Solar output estimator & daily irradiance analyzer for Accra, Ghana using NASA POWER API
# Solar Output Estimator — Accra, Ghana
Estimates daily and monthly energy output for a residential solar PV system
in Accra, Ghana, using real satellite-derived irradiance data from NASA POWER.
## What it does
- Pulls a full year of daily solar irradiance and temperature data via the NASA POWER API
- Validates the data against known seasonal patterns (dry season vs. West African monsoon)
- Calculates estimated daily/monthly energy output for a 5kW residential system
- Visualizes both irradiance and output trends across the year
## Results
- Estimated annual output: **7,059 kWh**
