Various terms such as 3 kw solar panel price, 3 kilowatt solar panel price, 3kw solar panel price in India with subsidy, and 3 kw solar plant price have also been covered to help all types of users.
What Is a 3kW Solar Panel System?
A 3kW solar panel system is designed to produce enough electricity to meet the needs of a small-to-medium family. Appliances like fans, lights, refrigerators, washing machines, TVs, and small air conditioners can be supported by this system.
Typically, around 12 solar panels of 250–300W each are used to make a 3kW system.
How Does a 3kW Solar Panel System Work?
When sunlight hits the solar panels, DC electricity is generated. This DC power is sent to an inverter, where it is converted to AC (alternating current), which is suitable for household use.
- In on-grid systems, extra power is sent to the grid and credits are received (net metering).
- In off-grid systems, batteries are used to store excess electricity.
- In hybrid systems, both grid and batteries are used, ensuring backup and savings.
Types of 3kW Solar Systems in India
| Type | Battery Backup | Grid Connection | Ideal For |
|---|---|---|---|
| On-grid | No | Yes | Urban homes with stable electricity |
| Off-grid | Yes | No | Rural areas with power cuts |
| Hybrid | Yes | Yes | Homes needing backup + bill savings |
What is 1kW Solar Panel Price with Battery?
The price of a 3kW solar panel system with battery in India usually ranges from ₹2,10,000 to ₹2,80,000, depending on the battery type (lead-acid or lithium-ion), brand, and installation quality. Battery-backed systems are typically off-grid or hybrid, and they’re ideal for areas with frequent power cuts or unreliable grid supply.
When a lithium-ion battery is included, the cost may go higher but offers longer life and better performance. Lead-acid batteries are more affordable but need more maintenance. On average, a 3kW solar system with battery storage can run basic home appliances like lights, fans, fridge, and a small water pump for several hours daily.

3kW Solar Panel Price in India with Subsidy
3kW Solar Panel Price in India with Subsidy
A 3kW solar panel system in India typically costs between ₹1,50,000 to ₹2,10,000 without subsidy, depending on the brand, type (on-grid or off-grid), and installation quality. With government subsidy under the PM Surya Ghar Yojana, homeowners can get up to 40% subsidy for systems up to 3kW. This reduces the effective 3kW solar panel price in India with subsidy to around ₹90,000 to ₹1,20,000. On-grid systems are more commonly subsidized. These systems can generate about 12–15 units of electricity per day, helping reduce monthly bills significantly. The subsidy is directly credited to the installer, so users pay only the reduced amount. This makes solar more affordable for middle-class households. Installation must be done through government-approved vendors.
