[QUOTE="binky, post: 502473, member: 490"] the numbers tend to work out at about 12 year payback, based on single charge/ discharge per day. You can enhance this with grid-trading, but as that pays about 5p per kWh it seems daft to spend so uch to gain so little. If, you can charge / discharge battery several times a day, it does make a big difference to pay back times, but this is an unlikely scenario for most people. Persoanally I reckon you are better off with an electric vehicle that is 'at home' a lot (ie you are retired). Some of the solar inverters have EV charging built in, you then want a unit that can be programmed to charge up car only when surplus leccy is being generated by a set of solar panels. Evn ths doesn't give great pay back, but if you hate paying money to utility companies, it may suite you? [/QUOTE]
