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.
Mounting Options: Roof Mount Or Ground Mount
DIY solar installations offer flexibility in terms of mounting systems. Roof mount and ground mount are the two main options.
Roof-mounted solar arrays are popular due to their space-saving nature, making them an excellent choice for residential installations.
Ground mounts are ideal for those with ample space or when roof mount is not feasible. They are commonly used in off-grid solar projects or larger installations.
