Estimation of global solar radiation in north-west geo-political of Nigeria has been carried out in this paper. Twenty years (2000-2020) data of daily global solar radiation and monthly average bright sunshine hours are sourced from National Aeronautics and Space Administration (NASA) and Nigeria Meteorological Agency (NIMET), respectively. The zone consists of seven states. Mean global solar radiation estimated in the zone is 72.50 kW-hrm-2day-1 and monthly values ranges in value from 0.44 – 0.68. Thus, most days in the zone are adjudged to be cloudy. Monthly bright sunshine hour in the zone is estimated at 96.57 hrs. Four seasonal classification periods are determined for Duste, Kano, Bernin-Kebbi, Sokoto, Gusau, and Katsina. Kaduna recoded five season classification patterns. Angstrom-Page equation is developed for the zone and study locations and applicable in locations with similar meteorological conditions..
