To all my friends with solar systems. Don’t take them for granted. My inverter went out. We have high usage and just added more panels. The bill was high one month, but I just thought that it was because the new panels weren’t on line. But it was the inverter and the next month the bill was over $700. Monitor your system. There may be a website from your solar company or you can view net usage on your utility’s web site. Don’t wait a month to find out you system went down.
