Solar inverter FAQs
AC electricity is the type of power that comes out of your home’s sockets and powers your appliances. AC power constantly switches between positive and negative current as it travels. DC electricity is the current produced by your solar panels when they capture the sun’s energy and moves in a straight line. Solar inverters are in charge of converting DC into AC electricity for use in your home.
A solar inverter is an essential part of your residential solar panel system. If you don’t have an inverter, your solar panels will only produce DC power, which can’t be used in your home.
The typical cost for an inverter for a mid-sized solar system is $1,000 to $1,500. If you have a larger system, prices for inverters can rise above $2,000. Factors impacting your inverter’s price include warranties, the manufacturer, and type of inverter.
Most inverter warranties cover defective parts, poor manufacturing, and unexpected damage. However, the terms of each warranty will be specified by the manufacturer. Warranties typically last between five and 10 years, but you can extend them at an extra cost.
