iqbal

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…
