Off-Grid Solar Rooftop Systems
Most of the industries and factories are characterised by heavy machinery and all-day shifts, which means they would require uninterrupted electricity throughout the day.
Since the sun does not shine all the time, energy production through a solar system terminates after sunset.
An off-grid system overcomes this disadvantage by being armed with a battery back-up.
Here, unlike in a grid-tied system, the energy produced is stored in the batteries, thus eliminating the possibility of power outings.
At an unlikely event when the batteries run low, engine generators can be used as a back up as well.
However, they just add up to the overall cost and are not very widely used.
Off-grid systems provide energy independence.
So what makes off- grid solar systems beneficial?
However, these systems come with their fair share of disadvantages as well. They are as follows
Inclusion of batteries add up to the capital investment in the system.
Extra space for battery storage.
The inclusion of complex components makes maintenance difficult and expensive.
Such a system is complex to install.
- It is a stand-alone system, making the industry independent of the utility grid.
- Power supply throughout the day.
- Highly efficient.
