I've only had mine for about a year, but realize now that it's totally different and you get very differing information when you're actually ready to put money down and start running real numbers. You see everything in a totally different light.PS. I have a large domestic solar pv installation in one of the sunniest areas in the country, and many years of experience in running a house off solar. Have been exporting to the grid for six years.
How are you exporting to the grid? Are you getting paid for it, or do you just have an old meter that runs backwards? I'm exporting to the grid, but have a newer electronic meter, so don't get any credit for it
