Sun Hours for Solar Panels

By Andy Mesa

Overview

Compare monthly sunlight data and calculate annual solar energy potential using NASA POWER historical averages. Choose a location, adjust system size and losses, and compare the seasons. Results are a rough horizontal-sunlight baseline; roof angle, local shading and actual meter output are not modelled. No inverter account is connected.

Tools

get_seasonal_solar_estimate

ChatGPT

Estimate monthly and annual solar potential from NASA POWER historical horizontal sunlight averages. Requires a location_ref selected by the user in the planner. No roof angle correction, weather forecast, savings or actual meter readings. Use for seasonal comparisons and a rough system-size baseline.

open_solar_planner

ChatGPT

Open the interactive solar calculator so the user can select a postcode or coordinates and system size. Calculate seasonal solar potential from open NASA data. Use when location has not been selected or the user wants a visual planner. No account or inverter access.

search_solar_locations

ChatGPT

Look up the postcode or coordinates explicitly entered in the solar calculator. Available only to the user interface. Returns matching location names and signed references. Does not infer a location or access device geolocation.
