Measure vegetation shading on Amherst landfill solar, Amherst, MA.

One branch across one string costs far more than its share, because a shaded cell drags the whole string down. Photograph Amherst landfill solar from a fixed public-ground spot at three sun positions on one clear day, mark what is shaded and by what plant, and set that beside the same day's production profile. a closed landfill cap carrying a town-owned array, which is surface ground only. The result names the specific stems that cost output, so the pruning packet that follows knows exactly what to cut and, just as importantly, what to leave.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

three dated sun-position photos from one fixed spot + shaded-area sketch naming the plants + same-day production profile

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• laptop or tablet with a spreadsheet
• the array's public production dashboard address, or the owner's meter export
• a named public irradiance source such as NREL NSRDB or the nearest public weather station
• the array's published nameplate DC rating and commissioning date
• camera and a GPS phone for the single public-ground photo

Steps

1. 1. Record the array's identity: host, address, nameplate DC rating in kW, module count if published, commissioning date, tilt and orientation if published, and the production dashboard address. If no dashboard and no owner meter data exist, stop and publish that as the finding.
2. 2. Download the period's measured energy in kilowatt hours at the finest interval the source offers, and record the interval, the time zone and the download date.
3. 3. Pull irradiance for the same period and the same location from a named public source, and state whether it is plane-of-array or global horizontal. Never substitute a design assumption for a measurement.
4. 4. Compute expected energy from the nameplate rating and the irradiance, then the performance ratio as measured over expected, leaving every input visible in the sheet.
5. 5. Name the losses the public record supports: shading, soiling, inverter downtime hours, curtailment. Publish anything you cannot name as unexplained rather than assigning it to a cause.
6. 6. Publish the sheet in full with its sources, take one photo of the array from public ground, and anchor the published file's content hash.

What counts as done

• Three photos from one fixed spot at morning, midday and afternoon on the same clear day, with times and GPS
• A sketch or marked photo showing which modules are shaded and which plant casts each shadow, named to species where you can
• The same day's production profile from the dashboard or the owner's meter, with its source
• The specific stems recommended for pruning and the ones recommended to keep, with the reason for each

Proof is measured against these, not judged by taste.
