Solar carbon credits from metered generation
See how a renewable solar energy project earns credits: a clear baseline, metered generation, and a design that shows carbon revenue made the difference.
Grid-connected solar, measured against a clear baseline
What it is
A solar project generates electricity from photovoltaic panels, on the grid or off it. Every unit displaces power from a fossil-fuel-heavy grid or from diesel and kerosene generators.
Why this method
Reductions come from metered net generation and a grid emission factor, so a verifier can check every credit against meter readings at the interconnection point.
How a solar credit is calculated and checked
Methodology
Baseline: the grid emission factor for the region or, off the grid, the fuel the system replaces. The gap between that baseline and what the project emits is what gets credited. Bar proportions are illustrative.
On the grid, the baseline is the grid emission factor, built up or blended from operating and build margins. Off the grid, it is the fuel the system replaces.
Metered net generation in kilowatt-hours, multiplied by the baseline emission factor, less project emissions such as backup diesel.
We show the project would not have gone ahead without carbon revenue, using a barrier analysis, a common-practice test, or an investment analysis.
MRV approach
1. Meter readings
Continuous or periodic readings at the interconnection point record the net electricity the plant sends out.
2. Commissioning records
We check commissioning and capacity records against your registered design, so verifiers see the same plant on paper and on site.
3. Project emissions
We net out emissions from the project itself, such as backup diesel, before any reduction is counted.
4. Additionality evidence
Verifiers review the additionality assessment alongside the meter data, to confirm the project needed carbon revenue to go ahead.
Straight answers on solar credits
Start with the questions we hear most before a solar project begins, then bring us your details.
Yes. Solar energy is renewable, and a solar project can earn credits when it shows reductions against an approved baseline and passes the additionality test. The standard, the methodology, and the plant's start date also matter, and we check each during screening.
We multiply the plant's metered net generation by the baseline emission factor, then subtract project emissions such as backup diesel. The result, in tonnes of CO2e, is the reduction a verifier can confirm and the registry can issue as credits.
Additionality asks whether the project would have gone ahead without carbon revenue. A solar developer usually shows it through a barrier analysis, a common-practice test, or an investment analysis, depending on the methodology.
It can. Off the grid, the baseline is the fuel the system replaces, such as diesel or kerosene, rather than the grid emission factor. The standard and methodology you choose decide what data you need to collect.
Verifiers look at meter readings at the interconnection point, commissioning and capacity records, and the additionality assessment. We help you collect and organize them each monitoring period, so verification runs without gaps.
