Choosing A Solar Panel System: Off-Grid Or Grid-Tied

When it comes to DIY solar panel installation, there are two primary types of systems: off-grid and grid-tied.

An off-grid system operates independently, is not connected to the utility grid, and requires a battery bank for energy storage.

A grid-tied system remains connected to the utility company, providing a backup in case your solar system doesn’t generate enough power and allowing excess energy to be sent back to the grid for credits or compensation.

For off-grid solar projects, a battery backup system is essential to store excess energy generated during the day for use during the night or periods of low sunlight. A solar battery serves as a reservoir for self-generated power, ensuring a continuous and reliable energy supply. This is particularly advantageous for off-grid systems in remote locations, cabins, RVs, or those seeking complete energy independence—which are typically those considering DIY solar.
