Basics of On-Grid Solar SystemsAn on-grid solar power system connects directly to the public electric grid, allowing it to
work in tandem with the grid. Instead of relying on a generator or battery, you can harness
clean solar energy during the day for your home or office. When the sun sets or it gets dark,
the system automatically draws energy from the grid to ensure you have a continuous power
supply.
If your on-grid system produces excess energy, you can send it back to the grid through net
metering and receive credits on your electricity bill. This feature is a key reason why on-grid
solar systems are increasingly popular for homes and Commercial & Industrial Solar
Panels in India.

4. How On-Grid Solar Works 1.Solar Energy Collection – First the Photovoltaic panels capture sunlight and convert it into direct
current (DC).
2.Conversion to Usable Power – Then the connected solar inverter changes DC to AC for household
and commercial use.
3.Powering Your Space – On conversion the AC electricity starts running all your appliances, lights,
or factory equipment.
4.Net Metering & Grid Export – Now, after this if there are any extra units of electricity they flow
back to the grid and you can avail credit benefits from this.
5.Automatic Grid Support – At night or during heavy usage, power is drawn from the grid. So, you
can get an uninterrupted power supply at all times.

5. Advantages of On-Grid Solar Systems
Lower electricity bills and strong net-metering benefits.
No batteries needed, keeping costs down.
Simple maintenance compared with off-grid setups.
Ideal for cities with stable grid supply.
Disadvantages Of On-Grid Solar Systems
Shuts down in power cuts unless paired with a battery backup.
Depends on grid availability.

6. Solar Energy
Off-Grid Solar SystemAn off-grid system is self-sufficient and does not rely on the utility grid. The system
captures the surplus solar energy and stores it in batteries, making it ideal for far-off
locations or rural places that do not have reliable power service.

7. How Off-Grid Solar Works 1.Solar Generation – First the PV panels of your solar power system capture sunlight and then
convert it into DC electricity.
2.Charge Regulation – Once the power is converted into DC electricity, then it is forwarded to a
controller preventing over-charging in the batteries of your solar power system.
3.Battery Storage – After charging the deep-cycle batteries of the solar power system hold the
excess power for night or cloudy days for consistent and undisturbed supply of energy.
4.Power Conversion – One the energy supply is sorted the solar energy system’s inverter converts
stored DC electricity to AC for various appliances and several purposes.
5.Complete Independence – Finally when the energy is converted into AC electricity it fulfills all the
energy needs of the space without any need for a grid.

8. Advantages of Off-Grid Solar Systems
Total energy independence.
Best for rural or remote properties.
Provides backup during outages.
Disadvantages of Off-Grid Solar Systems
Higher upfront cost due to batteries.
More maintenance and periodic battery replacement.

10. Cost & Subsidy Overview
On-Grid Systems: Around ₹45,000–₹65,000 per kW in India, minimal operating expense, and
quick payback (4–6 years) via net-metering credits.
Off-Grid Systems: ₹90,000–₹1,50,000 per kW because of battery storage; higher lifetime
maintenance.
Subsidies: Residential on-grid solar installations are eligible for up to a 40% subsidy (up to 3 kW)
and nearly 20% subsidy for residential systems sized 3-10 kW under India’s National Solar
Mission. Off-grid systems generally do not receive these benefits.
Choosing the Right Solar System
Urban or Semi-Urban: Reliable grid? Go on-grid for savings and easy maintenance.
Remote or Rural: Choose off-grid if grid power is unavailable or unstable.
Hybrid Option: Combines grid connection with batteries for the best of both worlds.

11. Why Contendre Solar Panels?
Selecting quality equipment is as important as choosing the system type. As a leading solar
panel manufacturer, Contendre delivers high-efficiency modules suited for Indian weather
and perfect for solar for home projects or large-scale commercial & industrial solar panels
installations.
Selecting an on-grid solar system in India, a fully off-grid system, or a hybrid alternative, transitioning to
solar energy leads to lower bills and a more environmentally friendly future. Assess your site, your budget,
and your energy requirements and, more than anything, work with a reputable solar panel
manufacturer (like Contendre), so that you can be sure your money will provide you with clean and
reliable energy for the long term.
