July 24, 20215 yr Does anyone have actual energy production of a PV system over the course of a day preferably on a sunny day. Thanks.

July 25, 20215 yr Got my best production the other day when it was so extremely cold. Got 29.3 kw from my 14 x 380 watt JA solar mono panels

July 30, 20214 yr Interesting to see how other systems are doing. How do you guys manage to not use any power from the grid?

In my case I do use grid as well but it is not shown on the graph, the graph only shows my essential loads that are mostly powered by solar and battery and they are things like the WiFi, cctv, electric fence, lights, fridge, computers and TV’s. My non-essentials are grid-feed only and those are the dishwasher, oven, geyser, microwave, and some heavy loaded plugs in the kitchen, these are powered before the inverter and is not seen by the inverter.

Makes sense. Thanks

You are getting a lot of answers here, and they are all different and not definite. There is no one answer. It depends on the number of panels you have, the type of panels, what your inverter can process, the weather, the orientation of your panels, the time of year etc etc.
