Rooftop Solar System FAQs – On-Grid, Off-Grid, Hybrid & Net Metering
Find answers to the most frequently asked questions about rooftop solar systems, including on-grid, off-grid, and hybrid solar solutions, net metering, system performance, warranties, and maintenance. This section helps you understand how solar energy systems work and which option is best for your home or business.
Rooftop solar systems are categorized based on grid connectivity and energy storage. There are three main types:
- 1. On-Grid Solar System (Grid-Tied)
- 2. Off-Grid Solar System
- 3. Hybrid Solar System
Summary Comparison:
| Feature | On-Grid | Off-Grid | Hybrid |
|---|---|---|---|
| Grid Connection | Yes | No | Yes |
| Power Backup | No | Yes | Yes |
| Battery Required | No | Yes | Yes |
| Export to Grid | Yes | No | Yes |
| Cost | Low | Medium | High |
An on-grid solar system is connected to the electricity grid and does not require batteries. Excess solar power is exported to the grid, reducing your electricity bill.
An off-grid solar system works independently without grid connection and uses batteries to store energy for later use.
A hybrid solar system combines on-grid and off-grid features, allowing both battery storage and grid export.
Net metering is a system where excess solar energy exported to the grid is credited against your electricity bill.
A rooftop solar system is installed on building roofs to generate electricity from sunlight and reduce electricity bills.
kWp is the peak power capacity of a solar system, while kWh is the actual energy generated or consumed.
Solar panels typically last 25–30 years, inverters 8–10 years, with manufacturer warranties included.
