Power Move and Solar Panels - do they help or hinder me hitting my target?

Very interesting comments I have solar no batteries. I tried during power move to turn most electric equipment off. Sat in dark watching battery driven tablet with gas fire on. I got 37p. Not worth the sacrifice.  Mantra in this household Sun out washing in. I always look for sunny days to use washing machine and tumble dryer 

Hi @SRF, yep, Power Move Plus is difficult when you have solar panels, because as you say most heavy usage is already shifted from peak hours to sunshine hours.  And of course there are only a handful of Power Move Plus events anyway.  
 

Now, Power Move itself (not Power Move Plus), that’s a whole different kettle of fish, as even with solar panels there’ll still be a contribution, especially during the winter, from the grid for heavy items even when the sun is shining.  Unless one has a massive array, or has a charged storage battery ready to help out, I’m guessing most panels in a UK winter just can’t cover surges demanded by ovens, washing machines, electric kettles, tumble driers etc. especially when additional “always on” stuff like ‘fridges and freezers etc are constantly cutting in and out as well.  Actually, even in summer sunshine my own panels can’t completely cover most heavy items: maybe microwave, our modern hoover, anything up to around 2 kW, but definitely not in winter!  Some Dec/Jan winter days I’m lucky if we generate an average of 100 Wh for the six or seven hours of daylight! ! So, Power Move (the OVO monthly one) is still definitely on I find, even with solar panels, as there is still that potential to make the 4 - 7 peak hour slot smaller than the average three hour slot in the rest of the weekday. 
 

So, even though you are efficiently moving heavy tasks to daylight sunny hours, maybe you could still have a look at your monthly average weekday consumption, your average weekday peak hours consumption, and also check your weekend consumption in case you can move some tasks to a weekday non-peak-hour slot, and see whether you can perhaps juggle tasks so that your AVERAGE (odd anomalies now and again during the month don’t necessarily matter) weekday peak hours electricity consumption is around 11-12% of your AVERAGE weekday electricity consumption?

But, most definitely, do not aim to sit in the dark or cold!  Brrrrrrr, no thank you: if we are amongst those in the fortunate position nowadays of being able to afford energy to keep ourselves fed and watered in reasonable security and warmth, then let’s please do that! But if we can shift usage, especially heavy usage, around a bit to help overall grid usage patterns, and earn into the bargain the equivalent of 50 kWh or so of electricity per month, then it’s definitely worth a serious look I reckon!
