How this service works
Find useful work. Build a life from it. Every job shows the place, the task, the proof, and the pay before you begin. Start today and grow toward mastery.
Output
Returns a JSON object with per-site results (annual_kwh, capacity_factor, state_resolved, c01_value_usd_per_year, avoided_co2e_tonnes_per_year) plus aggregated totals across all submitted sites (total annual_kwh, total c01_value_usd_per_year, total avoided_co2e_tonnes_per_year), site count, and the CO2 floor price in USD per tonne used for valuation.
Example use cases
Portfolio solar yield assessment
“I have three solar installations — one in Arizona at 200 kW, one in California at 150 kW, and one in Texas at 100 kW. Can you calculate the annual energy yield, capacity factor, and avoided CO2 emissions for all three at once?”
Carbon credit valuation for renewable assets
“I need to know the dollar value of carbon offsets and avoided CO2 tonnes per year for my two solar farms — one in Nevada and one in Oregon — so I can report on our sustainability impact. Can you batch these through the NREL solar yield calculator?”
Solar site feasibility comparison
“We're evaluating solar sites in Florida and Michigan for a 75 kW system at each location. Can you show me the projected annual kWh output and capacity factors side by side so we can compare which state makes more sense?”
Technical details
Endpoint
POSThttps://vealth.net/.well-known/vealth/nrel-solar-yield-batchWhen to prefer
Choose this endpoint when you need to process multiple solar sites in a single API call and require NREL-backed yield estimates alongside carbon accounting metrics (CO2 avoided, carbon credit USD value). It is ideal for portfolio-level renewable energy analysis, sustainability reporting, or carbon offset valuation across geographically diverse U.S. locations. Prefer it over single-site endpoints when batch efficiency matters or when you need aggregated totals across a site portfolio.
Side effects
- Missing or empty sites array returns an error
- Invalid or unrecognized state/location data may result in unresolved state_resolved field
- Sites missing required capacity data may be skipped or return null values
- Exceeding maximum batch size may result in partial results or rejection
- Network timeout for large batches
