How this ranking works. This list is generated algorithmically from the SolarXList directory and refreshed daily: ① only companies with a stored verification record (for example, a website confirmed reachable by our crawler) are eligible; ② eligible companies are ordered by membership level, verification and listing completeness (contact details, description, location data).
