I’ve been a bit busy to monitor my usage regularly, of late. Feeling out of touch, I made a point of checking my solar generation after recent rainy weeks.
It seemed a little low. Usually I hit 5kW around the middle of the day, but was peaking out at 4.6kW. I was contacted by someone who lives nearby with a corresponding fall in numbers.
The only theory we have to go off is lower angle of the sun. Additionally, because there were two weeks of Autumn where we almost never saw direct sunlight, we didn’t see the slow decline over time.
Its like seeing someone’s kids only occasionally – can’t believe how much they’ve grown! Their parents see it every day.
Having not checked anything for a while, I headed over to the SolarEdge Monitoring Portal to compare their results to Reposit. Having a second source for comparison is very helpful to sort out any discrepancies.
Well, there certainly have been some changes! And all of them look like winners.
The first noticeable change was the new Monthly profile for Power and Energy.
There was a period where the “self-consumption” figure wasn’t being reported through some conflict with the Reposit interface. That’s back, which is great.
Added to this is the “From Battery” stat which is quite cool. It features both in the Consumption summary figure, and the bar graph. This is only recent, so I look forward to that percentage figure “from batteries” smoothing out with a larger data sample.
If you mouse-over any of those bar graphs it gives you the details, in kWh, for the days that have been completed. Again – very vool.
I also hadn’t given much thought to the year-on-year comparison before I had enough data. Now its very handy to answer questions I and my near-neighbour have about long-term performance.
For reference, the figures are in the table below for the three months with suitable data.
|Month||MWh 2016||MWh 2017|
* As of April 24.
What I find really interesting is the March figure; despite having an extra 1.5kW of panels this March compared to 2016, the weather meant I didn’t generate quite as much.
Moving forward, I’m sure subsequent years and months will prove to be most interesting. I love me some data!
Live Baby Live!
They’ve also updated the Overview panel to have near-real-time feeds of consumption. I did a quick screen cap of this and stuck it on my YouTube Channel. I like.
All in all, a great round of SolarEdge Updates as we move toward the cooler months.
