Broadly speaking, it costs about $19,400 for a 5-kW system and $38,800 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or higher quality panels, or if you have above-average energy needs. On the flip side, you can spend less if you want a smaller solar panel system or cheaper solar panels.
What other factors should I consider in addition to cost when buying solar panels?
The initial cost is a very important factor to consider, but whether it’s the most important for you depends on why you decided to go solar. In cities where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to keep in mind are the quality and durability of your solar panels.

Through these, you can receive compensation for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
