Hi Richard,haveing lived in Scotland,Peterhead for a short time myself,may I say hello to a lovely side of the country.....
Having to cope with a rather heavy need of energy is always a challenging thing...adding usage is even more,while the goal would be reducing energy needs.Imho you have got three options: You try to add panels and storage,where ever you can,maybe you could build a support construction around or on sime sides of the house to have some bifacial's near ground,for ex. east/south or east/west, to cover longer hours of harvest.The second option would be a hybrid system with any other energy producer like wind or water.....The third option and maybe the most interesting and economic way,would be to get together with some neigbours and have a storage system installed which serves all.In this case you could concentrate on producing....and harvesting🤑Best regards Frank
