Abstract

Indonesia is a country which is get sun exposure throughout the year due to geographically located around
the equator. Utilization of solar energy as a source of renewable energy should be encouraged in order to
conserve the use of fossil energy sources dwindling availability. This paper presents the use of sun energy
as water heater (Solar Water Heater). The experimental method is studies comparing the performance of
solar water heater with genuine copper pipe collector and copper pipe which was coated a black paint. The
study was conducted in Cilegon area for all day from 08:00 am until 05:00 pm with a one hour sampling
period for 10 days. From data collector inlet-outlet water temperature and environmentally condition in
which testing is done, furthermore was calculated the energy absorption efficiency by solar water heater.
Theoretically, the absorption of energy radiation by a black body is the best. Results of the study is the pipe
collector with black paint coating had higher energy absorption efficiency up to 31 times than the copper
pipe collector with no coating.
