As with any industry, the solar space is broad and multifaceted, with a spectrum of professionals working across all kinds of geographic regions. Your biggest question right now is "who will see the most value in my website?"
Then, you proceed as others have suggested: determining how to best reach these folks.
To gain early traction, it helps to identify that ideal customer, since that should be your easiest "sale."
