What is the difference between On-grid and off-grid solar power?

If you’ve been doing your research on solar roofs, you’ve probably heard the terms “On-Grid” and “Off-Grid”

With the hundreds of terms and components of a solar roof, we know it can get confusing for a first time solar homeowner.

In this article, we break down the differences between the two popular solar system formats for you.


On-grid systems are more common in urban areas and big cities in Metro Manila such as Las Pinas, Quezon city, Paranaque, and even Pasig.

They’re called on-grid systems due to their connection to a power grid. It still has components bonded over traditional electricity. It is tied to your local utility’s grid.

It’s a popular choice among residential homeowners because they’re covered if the solar roof under or over produces energy. There are slimmer chances of experiencing power outage for On-Grid solar homes.

Being grid-tied is beneficial because you don’t have to buy an expensive battery back-up system to store any excess energy.

An on-grid system also allows you to get bigger savings through net metering,which means the excess energy is sent to your grid’s power company, allowing you to build credit and savings at the end of the year.


An off-grid on the other hand, means total independence from any power grid.

It means you are not connected in any way to your grid’s power system or utility company. This is a popular choice for people living in communities far from electric utilities. It’s also the choice among environmentalists who want to be their own electric company.
