How we rank the best agencies
The ranking blends two things: how well each company suits solar panel installers and how they convert, and a fixed seeded weighting that keeps the table honest rather than always favouring the same name. We look hardest at the pricing model, whether leads are exclusive, and the channel mix. Every claim reflects the company's own stated approach, and we don't invent results.
