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