As a result, thousands of households and businesses in Vizag are now installing rooftop solar panels
Understanding a Solar Rooftop System in Vizag
A rooftop solar system converts sunlight into electricity using solar panels installed on your roof. It can be connected to the grid, work with batteries, or run independently depending on your energy needs.
Types of solar systems commonly installed in Vizag:
1. Grid-Tied Solar System
- Most popular option
- Requires no batteries
- Reduces electricity bills drastically
- Allows net metering
2. Hybrid Solar System
- Uses both grid and battery backup
- Suitable for areas with power cuts
- Higher cost but more reliability
3. Off-Grid Solar System
- Works entirely without the grid
- Uses batteries for storage
- Ideal for remote locations
Whichever option you choose, the performance depends heavily on proper design, quality components, and professional installation.
