Grid Tied Vs Off grid Solar
Grid-Tied Solar System
What is a Grid Tied Solar System?
A Grid Tied, also called an On-grid Solar system, is connected to the public electricity grid, does not need batteries, and uses either solar inverters or micro-inverters. The excess power produced is exported to the grid during solar power generation. At night, when your solar system does not produce electricity, your home draws electricity from the grid
Pros
Reduction in monthly electricity bills since you are still connected to the grid
Cons
You are still prone to power blackouts. This is because on-grid systems are unable to generate electricity during a blackout due to safety reasons
Note: For on-grid systems, a battery backup can be added to the system at a later stage if needed.
Off-grid Solar System
What is a Grid Tied Solar System?
An off-grid also known as a Standalone Solar system is not connected to the electricity grid. Therefore, the excess electricity is stored in a battery from where you draw your power at night when the solar panel is producing less electricity. Off-grid solar systems must be designed appropriately to generate enough power throughout the year and have enough battery capacity to meet the home’s requirements.
Off-grid systems are usually the best option for remote areas since the cost of extending the public grid is extremely highly
Pros
With or without the public grid, the off-grid system can power your property at all times
If you want to achieve energy independence, Off-grid systems are the way to go
Cons
It is more expensive since it requires the addition of batteries for backup
Grid-tied systems store energy in the power grid, while off-grid systems store energy in batteries.
