# Residential solar and battery case study in Santiago, Costa Rica

A homeowner reported that the monthly ICE bill fell from approximately $400 to approximately $100 after installation. The result is specific to this property and may not be typical.

## Installed system

- Solar array: 12 panels rated at 550 W each, 6.6 kWp combined
- Hybrid inverter: 12 kW power handling capacity
- Battery storage: 10 kWh

The home uses solar energy first and stores available energy in the battery. No electricity is sold to the grid. ICE supplies electricity when demand exceeds available solar and stored battery energy.

## Important context

The reported difference is approximately $300 per month, or $3,600 annualized if that difference remains consistent. Actual results vary with electricity consumption, weather, tariffs and system settings. A simple payback calculation also requires the installed project price.
