Your ASTM E2848 Test, Fully Handled
Send us your data. We run the capacity test against your PPA or EPC contract requirements, generate the report — and you get full visibility into every step through the Heliotest platform.
What You Receive
A complete, audit-ready test package
Everything you need to demonstrate compliance and close out your project — with no black boxes.
- Auto-generated PDF report
Structured, ASTM-compliant, ready to share with investors or offtakers.
- Full data export
Raw filtered dataset, regression outputs, and test statistics — yours to keep.
- Live project access
Your project stays in the platform. Review results, explore the analysis, run what-ifs.
Four Steps from Data to Signed-Off Report
We handle the methodology. You handle the project. No spreadsheet wrangling, no back-and-forth on data formats.
Share Your Data
Send us your measured timeseries data (inverter power, POA irradiance, temperature, wind speed) and your PVsyst hourly simulation output.
We Configure the Test
We set up the test parameters — reporting conditions, regression window, filtering criteria — in alignment with your contractual requirements.
Test Execution & QA
The test runs on the Heliotest platform. We review the results, check data quality flags, and validate the output before delivering anything.
Delivery & Handover
You receive your PDF report, data export, and full access to the live project in the platform — with complete traceability of every calculation.
Not Another Black-Box Consultant Report
Traditional consulting firms deliver a PDF. You have no idea what was filtered, what was assumed, or whether the method holds up to scrutiny. We show you everything.

Built for C&I Solar Teams Who Need Results
The managed service is the right fit if any of these sound familiar.
Proving system performance to your offtaker
You have a PPA with a capacity guarantee clause and need a defensible, compliant test result to close out your project — without tying up your engineering team.
Delivering on contractual performance obligations
You've commissioned the system and need the capacity test as part of project handover. You want a repeatable process you can trust across a growing pipeline of sites.
Independently verifying system output
You're acquiring or monitoring assets and need a third-party capacity assessment with full methodological transparency — not a number on a slide deck.
