A challenging project. There was a misunderstanding with the client. During the project execution, the technical specifications changed. It was difficult to get corrections. Had to guess what he wanted.
Overall, a pretty good design turned out. https://freelancehunt.com/showcase/work/bigbord-solnechnyie-paneli/1947863.html
But the logo is better read if made in two colors.
And using only a phone as a communication channel requires an action from the client that he may be ready for.
Therefore, the website and social networks can still be useful – they will attract those who are not yet "warmed up" for a call.
