The study is about to determine the efficiency of flexible amorphous solar panel at
various radius of curvature and bending angle. The solar panel used was from Fe
Fuji Electric Co. Ltd. The materials and model of the solar panel is Amorphous
solar cell module, FPV1046DSJ2 with serial number F151118000103. The
experiment was conducted by shaping the solar panel into curve shape with various
radius. The experiment was done in dark room and using spotlight. Irradiance meter
was used to measure the intensity of light. The result showed that concave shape
has highest value of efficiency, 1.36% at radius 0.99 m than convex shape, 0.80%
at radius of 1.24 m. The study also determines the efficiency of thin-film solar panel
with tilt angle at time 10.20 a.m., 12.20 p.m., 2.20 p.m. the experiment was
conducted at open area, and using inclined plane to determine the angle. This
experiment was performed by using sunlight. The result showed that solar panel
obtain highest efficiency at time 12.20 p.m. with efficiency of 8.41% with angle of
40.2°
