Technical Rooftop Solar FAQs
Explore answers to the most common technical questions about rooftop solar systems, including solar panel performance during night and power cuts, solar inverter working, maintenance requirements, monitoring systems, battery backup, weather resistance, and heavy electrical load handling for residential and commercial solar installations.
No, a rooftop solar system does not generate electricity during the night because solar panels require sunlight to produce energy.
However:
- Excess solar power generated during daytime can be exported to the electricity grid through net metering.
- During nighttime, electricity can be imported from the grid as normal.
- Hybrid and off-grid solar systems with battery backup can store solar energy for nighttime usage.
It depends on the type of rooftop solar system installed:
| System Type | Works During Power Cut? | Notes |
|---|---|---|
| On-Grid Solar System | No | Automatically shuts down during grid failure for safety reasons |
| Off-Grid Solar System | Yes | Uses battery storage and works independently from the grid |
| Hybrid Solar System | Yes | Can switch between solar panels, battery backup, and grid supply |
On-grid rooftop solar systems automatically shut down during power cuts due to a safety feature called anti-islanding protection.
This protects utility workers repairing the power grid from accidental electric shock caused by electricity exported from solar panels.
Rooftop solar systems require very low maintenance, but regular cleaning and inspections help maintain optimal solar panel efficiency.
Routine Solar Panel Maintenance:
- • Panel Cleaning: Clean solar panels every 15–30 days depending on dust, pollution, and bird droppings.
- • Visual Inspection: Check for loose wiring, corrosion, or shading caused by nearby trees or structures.
Annual Solar System Maintenance:
- • Electrical inspection of inverter and wiring
- • Monitoring system performance and energy generation
- • Re-tightening mounting structure bolts and electrical connections
Pro Tip:
Use soft water and a non-abrasive cloth for cleaning solar panels. Avoid pressure washers or harsh chemicals.
Our rooftop solar systems include a remote monitoring platform through a mobile app or web dashboard.
You can monitor:
- • Daily, weekly, and monthly solar energy generation
- • Real-time solar power output
- • Fault alerts and underperformance notifications
- • Net metering import and export statistics
Benefits of solar monitoring:
- • Detect performance issues early
- • Optimize electricity consumption
- • Compare expected and actual solar generation
Yes, rooftop solar systems are designed to withstand various weather conditions including rain, wind, and high temperatures.
- Rain: Solar panels are water-resistant and mounting structures are corrosion-resistant.
- Wind: Solar systems are engineered to handle high wind speeds, often up to 100 km/h or more.
- Heat: Solar panels are tested to operate efficiently even under high temperatures.
Proper solar installation and site assessment are important for long-term durability and safety.
Our solar panels typically include a 25-year warranty and a lifespan of around 30 years.
Solar inverters usually come with an 8-year warranty and may require replacement after 8–10 years depending on usage.
If any component fails:
- • Contact our technical support team immediately
- • Warranty-covered replacements are generally free
Yes, heavy electrical appliances such as air conditioners, submersible pumps, refrigerators, and industrial loads can be used with an on-grid rooftop solar system.
The solar system works together with the electricity grid to supply the required power at any time.
Over time, the rooftop solar system offsets your electricity consumption and significantly reduces your electricity bills.
