I like that they are able to give us an estimate using our data from Google maps for where we live in order to determine how much solar would benefit my home! What is not so great about this product? It's very easy to use once you get used to it but there could be more options when creating accounts or even just logging into your account online if needed. The benefits received by having installed solar panels at work helped me realize what type of impact working with renewable energies can have as well as help others understand why these types of products should exist today.
