Everything You Need to Know About On-Grid Solar Systems in India
Powered by Techno Green Solar
As electricity prices continue to increase every year, homeowners, businesses, industries, and commercial establishments are rapidly shifting towards on-grid solar systems to reduce electricity bills and achieve long-term savings. An on-grid solar system is one of the most affordable and efficient renewable energy solutions available in India.
Techno Green Solar is a trusted Solar EPC company providing complete solar solutions for Residential, Commercial, Industrial, Institutional, and Government projects across India. From site survey and design to installation, subsidy assistance, net-metering, and maintenance, we deliver complete end-to-end solar solutions with premium quality components and professional installation.
What is an On-Grid Solar System?
An On-Grid Solar System, also called a Grid-Tied Solar System, is directly connected to your local electricity grid. It generates electricity during the daytime using solar panels and powers your home or business. If your solar system produces more electricity than you consume, the excess electricity is exported to the government electricity grid through Net Metering.
During nighttime or when solar production is low, electricity is automatically imported from the grid, ensuring uninterrupted power supply.
Unlike off-grid systems, on-grid solar systems do not require batteries, making them more economical, efficient, and easier to maintain.
Key Benefits
✔ Up to 90% reduction in electricity bills
✔ Government subsidy available for residential users
✔ Net Metering facility
✔ Low maintenance
✔ 25+ years of panel life
✔ Faster Return on Investment (ROI)
✔ Environment-friendly energy generation
What Are the On-Grid Solar System Components?
A complete on-grid solar system consists of several important components working together.
1. Solar Panels
Solar PV panels capture sunlight and convert it into DC (Direct Current) electricity.
Premium brands include:
- Waaree
- Vikram Solar
- RenewSys
- Adani Solar
- Tata Power Solar
Panel lifespan typically ranges between 25–30 years.
2. Solar Inverter
The inverter converts DC electricity generated by solar panels into AC electricity used by household appliances.
Popular inverter brands:
- Sungrow
- Havells
- Growatt
- Solis
- Huawei
3. Net Meter
A bi-directional meter records:
- Electricity imported from the grid
- Electricity exported to the grid
This helps calculate your monthly electricity bill after adjusting exported units.
4. Mounting Structure
Galvanized Iron (GI) or Aluminum structures securely hold solar panels on rooftops while ensuring proper tilt for maximum sunlight exposure.
5. DC & AC Distribution Box
These protect the system against:
- Overload
- Short Circuit
- Lightning
- Voltage fluctuations
6. Solar Cables & Connectors
High-quality UV-resistant solar cables ensure safe and efficient transmission of electricity.
7. Earthing & Lightning Protection
Proper earthing protects both equipment and users while increasing system life.
How Does an On-Grid Solar System Work?
The working principle is simple yet highly efficient.
Step 1
Solar panels absorb sunlight and generate DC electricity.
↓
Step 2
The solar inverter converts DC electricity into AC electricity.
↓
Step 3
Your appliances use the generated electricity.
↓
Step 4
Extra electricity is exported to the electricity grid through Net Metering.
↓
Step 5
At night or during cloudy weather, electricity is automatically imported from the grid.
Everything happens automatically without any manual operation.
