What Is a 3kW Solar Panel System?
A 3kW solar panel system is a rooftop solar setup capable of generating around 12 units (kWh) of electricity per day under ideal sunlight conditions. It is suitable for:
- Small to medium-sized households
- Homes with monthly electricity consumption of 300–400 units
- Small offices or shops
Typically, a 3kW system consists of 8 to 11 solar panels, depending on panel wattage (330W–550W).

How Much Electricity Does a 3kW Solar System Generate?
Electricity generation depends on sunlight availability, roof direction, and shading. On average in India:
- Daily generation: ~12 kWh
- Monthly generation: ~360 kWh
- Yearly generation: ~4,320 kWh
This output is sufficient to run most basic household appliances comfortably.
How Does a 3kW Solar Panel System Work?
A 3kW solar system works on photovoltaic (PV) technology.
Here’s a simple explanation:
- Sunlight falls on the solar panels
- Solar cells absorb photons from sunlight
- This creates Direct Current (DC) electricity
- A solar inverter converts DC into Alternating Current (AC)
- AC power runs your home appliances
This process happens silently, without fuel, smoke, or pollution.
