Solar PV...Still worth it?

Unfortunately not that simple , it will depend on the tariff you are on. Me for example an on octopus Go and pay 5p off peak 15p peak . I charge the car off peak atm probably about 10kwh per night if I were to charge with solar I would only save 50p not £1.50.I would say £5k is more realistic these days for a 4kw and self consumption around 30% peak if no battery and using a TOU tariff. 

Could still make sense I just depends how much electricity that you can’t move off peak you will use between say March to September. 

One the plus side for pv prices of energy seem to be only going one way.

I don't think it makes much sense to calculate ROI based on legacy tariffs which are way below the current market rate. The latest Go pricing is less favourable.

I was basing it on what I would have saved based on what I am on now as I have no Crystal ball but the standard rate will also change in April and for me those are my prices until May and ATM Go will still be a lot better than Cap . On the plus side though PV ROI will be better.

All I'm saying you shouldn't just look at solar ROI you should consider the tariff as well, for example i could probably switch to a 50p per KWh tariff now which would may solar ROI much better but I would be paying £10k a year for my electric ! 

So the question is solar worth it always depends on multiple factors and is individual.
