Think its a lot more complicated than that even when this country is generating power we burn gas and coal to export to Europe and vis versa .Its likely best to self consume what you are producing .In the summer. I do not need to use my gas boiler so no local pollution. Would you criticise someone who went completely Off grid and relied on Pv or wind for all his power.0

Petriix said:I think it's also mostly a myth (or wishful thinking) that self-consuming solar is 'greener' than burning gas. If you consider how the last bit of grid demand is met, burning gas at home is almost always greener than causing more demand on the electric grid. Exporting your solar usually does more good than not burning the equivalent amount of gas. It's optimal to minimise your demand and maximise your exports in most cases.Northern Lincolnshire. 7.8 kWp system, (4.2 kw west facing panels , 3.6 kw east facing), Solis inverters, Solar IBoost water heater, Mitsubishi SRK35ZS-S and SRK20ZS-S Wall Mounted Inverter Heat Pumps, ex Nissan Leaf owner)0

Today, with export prices at 15p and off-peak imports at 7.5p it's only in unusual circumstances that any diversion would make sense. The best thing is to minimise usage and maximise exports.If you are on a very cheap overnight tariff like IOG (7.5p) and are paid export at 15p/kWh then, yes, ditch the diverter.0
