and the maximum power point tracking (MPPT) type. PWM controllers are simpler and cheaper. MPPT controllers are more advanced. They make the solar energy system work better and the batteries last longer.
Battery Bank and Energy Storage
The battery bank stores the extra solar energy. This stored energy is used at night or when it’s cloudy. Its size and type depend on how much energy the house or building uses. It also depends on how much the solar panels can produce.
Fenice Energy has been providing clean energy solutions for over 20 years. They help with solar, backup systems, and EV charging. They can assist in picking the best charge controller and battery bank for your needs. This ensures your system works well and is reliable.
Utility Meter and Grid Connection
Every home or building with a solar system includes a utility meter. This meter measures how much electricity is used and created. It connects to the solar system. Then, it shows the electricity use from the grid and the surplus energy sent to the grid. This tracking helps homeowners and businesses get credit for extra solar energy.
The utility meter and the solar system’s grid connection work together. This setup lets solar electricity and the local grid work as one. When solar panels don’t produce enough power, electricity can be taken from the grid, like on cloudy days or at night. If more electricity is made than needed, it goes back to the grid. This can lower the user’s electricity costs.
Fenice Energy is a go-to for clean energy, offering solar, backup systems, and EV charging. The company has over 20 years in the field. They excel at connecting systems to the grid and meters. This expertise ensures a hassle-free process. It makes solar systems truly beneficial for those in India.
Types of Solar PV Systems
Photovoltaic systems are mainly grouped into three types: grid-tied, off-grid, and hybrid systems. Each type connects differently to the electrical grid.
Grid-Tied Systems
Grid-tied solar PV systems are the most used. They link to the grid and generate electricity from solar panels. They send extra power back to the grid. This cuts down electricity costs for homes and businesses. Also, these systems do not need batteries. They use grid electricity when solar power is lacking.
Off-Grid Systems
Off-grid solar PV systems work independently from the grid. Perfect for far-away places without reliable power grids, they provide and store their own power. To ensure constant power, they use a battery bank. This stores solar energy for times with little sunlight.
Hybrid Systems
Hybrid solar PV systems merge grid-tied and off-grid features. They are connected to the grid but have batteries and can run on their own. They use grid and solar power interchangeably. This way, they ensure power even during blackouts or when grid power isn’t available.
| System Type | Grid Connection | Battery Storage | Suitability | Approximate Cost (INR per kW) |
|---|---|---|---|---|
| Grid-Tied | Connected to the grid | No battery storage | Suitable for homes and businesses with reliable grid access | 50,000 – 60,000 |
| Off-Grid | Completely independent of the grid | Requires battery storage | Suitable for remote locations or areas with limited grid access | 80,000 – 100,000 |
| Hybrid | Connected to the grid with backup off-grid capability | Includes battery storage | Suitable for homes and businesses that require a reliable and flexible power solution | 70,000 – 90,000 |
