While there are three types of solar power systems (on-grid, off-grid, and hybrid), they all operate on
the same fundamental principles.
The photovoltaic (PV) effect is used by solar panels to convert solar energy or sunlight into direct current (DC) electricity.
This DC electricity may then be stored in a battery or transformed into alternative current (AC) power by a solar converter, which can then be utilized to power your household appliances.
Excess solar energy may be released back into your public electricity grid, giving you with credits on your energy account as well as lower electricity bills, depending on the type of solar power system employed.
In this post, we will examine the differences, benefits, and drawbacks of two of the most common types of solar power systems utilized in Solar Company in Kanpur:
On-grid solar is sometimes referred to as a 'grid-feed' or 'grid-tie' solar system.
Off-grid solar is frequently referred to as a stand-alone power system' (SAPS)
On-grid solar power systems
By far the most prevalent and commonly utilized solar system for homes and businesses in Australia is on-grid.
These systems, which typically employ conventional solar inverters and are installed on top of the roof,
However, most individuals' major attraction to on-grid solar systems is that they are linked to your local utility's GRID.
This means that any surplus solar power you create is exported back into your local power grid, allowing you to get a 'feed-in-tariff' (FiT) or accrue credits that you can payout at the end of the year; through a procedure known as 'net metering.'
This on-grid system is what most residential houses will adopt since it protects you if your solar system under or over-produces. Essentially, your electric utility provider serves as your battery storage facility.
The Benefits of On-Grid Systems
You do not need to purchase an expensive battery backup system to store any surplus energy; this utility is a battery in and of itself.
You will not need to make any changes to your lifestyle or methods of energy conservation.
Disadvantages of on-grid systems
They cannot generate solar energy and cut your electricity cost at night or when there is no sunlight.
They give you less of a reason to save energy!
Off-grid solar power systems
Off-grid solar systems are not linked to the local power grid and so require their own battery storage solution, in addition to the solar panels and inverter.
The system's generated electricity is utilized to power the home and appliances, with any remaining power saved in batteries for use later in the evening or on a rainy day.
Off-grid systems are frequently required in remote areas that are too far away from the local electricity grid. As a result, they must be designed to generate enough power throughout the year and have enough battery capacity to meet the requirements of the premises – even in winter when there is less sunlight.
The Benefits of Off-Grid Solar Systems
If you utilize an off-grid system, you are completely self-sufficient in terms of energy consumption because you are not connected to your local grid's power system or utility company in any manner.
These systems are useful for scalability as your energy requirements vary over time.
They encourage you to utilize your power more efficiently, which is beneficial for the environment.
Off-grid System Disadvantages
Off-grid systems necessitate the purchase of a backup battery, which can be big and costly.
Solar battery systems require routine maintenance.
Because the system is not connected to the grid in any manner, off-grid solutions do not include the feed-in tariff.
