Abstract aceh province is geographically located between 20- 60 lu and 950- 980 bt is a tropical region that has a high enough intensity of the sun. solar energy is a potential energy source, so it needs to consider aspects of the benefits brought about by the sun. this study aims to examine the variation of the solar collector tilt angle to get the collector with optimum results. the material used is wood frame with insulating material zinc in black paint. temperature measurements carried out in an open space with solar energy as a source of energy for heating. measurements were taken from 09.00 am - 17.00 pm with measurements every hour. thermometer was used to measure the temperature, where the measurement is made by 4 (four) points in each space of collector. the results showed that the distribution of the average temperature for the collector tilt angle of 150 c with the air flow rate 0.028 kg/ s is 80 c, the average temperature difference for collector tilt angle of 300 c with
