The short version

  • Only Buildxact has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildxact 15% discount applied only to annual billing; Sitemark it only does solar, so a mixed renewables portfolio still needs a second platform for wind, storage and substations, and the consolidation argument for buying it collapses.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Buildxact

  • 15% discount applied only to annual billing
  • Advanced AI add-ons require additional per-month fees

Sitemark

  • It only does solar, so a mixed renewables portfolio still needs a second platform for wind, storage and substations, and the consolidation argument for buying it collapses.
  • Pricing is quoted on site count and unpublished variables, which penalises owners of many small distributed assets relative to one operator of a single large plant with the same total capacity.
  • You still need someone to fly the site, and Sitemark does not remove the drone operator cost, permits or airspace constraints; it monetises the data after the flight.
  • Automated progress counting depends on a clean, current design layout, and on projects where the layout changes weekly the comparison generates false deviations that erode trust in the numbers.
  • Thermographic defect detection needs the plant producing at sufficient irradiance, so inspection windows in northern latitudes are narrow and a missed window pushes findings into the next season.
