What is an Off-Grid Solar System?
An off-grid solar system (also called standalone solar) is a self-sustaining power solution that is not connected to the CEB or LECO grid. It consists of:
- Solar Panels – Capture sunlight and generate electricity.
- Battery Storage – Stores excess energy for use at night or during cloudy days.
- Solar Inverter – Converts DC electricity from panels into AC power for appliances.
- Charge Controller – Regulates the energy flow and protects the batteries from overcharging.
Who Needs an Off-Grid Solar System?
- Homes in rural or remote areas where grid access is limited or unavailable.
- Businesses and farms looking for uninterrupted power supply.
- People who want energy independence and freedom from rising electricity costs.
