A solar rooftop system typically includes solar modules, solar inverters, and electrical components like meters and cables. Excess electricity generated is fed back into the grid, and the owner’s account is credited as per prevailing regulations.

The capacity of a solar system depends on factors like your load requirements, available shadow-free space, and sanctioned load. On average, a 1 kW system can cover a monthly electricity bill of around Rs. 1000.

Solar modules rely on silicon wafers to convert sunlight into electricity. When exposed to sunlight, these semiconducting wafers release electrons, creating a flow of Direct Current electricity—a sustainable power source harnessed from the sun.

Grid-connected solar rooftop systems do not produce electricity during a grid outage. Systems equipped with batteries can provide backup and generate electricity using solar energy when the grid is down. More details can be found in the Products Section.

No, solar electricity isn’t wasted when unused. Excess solar electricity generated during the day is exported to the grid. At night, when solar generation is absent, any needed electricity is imported from the grid. Meters record this exchange, ensuring you’re credited for excess generation as per state policies and charged only for net consumption.

Yes, even after installing solar modules, you may still need government electricity supply, especially in a grid-connected solar system. Here’s why:

1. Intermittent Solar Generation: Solar power generation is dependent on sunlight. It generates electricity during the day when the sun is shining. At night or during cloudy days, solar generation is minimal or absent. Therefore, you’ll need the grid to provide electricity during periods of low or no solar generation.

2. Energy Consumption: Your energy consumption may exceed what your solar system generates at certain times, such as during high-load periods or when multiple appliances are in use simultaneously. In such cases, the grid can supply the additional electricity you need.

3. Backup Power: Grid-connected systems typically do not provide backup power during grid outages unless they are equipped with batteries. If you experience a power outage, government electricity supply is essential to keep your home or business running smoothly.

4. Excess Energy Export: In many grid-connected setups, excess electricity generated by your solar system can be exported back to the grid. This energy can be credited to your account or even earn you incentives in some regions.

• On-Grid: These systems are connected to the grid and can export excess electricity. They don’t provide backup during grid outages.

• Off-Grid: These systems are independent and store excess energy in batteries for use when the grid is down. They’re ideal for remote areas with no grid access.

• Hybrid: Combining aspects of both on-grid and off-grid systems, hybrids offer grid connectivity and backup power through batteries, providing flexibility and reliability.
