How Much Does a Solar Inverter Cost? The
Choosing the right solar inverter is a crucial step in building an efficient and cost-effective solar system. By understanding the factors that influence
Example Calculation for 6 kW Installation: At the average rate of $0.28 per watt, an inverter for a 6 kW system would cost around $1,100. If the inverter is priced at the higher end ($0.50 per watt), the cost for the same system would be about $1,650.
We will walk you through the cost, size, and practicality of a 6kW system before you decide to buy. How much does an average 6kW solar system cost? Based on the average cost of solar in 2025, a 6 kW solar system in the U.S. will cost about $18,000 With the 30% federal tax credit, the solar system price drops down to about $12,000.
Most solar panel contractors charge around $50 to $100 per hour. You may save $1,000 to $2,500 up-front by choosing a string inverter over a microinverter or hybrid inverter. A solar inverter costs $2,000 on average, with prices often ranging from $1,000 to $3,000. That said, some homeowners spend as little as $800 or as much as $5,000.
System size – Your inverter's input-wattage rating should be close to your solar panel system's output rating. U.S. residential solar panel systems typically fall in the 5 kilowatt range. Efficiency – The industry standard for peak efficiency is 97%. More efficient models often cost more.
