[QUOTE="johnb2713, post: 553339, member: 35153"] I personally would turn it around the other way, look at your daily consumption figures and get enough battery storage to cover that plus a backup margin. Look at your peak consumption and use that to size the inverter. That creates a battery system that can run the house all day at off peak pricing. Now with the budget remaining get as much solar that the budget allows. There are times with companys like Octopus where they have 'saving sessions'. If you export to the grid during these times you get paid up to £4 per kWh (this years price), a considerable amount of money can be made if you have the capacity to store energy and discharge it into the grid at the appropriate time. On my system I bought energy at 7.5p kWh and sold between £2.25 and £4 giving me an income in December of £135. These grid balancing sessions are definitely on the increase and worth taking into consideration. During the good weather I export all what my solar generates with my house running on battery, again buying energy at 7.5p but selling my solar at 15p, not a lot but it does add up. [/QUOTE]
