How we chose these
Same scoring engine as the main Baltimore solar ranking, with an additional filter step: we look for Commercial signals in each provider's business categories, service tags, and recent review text.
When the Commercial filter would surface fewer than five providers, we fall back to showing top-rated solar pros generally - they are far more likely to handle commercial work than an unrated provider would be.
