The short version

  • Each has a real cost: Kahua no standard pricing tiers published; all pricing is custom and quote-based; 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.
  • They diverge on capability: Kahua covers Project management, Sitemark covers Construction progress tracking.
  • 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.

Kahua

  • No standard pricing tiers published; all pricing is custom and quote-based
  • Pricing varies by organization type, program or construction scale, selected package, and deployment environment
  • Implementation costs for data migration, integrations, training, and configuration scoped separately and included in quote

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  • Pricing is quoted on site count and unpublished variables, which penalises owners of many small distributed assets relative to one operator of a single large plant with the same total capacity.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.

Answered from the vendors’ own pages

Kahua: How much does Kahua cost?

Kahua does not publish standard pricing. Costs vary by organization type (Owners/Program Managers, General Contractors, Specialty Contractors), program scale, selected package, deployment environment, and implementation requirements. Customers must request pricing quotes.

Source
Sitemark: Is Sitemark priced per megawatt?

No. Sitemark states pricing is based on number of sites and other variables. Ask explicitly how a portfolio of small sites is treated, because per-site pricing is unkind to distributed assets.

Kahua: What package options does Kahua offer?

Kahua offers three main package categories: Owners and Program Managers, General Contractors, and Specialty Contractors. Additional specialty apps and suites including capital planning, analytics, asset management, and safety can extend the base solution.

Source
Sitemark: Do we have to use Sitemark drone pilots?

No. It accepts data from third-party drone operators, which lets you keep an existing flight contractor.

Kahua: Are implementation and integration costs included in Kahua pricing?

Implementation details including data migration, integrations, training, and configuration are scoped based on requirements and clearly identified in the custom quote provided.

Source
Sitemark: Does it cover anything other than solar?

No. It is built specifically around solar plant structures and defect types.

Sitemark: Can we export our data?

Yes, orthomosaics, defect lists and reports export. Confirm the format and whether historical inspections remain accessible after a subscription lapses.

Sitemark: Where is the company based?

Leuven, Belgium, with customers across Europe, the Middle East, Asia and the Americas.
