I would never thought solar was that viable until I really looked into it and even on over cast days it provides enough energy for the home. Definitely would look at this for the next house if I was you as there is only 2 of you and you would not need a massive system either. When we move into our next home I will go much bigger because hopefully I can then generate passive income from supplying to the grid which I cannot do here. I know you like income streams and this is ideal.
