Solar simulator plays a vital role in the research and development of solar photovoltaic, solar thermal and builds environment. Producing uniformity in spatial, temporal and spectral radiation distribution are the key parameters when developing a solar simulator so the sun radiation is matched as closely as possible in the laboratory environment. This paper presents a development of a solar simulator for education and research purpose. The objective is to achieve a uniform spatial distribution of radiation from a set of halogen lamps. The simulator was built with eight 500W halogen lamps powered by typical domestic 220 V source. The lamps are connected in two parallel four-in-series arrangement and placed perpendicularly from each other about halogen bulb axis. The distance between lamp reflectors edge was varied and total radiation measured by a pyranometer at various distance from the lamp. The findings showed that the optimal distance between reflector edges is 0.15 m which produced good spatially uniform radiation between 500 and 1100 W/m² at distance between 0.20 and 0.40 cm within the test area of 0.4 m².
