Abstract:
Nowadays solar is one of free source that had been used. The country that
have hot weather is an advantage because it can used solar energy is main or
alternative supply but solar also have disadvantages. Solar are slightly pricy
and the power generation only can produce maximum capability on day at
peak hour which is 12pm to 3pm. There are an alternative had been made to
overcome this disadvantage which is the development of solar tracker. Solar
tracker is one alternative that can overcome disadvantage of solar panel by
tracking the sun from morning until evening depends on sun position. With
solar tracker, solar panel can improve the maximum capability in the morning
and evening although the time is not in peak hour. Solar tracker can increase
the solar output from 5%-20% depends on the tracker and weather. This
project conduct the development of solar tracker on how to build up portable
solar tracker by using servo motor and light dependent resistor. The result of
voltage, current and power between solar tracker and fix solar panel been
recorded in table and the percentages differences between this two panels
been calculated for references in improving solar tracker.
