While we’re all aware of how solar PV systems convert daylight into power supply for our homes, let’s take a look at the different types of rooftop solar PV systems you can get for your daily electricity needs:

· Grid-Tied: This rooftop solar system proves to be the most cost effective for generating power if your building is connected to the main power network. It also reduces your energy bills significantly and emits lower CO2. However, this solar PV system can let you down during a power failure, as the inverter prevents the system from transmitting power to the grid, thus avoiding electrocution during repair work.

· Off-Grid: This system is pretty much self-sufficient, relying on its batteries to store and release power during times of inactivity, such as the night. This system does not work with grids and only has its battery backup or a diesel generator to support it. This is ideal for boats, temporary solutions, remote buildings or any other place that lacks mains electricity.

· Hybrid: This system gives you the best of both worlds, with the added benefit of freedom from power failure issues. It utilizes a grid connection to export power, using batteries for backup during power cuts. In addition, it works independently of fossil fuels, giving you access to clean energy generated in an eco-friendly manner.

· Grid-Interactive: This system works with the grid along with its battery backup or a diesel-fuelled generator in times of a power failure.  

The different systems use different combinations of inverters and batteries, but might carry a different terminology for different vendors. We suggest you take a complete tour of the functions offered by each system before making a decision. For further help on topic, don’t hesitate to get in touch with us today.
