Off-Grid

A system completely independent from the utility grid: all the energy consumed must be produced (solar panels) and stored (batteries). Recommended for remote locations or where grid connection is difficult, expensive, or unreliable.

Advantages

Total independence from the utility grid.
Ideal for remote locations.
Full control over the system.
Can be more cost-effective long term if grid connection is expensive or unfeasible.

Considerations

Higher upfront cost due to large battery and inverter requirements, plus optional generator.
Requires precise sizing of daily consumption and desired autonomy (how many days without sun the system should withstand).

Main Components

Solar panels.
Charge controller.
Battery bank.
Inverter/charger.
Optional backup system (diesel or alternative generator) for long periods without sun.
Electrical distribution, proper wiring, structural supports, and electrical protections.
System monitoring: solar production, battery bank status, and consumption.
