I receive monthly energy production reports from every one of our customers that has an Enphase microinverter based solar energy system. It’s great to see at a glance if systems are performing as expected, especially relative to the prior month and relative to other systems of similar size.
It’s already April, and the numbers for March are in. There is a link below to a typical monthly energy report that I get via email. This is a summary report that has a lot more data available behind it on the Enphase Enlighten portal online.
It shows what I’m seeing across the board, and what is expected for this time of year. Solar electric production was up 10-20% in March over February in Southwest Florida.
I can’t say enough about the importance of monitoring solar energy output, identifying shading and soiling issues, along with ensuring equipment continues to meet specifications. Enphase makes this easy by providing rich data sets and graphic representation of each microinverter’s output. Below is a graph for the same system in the report above for March, 2013.
You can essentially “tell the weather” with a solar energy monitoring system. March 12 was clearly the cloudiest day. You can dig even deeper into the daily power production over time. Check out the difference between March 12 and March 27, the best day of the month for energy production.
