We have the full wack 4kw solar panels. My thinking was, it would be best to use the washer, dryer and dishwasher during the day when it’s bright (free electricity will always be cheaper than off peak!). But someone told me that probably wouldn’t work and I should set timers so the machines work at night when it’s cheap (not the dryer - could be a fire risk). How do I calculate when it would be most energy efficient to use the machines?
Also, we work from home so in the winter heating is needed all the time. We have gas central heating and what we do is have that on in the morning and evening, but during the day use electric fan heaters (hopefully being solar powered) in our two offices. Is that the most efficient and ecological way? (I don’t mind doing the calculations, but I don’t know what they should be!).
