I haven't paid an electricity bill in over 10 years! ... Not since I went fully offgrid Solar! It is a real joy, it feels so good not to be using coal or nuclear generated energy! It has certainly made me more vigilant with my power usage and has not been difficult at all. I easily charge electric bikes/skateboard and can run washing machine, computers, synthesisers etc. We do use a gas fridge but there are now some excellent 12 Volt fridges becoming available at at cheaper prices to.
If you would like to generate your own power do not hesitate to ask any questions you would like answered. I would be happy to share my experience.
do you live in Canada? or is it just that the Battery is from Canada? I'm surprised you get enough Sun anywhere in Canada in Winter
