On-Grid Solar
Systems in Warangal
On-grid solar systems are the most cost-effective way to reduce electricity bills by connecting directly to the power grid. Sell excess energy back to the grid through net metering and enjoy 50-70% reduction in monthly electricity costs with zero battery investment.
On-Grid Solar System Flow
Understand how on-grid solar systems work and how electricity flows from panels to your home and back to the grid
Solar Panels
Solar panels convert sunlight into DC electricity during daylight hours
Inverter
Inverter converts DC power to AC power for home use
Your Home
Solar power runs appliances and reduces grid consumption
Grid Connection
Excess power exported to grid earns net metering credits
Benefits of On-Grid Solar Systems
Lowest Cost Per Watt
On-grid systems have the lowest upfront cost since they don't require expensive battery storage, making solar accessible to more homeowners and businesses.
Net Metering Benefits
Export excess electricity to the grid and earn credits that offset your nighttime consumption, effectively using the grid as a virtual battery.
Unlimited Power Supply
Grid connection ensures continuous electricity even when solar generation is low, with no need to manage battery charge levels.
Zero Maintenance
Without batteries, on-grid systems require minimal maintenance - just occasional panel cleaning and annual inverter checks for optimal performance.
Quick ROI
Lower initial investment and higher savings from net metering result in faster return on investment, typically 3-4 years in Telangana.
Maximum Efficiency
All solar energy generated is either consumed immediately or exported to grid - no energy wasted in battery conversion losses.

On-Grid Solar FAQs
On-grid inverters automatically shut down during power cuts for safety reasons (anti-islanding protection). This prevents electricity from flowing back to the grid and endangering utility workers. Your solar system will not provide backup power during outages unless you add a battery backup with a hybrid inverter.
Net metering allows you to export excess solar electricity to the grid and receive credits that adjust against your consumption from the grid. In Telangana, net metering is available for residential, commercial, and industrial consumers under gross/net metering policy. Your bi-directional meter tracks both import and export, and billing is done on a net basis.
In Telangana, residential consumers can install solar systems up to their sanctioned load or 10 kW (whichever is lower) under net metering. Commercial and industrial consumers can install up to their contract demand. Larger systems may require open access approvals.
On-grid solar systems in Warangal typically have a payback period of 3-4 years depending on your electricity consumption pattern, system size, and tariff rates. After payback, you enjoy free electricity for the remaining 20+ years of system life, resulting in significant long-term savings.
Yes, on-grid solar is excellent for agricultural pumps if you have grid connection. Pumps typically run during daytime when solar generation is maximum, resulting in direct use of solar power and minimal grid dependence. Any excess generation can be exported through net metering for additional income.
