   @gareth @Disputatore @Sarahw @vfrmedia @kibcol1049 after the mileage charge still just 5 or 6p per mile but look at the cost of home batteries. You can charge them at the 7p rate too. Mine have reduced my electricity bill so the car costing a negative rate per mile

     My relatives have solar + batteries and it seems the batteries are more useful for resillience rather than immediate payback - a couple of months ago they lost the grid supply for a whole hour (at least during daylight in good weather) and the entire house power demand was picked up by the solar + batteries without even making much of a dent in the battery charge level (rather like a giant UPS)

     @Disputatore @gareth @Sarahw @vfrmedia @kibcol1049 batteries are complicated . I can only use the UK situation. Solar on its own will pay back quickly if you get a good rate for export and, as in your country, loads of sun. Batteries are expensive and add to the years of payback. They are more a reaction to ever increasing electricity price rises rather than quick returns

     @John_Loader @gareth @Sarahw @vfrmedia @kibcol1049 I was told the UK has a government scheme where if you buy solar panels and batteries together you don't pay VAT, or something. That's a great offer. But there is no incentive scheme in Portugal to buy batteries. I bought solar panels with a government incentive plan. With the savings and the first year of selling excess production, I was able to pay for the panels in less than 18 months. But I can't find a business case for batteries.
