Solar inverters are the most common breakdown point.

Some questions to consider going completely “off the grid” beyond the electric usage return on investment...

Does your solar company offer 24 hr, 365 day repair support? Does that house call come within 1-2 hrs ? Does a governmental agency monitor your solar companies breakdown to restoring power (fix) support time?

Does your solar company include a maintenance program to come out to your house and check your equipment for as long as you are using the solar?

If your solar equipment fails or has an issue, does it automatically sent a message to repairman to come out and make a house visit without you calling?

If you are “off the grid” and have no continuous financial connection with the company that sold you the equipment or any other solar company. Is that maintenance support included with the initial cost of your equipment or is it an additional monthly service/insurance fee?
