On-Grid Solar Systems

An on-grid solar system (also called grid-tied or grid-connected system) is connected to the utility grid. It generates solar power during the day, which is first used to power your home/business. Any excess power is exported to the grid, and you get credit for it through net metering. When solar generation is insufficient (night/cloudy days), power is drawn from the grid.

Net metering uses a bi-directional meter that records both electricity imported from the grid and excess solar electricity exported to the grid. At the end of the billing cycle, you pay only for the "net" electricity consumed (import - export). If you export more than you import, the credit carries forward to the next month, with annual financial settlement for any remaining credits.

Standard on-grid solar systems automatically shut down during power cuts for safety reasons (anti-islanding protection). This is to prevent solar power from feeding into the grid while linesmen might be working on repairs. However, we can install hybrid systems or grid-tied systems with battery backup that provide power during outages.

Solar panels typically come with 25-year performance warranty (80% output guarantee after 25 years). Inverters have 5-10 year warranties. Mounting structures last 25+ years. The entire system requires minimal maintenance and can operate efficiently for 25+ years, making it a long-term investment with excellent returns.

Yes! Under the PM-Surya Ghar: Muft Bijli Yojana, residential consumers can get up to ₹78,000 subsidy for 3kW systems. For systems above 3kW, additional subsidy is available. We handle the complete subsidy application process and paperwork for our customers at no extra cost.

Approximately 100-120 square feet per kW of solar panels is required. For example: 1kW system needs 100-120 sq.ft., 3kW needs 300-350 sq.ft., 5kW needs 500-600 sq.ft. We conduct a free site survey to assess your available roof space and recommend the optimal system size.

On-grid solar systems require minimal maintenance. Basic requirements include: 1) Periodic cleaning of panels (every 2-3 months), 2) Checking for shading issues, 3) Monitoring system performance via app, 4) Annual professional inspection. We provide 5-year comprehensive maintenance packages for complete peace of mind.

Yes, on-grid systems are easily expandable. You can add more solar panels and upgrade the inverter capacity as your energy needs grow. We design systems with future expansion in mind and provide upgrade options at any time. Additional net metering approval might be required for significant capacity increases.
