How this service works
Solar irradiance analysis and 7-day forecast for any location. Returns GHI (global horizontal irradiance), DNI (direct normal), DHI (diffuse), peak sun hours, cloud cover, sunrise/sunset, and panel yield estimate for a 1 kW system. Useful for rooftop solar feasibility, agricultural planning, EV charging optimization, and energy market analysis. Free upstream: Open-Meteo (no API key, no rate limits). Undercuts stableenrich.dev/api/google-maps/solar by 31%.
Output
Returns solar intelligence data such as solar irradiance, solar activity metrics, space weather indices, or photovoltaic-relevant environmental readings, depending on the properties parameter provided.
Example use cases
Optimize renewable energy grid dispatch
“Pull the latest solar irradiance readings and space weather indices for our regional solar farms so we can forecast power generation and balance the grid efficiently over the next few hours.”
Real-time photovoltaic performance monitoring
“Fetch current solar activity metrics and photovoltaic-relevant environmental data for our rooftop panels — we need to track actual output potential against weather conditions right now.”
Agricultural crop scheduling by sun exposure
“Get the solar irradiance levels and sun exposure forecast for our fields this week so we can schedule irrigation and pesticide application when conditions are optimal.”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/solar-intelWhen to prefer
Choose this endpoint when you need on-demand solar intelligence data (irradiance, space weather, solar flux) without setting up API keys or accounts, and are comfortable paying $0.02 USDC per call on Base mainnet via the x402 micropayment protocol.
Side effects
- Missing or invalid properties parameter returns malformed or empty response
- Insufficient USDC balance on Base mainnet results in 402 payment required error
- Network or blockchain confirmation delays cause timeout
- Unsupported property key returns null or error payload
- Rate limiting or service unavailability returns 5xx error
