Abstract

The electrical energy of solar power plants which integrated into the networks depends on the intensity of solar radiation. However, some solar power plant areas there are still present trees and buildings around it that can partially cover the surface area of ​​the solar panel (partial shading). This study aims to investigate the effects of solar radiation variability due to several partial shading conditions on the 1 Wp solar cell output power. Based on observations from 10:00 to 14:00, the open-circuit voltage and short circuit current in solar cells decreases with increasing intensity of partial shading. The greater the partial shading of the solar cell, the lower the power output will be. The half partial shading effect of the total solar cell area resulted in a power reduction of 88.2%. A quarter of shading causes a decrease in the output power of solar cells by 75.6% compared to the power output under normal conditions. In addition, the increase in the temperature of solar cells resulted in a significant decrease in the open-circuit voltage.

Abstract

The greenhouse system works by utilizing solar thermal energy. It has a deficiency because it depends on weather to get maximum solar thermal energy. This deficiency can interfere with the drying process of plantation products, especially gaplek. Therefore, biomass furnace is added to overcome the dependence of solar thermal energy. The result of the proposed hybrid dryer system can control the temperature below 60℃. Moreover, the humidity can reach a minimum point of 60% while the temperature is 57℃. Those results show the system can give nomerous dry air to the dryer room because the greenhouse system is equipped with an exhaust fan. Thus, gaplek can appropriately dry according to the desired grade. Then, the cost of operating the proposed hybrid drying system is inexpensive, which is Rp 158.194,65 per year.
