I monitored the forecast generation and compared it with the actual generation of my 3 kWp array for about a month. Overall it slightly underestimated my generation but on a daily basis it could be extremely inaccurate with generation often half or twice the forecast. Today has been an extreme example. 9.8 kWh forecast, 2.3 kWh generated. Quoting half hourly forecasts with a precision of 1 Wh (3 decimal places kWh) is ridiculous.
Just been trying this and it is not bad but underestimates my system output. I wonder if it is to do with the PGIS database which tends to be pessimistic. Big annoyance for me is the seriph typeface. Please use sans-seriph, it is MUCH MORE READABLE.
The app handles up to 3 (differently facing) arrays of panels. Values show good agreement with my observations and so I highly recommend this app. Since one typically wants to minimise home generated exports of electricity it does help one to plan tomorrows energy intensive activities (dish washer, washing machine, tumble dryer, electric oven/air fryer).
Added a 3.5 kw west array to my old 2.5 kw south array plus a 10kw libbi, zappi and eddi. This is exactly what I was looking for. You should be talking to Myenergi to integrate this with their app. Great work!
I look forward to when more than one panel orientation can be catered for. Currently I am getting passable guidance with approximations in my setup.
Great app. Keep up the good week. Looking forward to seeing how this app grows.
