How much does a solar inverter cost?

A solar inverter costs $1,500 to $3,000 total on average for a medium-sized solar-panel system installation. Solar inverter prices depend on the size and whether it's a string inverter, microinverter, or hybrid model. String inverter systems cost less up front, but systems using microinverters last longer.

What is the best solar inverter?

The best solar inverter depends on your solar-panel system's size and location. String inverters are affordable, efficient, and common for residential solar systems. However, microinverters converting power on each individual panel may be better if some of your panels get shade for part of the day.

Are off-grid solar inverters worth it?

Off-grid inverters help charge and discharge solar batteries to keep your home running. DIY systems aren’t worth it for the average homeowner, but for those with strong electrical skills, DIY solar panels can be worth the investment. Solar inverters differ in several ways, including efficiency, cost, and warranty coverage.

How big should a solar inverter be?

If you have a 7 kW solar panel system, your inverter size should also be at least 7 kW (7,000 watts). Getting a solar inverter with a much larger wattage than your solar array can cause efficiency and performance issues.

Should I get a solar inverter with a bigger wattage?

Getting a solar inverter with a much larger wattage than your solar array can cause efficiency and performance issues. An installer will properly size your inverter with your solar panel system based on the size of your solar array and the amount of sunlight your home receives throughout the day.

How to choose a solar inverter?

The higher the energy loss, the lower the efficiency rating. Look for solar inverters with high efficiency ratings between 96% and 99%. Depending on the type, solar inverters will match either your system size or your panel size. The string inverters’ maximum output capacity should match your system size.
