Every number
carries its
grade.
Built for the sustainability, energy and finance leads running 5 to 100 solar sites — manufacturers, logistics and cold-storage operators, retail chains, agri-businesses, schools, municipalities and commercial landlords — preparing figures for CSRD/ESRS review.

Provenance
Provenance is the product, not a feature.
Every site number on SolarImpact — energy produced, avoided emissions, cost saved — carries one of four grades: Measured, Calculated, Estimated or Verified. The grade travels with the number wherever it goes.
When a grid factor version changes, last month’s figures become restatable. The export cites which factor version produced each number, so nothing is silently rewritten.
Evidence Pack
grade kept on every row
Every monthly import lands with a grade already attached.
Meter readings, invoices and grid factors come in on the same schedule your reviewer expects — a new-imports-due email each month. Each row is graded the moment it arrives, before anyone touches it.
- Meter data graded Measured on arrival
- Missing rows marked Estimated, never silently filled in
- One organisation, unlimited imports, up to five sites

See exactly how much of your number is measured.
A coverage statement sits above every report: what share of this figure is Measured or Verified, and what share is Calculated or Estimated. Nothing is hidden inside an average.
- Coverage shown before the total, not after
- Estimated rows cite the assumption they used
- Calculated rows cite the formula and inputs
One Evidence Pack per site, ready before the reviewer asks.
Across up to five sites in one organisation, every number keeps its grade and its cited factor version in the Evidence Pack export — the same figures whether you’re reading the screen or the file.
- Grade shown on screen, in the export and in the database record
- Factor version cited beside every calculated number
- Unlimited imports included on the Site plan

Who it’s for
Built for the teams who own the sites.
Manufacturers
Solar across production sites, graded the same way at every plant.
Logistics & cold storage
Round-the-clock sites where every reading needs its source on record.
Retail chains
Dozens of small roofs reported the same way, site by site.
Agri-businesses
Seasonal generation with the assumptions behind every estimate shown.
Schools & municipalities
Public reporting that shows what was measured and what wasn’t.
Commercial landlords
Tenant-facing numbers with the grade attached, not just a total.
The grade is not a tooltip.
It’s a column, not a caption. The same grade sits beside the number on the screen, inside the Evidence Pack export, and on the database record behind it — so a reviewer can trace any figure back to how it was actually obtained.
- On the screen, next to every number
- In the export, as its own column
- In the database, on the record itself

The number that survives a reviewer is the one that says how it was found.
This is the data you uploaded ten minutes ago, read back with a grade and a cited factor beside each figure, above a coverage statement that admits what was estimated.
