Abstract
The sun is one of renewable energy sources. The use of sunlight using solar panels as a power plant began to be developed to reduce the use of fossil fuels. Solar panels have the advantage of being environmentally friendly because they do not have pollution-generating waste, are inexpensive and easy to apply. The power generated by solar panel is influenced by temperature and light intensity factor. The main problem of using solar panels is its efficiency is still low. This research presents an attempt to improve the energy conversion efficiency by solar panels by using Maximum Power Point Tracking method. The main principle of this method is adjusting the output voltage from the solar panel to obtain maximum power for different intensity of sunlight. The solar panel output voltage setting is performed using a buck boost converter controlled by MPPT system. The simulation results show that the use of this method of solar panel output power is higher by 64,78% -87,06% than without MPPT.
Highlights
In the current energy crisis conditions, scientists are competing to find and examine the use of alternative energy sources to ensure the sustainability and availability of these energy sources. fossil energy as a major energy source is very limited and is subject to a threat of scarcity due to the use of such energy on a large and continuous scale
The conventional solar array controllers are forced to operate with battery voltage, so the solar array does not work at the maximum power point tracking
The model of circuit for Maximum Power Point Tracking (MPPT) is shown below: The two most important things in designing MPP tracker are the topology of the switch mode and the control mechanism
Summary
In the current energy crisis conditions, scientists are competing to find and examine the use of alternative energy sources to ensure the sustainability and availability of these energy sources. fossil energy as a major energy source is very limited and is subject to a threat of scarcity due to the use of such energy on a large and continuous scale. Solar power plants (photovoltaic arrays) are a new energy source and. Which is very promising to be developed in order to meet energy needs This power plant utilizes sunlight as a source of energy to generate power that continues to use its use both in small scale and large scale [1]. This new modified alternative energy sources have been put forward by previous researchers like Tri et al (2011) and Radhityo (2012), but to realize its large-scale utilization in our country Indonesia is experiencing delays, because it is related to development policy, as well as politics and understanding of society. By extracting the power from the photovoltaic array, it is expected that the storage of electricity in the battery is maximum and lasts continuously [5]
