The average solar panel system in 2024 costs about $31,558 before factoring in tax credits and solar incentives. The Residential Clean Energy Credit is part of the Inflation Reduction Act and offsets the total cost of solar panels by 30 percent when you file your annual federal tax return.
The average 5-kilowatt (kW) solar panel system is $14,210 before considering any financial incentives. However, a typical American household needs a system closer to 10 kW to adequately power their home, which costs $28,241 in 2024. That price effectively drops to $19,873 after considering the full federal solar tax credit.
Depending on which state you live in, your average 6kW solar panel system will cost between $10,200 and $15,200 to install after accounting for the 30% solar tax credit. However, we know that every home has its own energy demands, and prices for solar panels can quickly increase or decrease based on the size of your system.
Solar panels can generate major savings if you're trying to reduce your electricity costs, carbon emissions or both. The primary factor in determining whether or not solar panels are worthwhile for you is the cost you're currently paying for electricity. The higher your electricity costs, the more a solar panel system will save you in the long run.
