I haven't yet purchased from them.
I am exploring the possibility of doing solar this year and have been in communication with them.
Their staff is helpful and responsive. They appear to know more than just the basics and can help you make a selection of what kit to get. Their prices appear to be decent. (though if you are well researched, Renvu can have better prices, but they are aimed at professionals).
If I go through with it I will try and remember to report back. But, I suspect a few insulation upgrades make more sense than solar at this junction (more return for less money).
Sorry I cannot provide greater input.
