How this service works
Long-term solar irradiance for any location on Earth (NASA POWER, 2001-2025) by month, with temperature, wind and an estimated PV yield, specific yield and capacity factor for a system size. Use to screen solar sites.
Output
Returns a breakdown by month of solar irradiance (GHI/DNI/DHI), ambient temperature, and wind speed for the given coordinates derived from NASA POWER 2001–2025 climatology, plus computed estimates of total annual PV energy yield (kWh), specific yield (kWh/kWp), and capacity factor for the specified system size and performance ratio.
Example use cases
Rooftop solar feasibility check
“I'm considering installing a 10 kWp solar system on my warehouse in Phoenix — latitude 33.45, longitude -112.07. Can you pull the monthly solar irradiance and tell me the estimated annual energy yield and capacity factor?”
Solar farm site comparison
“I need to screen two potential solar farm sites: one at lat 35.2, lon -101.8 and another at lat 32.7, lon -97.3. Can you get the long-term solar resource data and specific yield for a 500 kWp system at each location?”
International solar project screening
“What's the solar potential in Nairobi, Kenya — around latitude -1.29, longitude 36.82? I'm planning a 25 kWp off-grid system and need monthly irradiance plus an estimated PV yield with a performance ratio of 0.75.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/energy/solar-resource?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need long-term climatological solar resource data (20+ year averages) for site screening or feasibility estimation at any global coordinate, especially when you want an integrated PV yield calculation rather than raw irradiance alone. Prefer this over real-time weather APIs when you need stable multi-year averages for investment or planning decisions rather than short-term forecasts.
Side effects
- Missing required lat/lon parameters returns a 400 error
- Coordinates outside valid Earth bounds (-90 to 90 lat, -180 to 180 lon) may return an error or no data
- NASA POWER upstream data unavailability may cause 503 or timeout
- Invalid performance_ratio outside 0.3–1.0 range may return a validation error
- Payment failure (x402) returns 402 Payment Required before data is delivered
