How Much Do Solar Panels Cost? (Jan 2026)
Solar panels generate “free” electricity, but installing a system still costs money. A typical American household needs a 10-kilowatt (kW)
A 4kW solar system may be enough for a 2-3 bhk home with average electricity consumption. What does a 4kW solar system mean? A 4kW solar system is an electricity generation system connected to the local electricity board, producing an average of 16 units of electricity. How much does it cost to install a 4kW solar system?
Cost per kWh shows the lifetime cost of solar electricity by dividing your net system cost by total expected energy production over 25 years. This typically ranges from 6-8 cents per kWh, compared to current grid electricity averaging 16.44 cents per kWh nationally.
A 4kW solar system is an electricity generation system connected to the local electricity board, producing an average of 16 units of electricity. How much does it cost to install a 4kW solar system? The cost of a solar system depends on which model you choose: on-grid, off-grid, or hybrid. The average cost in the US is $11,400.
For a 4kW solar system, a battery of 5-6kW would be ideal. Battery storage is essential to increase energy cost savings. Battery storage stores energy consumption in hours for nights and outages and keeps your solar system productive when the grid is down.
