The short version

  • Each has a real cost: Kojo benefits depend on distributors providing electronic catalogues and pricing, and a contractor whose main supplier will not participate is left keying quotes by hand.; 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: Kojo covers Field material requests, Sitemark covers Construction progress tracking.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Kojo

  • An electrical or mechanical contractor where materials are close to half of job cost and buying happens dailynot Sitemark
  • A trade contractor that cannot see committed material cost against a job until the invoice arrivesnot Sitemark
  • A contractor consolidating purchasing across branches to negotiate better distributor pricingnot Sitemark
  • A subcontractor tracking warehouse stock and job transfers that currently live in a spreadsheetnot Sitemark

Sitemark

  • An EPC contractor on a multi-hundred-megawatt ground-mount plant that must report weekly installed counts to a lender and cannot do it by walking the rowsnot Kojo
  • An asset owner accepting a plant at provisional acceptance who needs documented evidence that what was built matches the issued design before signingnot Kojo
  • An operations team running annual thermographic inspection across a portfolio, wanting defects mapped to module positions so a technician goes straight to the faultnot Kojo
  • A developer comparing defect and underperformance rates across contractors and module suppliers to inform the next procurement roundnot Kojo

Where each one falls short

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

Kojo

  • Benefits depend on distributors providing electronic catalogues and pricing, and a contractor whose main supplier will not participate is left keying quotes by hand.
  • It serves speciality trade contractors; general contractors procure subcontracts rather than materials and get almost nothing from it.
  • Enterprise resource planning integration quality varies by system and version, so confirm the depth for your exact configuration rather than accepting the logo on the website.
  • Field adoption is the whole game, and foremen who lose signal in a plant room or basement revert to phoning the office within days unless offline capture genuinely works.
  • It changes purchasing process as well as software, so contractors whose buying authority is informal have to formalise who can commit money before the system produces clean data.

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

Kojo: Is this for general contractors?

No. It is built for speciality trade contractors buying materials. General contractors procure subcontracts and would get little from it.

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.

Kojo: What if our suppliers will not connect?

You lose most of the quoting benefit and keep only the internal workflow. Check distributor participation before purchase, because it determines the return.

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.

Kojo: Does it work without signal on site?

Field requests are designed for site use, and offline behaviour should be tested with your own crews in your worst locations, because that is where adoption is won or lost.

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.
