For those who have been curious about this thread or who may in the future be curious about this thread I believe it is safe to say the working and re-working that took place as this thread formed has reached a logical and successful conclusion. The Emoncms graphs now being produced successfully display my home energy usage overlaid by my solar production in such a way that the two are meshed and an accurate overall energy snapshot of our household is portrayed by the graph.
In this graph you’re seeing energy usage starting at around 0800am, the various initial spikes are the coffee machine going on and my desktop computer’s fan running and shutting off. The light blue is the sun just rising over the trees across the street from my house and the solar panels covered partially in snow producing a wee bit of energy. Around 1115am our energy usage was below the solar electricity generated and the graph displays pure yellow. You can then see the sun came out and although the panels are partially covered in snow the diodes were firing and the panels were producing electricity but not enough to offset the huge 7k+ spikes from our clothes dryer running. The nice yellow area around 13:30 is when we left the house to go to the park and our baseload dropped while the solar modules sucked up the sun in our absence.
